【題目】In one way, it is the “greatest” drone ever. In another, though, it is the opposite of what a drone should be. Drone should be very lazy. They don’t have to work. Only their sister should be busy pollinating (傳授花粉) and producing honey. However, for this drone, pollination is the very reason fur its existence (存在).

The drone, in fact is an invention of Ejiro Miyako. Miyako is a scientist from Japan. Many people, including Miyako have been worried about the future of food industry. Pollinating insects, especially bees, are falling in number. As a result, some plants can’t get pollinated and there will be fewer plants for us to eat. Scientists have been working hard to increase the number of bees. Unfortunately, they have had little success. Perhaps, Miyako thinks, it is time to build some robot bees instead.

Miyako’s bee, in fact, does not look much like a bee. It is based on a quad-copter. Miyako has put some brush hair on it. The hair is covered in special glue. They are able to pick up and hold grains of pollen(花粉) until they brush up against something else.

At the moment, Miyako’s robot bee still needs help from human operators. That’s because it can’t see where its target (目標(biāo)) are. In the next step, Miyako will install visual recognition (視覺(jué)識(shí)別) software on his bee. After that, the robot bee will be able to see by itself.

【1】In the first paragraph, the underlined “drone” refers to a kind of ________.

A. flowerB. beeC. honeyD. software

【2】Ejiro Miyako is worried that ________ in the future.

A. we may be short of food

B. natural bees may not produce honey

C. his robot bee can’t see

D. natural drones can’t pollinate plants

【3】Ejiro Miyako’s invention is used to ________.

A. produce honeyB. watch natural bees work

C. pollinate plantsD. increase the number of natural bees

【4】Which of the following is a must for Ejiro Miyako’s invention?

A. Pollen.B. Drones and their sisters.

C. Brush hair.D. Visual recognition software.

【5】According to the article, what will Ejiro Miyako do in the next step?

A. Produce more robot bees.

B. Fill his garden with robot bees.

C. Allow robots to pick up pollen.

D. Make his robot bees work independently.

科目：初中英語(yǔ) 來(lái)源： 題型：

【題目】The Vieira family moved to the United States in 1981.At that time, they decided to stop speaking Spanish at home and only communicate in English. This was because they were now living in an English-speaking country.

Now the Vieira children are adults, and they sometimes travel to Spain to visit their family and friends. But they can't communicate with them. Unfortunately this is common. When people move to new countries, they often leave their own customs and mother language behind. This is a mistake because there are many benefits to knowing more than one language.

One advantage of speaking more than one language is that you can communicate with more people around the world. You don't have to depend on others to talk for you, so you are more independent. People who know only one language must use others to help them communicate.

Furthermore, speaking the second language also allows people to experience other cultures and customs more effectively .Local expressions, vocabulary, and even jokes can have a powerful effect on a person's understanding of other culture. So knowing more than one language increases your knowledge of other cultures.

Finally, having more multilanguage speakers improves relationships between countries. If people from different countries can communicate well, the world can become closer. Countries will then have more respect for each other and better understand each other's problems.

The benefits of knowing more than one language are clear. In fact, there are no disadvantages. It is very sad that many people don't try to learn another language. It's even worse when people let themselves forget their mother language and become silenced.

【1】The passage begins with the experience of Vieira family in order to ________.

A. discuss the need of teaching a new language

B. introduce the passage's main characters to the readers

C. describe the advantages of moving to another country

D. show the problem of speaking only one language

【2】The underlined phrase “multilanguage speakers” (paragraph 5) means “people who know ________.”

A. their mother languageB. a new language

C. more than one languageD. baby language

【3】According to the passage, if you can speak more than one language, you can ________

A. find a better jobB. make more friends

C. better understand historyD. communicate more independently

【4】Based on the last paragraph, which of the following is the worst?

A. Not knowing another language.B. Forgetting one's language.

C. Refusing to learn another language.D. Failing to communicate with others.

科目：初中英語(yǔ) 來(lái)源： 題型：

【題目】 Mukbang, a South Korean word, means “eating broadcast(吃播)”. It is an online broadcast in which a host eats tons of food while talking with the people watching him or her. It began in South Korea in around 2010 and has spread all over the world.

Why did mukbang first appear in South Korea? Jeff Yang, an Asian-American cultural critic(評(píng)論家), thinks that it’s down to “the loneliness of unmarried or uncoupled South Koreans”. He believes that eating on your own can be hard in a country like South Korea, where social eating is such a long tradition. However, eating alone is becoming increasingly common. It seems that mukbang gives people the feeling that they are part of something larger.

Alice Stride, a spokeswoman for the Campaign to End Loneliness, says, “It might bring someone great comfort to watch mukbang.” She adds that she would be worried if younger people were watching people eat instead of eating with friends or family, but for older people it could be a comfort. “If you can’t get out, if you’re ill for example, then perhaps that will bring you a great sense of comfort. On the whole, though, we would advocate face-to-face communication. It’s something that won’t change.”

“I would always encourage people to do whatever makes them feel better as long as it is a healthy habit,” says Ben Edwards, a relationship expert. “I doubt if mukbang is a healthy way to have a meal. But I think if people feel like watching other people eat, and it gives them some sort of satisfaction, I see no harm.”

【1】What questions are answered in Paragraph 1?

①How old is mukbang?

②What does mukbang mean?

③Where did mukbang begin?

④How did mukbang get popular?

A. ①②③B. ①③④C. ①②④D. ②③④

【2】According to Jeff Yang, it is difficult for South Koreans to eat alone because they_____________.

A. have the culture of eating togetherB. are supporters of ending loneliness

C. like joining a larger groupD. usually have a big family

【3】Which of the following is probably Alice Stride’s opinion?

A. Mukbang helps lots of people feel less lonely.

B. Older people are more interested in mukbang.

C. Younger people should offer more comfort to older people.

D. Younger people should eat with their friends and family a lot.

【4】What does the underlined word “advocate” in Paragraph 3 probably mean in Chinese?

A. 觀察B. 提倡C. 建立D. 評(píng)估

【5】What does Ben Edwards think of mukbang?

A. It is difficult to do.B. It is healthy for the host.

C. It is an acceptable thing.D. It is a popular way of eating.
