题目内容

In California, another interesting kitchen robot has been developed, called Readybot. It can pick up objects and either store them in cabinets (橱柜) or put them in the trash. It also carries a separate floor-cleaning robot that can operate by itself. Unlike the Japanese robot, Readybot just looks more like a large box with arms and wheels.

Readybot was created by engineers and designers who established a club called the Readybot Challenge. They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks. Readybot is just the first step in their plan to create a robot that can do jobs not only in kitchens but in other rooms of homes and in offices as well.

Clearly there are technological difficulties to solve before robots can cook a complete dinner, and there are also many safety concerns (忧虑). Not everyone (especially parents) would be comfortable with the idea of robots in their house,manipulatinghot pans and sharp knives. The European Commission recently funded(资助) a project to study these concerns. According to lead researcher Professor Chris Melhuish, “Enabling robots to work safely with humans is a key need for the future development of robotics.”

A. is more popular B. performs more jobs

C. moves more quickly D. looks more like a person

A. drive you around B. clean your kitchen

C. prepare food for you D. work for office workers

A. inventing B. avoiding C. controlling D. making

A. have shown great interest in kitchen robots

B. can’t wait to use kitchen robots in their homes

C. might think that kitchen robots could be dangerous

D. found out how to operate robots safely

When Taking an Uber-Should You Tip or Not?

Taking an Uber car may no longer be a direct driver-passenger and guilt-free experience. The ride-sharing experience is about to get awkward.

With the wide application of the Internet, Uber, a new approach to your destination instead of taking an ordinary taxi, has become more popular recently. However, benefits won’t come without its fair share of drawbacks.

Uber drivers are a part of the so-called sharing economy: They use their own vehicles, receive customer reviews via the app’s five-star rating system and make their own hours. Unlike other services, Uber claimed that drivers all over the country could clearly alert customers that tipping is not included. Those drivers that expect to be tipped can make their wishes known. But the company is holding to its official no-tip-required line, according to its website. “Once you arrive at your destination, your fare is automatically charged to your credit card on file—There’s no need to tip.” Although drivers value their independence—the freedom to push a button rather than punch a clock, lack of a clear policy, however, leaves Uber drivers in a vulnerable(脆弱的) position: If they ask a customer for a tip or put up a sign, that customer could give the driver a low star-rating, and the driver could finally be deactivated from the app.

But has the company done a good job working with customers? Some observers say that this new grey area for tipping will create awkwardness about whether they should tip or not—something most Uber customers have not had to deal with until now. Uber did not respond to customers’ comment, just leaving their rating in the air（ignoring it）.

Providing an option to tip on an app sends a clear message to customers to reach into their pockets. Nearly 30% people would be more likely to leave a tip if they were presented with a “no tip” button, according to Guinn’s 2015 survey of roughly 500 people. When people are presented with three tip choices—20%, 25% or 30%—they’re more likely to choose the middle option even if it’s more than the traditional 20%, according to a separate 2014 analysis of 13 million New York City taxi rides.

If the service is twice as expensive during a rain storm or public transport delay, the customer has the right not to tip. However, if the driver is extra helpful or avoids traffic to reach your destination in a more timely manner, you could give an extra tip, says Uber, who will leave tipping options in the hands of the consumer rather than the app.

1. Compared with taxi drivers, Uber drivers ______.

A. enjoy more freedom and choices

B. support the company’s practice

C. clock up the miles while driving

D. receive customers reviews directly

2.The underlined word “deactivated” in Paragraph 4 probably means ______.

A. removed B. degraded C. tracked D. charged

3.From the survey we can conclude most customers ______.

A. would probably tip if there is an option

B. usually do as the “no tip” sign suggests

C. tip because of Uber drivers’ good service

D. are disappointed to reach into their pockets

4.What causes the awkwardness between Uber drivers and their customers?

A. Customers take advantage of the new grey area for tipping.

B. There is no specific policy from the Uber to follow.

C. It’s up to customers to decide the drivers’ earnings.

D. Customers tend to pay least among the 3 choices.

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

1.The difficulty the team of engineers met with while making the robotic fly was that ________.

A. they had no model in their mind

B. they did not have sufficient time

C. they had no ready-made components

D. they could not assemble the components

2.It can be inferred from paragraphs 3 and 4 that the robotic fly ________.

A. consists of a flight device and a control system

B. can just fly in limited areas at the present time

C. can collect information from many sources

D. has been put into wide application

3.Which of the following can be learned from the passage?

A. The robotic flyer is designed to learn about insects.

B. Animals are not allowed in biological experiments.

C. There used to be few ways to study how insects fly.

D. Wood’s design can replace animals in some experiments.

4.Which of the following might be the best title of the passage?

A. Father of Robotic Fly

B. Inspiration from Engineering Science

C. Robotic Fly Imitates Real Life Insect

D. Harvard Breaks Through in Insect Study

Have you ever heard of an insect called the cicada(蝉)? 1. But they have an interesting internal clock that tells them when to go aboveground.

Every 17 years, billions of the noisy Brood V cicadas(十七年蝉) will swarm(成群出现) to northeastern parts of the US, including New York, Ohio and Pennsylvania. 2.But there are usually a lot less of them compared to the Brood V cicadas.

3. According to Discovery News, these insects started their lives in 1999. And as their 17-year life cycle comes to an end, they go aboveground when their underground homes get warmer 64 degrees Fahrenheit (about 18℃) to be exact.

Then the females will lay hundreds of eggs in trees, and after about four to six weeks, the mother and father cicadas will die. 4.

While they can be kind of annoying, these insects don’t harm humans, but they do make a lot of noise during their time aboveground. 5.

However, since there are so many of the 17-year cicadas, the amount of laid eggs can sometimes harm small trees and bushes. But after this summer, these insects will mostly mind their own business until 2033.

A. That sound is the male cicadas attracting the female cicadas.

B. The cicada insects are common in summer, especially in August and can be found in July as well.

C. There are other kinds of cicadas that come around once a year or every 13 years.

D. The baby cicadas will go underground, and the 17-year cycle will start over again.

E. As a matter of fact, people like to eat them in some cultures.

F. Well, a special kind of these insects live underground in the US for most of their lives.

G. This is what makes Brood V cicadas so special.

Red is used in many American expressions. It can be used to show1.(happy), as in “a red- letter day”. This is a day when something special happens. The expression is probably based2.church customs. For almost six hundred years, church calendars(日历)3.(mark) with red to indicate special holidays. Today’s calendars are still marked that way with the4.(meaning) of holidays and special days printed in red.

The expression “a red-letter day” is often heard in everyday life. A red-letter day is5.day when people are feeling quite happy. It may be a day6.you’ve long waited for, a wedding day, for example, or it may be a day with a happy surprise. You might tell your friends that yesterday was a red-letter day,7.you won sonic money in the state lottery (彩票).

“Rolling out the red carpet" is another8.(common) heard expression, which9.(represent) a warm welcome of any kind. A city may “roll out the red carpet” for its baseball team when the team arrives home after winning the championship.

Red is also used in some expressions that are not happy. Red-handed is one. To be caught red handed is to be caught10.(perform) a wrong act.

In the village where I grew up, everyone knew an old man, who lived a simply life and spent all his time painting. The villagers used to admiring his works and he often gave his paintings to his friends. Whenever he was offered money, he would not take them. He said he painted for a pleasure. He once gave one of his paintings to my father, whom actually wasn’t interested in art. Years later I found it in our old house. By that time the old man has died and people started to recognize his paintings as great works of art, which was worth lots of money. An art gallery made me an offer of $5,000 for this painting and I nearly sold it, so then I decided not to. It always reminds me my childhood and of the old man who didn’t really want to make money by paint.

When I was three years old, my parents discovered I was totally deaf. After consulting with many doctors, they made a decision about my ______. Instead of sending me to a private school for the deaf, they decided to send me to a ______ one.

The teachers didn’t know what to do with me. Because of my hearing disability, I was constantly________ everyone, “What did he/she say?” But I _______that everyone would soon grow tired of repeating everything back to me. Since fitting in was so ________ to me, every time people around me laughed or smiled, I did the same even though I__________had no idea what was going on. On the surface, I was _______, but in reality, my self-esteem（自尊） was quite low. Mrs. Jordan, my 5th grade teacher, _______ all of that with a simple three-word phrase. One morning, she asked the class a question. I read her lips and _______raised my hand. I couldn’t________it –for once I knew the ______. But, when she called on me, I was_______. I took a deep breath and nervously answered Mrs. Jordan’s question.

I’ll never forget what __________ next. With sparkling eyes and a wide smile she cried, “That’s right, Stephen!” For the first time in my young life, I was an instant star. My heart burst with pride.
