( )5. —How is our government going to deal with the office building?
—It will be ________ a library.
A. turned off B. turned on C. turned out D. turned into

答案： 5. D 【点拨】turn off 关掉；turn on 打开；turn out 结果是，证明是；turn...into...把……变成……。根据语境可知选 D。

( )6. How beautiful the landscape is! Why ________ you put down your phone and enjoy it?
A. can B. can’t C. must D. mustn’t

答案： 6. B 【点拨】can 能；can't 不能；must 必须；mustn't 禁止。根据语境可知，这里风景很美，可推测此处是询问为什么不能放下手机来享受美景。can't“不能”，符合语境。故选 B。

( )7. The Forbidden City(紫禁城), the largest palace in the world, ________ more than 600 years ago.
A. built B. were built C. was built D. was building

答案： 7. C 【点拨】主语和动词之间是动宾关系，且“more than 600 years ago”是一般过去时的标志，所以要用一般过去时的被动语态(be done)；主语是单数，be 动词用 was。故选 C。

( )8. —Have you ever been to the Great Wall?
—Sure. As an old saying goes, “________”.
A. Each dog has its day
B. The early bird catches the worm
C. He who has never been to the Great Wall is not a true man
D. Many hands make light work

答案： 8. C 【点拨】Each dog has its day 人人皆有得意日；The early bird catches the worm 早起的鸟儿有虫吃；He who has never been to the Great Wall is not a true man 不到长城非好汉；Many hands make light work 人多好办事。根据语境可知，此处应回答“不到长城非好汉”。故选 C。

五、热点素材 阅读理解。
It is widely known that China has the most advanced high - speed railway network in the world. Now, the country is breaking its own speed record with CR450.
CR450 can travel at 400 kilometres per hour on average, with a top speed hitting 453km/h. Before this, the fastest high - speed train operating in a rail network in the world is China’s CR400, which runs at 350km/h on average.
Once put into use, for example, the CR450 will shorten the travel time from Beijing to Shanghai to just about two and a half hours, which takes at least four and a half hours at the moment.
“The key is not to make the train run fast but to have it brake(刹车) accurately(精准地) and steadily(平稳地),” Zhao Hongwei, the China Academy of Railway Sciences told CCTV News. The standard is that the CR450 should have the same brake distance as the CR400, which is 6,500 metres, even though it travels a lot faster. It can also start braking more quickly, taking just 1.7 seconds compared to the 2.3 seconds needed for the CR400.
The engineers did lots of tests with the brakes to make the system better. In the tests, the brake disc(制动盘) got really hot, reaching temperatures of up to 700℃. Its colour changed from black to red. The changes were then recorded. All the data were saved in a smart system to make a digital model(数字模型) of the brake system for calculations(计算).
Apart from having a better braking system, the CR450 has the same noise level as the CR400. Moreover, it is 12 percent lighter and 20 percent less energy - consuming(耗能的), according to CCTV News. With all its advantages, people are getting excited about the train’s debut(首次亮相), which is planned to be within this year.
（ ）1. Compared to the CR400, the average speed of the CR450 increased by ________.
A. 50km/h B. 100km/h C. 350km/h D. 450km/h
（ ）2. According to Zhao Hongwei, what is “the key” to CR450?
A. Increasing the train’s speed.
B. Making it brake accurately and steadily.
C. Having shorter braking distance.
D. Starting to brake in a shorter time.
（ ）3. Compared to the CR400, the braking time of the CR450 ________.
A. is 0.6 seconds faster B. is 0.6 seconds slower
C. is the same D. is 1 second faster
（ ）4. What is Paragraph 5 mainly about?
A. How engineers cooled down the brake disc in a test.
B. What engineers did to improve the brake system.
C. How a digital model was used for calculations.
D. What differences the CR400 and CR450 have in their brake systems.

答案： 1. A 【点拨】根据第二段可知，CR450 的平均速度为 400 km/h，而 CR400 的平均速度为 350 km/h。因此，CR450 相比 CR400，平均速度提高了 400 km/h - 350 km/h = 50 km/h。故选 A。
2. B 【点拨】根据 Zhao Hongwei 对 CCTV News 的说法，CR450 的关键“不是让火车跑得快，而是要让它刹车准确和稳定”。
3. A 【点拨】根据“taking just 1.7 seconds compared to the 2.3 seconds needed for the CR400”可知，CR450 的刹车时间只需要 1.7 秒，而 CR400 需要 2.3 秒。所以 CR450 比 CR400 快了 2.3 秒 - 1.7 秒 = 0.6 秒。
4. B 【点拨】第五段主要讲述了工程师们如何通过测试和记录数据来改进刹车系统，以及如何使用智能系统创建刹车系统的数字模型进行计算。
