    Have you ever frequently put off things you should do for various reasons? If so, it is procrastination (拖延). Procrastinators often put off  doing things and leave them to the very last moment. 1.Lazy people simply don’t do anything and are just fine with it. Procrastinators, on the other hand, have the desire to do something but can’t force themselves to start.

You might think procrastination is a bit annoying but fairly harmless. However, long term procrastination has bad effects on your health. Not having seen the doctor when your illness was easier to treat may shorten your life. Just thinking about what you haven’t done may cause discomfort. 2.

Don’t place too much pressure on yourself. “This project has to impress everyone; I really can’t blow this opportunity,”  3. Overcome this mental block by simply allowing yourself to be imperfect with the next small task. You can always improve your work later.

4. Concentrating on the size and difficulty of a task will overcome you and promote procrastination. Any work can be broken into smaller steps. The trick is - with each step along the way — to focus on the next achievable tasks. Make sure you can easily imagine the outcome of your small task. Don’t write a book; write a page.

Focus on starting, rather than finishing. For someone who’s having a hard time starting a task, imagining a hard-to-grasp future can be depressing. The solution in this case, then, is to focus on starting. 5. We all know that if we start, we’ll eventually finish the task.

A.Break a long project down into short tasks.

B.So procrastination is about managing the time.

C.So we should apply ourselves to overcoming it.

D.However, procrastination is different from laziness.

E.Focus on the negative effects of the procrastination.

F.Bring your focus from the future to what can be done right now.

G.Placing such high hopes on a project only adds anxiety and fear of failure.

    We know them when we see them: The TV shows and movies we love, even though we just know they’re bad. The worthless books we simply can’t put down.

Yes, these are our guilty pleasures — what some people consider the junk food in our media diets. But if we enjoy them, why should we feel guilty? As it turns out, these so-called “guilty” pleasures can actually be good for us, so long as they’re enjoyed in moderation.

According to Robin Nabi, a professor at the University of California, a guilty pleasure is something that we enjoy, but we know we’re either not supposed to like, or that liking it says something negative about us.

Studies suggest that guilty pleasures can bring back some psychological resources. Besides, giving ourselves permission to enjoy downtime is also an important part of self-pity, which is an effective way of fighting anxiety and sadness. Perhaps the most important value of a guilty pleasure is the bond it can create between people.

If that’s true, why do guilty pleasures get such a bad reputation? Actually, it’s not the indulgences themselves, but the attitudes we take when talking about them. “We have the cultural value of media consumption being instructive, and that what we do should be about growing and achieving,” Dr. Nabi said. “We don’t focus as much on refreshment and enjoyment, and these are such important aspects of being a human being.”

Feeling guilty about activities we enjoy can diminish the benefits they offer us. But removing unnecessary embarrassment about our interests can enrich our social lives, which is why it’s time to get rid of “guilty pleasure” from our vocabulary.

While guilty pleasures benefit us in some cases, they can also push us to indulge in behaviors we feel guilty about. Therefore, it’s best to follow the age-old advice our parents taught us: Everything in moderation.

1.Which of the following might make us feel guilty pleasure?

A.Eating an entire bag of chips in one sitting. B.Telling an old bedtime story.

C.Staying up late doing your homework. D.Giving up seats to the elderly.

2.Why do people think poorly of guilty pleasures?

A.They take guilty pleasures too seriously. B.They dislike the behaviour of indulgence.

C.They ignore the benefits of guilty pleasures. D.They are influenced by their cultural value.

3.What does the underlined word “diminish” in paragraph 6 mean?

A.Reduce. B.Increase. C.Maximize. D.Destroy.

4.What is the best title for the text?

A.Guilty pleasure? Avoid it B.Guilty pleasure? No Such Thing

C.Everything in Moderation D.New Trend in Media Consumption

    Over a four-year period, Swiss researchers have developed a machine that can keep human livers (肝)alive outside of the body for one week.

Livers are among the most commonly transplanted (移植)human organs. Current technology can only keep human livers alive for up to 24 hours. It is reported that, in 2017, about 8.000 liver transplants were performed in the U.S., of which 360 used livers from living givers In addition, about 11,500 people were registered on a waiting list to receive a liver transplant. Keeping livers alive and functioning for longer periods could greatly improve the chances of survival for patients.

The researchers say the purpose of their “Liver4Life” machine is to perform what they call liver perfusion (灌注)operations outside of the human body. Perfusion is the process by which blood or other liquids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. Using a pump to fill the liver with blood acting like a human heart, the machine also provides oxygen to the organ, controls red blood cell levels and removes waste.

The research team began their experiments with livers from pigs. After repeated testing and engineering development, they succeeded in getting the pig livers to survive for seven days with support only provided from the Liver4Life machine. They also discovered the system can work to repair damaged livers. The team is now planning its next step to transplant machine-treated organs into patients.

Pierre-Alain Clavien. leader of the research said in a statement. “This technology will greatly increase the number of livers available for transplant, improving the chances of survival for patients. The success of this unique machine opens the way for many new applications in transplantation and cancer medicine.”

1.What does the author intend to do in paragraph 2?

A.Introduce a brand new topic for discussion.

B.Provide some latest data about present liver transplants.

C.Show the urgency of tech improvement in liver transplants.

D.Remind readers concerned of the importance of a healthy liver.

2.What does the underlined word “it” in paragraph 3 refer to?

A.The machine. B.The liver.

C.The temperature. D.The tissue.

3.What can we learn about the Liver4Life machine?

A.It is among the most commonly used machines for liver transplants.

B.It is aimed to carry out liver perfusion operations in the human body.

C.It can perform several functions to keep the liver working normally.

D.It can be used to keep the pig livers alive for more than one week.

4.Where is this text most likely from?

A.A biology textbook. B.A first aid brochure.

C.A social web page. D.A health magazine.

    A few weeks ago, I picked up my 14-year-old daughter and her friend from dance class. The two girls chatted happily until I reached her friend’s house. And then 1 began the drive home and my daughter, who had been talking nonstop a minute before, went completely silent. I assumed she was lost in thought.

When I came to a stoplight, I looked in the mirror. My daughter wasn’t looking out of the window or staring into space - she was on her phone. I felt my anger rise.

“Get off your phone. That is rude. You make me feel like an Uber driver.” I shouted.

“But I’m texting friends about biology homework!’’ she said.

“That can wait.” I was mad and she was angry.

Back home, she disappeared into her room, and I thought about how I was still trying to take control of my daughter’s growing independence, which was fruitless.

The next day I was thinking about my outburst when a parenting program on TV caught my eye, in which the hosts interviewed Dr. Ken Ginsburg, the author of a famous parenting book. It completely changed my attitude.

Ginsburg said. “Why are our teens pushing us away? It’s not because they hate us - it’s because they love us so much and yet they know they have to become independent. So this is a process of figuring out how to push away the things they love the most. It is crazy to fly from a comfortable nest, so teens get ready for it by temporarily pushing their parents away.”

I need to honor her independence and create space for both of us to face this monumental developmental challenge as teammates, not adversaries((对手).

1.What made the writer mad?

A.She served as an Uber driver.

A.She is being under her mother’s control.

B.She is on the way to being independent.

3.Which of the following best describes the mother?

A.Open-minded. B.Hardworking.

C.Inspiring. D.weak-willed.

4.What is the passage mainly about?

A.I was pushed away by my teenaged daughter.

B.Life of a teenager is moving at its own slow pace.

C.Parents completely rely on parenting experts to educate children.

D.My relationship with my daughter was improved by a suggestion.

Holidays are not necessarily for fun or rest. Doing something meaningful can also gain  special pleasure. When the final bell rang, the students were reminded that there was no  school on Monday—the Labor Day. “Enjoy your extra day off,”said the teacher to her class.

An extra day of fun suited Kayla just fine. She loved breaks. She wanted to go out to play with her friends. When the school bus dropped Kayla off, she ran into the house happily.

“How was school, Kayla?” asked her mom.

“It was great, Mom. I am excited about no school on Monday. ”

“You just started back to school two weeks ago. Already in need of a break, huh?” asked Kayla’s mom with a laugh.

Kayla slept in the next morning. Saturday was her favorite day of the week. It rained most of the day, so Kayla enjoyed playing video games inside. On Sunday, her friends came over and they played basketball for several hours.

Then it was Labor Day, you know, the extra day off that Kayla was so looking forward to. But Kayla was awakened early that morning by her dad. He told Kayla that in honor of Labor Day, the family would be cleaning both inside and outside the house. Kayla couldn’t believe it. This was a holiday. A day when she was supposed to be enjoying freshly squeezed lemonade while playing in her tree house. As Kayla wiped her eyes, she began to wonder if this was just a bad dream.

“Kayla, your breakfast is ready. We have a lot of work to do today. Let’s get a move on, ”said Kayla’s mom. As she sat down at the kitchen table, Kayla asked her parents,

“Are you serious about working today? Isn’t Labor Day a holiday?”

“Yes, Kayla. It is, ”replied her dad. “But your mom and I thought working hard today would make you appreciate why Labor Day was observed in the first place. ”

Paragraph1：

At first, Kayla felt disappointed at her parents’ plan for the holiday.

    Experts agree that parents who give up control over their children’s lives would raise them to be more independent adults. While most parents are not in the position to bribe their children into elite (精英) schools, this extreme case shows the temptation many feel to take control of their kids, lives. But an extreme approach can have devastating (毁灭性的) consequences when it comes to a child’s mental health.

“These parents thought their kids were not able to manage their lives by themselves. And I don’t think there’s any worse message you can give somebody than ‘I don’t have any confidence in your ability to handle your own life,’” the neuropsychologist William Stixrud told HuffPost. Stixrud is the author of The Self-Driven Child: The Science and Sense of Giving Your Kids More Control Over Their Lives, along with Ned Johnson.

In their research, Stixrud and Johnson have showed the importance for young people to feel a sense of control I over their own lives. “They have many problems like anxiety and depression, and those are related to the fact that kids feel so little control over their lives,” said Stixrud. “They feel like, ‘Here’s a script to get into college, and that’s what your life is going to be.’ It’s too stressful and discouraging for many kids.” In order to develop healthy self-motivation, young people need to feel a sense of confidence and control, which parents and educators have the power to promote.

“We suggest parents think of themselves as advisors, rather than a kid’s manager or boss, or the homework police. It’s a very different kind of thinking about your role,” said Stixrud, “As all advisor, your role is not to force anything or say ‘You need to be like this. ’ Instead, help your kid understand what he or she wants to be.” He advises parents to encourage their kids to make their own decisions long before the college years. It’s important to constantly ask, “Whose life is this?” and realize the answer is “My child’s life, not mine.”

1.What does the writer think of the extreme approach in parenting?

A.It’s harmful to children’s mental health.

B.It can raise children to be independent ones.

C.It can have devastating consequences physically.

D.It can help children to be admitted into better schools.

2.Why do some parents control their children’s lives so much according to Stixrud?

A.They want to be considerate in every aspect.

B.They think much stress is good for the children.

C.They don’t want their children to be independent.

D.They have no confidence in their children’s ability.

3.What does the author intend to do in the last paragraph?

A.To summarize the previous paragraphs.

B.To provide some advice for parents.

C.To add some background information.

D.To introduce a new topic for discussion.

4.Which could be the best title for the text?

A.How to Be Your Children’s Friend

B.Allow Your Children to Grow at Will

C.Be Your Children’s Advisor Instead of Manager

D.How to Help Your Children Adjust to College Life

    Scientists at Israel's Tel Aviv University say—they have created the world’s first 3D-printed heart with human tissue and blood vessels. Although the organ is only as big as a rabbit’s heart, the researchers are hoping the technology could one day be developed enough to help human patients in need of a heart transplant.

Lead researcher Tal Dvir said that while other scientists have managed to 3D—print the structure of a heart in the past, this is the first time anyone has printed an entire heart. “Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future,”Dvir said in a press statement.

Scientists used fatty tissue taken from human patients to create the heart. Some material in the tissue was reprogrammed to become stem cells. The remaining material was processed into a hydrogel. They used the hydrogel as a printing：“ink”. This method is key to removing the risk that the implant will be rejected by the patient’s body. The team’s next step is to cultivate the organs in a lab and to teach them how to“behave”like hearts. Dvir’s 3D-printed hearts can currently contract, but the cells still need to develop a pumping ability. His team eventually plans to test the hearts in animals.

“Maybe, in ten years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely, ”Dvir said. Heart disease is the leading cause of death for both men and women, according to the Centers for Disease Control and Prevention. About 610, 000 people die of this disease in America every year—amounting to about 1 in every 4 deaths. There are currently more than 3700 people waiting for a heart transplant in the United States, according to data from the United States Department of Health and Human Services.

    It was a Saturday evening in March，just before sundown，when we heard the screaming. I was out walking with my wife，Melissa，and our golden retriever(猎犬)，Kira，beside a lake when the peace was broken by a woman’s voice，calling out two names over and over.

We spotted her，almost immediately，three or four hundred feet away across the lake. Spring had come but there was still snow on the ground，the water covered by a layer of ice that had just started to thaw. Two big dogs were walking across it. They appeared to be quite old and were moving slowly. As we watched，the ice gave way beneath one dog and then the other，plunging them into the water.

We arrived at the scene a few minutes later，but the dogs already seemed to be showing the effects of the cold as they struggled weakly to escape. We realized that calling 911 would be useless—the dog farther out was in water about 20 feet deep and I feared neither of them would stay afloat long enough for the emergency services to arrive. Besides，I was probably qualified to carry out the rescue myself. I was practicing the kind of deep breathing my grandfather had taught me as I walked in. I wasn’t alone—Kira swam alongside me. Having Kira there was a huge support. We were able to go back to shore quickly.

The second dog was further out and I had to pause before I went back in. That’s when another technique I’d learned from my grandfather came into play. He’d taught me about a pressure point on the wrist that when pressed in the right way sends out an electrical signal，like a jolt of energy. That kept me warm as I set out again with，Kira. I maintained eye contact with the dog as we approached. With Kira’s encouragement，it followed us back. The owner was emotional—“I’m the luckiest woman alive!”she said.

D.The writer’s grandfather had taught him how to save the dogs.

3.What do we know about the second technique the writer learned from his grandfather?

A.It makes him brave. B.It keeps him warm.

C.It allows him stay focused. D.It helps him walk quickly.

4.Who accompanied and helped the writer while saving the dogs in the water?

A.His wife. B.The dogs’owner.

C.His grandfather. D.His dog.

    While gardens can be a great place for pets to explore and play, some seemingly harmless plants and gardening products can be poisonous for animals or pets. Here are the garden products to avoid:

Cocoa mulch

Some gardeners like to use cocoa shell mulch in their gardens but, just like chocolate, cocoa shell mulch contains theobromine (可可碱), which is poisonous to dogs. This means that cocoa shell mulch can be potentially deadly if consumed in large quantities. If you own a dog I’d strongly advise that you avoid using Cocoa mulch in your garden.

Compost

Despite being an eco-friendly garden feature, compost can be highly dangerous for animal. As organic matter decomposes, it releases mycotoxins (霉菌素), which are poisonous to wildlife. Consumption of mycotoxins can cause panting, vomiting (呕吐), seizures and even death in dogs. If you do use compost in your garden, make sure it is securely fenced off so that your pet cannot access it.

Weed killer

The chemicals contained in weed killers can be irritants to animals and, in some cases，even poisonous. Some weed killers contain harmful substances, such as borax and arsenic, which can potentially be fatal to pets. If you are unsure whether a weed killer is safe to use in a garden that your pet uses, you should always seek the manufacturer’s advice first, or ask a vet (兽医).

Fertiliser

Different fertilisers can contain a wide range of ingredients, including insecticides, fungicides and bacterial. The caustic nature of some fertilisers also means that, if consumed, they can cause stomach upsets for pets. Some fertilisers can also cause more serious symptoms, such as vomiting, muscle tremors or even death, so keeping your garden fertiliser free is the simplest way to ensure that it is pet friendly.

If you think your pet has eaten something they shouldn’t, or if you have any other concerns about your pet’s health, you can call the video vet service FirstVet at any time of day and speak with a qualified UK vet.

It is common that some people can accomplish very tough tasks while other can’t. In reality, no one can always avoid difficulties in life, but the results are quite differently. The difference lay in people’s different attitudes. Some people choose to face hardships bravely. We are determined to reach their destinations how many times they fail. Therefore, it’s just their perseverance which helps them make it in the end. Others may easily give up to whatever obstacle they meet, which can lead to nothing but failure.

In my view, keep on doesn’t necessarily mean success, but giving up absolutely means failures. If we can adopt such positive attitude, we are bound to achieve more than we expect.
