句意：我们对2000名学生进行了一项关于他们最喜欢的电影的调查。喜欢科学电影的学生人数比喜欢纪录片的学生多200人。

考查数词计算，根据表格可知2000名学生中最喜欢科学电影的占30%，即2000 x 30%=600人；喜欢纪录片的占100%-20%-30%-（600/2000x100%）=20%，即2000x20%=400人，600-400=200，故选B。

【题目】 Your Internet experience will be influenced, when the net speed is too slow-it takes so long to open a web page and the reality show you are watching stops every few minutes. That can be very unpleasant. But it could be a thing of the past after 5G networks fully arrive.

The "G" stands for the "generation" of your mobile network. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data (数据) and the Internet, and 4G made all of these things faster. About 100 times faster than 4G networks, 5G will let people enjoy a faster Internet speed than ever before. This means that you will be able to download (下载) an HD movie in seconds with a short delay (延迟). But 5G won't just bring faster mobile Internet. People can use it for many other things as well.

With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid unexpected dangers. At the same time, 5G -enabled wearable devices (设备) will keep doctors know what is happening to their patients and let them know in time if there is something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

According to BBC, though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not travel "far". On 4G networks, you can be 10 kilometers away from the nearest transmission base (传输基站) and seldom lose signal (信号). But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products exactly made for 5G that are expensive now.

【1】After 5G is widely used, ________.

A.opening a web page and the reality show can become a past thing

B.the Internet speed will be faster when we surf the Internet

C.we won't have the unpleasant feelings anymore

【2】What can we infer from the Paragraph 2?

A.We cannot download an HD movie with 4G.

B.3G makes it possible for us to go shopping online.

C.Faster mobile Internet is the only improvement for 5G.

【3】What does the writer mean to do in Paragraph 3?

A.To give examples about the convenience brought by 5G.

B.To show different opinions from the possible 5G users.

C.To question the possibility of using 5G in daily life.

【4】According to BBC, ________.

A.you won't lose signals while using 5G

B.downloads of 5G overweight its upsides

C.5G can be used on certain mobile phones

【5】What is the best title of the passage?

A.5G Is Being Widely Used.

B.5G Will Make Life More Convenient.

C.5G -A Perfect Technology for Fun.

【题目】 If you have a pet like many people, you care for it as if it was your child. Meeting its needs and wants is an important part of your life, because you want it to be happy. However, there is one thing that it needs but cannot tell you about: that is music. There are a few reasons why your pet should listen to music.
