One of the most famous scientists to study adaptations(适应能力) was Charles Darwin(达尔文). He was born in England in 1809. He wasn’t the best student in his school, but when he was 16, his father sent him to a medical school. Charles liked spending time outdoors observing(观察) nature more than having medical classes. He dropped out without graduating.
Next, Charles’ father sent him to school to become a minister(牧师). This time he made it to graduation, but he didn’t want to do the work of a minister. His friends encouraged him to follow his interest in science.
Luckily, Charles was invited to sail on the Beagle as an unpaid scientist after graduation. The Beagle was to travel to South America and then around the world. Their task was to make maps of the places they visited.
On December 27th, 1831. Charles Darwin sailed from England on the Beagle. The trip was planned to last two years. In fact, it lasted five. During this time, he saw many amazing things. He collected lots of plants and animals and took them back to England to begin his scientific study.
Twenty-three years later, Darwin published a scientific paper with another man named Wallace. Darwin described how some animals have adaptations that help them survive. They are passed on to offspring(后代). Darwin’s ideas about adaptations are still very important to the study of living things.

阅读下面材料，从每题所给的三个选项（A、B和C）中，选出最佳选项。

What should you take in with you when you take an exam? Pen, pencil, eraser, ruler … and don’t forget a bottle of water!

According to a study held in London, students who bring water into exams may improve their grades by up to 10%.

Scientists in UK did the study on 448 students. The students were studying for different degrees  at the University of East London. Only 25% of them entered the exam hall with water.

Scientists then compared their exam results with their normal schoolwork grades. They found that all those who had brought water with them got better grades by 2% to10%.

Scientists also predicted the students’ scores according to their normal schoolwork. They wrote down their possible scores on paper before exams.

It is unclear why drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a helpful effect on our brains. Drinking water may also reduce anxiety (焦虑), which has a bad effect on exam performances.

“Whatever the explanation is, it is clear that students should try hard to stay hydrated (含水的) with water during exams,” one of the scientists said.

So next time, when you are going to have a big exam, try bringing a bottle of water with you. It may help you pass the exam!

In life, people come across many experiences, which they remember all their lives. I had a similar experience, too.
It was the day of my last paper of the final exam. My uncle had invited me to spend my vacation with him. I was especially excited about the invitation that my uncle had given me to stay with him for a few days in Cambridge.
On that day we got into our classroom. The teacher quickly handed out the paper. The exam would last two hours and some of the expected questions came. I finished it almost forty-five minutes earlier. But since it was a rule not to collect the paper before the allotted（规定的）time. I had to sit till the teacher collected the paper. I checked my paper twice and corrected some of the mistakes in it. I started thinking about the place my friends and I had planned to go to after the exam. The time seemed to be endless. So I thought of drawing something on the paper and turned it overleaf. I was shocked to see that the page which I had supposed to be blank had four more questions on it which carried 20 marks and would take at least half an hour to complete. There were only 10 minutes left. I was so nervous that I could hardly write anything. They were the sub-questions（小题）of the last question. Suddenly our physics teacher came in and told all of us that in the last question, out of 6 sub-questions only 2 had to be solved. I felt very relieved.
From then on, I realized that my anxiousness and excitement could have cost me to lose 20 marks and decided never to make such a mistake again.
