The scale of consumers of fast food delivery service in China

The fast food delivery service, which depends on the already-existing restaurants, can cover a larger place with more customers without taking the seats of restaurants. Under the current economic and market condition, the fast food delivery service has been the new battlefield of the fast food giants in China. Even MacDonald’s and KFC, the two international fast food giants are fighting against each other for more market share in China’s fast food delivery industry.

However, Jing Linbo, Deputy Director of the Institute of Finance and Trade Economics, the Chinese Academy of Social Science, thought that the fast food delivery is the new growth point of fast food enterprises. But the fast food enterprises should have certain comprehensive strengths to do this service, which is thought to be different from the traditional food industry in some aspects.

Besides, with the development of the new industry, there also emerge problems. And some observers have given their warnings. They warn that if the fast food enterprises take no notice of the hidden problems, they will lose the customers in the competitive market gradually.

【题目】

News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.

Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?

To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.

Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them Into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs

Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.

【1】What does the underlined word "reluctant "in the first paragraph mean?

A. Delighted.B. Unwilling.C. Confused.D. Optimistic.

【2】What can we infer about previous news robots?

A. They read news without expressions.B. They looked like a human being

C. They could interview sports starsD. They could interact with audience.

【3】What do we know about the third technology?

A. This technology is very perfect so far

B. This technology is quite popular now

C. This technology remains at the theoretical stage

D. This technology is far from mature.

【4】From the last paragraph, we can draw a conclusion that____.

A. human news anchors should learn from AT anchors to save their jobs

B. Al anchors perform much better than human news anchors at present

C. Al news anchors won 't replace human news anchors in the near future

D. Xin Xiaomeng s expressions vary so naturally that they are true to life

【题目】 The okapi is a mammal living above the equator in one of the most biodiverse areas in central Africa. The animal was unknown to the western world until the beginning of the 20th century, and is often described as half-zebra, half-giraffe, as if it were a mixed-breed creature from a Greek legend. Yes its image is prevalent in the Democratic Republic of Congo-the only country in the world where it is found living in the world. The okapi is to Congo what the giant panda is to China or the kangaroo to Australia.

Although the okapi has striped markings resembling those of zebras’, it is most closely related to the giraffe. It has a long neck, and large, flexible ears. The face and throat are greyish white. The coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs and white ankles. Overall, the okapi can be easily distinguished form its nearest relative. It is much smaller (about the size of a horse) and shares more external similarities with the deer than with the giraffe. While both sexes possess horns in the giraffe, only males bear horns in the okapi.

The West got its first whiff of the okapi in 1890 when Welsh Journalist Henry Morton Stanley had puzzled over a strange “African donkey” in his book. Other Europeans in Africa had also heard of an animal that they came to call the “African unicorn.” Explorers may have seen the fleeting view of the striped backside as the animal fled through the bushes, leading to speculation that the okapi was some sort of rainforest zebra. Some even believed that the okapi was a new species of zebra. It was only later, when okapi skeleton was analyzed, that naturalists realized they had a giraffe on their hands.

In 1987, the Okapi Wildlife Reserve was established in eastern Congo to protect this rare mammal. But decades of political turbulence has seen much of the Congo’s natural resources spin out of the government’s control, and okapi numbers have fallen by 50 percent since 1995. Today, only 10,000 remain.

【1】Which of the following is a picture of an okapi?

A.B.
