Professor Sun Jun, aged 93 in 2018, has devoted his life to working on China’s giant construction projects, including the Qinghai-Tibet highway, Three Gorges Dam, and the Yangtze River Tunnel. In his latest project, the Tongji University academic served as a senior adviser on the construction of the Hong Kong-Zhuhai-Macao Bridge.

Under the guidance of Sun, Xu Wei, a professor in Tonji and Sun’s student, took over technical assistance for the construction of the bridge. “Every time I saw Sun and other professors working on the bridge,I felt at ease,” said Lin Ming, the general project manager. Lin initially invited an experienced Dutch company to serve as the technical assistant for the project. The company wanted to charge US $171million. He then asked for help from Xu along with experts in Tongji University.

The methods developed by Tongji University reduced the impact of the bridge on the Chinese white dolphin, which is under first class state protection. The key challenge during the construction of the bridge was the 6.7-km underwater tunnel, the world’s longest and deepest undersea tunnel. Ding Wenqi, who was nicknamed the “ tunnel expert” , was asked to ensure the tubes be connected perfectly—even under the influences of land subsidence (下沉), water pressure and tide movement. Hu Xiangdong, another professor with Tongji, developed a method to freeze the earth around the tunnel to prevent water leakage and land subsidence during the digging of the most challenging 2-km section of the tunnel.

The tunnel section of the project was completed in May 2017. Sun was invited to visit the near-completed bridge again in February 2018. The expert said he felt the most relaxed this time since most of the challenges have been conquered. “In the next step, we should focus on how to make the two artificial islands more beautiful and attract travelers,” Sun said.

Xu said all the staff in my office took a great pride in watching the TV news of the bridge’s official opening on Wednesday.

1.What is Professor Sun’s contribution to the bridge?

A. He worked in Tongji University.

B. He was the general project manager.

C. He gave much advice on the project.

D. He took over the technical assistance.

2.Why did Lin Ming ask for help from experts in Tongji University?

A. The Dutch company charged too much.

B. The technical assistant had too much trouble.

C. Tongji University did best in the giant projects.

D. He felt relaxed to see professors working on the bridge.

3.What’s the greatest trouble in building the bridge?

A. Protecting the Chinese white dolphin.

B. Constructing the longest & deepest undersea tunnel.

C. Controlling the water pressure.

D. Preventing the tide.

4.How did the expert stop water leaking in building the undersea tunnel?

A. By keeping the tide moving.

B. By digging deep into the sea.

C. By increasing the water pressure.

D. By freezing the nearby earth around the tunnel.

高三英语单项填空简单题查看答案及解析

Taste is such a subjective matter that we don’t usually conduct preference tests for food. The most you can say about anyone’s preference is that it’s one person’s opinion. But because the two big cola companies—Coca-Cola and Pepsi Cola are marketed so aggressively, we’ve wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting.

We invited staff volunteers who had a strong liking for either Coca-Cola Classic (传统型) or Pepsi, Diet (低糖的) Coke, or Diet Pepsi. These were people who thought they’d have no trouble telling their brand from the other brand.

We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants’ choices with what mere guess-work could have accomplished.

Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse----only 7 of 27 identified all four samples correctly.

While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so tiredness, or taste burnout, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.

1.According to the passage the preference test was conducted in order to ________.

A. show that a person’s opinion about taste is mere guess-work

B. compare the ability of the participants in choosing their drinks

C. find out the role taste preference plays in a person’s drinking

D. reveal which cola is more to the liking of the drinkers

2. It is implied but not stated in the first paragraph that ________.

A. the competition between the two colas is very strong

B. blind tasting is necessary for identifying fans

C. the purpose of taste tests is to promote the sale of colas

D. the improvement of quality is the chief concern of the two cola companies

3.The word “burnout” (Line3, Para. 5) refers to the state of _________.

A. being seriously burnt in the skin

B. being badly damaged by fire

C. being unable to function because of excessive use

D. being unable to burn for lack of fuel

4.The author’s purpose in writing this passage is to ________.

A. emphasize that taste and price are closely related to each other

B. recommend that blind tasting be introduced in the quality control of colas

C. show that taste preference is highly subjective

D. argue that taste testing is an important marketing strategy
