【題目】 It has been a year since 1 first saw UBTech's Walker robot at CES 2019. I was blown away by its ability to perform many tasks.

A year later, it had come a long way, gaining much better motor skills and the ability to maintain balance. During a CES 2020 demo(演示), UBTech showed how far Walker had come.The robot walked over to a table, picked up a bottle opener and used it to remove the cap from a bottle of soda. It picked up the bottle and a glass and poured the liquid in, without spilling.During the demo, Walker also performed a number of serious Yoga( 瑜伽) poses, including standing on one foot and leaning back.

UBTech said that the ability to pour drinks required visual servo( 伺服系統(tǒng)) technology using its cameras to judge the position of objects. The same methods allowed Walker to uncap a marker and draw a picture of a flower on a piece of paper at another point in the demo.

All of the betterment was made via software as UBTech hasn't made any physical adjustments t0o the robot since we saw it last year. On the inside, the robot uses a combination of a few different operating systems on these internal PCs, including Ubuntu, ROS and Android. Its battery promises up to 2 hours battery life after a 2-hour charge time,

UBTech continues development on this pioneering robot, but doesn't have public launch date. The company is targeting Walker toward the home, with an emphasis on helping seniors or. just doing house cleaning. To make it stable enough to adapt to all these different conditions is a huge challenge. However, if development of Walker continues, this robot could eventually be a game-changer.

【1】How did the author feel when first seeing the robot?

A.Amazed.B.Proud.

C.Awkward.D.Disappointed.

【2】What is Paragraph 2 mainly about?

A.The demos of CES 2019.B.The improvements of the robot.

C.The robot's motor ability.D.The robot's ability to remain steady.

【3】What enables the robot to draw pictures?

A.The cap of the marker.B.The ability to pour drinks.

C.The using of more cameras.D.The system of position judging.

【4】What can we infer from the last paragraph?

A.The robot is stable enough to help the old.

B.The robot has been available to the public.

C.Our life could be greatly influenced by the robot.

D.The basic concept of robot making will be changed.

【答案】

【1】A

【2】B

【3】D

【4】C

【解析】

本文是說明文。文章介紹了UBTech公司開發(fā)的Walker機(jī)器人，它具備執(zhí)行許多任務(wù)的能力。Walker的繼續(xù)發(fā)展可能會(huì)讓我們的生活更加便利。

【1】

細(xì)節(jié)理解題。根據(jù)第一段中的“I was blown away by its ability to perform many tasks.”可知，我對(duì)它執(zhí)行許多任務(wù)的能力感到震驚。即作者在初次見到這個(gè)機(jī)器人時(shí)感到很驚訝。故選A。

【2】

段落大意題。根據(jù)第二段可知，一年后它獲得了更好的運(yùn)動(dòng)技能和保持平衡的能力。它走到桌子旁，拿起開瓶器，用它從一瓶蘇打水上取下了瓶蓋。它拿起瓶子和杯子，倒入液體時(shí)沒有溢出。在演示過程中，Walker還進(jìn)行了許多瑜伽姿勢(shì)，包括單腳站立和向后傾斜。即第2段的主要內(nèi)容是隨著時(shí)間的推移，機(jī)器人功能的改進(jìn)。故選B。

【3】

細(xì)節(jié)理解題。根據(jù)第三段中的“UBTech said that the ability to pour drinks required visual servo( 伺服系統(tǒng)) technology using its cameras to judge the position of objects. The same methods allowed Walker to… draw a picture of a flower on a piece of paper at another point in the demo.”可知，UBTech表示，倒飲料的能力需要使用視覺伺服技術(shù)，即使用相機(jī)來判斷物體的位置。相同的方法使Walker在紙上繪制花朵的圖片。由此可知，位置判斷系統(tǒng)使機(jī)器人能夠畫畫。故選D。

【4】

推理判斷題。根據(jù)最后一段可知，UBTech繼續(xù)開發(fā)此開創(chuàng)性機(jī)器人，但尚未公開發(fā)布日期。該公司將Walker瞄準(zhǔn)家庭，重點(diǎn)是幫助老年人或打掃房子。要使其足夠穩(wěn)定以適應(yīng)所有這些不同條件是一個(gè)巨大的挑戰(zhàn)。但是，如果繼續(xù)推動(dòng)Walker的發(fā)展，那么該機(jī)器人最終將成為改變游戲規(guī)則的人。因此，從最后一段我們可以推斷出機(jī)器人可能會(huì)極大地影響我們的生活。故選C。

【題目】 Bees and butterflies are active during the daytime. They get a lot of attention for their roles as pollinators(傳粉者).But moths(蛾)aren't given the prominence they deserve.

Actually, moths are seen much less often, because they're active at night. Moth bodies often seem furry. Pollen—a yellow powder in the center of most flowers, from one flower sticks to their bodies and falls off when they move to other flowers. Scientists studied insects around nine ponds on farmlands in the United Kingdom. They visited these ponds once a month from March to October.

They studied three groups of insects: moths, bees that normally work together, like honey bees, and flying insects which work alone, such as butterflies. At the ponds, the scientists caught these flying insects and died to collect pollen from their bodies. In all, the scientists checked 838 moths, 632 other insects which work alone, and 1,548 honey bees.

By studying the pollen they collected, the scientists were able to see which plants the insects had visited. The moths had pollen from 47 different kinds of plants, including seven plants that bees don't normally visit. The honey bees had pollen from 46 different kinds of plants. The other insects that work alone had visited 45 different kinds of plants. Richard Walton, who led the study, says that bees usually choose the plants with the most nectar(花蜜)and most pollen. However, moths pollinate many different plants, filling in the gaps left by the daytime pollinators.

Not only do moths pollinate plants, they also provide important food for birds and bats.

But, like many other insects, moth numbers have dropped greatly in the last 50 years, mainly because of pesticides and the loss of natural lands. Just like bees and butterflies, moths are worth protecting. "Moths are by no means less important," says Dr. Walton.

【1】What does the underlined word probably mean in paragraphl?

A.Praise.B.Chances.

C.Concerns.D.Future.

【2】What is the second paragraph mainly about?

A.Moths and other insects' living habits.

B.Research on insects' spreading pollen.

C.Classification of insects by scientists.

D.The ways in which moths carry pollen.

【3】Compared with bees, which best describes moths?

A.They are less choosy.B.They eat less in the daytime.

C.They are more diverse.D.They carry more pollen.

【4】What is the best title for the text?

A.Moths Pollinate Plants Strangely

B.Moths Are More Vital Than We Think

C.Moths Help Bees to Pollinate Plants

D.Moths Visit Some Flowers Bees Skip

【題目】 One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend.【1】.

In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all.【2】 This was true even for those who didn’t log a great deal of time. The analysis divided people into groups, with 50 minutes or less per week representing the group that ran the least―but still ran. ‘‘Regardless of how much you run, you can expect such benefits,” says Zeljko Pedisic, one of the authors of the new analysis published in the British Journal of Sports Medicine.

The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (進(jìn)化) to do. 【3】 But as leisure-time exercise, running keeps us healthy. “One of the best ways to avoid having to see a doctor,” Zeljko says, “is to stay physically active.”

【4】 Running is good at guarding against cancer partly because it uses up blood sugar, starving the cancer cells that rely on it for fuel. And it protects you in other ways not necessarily measured in the latest research: by decreasing inflammation (炎癥), for example, which is at the root of many diseases, and stimulating the production of a protein that improves brain health.

【5】 Neither were how often people ran and the pace they kept. As long as you’re running, more isn’t always better, especially given that the risk of injury increases with repetition.

A.People may no longer hunt wild animals for their next meal.

B.The physical demands of running affect our body in a beneficial way.

C.Some people run to prevent disease, and others run because it makes them feel better.

D.Runners were 27% less likely to die for any reason, compared with nonrunners.

E.But researchers point out, to infer something like that, they need the whole population measured.

F.But new research suggests people may be able to get life-lengthening benefits by running for far less time.

G.The good news is that running more than 50 minutes per week wasn’t linked to additional protections against dying.

I am sorry to have received such poor service. I believe I have every right to ask you to deal with a problem. I hope that you either return my money back or deliver a new set of books to me. Therefore, I’d like to be informed of the process of your dealing with my complain.

Looking forward to your reply.

Sincerely,

Wang Ling
