Several years ago, my tire went flatly while I was driving with my young son who was being asleep in the backseat. It was a heavily traveled road, but I pulled over. I looked my mirror and saw that the man had pulled up behind me. He offered to help. As he installed the tires, we talked. What surprised me was which he was from a long distance away. His face was kind, his voice gentle. My son awakes, and I went to care for him. When I looked back, the man was going. Do angels exist? I believe we do.
My Ph.D. adviser called me into his office and started by saying, “Anurag, this conversation isn’t going to be easy.” My mind was instantly ________ into a burst of thoughts about what was to follow. He looked me in the eye and announced, “You are fired from the lab.” I stared back in ________, “Is he joking?”
I ________ my Ph.D. adviser, and my experiments progressed as planned. Though I made a few mistakes in the lab, I wasn’t ________ that my adviser noticed them, and he never spoke to me about any concerns. That’s why I was caught ________ in his office that day. I suspect he fired me because of those mistakes. He wasn’t ________ that I could complete my research.
I tried to change his mind with ________ results, but he remained unchanged. I was soon thrown into a state of ________, and I could not break the news to my family.
________ I collected myself. I thought of a movie, one line from which ________ to me: “When life gives you lemons, make lemonade (柠檬汁).” What kind of “lemonade” could I make out of my current ________?
My desire to complete a Ph.D. was never in doubt. After much ________, I reminded myself that one ________ attempt was not the end of the world, and that I needed to give it another try.

Are you an angry bird? When you’re angry, your body becomes tense. 1. Here are some other simple tricks to chill and think before you act.
Understand your anger
Think like a detective and track down clues about the kinds of situations, people, and events that set off your anger. 2. Even if you can’t get away from them, at least you’ll have more time to prepare for them so they don’t affect you so negatively. You can also think of the situation as an opportunity to practice not getting mad.
Go for a walk
When you get really angry, walk away from the source. A 5-minute walk outside or another calming activity like yoga are both great strategies for dealing with anger. If your anger arises from the traffic jam you’re stuck in, turn up the radio and sing at the top of your lungs. 3.
Write letters
4. So if you’re trying to calm down fast, grab your journal and write it all out. You can simply write your own feelings or try writing a letter to the person who upsets you. You never have to send it and just writing it will help you feel better.
Talk about your anger
It’s not just writing that helps relieve anger. 5. The trick is not to unload your anger on the person making you upset but to release your pressure by talking with a neutral (中立的) friend, family member, or specialist. A neutral observer can bring reasonable judgment to the situation. You can even try talking out loud to yourself about it.
Now that you’ve learned how to keep your anger in check, try some of these little changes that will make you a happier person.
A.Expressing it orally can also be incredibly calming.
B.Once you’re aware of them, try to avoid them if possible.
C.Writing out your feelings really does help you feel better.
D.The idea is to create a mental or physical escape from the situation.
E.Losing your temper makes you look like the bad guy to everyone else.
F.Deep breathing is just one of the ways you can instantly turn a bad mood around.
G.Exercise can help people lower their levels of anger and other negative emotions.
Nowadays medical technology seems to be advanced enough for doctors to perform brain transplants (移植). Though this procedure has only been successfully performed on animals so far, doctors are still hoping to perform this procedure on humans. However, in my opinion, brain transplants should not be performed at all, especially not on humans because of the large number of problems and side effects that could come along with. Hopefully these dangerous side effects will convince doctors not to perform this procedure on humans.
Despite many benefits technology brings, I do not think this medical technology of brain transplants will help. We were all born with one brain and through childhood to adolescence our mind developed into who we are, so if with a different brain we would no longer be unique. A person with a different brain would seem to be a total stranger and in many ways they would be. No one should steal our identity from us, even if we are seriously injured, and change it to a completely new one. Also for the people who have died with healthy brains, that was their identity and it should not be given to anyone else.
Another problem with brain transplants is how doctors can choose what are “healthy” or “normal” brains. An elderly person who has died would have an aged brain that would not be as efficient as a younger person’s brain. Then would doctors have to find healthy brains of the same age as the person who needs it? This could also bring up other factors such as intelligence, gender, or physical problems that a person might have had before death. Also another problem might be how long a brain can be kept “alive” after death and how it can be kept “alive” without damage.
Overall, my feelings about this surgery are that it should not be done on humans until doctors have overcome all the problems and obstacles (障碍) that stand in their way of making human brain transplants successful.
1.Why does the author think brain transplants should not be performed at all?
A.The cost of the surgery is extremely high.
B.Doctors are not able to perform brain transplants.
C.A good many problems and side effects may arise.
D.This procedure has only been successful on animals.
2.What is the second paragraph mainly about?
A.People shouldn’t give their healthy brains to others.
B.Having a brain transplant means losing one’s identity.
C.Transplanting brains is changing old brains into new ones.
D.Having brain transplants indicates stealing identity from others.
3.What do we know about “healthy” brains?
A.Aged brains aren’t healthy brains. B.Young brains are always healthy.
C.Healthy brains cannot be kept “alive”. D.It’s very difficult to tell healthy brains.
4.What is the author’s purpose in writing the passage?
A.To encourage brain donation.
B.To stress the importance of brain operation.
C.To argue against brain transplants on humans.
D.To introduce the technology of brain transplants.
When life gives you pineapples—and hundreds of millions of tons of pineapple waste—what do you do? Engineers in Singapore and Vietnam decided to tum all the waste into something useful—the heat barrier for their pineapple juice. Not only does their new material keep drinks cool better than many commercial coolers, but it could also offer a final resting place for the world’s pineapple waste.
To find a use for those leftovers, the researchers mixed pineapple fibers, which they cut up in an electric device, with a sticky agent as a solvent. They then treated the mix with sound waves at frequencies greater than 20 kHz and heated it in an oven at 80℃ for 2 hours. The suspension that formed was then cooled before being freeze-dried.
The result was a pale yellow aerogel (气凝胶) that is lightweight, flexible, and more than 96% porous (多孔的)—qualities that make it an ideal material against both heat and sound.
When the researchers wrapped a sheet of the pineapple aerogel around a military-style canteen bottle, they found that the aerogel could provide three times the heat exchange reduction of commercially available alternatives—they reported this month in Materials Chemistry and Physics. The gel-wrapped bottle kept -3℃ water cooled below 0℃ for 6 hours and liquid heated to 90℃ above 40℃ for 2.5 hours. What’s more, the pineapple gel also acted as a sound barrier; in another test, the gel did a better job of preventing noise from getting in or out than Basmel, a popular kind of sound barrier.
The findings provide a new, eco-friendly approach to recycling agricultural cast-offs—and a good excuse to get a better electric device for your kitchen.
1.Why do engineers come up with the idea of the heat barrier?
A.To lower the cost of heat barriers. B.To make good use of pineapple waste.
C.To find a better cooler for pineapple juice. D.To turn pineapples into something more useful.
2.What is the last step of making the pineapple aerogel?
A.Freeze-drying the suspension. B.Cooling the formed suspension.
C.Cutting up the pineapple leftovers. D.Treating the mix with sound waves.
3.What can we learn about the pineapple aerogel from paragraph 4?
A.It kept the liquid heated to 130℃ for about 2.5 hours.
B.It kept the water cooled below -3℃ for nearly 6 hours.
C.It could be three times as effective as other heat barriers.
D.It did a better job as a sound barrier than as a heat barrier.
4.What is the best title for the text?
A.A Better Way to Keep Drinks Cool. B.An Alternative Way to Recycle Waste.
C.Pineapple Waste, a Wonderful Drink Cooler. D.Pineapples, One of the Most Common Fruits.
