2 . When water is cold, people will find it uncomfortable to swim. Wetsuits(潜水服）can help keep people warm.    1    So wetsuits are important. In many water sports, you can find people wearing them.

The wetsuit doesn't have a long history. According to studies, the wetsuit only began during WWII when Italians started wearing wetsuits that were made of rubber. And it was widely believed in 1951, Hugh Bradner began working to improve the equipment.     2    

Now there are many kinds of wetsuits. Contrary to what some may think, wetsuits do not work by keeping the diver(潜水员）dry; they are designed to let water into the suit. This thin layer of water is trapped（保存）between the diver and the suit. And it's allowed to move between the skin of the diver and the inside layer.     3    And it can help keep the diver comfortable during the diving process. That's why it's important to have a nice, tight fit for a wetsuit.

    4    The shorter wetsuit often provides cover for the main part of people's bodies. This kind of wetsuit works well with boating, water skiing, swimming, etc. A longer wetsuit can completely cover the body, including long legs.With more protection for the body, it may be used in cool weather conditions.

Wetsuits can also differ in thickness. They range from about 0. 5mm to 8mm in thickness. It's true that thicker wetsuits are more likely to affect your movement.     5    Generally, the colder the water you plan to dive in, the thicker the wetsuit should be.

A．But they're much better at giving you warmth.

B．As for the difference, wetsuits can differ in size.

C．The history of the wetsuit is an interesting story.

D．This led to the development of a kind of new wetsuit.

E．Many wetsuits are very light and easy to wear and take off.

F．As a result, the water gradually warms up to body temperature.

G．And they can provide protection from the sun and cuts from rocks.

5 . 语法填空

Will you eat everything in your lunch box today? If not, will you save it for another time or just throw it away?

A recent study     1     (find) that 17% of all the food     2     (produce) around the world gets wasted each year,     3     reaches about 931 million tons. Believe it     4     not, 61% of the waste happens in our houses!

Food waste in homes     5     (happen) in rich countries like the US and the UK as well as in poor countries for different reasons.

Cultural habits could also lead to waste at home,       6     (include) massive packaging and “buy one, get one free” deals. ‘Use by’ or ‘best by’ dates       7     products could also cause people to throw away food. People could throw out food because they think it is     8     (safe) to eat, when in fact the date only shows when quality might go down.

Food was     9     (much) valued even in richer countries just a few generations ago, because people often couldn’t afford to waste it.     10     (throw) away food is for sure a great waste and we should try to make people know the importance of saving food.

6 . 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。

Lots of foreigners don’t understand why so many Chinese people are sorrowful about Yuan Longping’s passing away.

This reminds me     1     an issue more than 20 years ago,     2     I was a Chinese journalist in the US. Some American scholars     3     (think) China could hardly realize food-sufficiency because of the     4     (limit) water resources, decrease of agricultural land due to industrial     5     (expand) and the fast population growth. Just at that time, Yuan Longping announced breakthroughs in planting the new rice.     6     (bring) to large area application, this technique improved the annual growth of rice greatly, which fed     7     population of 60 million--equal to the whole of the UK.

Western scholars’ prediction of China back then was indeed analyzing China’s problems, but they failed     8     (realize) that the Chinese people have the capability to deal with these challenges.

If they had had any knowledge of Yuan who worked devotedly for our country, they wouldn’t have made such pessimistic evaluations. Why did the Chinese people make     9    ? Why are so many predictions about China in the West     10    (accurate)? It’s time to change minds to better understand China.

8 . 阅读下面材料，在空白处填入适当的内容（一个词）或括号内单词的正确形式.

Charles Darwin was an English     1     (science) who studied nature. He is known     2     his theory of evolution (进化论)．

Darwin was born on February 12, 1809, in Shropshire, England. In 1831, Darwin boarded a ship     3     (call) the HMS Beagle and set out on a fantastic five­year journey around the world. His goal was     4     (study) the natural history of the areas he was to explore. Darwin was     5     (amaze) at the variety (多样性) of species he saw on his journey. He noticed that although the different islands had similar animals and plants, many seemed to have changed to adapt (适应) to their local environments. He noted some     6     (difference) between the mockingbirds found on San Cristobal, Floreana and two other islands. This led     7     (he) to wonder why they varied from place to place.

Darwin first presented his theory of evolution by natural selection (选择) in 1858 to explain how animals adapted to their environment to survive. The idea of evolution     8     (be) not new then, but Darwin’s theory explained how evolution occurred. When Darwin published On the Origin of Species in 1859, the book was     9     immediate success. However, it was not popular with people     10     believed that all the animals on the planet had been made at the same time by one creator. But Darwin scientifically proved all the species on Earth had evolved from earlier species!
