    Negative thinking is one of the biggest obstacles(障碍) we face in experiencing happiness, but there's hope. Here are two strategies to help defeat your negative thinking.

1.When you're heading into a social gathering, you begin to wonder what if I don't connect with anyone. Am I even likable? Faced with this situation, do something that lifts your mood.2. For example, listen to a song that makes you smile or take a moment to appreciate people in your life who love you. Positive emotions literally undo the effects of anxiety by lowering our heart rate and muscle tension.

The other is to combat(战斗). 3. But in reality, our minds feed us messages that range from the embellished(渲染的) truth to total lies. Imagine yourself in court. You are the prosecutor(控方律师), and your negative thought is the defendant(被告).4.When he shouts out “You're not good enough at your job”, you need to consult the evidence you have to prove it wrong, argue back with the strongest piece of evidence you can find. Always remember your task is to get the judge to hear your side. So you can say “I am good enough because every performance review I've had has been positive. And my boss told me last week how much she enjoyed working with me. “In a nutshell, bring your best version of a tough lawyer to that courtroom. Convince the judge that the negative thought doesn't deserve attention.

Both of these strategies, to distract and combat, are skills anyone can learn and get better at with practice.5.

A.He's guilty, but he insists that he's not guilty and sticks to his story.

B.Therefore, negative thinking is one of the biggest problems lots of us suffer from.

C.Remember, with each negative thought you defeat, you’ve successfully earned your own happiness.

D.That is, generate a positive emotion.

E.We often believe that our negative thinking is true.

F.There's simply no point focusing on the negative aspect of everything.

G.One is to distract.

Time Travel

If you could travel in time,where would you go?Perhaps you would watch a performance of a Shakespeare's play in Elizabethan England?What about hanging out with Laozi in the Spring and Autumn Period?Or maybe you'd voyage far ahead of the present day to see what the future holds.

The possibility of time travel is indeed appealing.Stories exploring the subject have been around for hundreds of years.Perhaps the best known example is science fiction novel The Time Machine,which was written by H.G.Wells and published in 1895 for the first time.It was adapted into at least two feature films of the same name,as well as two television versions, and a large number of comic book adaptations.It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively.The term"time machine",coined by Wells,is now universally used to refer to a vehicle transporting people into the far future.

But could time travel actually be possible?Some scientists say yes,in theory.They propose using cracks in time and space called"wormholes",which could be used as shortcuts to other periods.Einstein's theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking says you could travel into the future with a really fast spaceship-going at nearly the speed of light.Though building such a spaceship would of course be no simple task.

Even if you could travel into the past,there is something called the"grandfather paradox".It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason,and therefore prevent himself from being born.If the time traveler wasn't born,how would he travel back in time?

And would you really like to visit the future?In H.G.Wells' book,the main character travels into distant time where he arrives at a beach and is attacked by giant crabs.He then voyages 30 million years into the future where the only living thing is a black object with tentacles(触角）。

If that's what's in store,maybe we are better just living in the present day after all.

1.The novel The Time Machine mentioned in Paragraph 2 aims to show______.

A.the long history of time travel

B.the contribution of H.G.Wells

D.There are films,comic books and dramas adapted from the novel The Time Machine.

3.Einstein's and Hawking's theories______.

A.have similarities because both are based on experiments

B.suggest the possibility of time travel

C.have been proved wrong by some time travelers

D.have pushed the invention of the first spaceship

4.In Paragraph 4,"grandfather paradox”probably refers to the idea that______.

A.the reunion of the traveler and his grandfather brings happiness

B.the traveler is prevented from meeting his grandfather

C.the traveler goes back in time to seek for his grandfather

D.the grandfather's death makes the traveler's birth impossible

    When we talk to our friends online,typing can become a little boring.More often than not,we turn to memes(表情包）to make our conversations more fun. But sometimes, sending the wrong meme can mean trouble.

At least 10 students who were admitted to Harvard University lost their chance to study there after posting offensive memes in a private Facebook group, the university’s student newspaper, the Harvard Crimson, reported on June 5.In fact, this was not the first time Harvard had dealt with a case like this. Instead of regular jokes, the memes “went to truly dark and ugly places, joking about Orthodox Jews, the Holocaust and Mexican children,” reported CNN.

At first,the group was meant for would-be Harvard freshmen to get to know each other before they began university.But later,some students set up another group where they traded several offensive memes.When Harvard University found out about the group, it took back the students’ offers.

The incident has caused fierce debates, both in the university and around the world.

“I appreciate humor, but there are so many topics that just should not be joked about.” incoming freshman Jessica Zhang told the Harvard Crimson. “I do not know how those offensive images could be defended.”

However, others believe the university overstepped the boundaries. “It sounds like Harvard is intruding too deeply into the private lives of students, ”Alan Dershowitz, a retired Harvard Law School professor, told The Guardian, “It may affect them for life.”

The university didn’t explain the decision to withdraw the offers,saying it doesn’t comment publicly on the admission of individual applicants.But one of Harvard’s own policies says it has the right to withdraw offers of acceptance if “an admitted student engages in behavior that brings into question his or her honesty,maturity,or moral character”, according to the Harvard Crimson.

    Selena Gomez and I were scheduled to meet at a low-key coffee shop in Encino. Not wanting to keep the superstar waiting, I arrived at nine, 20 minutes early. As I was catching up on e-mails, Selena quietly scooted into the seat next to me. No bodyguard. Not even a drop of makeup. She was ten minutes early and so inconspicuous that no one else in the restaurant looked up so much. Selena was wearing Bebe shorts. She had a baby face and ordered a hot chocolate.

After making small talk about what she wore for the shoot, she dived into the subject of her career. Selena declared 2012 the year of movies. She filmed three: Spring Breakers, a drama; The Getaway, an action flick; and Hotel Transylvania, a comedy. Each is a marked move away from the teen style that made her a household name.

Now that her Disney days are behind her, Selena is at that unstable point in a child star's career where she is trying to grow up-both as a person (she turned 20 in July) and as an artist. “Being part of the Disney Channel was a blessing, and I'm super happy with what my show accomplished, but acting is something I would like to take on more seriously.” She continued, “I don't necessarily feel accomplished. I want to create a whole different persona when it comes to acting.”

Selena has been working full time since she was seven years old and scored a role on Barney & Friends. In 2007, when she was offered the lead in Wizards of Waverly Place, Selena, her mother, and her stepfather uprooted from Grand Prairie, Texas, to LA, where they are settling now.

1.When did Selena arrive at the low-key coffee shop?

A.At 10:00.

B.At 9:10.

C.At 8:50.

D.At 9:30.

2.The underlined word in the first paragraph probably means           .

A.unconcerned

B.graceful

C.not easily seen

D.always thinking of others

3.We can learn from Paragraph 2 that          .

A.three famous films made in 2012 have shown her teen style

B.Selena went into her film career as soon as we met in the coffee shop

C.each of the three films marks Selena's move away from her teen style

D.the film Hotel Transylvania is an action flick made in 2012

4.What did Selena think of Disney days which were behind her?

A.She thought of playing in Disney as an unstable point in her career.

B.She considered her being part of the Disney Channel a blessing.

C.She didn't feel very satisfied with her show in Disney.

D.She found herself not accomplished in her performance in Disney.

    Life satisfaction is the way persons evaluate their lives and how they feel about their directions and options for the future. It's a measure of well-being and may be evaluated in terms of mood, satisfaction with relations with others and with achieved goals and self-concepts to cope with daily life. It's having a favorable attitude towards one's life as a whole rather than just an evaluation of current feelings. Life satisfaction has been measured in relation to economy, education, experiences, and residence, as well as many other topics.

Life satisfaction can reflect experiences that have influenced a person in, a positive way. These experiences have the ability to motivate people to pursue and reach their goals. As a matter of fact, in these experiences there are two kinds of emotions that may positively influence how people understand their life. Hope and optimism both consist of emotional processes that are usually directed towards the reaching of goals. People who have higher life satisfaction are always full of hope for a better future; additionally, optimism is linked to higher life satisfaction, while pessimism is related to symptoms in depression.

The psychologist, Yuval Palgi, studied the old-old-people who were primarily in their nineties. This subject group was found to have thought highly of their past and present, but they thought lower of their future. A large factor that was talked about in life satisfaction was intelligence. The experiments talk of how life satisfaction grows as people become older because they become wiser and more knowledgeable, so they begin to see that life will be better as they grow older and understand the important things in life more. But when they step into their nineties, future becomes a luxury to them.

According to Seligman, the happier people are, the less they are focused on the negative. Happier people also have a greater tendency to like other people, which promotes a happier environment, which then correlates to a higher level of the persons' satisfaction with their life.

1.What can we learn about life satisfaction from Paragraph 1?

A.It can be easily measured through income and education.

B.It includes a positive attitude towards people's entire life.

C.It merely determines people's attitude towards the future.

D.It has nothing to do with the evaluation of current feelings.

A.The wealthier a person is, the happier he will feel.

B.Happy people are more likely to get along well with others.

C.Happy people won’t be influenced by the negative items in life.

D.Intelligence plays a leading role in determining people’s happiness.

3.What was the attitude of most old-old towards their future?

C.They felt satisfied with it. D.They were scared of it.

4.What may be the best title for the text?

    Vinegar makes salad，fries and dumplings taste better， and you can even use it to clean your windows． And now， according to scientists， it may even the planet's population survive climate change．

Researchers from the RIKEN Center for Sustainable Resource Science （CSRS） in Japan found that growing plants in vinegar makes them more resistant to droughts． This could mean that in the future， worries about climate change affecting the world's supply of food will be much lower． The discovery was made after the researchers studied the Arabidopsis， a plant known for its ability to survive in dry weather． It was found that when the plant was placed in drought﹣like conditions， it produced a chemical called acetate（醋酸盐）﹣the main component of vinegar．

After discovering this， the scientists experimented further by adding acetate to the soil of other plants， before they stopped giving them water completely． After leaving the plants for 14days， they found that the ones treated with acetate had survived， while the untreated plants had dried up and died．

It's hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive． "In the experiment， we targeted the staple foods of the world﹣rice， wheat and maize﹣and the basic plant of breeding species， rapeseed（油菜籽），" Jong Myong Kim， co﹣author of the study， told Popular Science magazine．

Kim also told the magazine he's already been in touch with people all over the world who are interested in trying this simple and cost﹣effective method out for themselves from flower growing companies to amateur gardeners． Although at this point keeping thirsty plants alive isn't as easy as just pouring vinegar over them， Kim said he and his team are working on making the process as simple as possible． "Now we are trying to cooperate with some farmers， and also some companies， to make a method to apply this system， "he said． And for those of us who always forget to ask our neighbors to water our plants when we goaway， hopefully this means the end of returning home from a trip to find our favorite flowers have died．
