A
Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body—and the body from them—until they can be released at just the right spot. There are lots of ways to trigger (引发) this release，including changing temperature, acidity, and so on. But triggers can come with their own risks—burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining nearinfrared light (NIR, 近红外线) on the drug in the capsule.
The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV, 紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds (化合物) absorb NIR well and go through chemical changes.
That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIRabsorbing group called
onitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a soso NIR absorber, and it could be poisonous to cells when it separates from the polymer.
So Almutairi and her colleagues reported creating a new material for capsules that's even better. This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive (易反应的) components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a lightabsorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. What's more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.
63. According to the passage, which of the following could be the best trigger?
A. Temperature change.
B. NIR light.
C. Acidity change.

64. Why is ONB unsatisfactory?
A. It breaks down when it absorbs NIR light.
B. It falls off the polymer and triggers drug release.
C. It has not come onto the market up till now.
D. It is not effective enough and could be poisonous.
65. Which word can be used to complete the following process of changes?
⇨⇨⇨
A. protected

It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.
My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’m so glad I did.
On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all， it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby. We couldn’t beliee it ——there aren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale棗vactually as big as our boat棗twas obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools(漩涡) and waves. ”She’s trying to help her baby, but on the wrong side, ”my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, some-times rising from the water right beside us to breathe棗gand to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day, Nearly four decades later, I still look back fondly to that golden day at sea.
51. The author says “I’m so glad I did. ”(in Para. 2)because __________.
A. he witnessed the whole process of fishing
B. he enjoyed the beauty of the calm sea
C. he experienced the rescue of the whales
D. he spent the weekend with his family
52. The harbour survived the storm owing to____________.
A. the shape of the harbour
B. the arms of the bay
C. the still water in the channel
D. the long coast line
53. The mother whale failed to help her baby because__________.
A. she had stayed in the polluted water for too long
B. the whirlpools she had made were not big enough
C. she had no other whales around to turn to for help
D. the waves pushed her baby in the wrong direction
54. what is the theme of the story?
A. Saving lives brings people a sense of happiness
B. Fishing provides excitement for children

【江苏泗阳中学2017届第一次模拟考试】
Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice -skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.
Stand Straight
The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.
Confidence is What You Need
The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slop every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris （碎片） because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor （做剪式运动） your skatesKeep practicing this till you are confident about it.
Maintain Speed
Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling （滑浆）, that is, keep pushing yourself backwards with an outwards stroke （滑动）Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.
Increase Your Speed Now
Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.
Scull and Be Aware
While you keep one foot straight, keep sculling with the other. You can do that simultaneously （同时，一起） with both feetConcentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.
