China’s first overpass for wildlife migration has already come into use. The bridge 1.(lie) over the newly constructed National Highway 214 is able to link animal habitats separated by the road. 2.(cover) with sand―much like the surrounding land, the overpass can fit in with the environment well.
It’s about two years since the national highway 3. (begin) and it is designed with environmental protection as a top priority. A project environmental engineer for the highway said they based the construction of these man-made corridors（通道）4. years of observation of wildlife migration in the region. The bridge, for example, is built according to the region’s natural conditions and with 5. purpose of reducing the highway’s effect on the animals significantly. Wildlife overpasses and underpasses assist animals 6. (safe) crossing over or under busy roadways and allow them to continue to use their customary paths, 7. would otherwise be blocked.
Those passageways, with a total 8. (long) of 59 kilometers, enable antelopes and other animals to cross the railway freely. So far, China has put great effort into achieving 9. (harmony) coexistence between human development and the protection of wildlife. The Qinghai-Tibet Railway, the world’s 10. (high) railroad, has 33 underpasses for migrating animals.

Much meaning can be conveyed clearly with our eyes, so it is often said that eyes can speak.
Do you have such kind of experience? 1., but not too long. And if he is sensing that he is being stared at, he may feel uncomfortable.
2.. If you are looked at for more than necessary, you will look at yourself up and down to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward other's stare with you that way. Eyes do speak, right?
3.. But things are different when it comes to staring at the opposite sex. If a man glances at a woman for more than 10 seconds, his intentions are obvious, that is, he wishes to attract her attention to make her understand that he is admiring her. In fact, continuous eye contact occurs between lovers only, who will enjoy looking at each other tenderly for a long time to show affection that words cannot express.
However, the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener is attentive. 4., as if he tries to control you, you will feel uncomfortable. A poor liar usually exposes himself by looking too long at the victim, since he believes in the false idea that to look straight in the eye is a sign of honest communication. 5..
Evidently, eye contact should be done according to the relationship between two people and the specific situation.
A. Quite the contrary
B. The same is in daily life
C. In a bus you may look at a stranger
D. Looking too long at someone may seem to be rude
E. This shows the listener is interested in your speech
F. If a speaker looks at you continuously when speaking
G. Sometimes it doesn't matter to look at someone too long
For many Daylight Saving Time (DST:夏令时) simply means remembering to change the clocks and twisting your sleep schedule. “Even though the time change is only an hour, it is something that causes much more destruction than people believe,” said Dr. John Sharp, a psychologist and psychiatrist at Beth-Israel Deaconess Medical Center in Boston. “It’s not just an extra hour of sleep; it’s more of a fast-forward into winter.”
With days getting darker earlier, Sharp suggests making a to-do list for activities after work ahead of time. “Any plans you have, say, going to the gym after work, require much more effort and determination. It’s much better to plan more carefully and not just rely on how you feel, especially when it is dark out,” he said. “Figure it out in advance and stick with the plan.”
In addition. Sharp says in the weeks after Daylight Saving, some may feel like they have a bigger appetite. “Eating more during this time is not the answer. People need to stay on an eating schedule and keep up healthy habits. ”
However, Sharp said there are ways to better acclimate yourself to the time change. If you are having trouble sleeping, he suggests taking some melatonin (退黑激素) in the evening. In contrast, if you find yourself feeling sleepy. Sharp said there is nothing wrong with adding an extra caffeinated drink during your day.
A word to the wise? One sure way to better adjust to the time change is to start going to bed 15 minutes earlier starting four days before Daylight Saving, adding an additional 15 minutes each night.

If a diver surfaces too quickly, he may suffer the bends. Nitrogen(氮) dissolved(溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡)accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles form in his lungs or his brain, the consequence can be death.
Other air-breathing animals also suffer this decompression(减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil (化石)bones that have caved in on them selves are thus a sign that the animal once had the bends.
Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.
When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen(标本) showed evidence of that sort of injury.
If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened. He suspects it was evolution in other animals that caused the change.
Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark- and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey(猎物) as well as predator—and often had to make a speedy exit as a result.
1.Which of the following is a typical symptom of the bends?
A.A twisted body. B.A gradual decrease in blood supply.
C.A sudden release of nitrogen in blood. D.A drop in blood pressure.
2.The purpose of Rothschild’s study is to see________ .
A.how often ichthyosaurs caught the bends B.how ichthyosaurs adapted to decompression
C.why ichthyosaurs bent their bodies D.when ichthyosaurs broke their bones
3.Rothschild’s finding stated in Paragraph 4________ ..
A.confirmed his assumption B.speeded up his research process
C.disagreed with his assumption D.changed his research objectives
4.Rothschild might have concluded that ichthyosaurs ________ .
A.failed to evolve an anti decompression means
B.gradually developed measures against the bends
C.died out because of large sharks and crocodiles
D.evolved an anti decompression means but soon lost it
When you hear the word “birthmark”, you probably think of one of those black or brown spots that you have on your body. For me, it’s different―I have them on my lips and inside my mouth. I’m used to being asked, “What are those black marks on your lips?” When I tell people they’re birthmarks, they usually say, “That’s strange.” I used to consider them ugly. However, my mom calls them beauty marks.
In pictures, I used to hide my birthmarks by pursing (噘起) my lips so I wouldn’t ave to deal with people’ s questions, As I was growing up, people wore me out with them. Some people would ask me the same questions even before knowing my name. In society I feel like we judge people by their looks before their personality.
My birthmarks are caused by a genetic condition from my mom’s side of the family, My mom’s mom has birthmarks on her lips, and my mom’s uncle and my uncle have some on their bodies. Every year I plan to have procedure to remove them. But when imagining the process, I always get nervous and give up.
My cousin faces a similar challenge. She has a huge birthmark that takes up her whole arm. She’s never tried to hide it or change her appearance. Once, her grandmother told her that the birthmark looked extremely prominent and suggested that she should wear long sleeves more often. If my cousin had actually taken that suggestion, she wouldn’t be such a person as she is.
Inspired by my cousin, I am finally accepting who I am and now I don’t hesitate when someone asks me about them either. I say, “They’re beauty marks” and smile without pursing my lips.

A.She dislikes talking about her birthmark.
B.She never judges others by their looks.
C.She is more confident than the author.
D.She has taken her grandma’s suggestion.
4.What does the underlined word “prominent” in paragraph 4 mean?
A.Brilliant. B.Symbolic.
