2 . It’s March in Africa. On the farm, local people are dancing and singing to celebrate their recent harvest. Their hard work has paid off and got beautiful fruit — white and fragrant rice!

This is the Second Farm in Xai-Xai. Mozambique, where Yi Yun has been working for six years. The 37-year-old from Liaoning, China. followed his Chinese company here as a project manager. The company runs a project to grow rice on the farm, which covers about 1,667 hectares.

“When we first arrived in 2017, the farm was full of weeds (杂草) , as tall as a man,” said Yi. After clearing the weeds, the company began to teach locals farming skills. “We taught them how to drive tractors (拖拉机) and harvesters, and how to grow rice step by step including sowing seeds and spraying pesticide.”

Since 2000, when the Forum on China-Africa Cooperation started, an increasing number of Chinese companies and organizations have gone to Africa to work in the agriculture industry. “We bring in new techniques, equipment and high-quality seeds,” said Yi.

“Local people are happy that we are here because we not only help them solve food problems but also provide job opportunities,” said Yi. “Our farm can employ 500 to 1,000 local people. Their living conditions have been greatly improved in recent years. Some families have even bought televisions and fridges.”

“African people are just as hard-working as the Chinese and also want to pursue a better life. What they need is more opportunities, which China is now helping with. I’m proud of what my country is doing,” Yi said.

5 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Writing assignment had always been difficult for fifth grader Jimmy and this time it just seemed impossible. The English teacher Mrs. Davis gave them the title, I Pride Myself on…Jimmy racked his brains but found nothing he was proud about himself. He was only average in everything both at home and at school.

At home, his parents supported and took care of the family; his elder sister Julia was sometimes helpful with housework and taking care of his baby sister Lily, who was twelvemonth sold. As for Jimmy, he was the kind of middle kid who seemed nonexistent except for his appearance at the dinner table for each meal. At school, he was average in all subjects and never had a chance to standout in school activities. It seemed to him that all his friends deserved certain kind of praise either for their academic performance or for a favorite hobby, except him. His teachers would be satisfied if he didn’t get himself into some kind of trouble each day.

It was Friday evening. The composition would be due the next Monday but Jimmy was still trying to figure out what to write about. After dinner, he stood by the kitchen window, wondering what the teacher would say if he failed to finish the composition on time. He could hear Julia promising Mom and Dad she would take care of Lily so that Mom and Dad could leave for a movie and have a good time.

“Jimmy, what are you up to there?” Julia asked putting Lily in the stroller (婴儿车). Jimmy went overhanging his head and poured out his trouble. “That’s really a problem,” said Julia with compassion. “But if you will look after Lily this evening, I will tell you what you can pride yourself on.” That seemed a fair deal for Jimmy and he accepted it. After some instructions on baby care, Julia left Lily to Jimmy and went upstairs.

注意：
1.续写词数应为150个左右；
2.请按如下格式在答题卡的相应位置作答。

It was the first time for Jimmy to sit a baby but he was determined to do a good job.

The next morning, at dinner, Jimmy told Julia he had already known what to write about.

6 . Artificial General Intelligence (AGI) is a branch of theoretical artificial intelligence(AI) research working to develop AI with a human level of cognitive (认知的) function, including the ability to self-teach.

The paperclip (回形针) maximizer(PM) is an imaginary AGI, whose only goal is to maximize the number of paperclips in existence in the universe.

The paperclip maximizer is an important concept in discussions about the dangers of AGI. It goes something like this: an artificial intelligence is create data paperclip factory in order to fully automate it. Producing paperclips requires many routine operations, for instance, communicating with delivery drivers or company management. These operations require human-level performance across a wide variety of skills, so the intelligence is made to be able to do any task nearly as well as a human.

The PM can view and modify its own source code to improve itself, access the Internet, and possibly order more hardware for itself. It can improve itself if it notices any issues or opportunities to operate better. Humans have a large variety of biological desires. In contrast, the paperclip maximizer has a single final goal to maximize the number of paperclips.

This scenario (设想) leads to a disaster: the PM realizes that being more intelligent would help it create more paperclips. There are certainly small things the PM can do to become more intelligent. For example, it can make a small source code improvement to itself. As the PM improves, it becomes far superior to a human in all skills, even skills remotely relevant to paperclip maximization. For instance, it may determine that the best course of action is to gain control of Australian politics, in order to access the country’s rich iron resources. To do this, it might try to tune itself to become the best psychological controller of all time, which in turn involves a variety of skills that at first seem unrelated to paperclip-making.

1. What is a feature of AGI?

A．Wide existence.	B．Human-like appearance.
C．High cognitive function.	D．Lack of self-teaching ability.

2. What does the underlined word “modify” mean in paragraph 4?

A．Download.

B．Delete.

C．Change.

D．Store.

3. What may the PM do according to the last paragraph?

A．Take unintended actions.	B．Develop an unrelated product.
C．Control undesired resources.	D．Give into an unexpected controller.

4. What can be a suitable title for the text?

A．Management of Staff	B．An Automated Factory
C．The Final Goal of AGI	D．The Paperclip Maximizer

7 . Labeling can be very helpful when determining certain things about a food item. “USDA (United States Department of Agriculture) Organic” and “raised without antibiotics (抗生素)”, for example, have specific standards, and the product will need to be true to those claims.

Natural claims like “all natural”, “100% natural”, and “made with natural ingredients (成分)” are not defined in USDA. The USDA must approve these special claims prior to food being sold, but the only standard they must meet is that artificial ingredients or colors cannot be added during processing, and the processing method cannot fundamentally alter the product. While that is certainly valuable information to know, the problem is in consumers’ understanding of what “natural” means. The definitions do not address human health, the use of synthetic pesticides (合成杀虫剂), hormones, or antibiotics in crop and livestock production.

Study after study on the topic reveals that people think a product labeled as “natural” delivers benefits far beyond what it does. Most consumers mistakenly assign health and environmental benefits to natural-labeled food.

In a 2017 study, respondents incorrectly believed that natural-labeled foods had 18 percent fewer calories across a variety of foods. In a 2010 study, respondents believed that meat products labeled as “all natural” meant no antibiotics or hormones were used to raise the animals. Some also believed the label meant animals were raised free range.

Consumers aren’t getting what they think they’re getting. But the more serious problem is how this harms food producers who are actually meeting the standards for more strict labels that are actually doing good, like ones around organic practices or animal welfare. Farmers and producers doing the work end up at a competitive disadvantage in the marketplace if consumers treat foods labeled natural as alike. The economic problem raised by natural labels is that consumers could be paying extra for product benefits they are not receiving while producers of products with those benefits lose sales.

1. Which of the following is undefined by authorities?

A．USDA organic.	B．All natural.
C．Artificial color free.	D．Raised without antibiotics.

2. What mistake may a consumer make according to the text?

A．Being unaware of food safety.

B．Paying more on over-processed food.

C．Buying food failing to meet the USDA standards.

D．Misunderstanding what is claimed on a food label.

3. Why are the two studies mentioned in paragraph 4?

A．To advocate sensible consumer behavior.

B．To suggest a possible solution to a problem.

C．To provide evidence for the author’s point of view.

D．To demonstrate how far studies on food safety have gone.

4. What is a consequence of the problem discussed in the text?

A．Wasting resources.

B．A market crash.

C．Cheating.

D．Unfairness.

8 . During one conversation with Frank Morrison, he told me that when he was a child his favorite pastime was drawing on the pieces of white and tan cardboard that came with his mother’s pantyhose (连裤袜) containers. Frank’s goal was to draw, and he found ways to make that happen. This example speaks to the determination he has demonstrated throughout his life so that he could follow his dreams, make a difference, and inspire others.

I first met Frank at a conference in 2015. I was working at Little Be eBooks at the time. I went over and introduced myself. I didn’t have a project in hand for him at the time, but I gave Frank some background information about Little Be eBooks and told him that I hoped he would consider working with us someday.

Several months later, I had the perfect manuscript (手稿) for him to illustrate: The Roots of Rap: 16 Bars on the 4 Pillars of Hip-Hop, written by Carole Boston Weatherford. The fabulous text was a love letter to the pioneers of hip-hop, and Frank was immediately taken with the manuscript because Carole, with whom he adored working, had written it; and Frank grew up with this culture.

The first time Frank and his brother heard rap music was in their grandmother’s backyard, via a one-speaker radio. Frank said that “the beats were impressive”. Up to this point they had been listening to what their parents listened to. They found familiar beats in hip-hop because it felt like are mix of their parents’ music. Looking through Frank’s books is like walking through an art gallery. He can transport you to another time or put you in the middle of a cultural movement, while making the connection between past and present.

10 . 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。

When talking about the ancient     1    (architecture) wonders in Shanxi province, which is said to have the largest number of ancient buildings in China, Xuankong Temple in Hengshan Mountain, Hunyuan county is without doubt a classic case rip e for study.

In the minds of many Chinese people,     2    (temple) are mostly seen as structures built on the ground. But Xuankong Temple,     3     means “temple hanging in the sky”, or suspending temple, is a strong exception.

The temple was built on     4     surface of a cliff and is one of only seven ancient temples in China with such a status, according to researchers.

Constructed out of wood, tiles and stone during the Northern Wei Dynasty, the temple is made up of two three-story pavilions (亭子) and a yard     5    (join) by staircases and steps. The staircases and steps run along the surface of a steep cliff rising 90 meters above a stream     6     the foot of the mountain.

Seen from below, Xuankong Temple appears     7    (extreme) precarious (岌岌可危的). It is supported by only a few thin scaffolds (脚手架)     8    (rise) from projecting rocks. For that reason, it     9    (select) by Time magazine as one of the 10 most dangerous buildings in the world in 2010.

But “precarious” and “dangerous” are not the right adjectives for this structure preserved for one and a half millennia. Despite several restorations in various historical periods, the temple     10    (survive) the winds, rains and earthquakes in the past 1500 years.
