What if you arrived home to find a delicious hot meal waiting for you, prepared by your own kitchen robot? It might sound like science fiction, but professors at the University of Tokyo have taken the first steps toward making that a reality. The team recently introduced a human-shaped kitchen robot that can pour tea and other drinks into cups and serve them to guests. When teatime is over, the robot can also wash the dishes and put them away.

In California, another interesting kitchen robot has been developed, called Readybot. It can pick up objects and either store them in cabinets (櫥柜) 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 (憂慮). Not everyone (especially parents) would be comfortable with the idea of robots in their house, manipulating hot pans and sharp knives. The European Commission recently funded(資助) 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.”

1.Compared with Readybot, the Japanese robot ________.

A. is more popularB. performs more jobs

C. moves more quicklyD. looks more like a person

2.Readybot can now be used to ________.

A. drive you aroundB. clean your kitchen

C. prepare food for youD. work for office workers

3.The underlined word “manipulating” can best be replaced by ________.

A. inventingB. avoidingC. controllingD. making

4.In the last paragraph the author says that parents ________.

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

You may complain that there are too many tests on the way to college entrance, but an increasing number of students want to take one more. That is the Scholastic Aptitude Test, or SAT, an American test for students who intend to apply for college admission.

Chen Huanlu, aged 18, from Shandong Province took part in the SAT subject tests (SAT 2) in Hong Kong on June 2. She has also been scheduled to take the SAT reasoning test (SAT 1) in October.

“I hope to study environmental engineering at an American university, where I may have more opportunities to get cutting-edge (前沿的) knowledge in this area,” said Chen.

However, not all SAT test takers want to apply to American universities.

“I wanted to see how I would do when faced with plenty of stress and also to evaluate (測評) my scholastic level by an American standard. The SATs made my school life more diverse,” said Senior 2 student Zhou Yuxiang from Sichuan Province.

Zhou, aged 17, a top student in his school, was inspired by some of his friends. They have taken this test and been admitted to American universities, including Harvard and Yale. Last winter vacation he took a 20-day SAT course at Chengdu New Oriental School.

“As I prepared for the test in the following months, I was forced to balance my everyday schedule better. Fortunately I was optimistic enough to have undergone the most difficult time,” he said.

In May and June, Zhou flew alone to Hong Kong to sit for the SAT1 and SAT2.

“They are both the standards which have been set for us to reach. What we should do more sensibly is to try harder to prepare for them. Survival of the fittest (適者生存) is true both in America and in China. That is something I have learnt beyond the SAT itself,” he said.

1. The SAT is a test designed mainly for _________.

A. Chinese students who want to go to college in America

B. American students who intend to apply for college admission in China

C. students who plan to apply for American universities

D. students who want to learn about the survival of the fittest

2. What can we learn about Chen Huanlu according to this passage?

A. She doesn’t like the college entrance examination in China.

B. She has taken part in both SAT 1 and SAT 2 in June.

C. She is interested in environmental issues.

D. She wants to get cutting-edge knowledge from SATs.

3. By taking Zhou Yuxiang for example, the author wants to tell us that ________.

A. all the students who take SATs intend to apply to American universities

B. some SAT takers simply regard the SAT as a challenge

C. he just takes the test for fun

D. SAT 1 and SAT 2 have something in common

4. What do Chen Huanlu and Zhou Yuxiang have in common?

A. They both took part in the SAT subject tests in Hong Kong.

B. They are both students of Senior 2.

C. Both of them attended a SAT course at New Oriental School.

D. Both of them came from the top schools.

Singapore is building an airport where indoor trees, waterfalls and a ‘rain vortex’ sit alongside check-in queues, waiting rooms and baggage carousels(傳送帶).

Where once sat a car park, there will soon be thousands of trees and plants across 22,000 sq metres of landscaped indoor parklands. This will be joined by a 40m-high indoor waterfall, expected to be the world’s tallest. These are the plans for the new 3.5 hectare ‘Jewel’ development at Singapore’s Changi Airport, scheduled to open in 2018; a five-storey, 134,000 square metre complex, mixing natural outdoor plants with modern airport facilities.

“The aim behind the introduction of such lush(茂盛的) landscaping is purely to provide all visitors with a memorable experience, one where they are surrounded by nature and greenery,”says Philip Yim, Chief Executive Officer of Jewel Changi Airport Development.

Promised sustainability(持續性) measures include “extensive usage of photovoltaic panels(光電板)”to produce renewable energy, as well as encouraging the use of natural lighting and a “high efficiency” air-conditioning system.

The indoor waterfall, named the “Rain Vortex”, will make use of special lighting effects to change at night into what is promised to be a dramatic light and sound show. “The Rain Vortex is one example of how sustainable design plays an important role in the planning of the attraction,” says Yim. ‘In the event of a rain storm, the power of the rain water will flow naturally through the oculus. The excess rain water collected will be used for irrigation of the landscaping at Jewel.’

Yim quotes the popular reputation Singapore enjoys as “the garden city”, where greenery is recognised as an essential part of the urban landscape, an attractive image which clearly inspires Jewel’s design.

However, it remains to be seen whether, beyond the aesthetic (審美的) appeal, Jewel can add genuine environmental things to something as un-environmental as an international airport.

1. What can we learn about the “jewel” development Singapore’s change Airport?

A. It is being built on an old car park at present.

B. It has been planned and is being built.

C. It will be the world’s tallest airport.

D. Acts of kindness can make a difference.

2. To keep the airport developing sustainably, it is advised to .

A. use no electric lights

B. use more air-conditioners

C. make full use of natural water

D. try to produce renewable energy

3.What can we infer about the Rain Vortex?

A. It can transform into a dramatic show at anytime.

B. Its design will be a great success environmentally.

C. It will produce water to irrigate plants.

D. A rain storm may make it look prettier.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

1. The writer of this passage must be ______.

A. an American B. a Chines

C. a professor D. a student

2. Which of the following statements is TRUE according to the passage?

A. Friendships between Americans usually extend deeply into their families.

B. Friendships between Americans usually last for all their lives.

C. Americans always show their warmth even if they are very busy.

D. Americans will continue their friendships again even after a long break.

3. The underlined words “generous with our time” in Paragraph 3 probably mean ______.

A. strict with time B. serious with time

C. careful with time D. willing to spend time

4. A suitable title for this passage would probably be “______”.

A. Friendships between Chinese

B. Friendships between Americans

C. Americans’ hospitality

D. Americans’ and Chinese’s views of friendships

Exercise may help to safeguard the mind against depression(沮喪) through previously unknown effects on working muscles, according to a new study involving mice.

Mental health experts have long been aware that even mild, repeated stress can contribute to the development of depression and other mood disorders in animals and people. Scientists have also known that exercise seems to cushion against depression. But precisely how exercise, a physical activity can reduce someone’s risk for depression, a mood state, has been mysterious. So for the new study, researchers at the Karolinska Institute in Stockholm studied the brains and behavior of mice in a complicated and novel fashion.

We can’t ask mice if they are feeling cheerful or in low spirits. Instead, researchers have pictured certain behaviors that indicate depression in mice. If animals lose weight, stop seeking out a sugar solution when it’s available — because, probably, they no longer experience normal pleasures — or give up trying to escape from the cold-water zone just freeze in place, they are categorized as depressed. And in the new experiment, after five weeks of frequent but low-level stress, such as being lightly shocked, mice displayed exactly those behaviors. They became depressed.

The scientists could then have tested whether exercise blunts (延緩) the risk of developing depression after stress by having mice run first. But, frankly, from earlier research, they wanted to know how, so they bred pre-exercised mice. A wealth of earlier research by these scientists and others had shown that aerobic exercise, in both mice and people, increases the production within muscles of an enzyme (酶) called PGC-1alpha. The Karolinska scientists suspected(懷疑) that this enzyme somehow creates conditions within the body that protect the brain against depression. Then, the scientists exposed the animals, which without exercising, were in high levels of PGC-1alpha to five weeks of mild stress. The mice responded with slight symptoms of worry. But they did not develop depression. They continued to seek out sugar and fought to get out of the cold-water zone. Their high levels of PGC-1alpha appeared to make them depression-resistant(抵抗的). Finally, to ensure that these findings are relevant to people, the researchers had a group of adult volunteers complete three weeks of frequent endurance training, consisting of 40 to 50 minutes of moderate cycling or jogging. The scientists conducted muscle biopsies (活體檢查) before and after the program and found that by the end of the three weeks, the volunteers’ muscle cells contained substantially more PGC-1alpha than at the study’s start.

The finding of these results, in the simplest terms, is that “you reduce the risk of getting depression when you exercise,” said Maria Lindskog, a researcher at the Karolinska Institute.

1.The researchers at the Karolinska Institute in Stockholm conducted the new study hoping to know ________.

A. if exercise cushions against depression

B. what can lead to depression in animals and people

C. if stress can contribute to the development of depression

D. how exercise contributes to reducing someone’s risk for depression

2.We can infer from the new experiment conducted by researchers at the Karolinska Institute that mice are depressed except when ________.

A. they attempt to escape from the cold-water zone

B. they stop searching for the sugar water

C. they stand still in place

D. they can’t experience normal pleasures any longer

3.Researchers asked a group of adult volunteers to complete three weeks of frequent endurance training in order to ________.

A. know if exercise can help to safeguard the mind against depression

B. know if they can endure 40 to 50 minutes of moderate cycling or jogging

C. ensure they can lose weight after moderate cycling or jogging

D. confirm the findings above are also relevant to people

4.It can be concluded from the passage that ________.

A. the mice with high levels of PGC-1alpha are easier to develop depression

B. athletes are more likely to develop depression than ordinary people

C. the enzyme called PGC-1alpha helps to reduce depression

D. in the past mental health specialists didn’t know exercise could help reduce depression
