1 . 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.

4 . 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.

7 . 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。

In December 2018, a bunch of friends and I went to Europe to travel. Upon arrival in Vienna, we got the keys to the house from its owner. The     1     (decorate) of the house was quite good.

In Vienna, if anyone wants to copy a key, he or she is expected     2     (prove) their ownership of the property (房产) the key is for. It’s also really expensive. An ordinary key usually costs 150 euros (1.170 yuan). As the person in charge of the keys, I had a great responsibility.

    3     next day, we went everywhere, including the Sisi Museum and a coffee shop in the city center,     4     had dinner in a fancy restaurant. We felt quite relaxed. While we     5     (enjoy) dinner, my friends came up to me, asking for the keys so they could leave early. It was then that I realized that I’d lost them.

The host asked us to give him 300 euros to cover the cost of a new set of keys. We made a complaint about it but we had to pay the money. So, hoping to get our money back, we decided to do some detective work     6     our own.

I wrote an email to the Sisi Museum in the middle of the night, wondering whether the staff had found them. Early in the morning, I received their reply, saying that they had not.

    7     (fortunate) in the end, the keys were found in a souvenir shop. The host even said congratulations to us.

Though we saw many great     8     (sight) in Europe, the most     9     (value) thing about my trip was this lesson I learned: Never lose your keys in Vienna. Your keys ought to     10     (take) good care of.

I was _________ given a bicycle by my host family. _________ it is only an ordinary bike, I was still __________ and couldn’t wait to take a cycling trip alone.

One sunny Sunday afternoon, I took my first cycling trip to a village nearby. I cycled for a while, alongside a river. But then, something happened: One of my tires __________. There was no choice but to __________ my bike back home, which took an hour.

I didn’t give up though: One week later, I __________ again. This time, however, there was__________ wrong with my tires.

A Chinese military transport plane, escorted (护卫) by two Chinese fighter jets, carried the remains and belongings of the fallen soldiers back and landed at Taoxian International Airport at 11:18 am in the northeastern Chinese city of Shenyang near the border of the Democratic People’s Republic of Korea. Y-20 aircraft. the largest and most advanced domestically developed transport aircraft. carried out the task for the first time. It was labeled (贴标签于……) with the serial number 01. as a mark of high respect for the martyrs.

Many local residents lined the roads to welcome the martyrs home and show their respect.

The remains will be buried in a martyrs’ park in Shenyang on Monday. It is the resting place of all soldiers’ remains returned by the ROK since 2014.

This year marks the 70th anniversary of the CPV’S participation in the 1950-53 Korean War. A total of 2.9 million CPV soldiers entered the battlefield, and 197,653 of them were killed in the war.

10 . It might seem like something from a science fiction movie, but scientists today are working on ways to combine certain kinds of bacteria with tiny robots. Scientists want to use these creations to improve the way we give medical treatment. They claim that drug therapy (疗法), disease diagnosis, and even surgery could be greatly aided by the use of nanobiotechnology. Nano-means “tiny”, and bio-means “life”. This tiny technology will use living organisms in combination with electronics.

Electronics makers already use tiny robots to build complex but very tiny circuits. Medical scientists want to use these robots to repair patients’ damaged organs or to direct medicines to affect specific cells. For example, tiny robots could be engineered to deliver chemotherapy (化疗) directly to cancer instead of to the entire body.

Existing electronics are the right size, but they lack practical use. Robots that can be built small enough to enter a person’s cells would be too tiny to move on their own. Therefore, scientists want to use tiny organisms such as bacteria to act as vehicles for the robots. The bacteria will be “driven” through the bloodstream by magnetic pulses (磁脉冲). Once the bacteria are in the correct locations, the robots will be able to do their jobs. In theory, these robots will cause less damage to the body than traditional methods of delivering medicines or performing surgeries.

Nanobiotechnology has yet to be put into practice, but many people already have concerns about its use. Some people worry about the ethic (道德标准) involved with controlling live organisms—and the possible side effects for their human hosts.

1. What does the second paragraph mainly talk about?

A．The application of tiny robots.	B．The influence of tiny robots.
C．The operation of tiny robots.	D．The origin of tiny robots.

2. Which of the following could be a future benefit of nanobiotechnology?

A．Cheaper medicine.	B．Less harm to the body.
C．Longer life expectancy.	D．Faster performance of surgeries.

3. According to the medical scientists, robots ______.

A．can locate he bacteria.	B．are driven by medicine.
C．can act as vehicles.	D．are carried by bacteria.

4. Where does the text probably come from?

A．A computer textbok	B．A life magazine
C．A science magazine	D．A biology textbook
