The sea has always interested man. From it they can get food, minerals, and treasure. __1.__ But he could not go far beneath its surface __2.__. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems. A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases __3.__. He can carry a tank of air on his back and breathe through a nose and mouth piece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea _4.__. When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure less. If the diver rises too quickly, the gases in his blood form bubbles (气泡). The diver is then suffering from the bends (潜水夫病).The bends can cause a diver to double up in pain __5.__ .

If the eyes are the romantic’s window into the soul, then the teeth are an anthropologist’s ( 人类学家 ) door to the stomach.
In a study published last month in the journal Science, Peter Ungar of the University of Arkansas and his partner, Matt Sponheimer of the University of Colorado, US, examined the teeth of our early human ancestors to find out what they were really eating.
They already knew that different foods cause different marks on teeth. Some cause scratches, while others cause pits (坑).The carbon left on teeth by different foods is also different. Tropical grasses, for example, leave one kind of carbon, but trees leave another kind because they photosynthesized ( 光合作用 ) differently.
Traditionally, scientists had looked at the size and shape of teeth and skulls ( 头骨 ) to figure out what early humans ate. Big flat teeth were taken to be signs that they ate nuts and seeds, while hard and sharp teeth seemed good for cutting meat and leaves. But this was proven wrong.
The best example was the Paranthropus (傍人), one of our close cousins, some of which lived in eastern Africa. Scientists used to believe Paranthropus ate nuts and seeds because they had big crests(突起)on their skulls, suggesting they had large chewing muscles and big teeth. If this had been true, their teeth should have been covered with pits like the surface of the moon. They would also have had a particular type of carbon on their teeth that typically comes from tree products, such as nuts and seeds.
However, when the two scientists studied the Paranthroupus, it turned out to have none of these characteristics. The teeth had a different kind of carbon, and were covered with scratches, not pits. This suggests they probably ate grass, not nuts and fruit stones. It was the exact opposite of what people had expected to find.
Carbon “foodprints” give us a completely new and different insight into what different species ate and the different environments they lived in. If a certain species had the kind of carbon on its teeth that came from grasses, it probably lived in a tropical grassland, for example.
1.The underlined sentence in Paragraph 1 probably means that _____.
A. anthropologists can study the structure of human stomachs by studying their teeth.
B. anthropologists can study the diet of early humans by studying their teeth
C. anthropologists can learn whether humans were healthy by looking at their teeth
D. anthropologists can get the most useful information about humans from their teeth
2.According to Paragraph 3 to 5, which of the following statements is TRUE?
A. Scratches on teeth are caused by eating nuts or seeds.
B. Pits on teeth are caused by eating grass or leaves.
C. Early humans with hard and sharp teeth ate meat and leaves.
D. Different foods leave different marks and carbon on teeth.
3.The example of the Paranthropus was mentioned in the article in order to _____.
A. tell readers that they are one of our close cousins living in eastern Africa
B. tell readers they had different eating habits from modern humans
C. prove that size and shape of skulls does not show accurately what early humans ate
D. tell readers that living environment makes a difference to skull structure

People are different. Some are extrovert. These people are outgoing, confident, and know the “gift of the gab”. They also feel very comfortable when in groups of people.
Unfortunately we have the other extreme. This is the introvert. The introvert feels sick in crowds, and does not like them. These people feel awkward in the crowds, when placed in this type of situation. Many introverts are shy and lack confidence. They need to get used to people, and want to run away when questioned by people.
The introvert feels very lonely in a crowd, but this could happen to the outgoing as well.
I think that I fall into the middle of the two kinds. Sometimes if I am comfortable about the type of people in the crowds, I feel welcome. If for some reason the crowd consists of different types of people, then I do not feel very comfortable in the crowd.
So what do I do when I suddenly feel lost and alone in the crowd? I try to calm my mind by taking deep breath and telling myself that even this will pass. I then try, and get away from the crowd by making excuses or even trying to get to my car and go home. This, of course, is a poor excuse and doesn’t often work well. These are excuses that are employed. The ones that I am not so proud of are acting like I have an emergency to go to. This is a very good lie, but I feel really bad afterwards.
I have tried this one, and have succeeded. I try and find someone who feels just like I do. I then try and make a new friend. Sometimes this works and sometimes it does not. This is quite a noble way of staying in the crowd.

From my first day, I was attending press conferences and other media events all over town. I got to attend events at places I had never thought I’d get to: the White House, the Senate and House of Representative buildings at the Capitol (国会大厦), the Department of Health and Human Services, just to name a few. And I was sent to cover these events as if I were a reporter, not just an intern (实习生) .
In fact, I never really felt like an intern. I was given the opportunity to do the work that everyone else at the paper was doing. I covered stories on my own and wrote the articles myself. I was included in discussions for story ideas. I helped to edit the articles that went into the paper. I was able to take part in every aspect of the newspaper that I wanted to experience.
The best part of working at the Nation’s Health was the staff. They were supportive in letting me go out and do things on my own, while I always knew that they would be more than happy to answer any questions or help me with any problems I might have. Best of all, they treated me as their equal, not just an intern whom they could get to do all the work they didn’t want to do.
After interning at the Nation’s Health for nearly seven months and having more than 30 articles published, I had to move on. My experience there gave me insight into how the media work, which helps me when I’m trying to choose stories. In addition, it showed me that work really can be fun.
