2 . One thing that sets humans apart from other members of the animal kingdom is our tendency to develop customs and traditions. Here are some astonishing customs from around the world.

An odd custom associated with the United States is its complicated tipping culture. Unlike many other countries that don’t tip at all or that only tip in small amounts when the food is particularly good, tipping is actually mandatory at most restaurants in the US. To put it another way, customers have a duty to leave between 10-20 percent of the bill in tips. Wait staff rely on these tips for a living because legal wages for waiters are low. Furthermore, there are rules for tipping bartenders, delivery people and other service personnel. While some criticize this practice as irrational, there’s no doubt that tipping culture in the US gives an incentive for waiters and waitresses to provide better service.

Some countries find the act of pointing with the index finger to be rude. While members of most cultures would probably agree that pointing fingers, both literally and figuratively, isn’t exactly the nicest thing in the world, in countries like Malaysia and Indonesia, this gesture can be seen as incredibly offensive. Instead, it is customary to gesture towards things with the thumb as this is seen as a more polite option. In many countries in Africa, pointing is reserved for inanimate objects only, not people.

Most societies around the world have rules about table manners. For western cultures, noisily consuming food is considered rude. In Japan, however, making slurping(啧啧响的)sounds while eating has an entirely different meaning. This might have something to do with the fact that in western countries, noodles are properly consumed by twirling(缠绕)them on a spoon before putting them in the mouth. Meanwhile, the Japanese simply slurp up their noodles without contorting them first, an act that is naturally noisier than the former. Making slurping sounds when eating noodles in Japan is a way of indicating that you’re rely enjoying them. Some scientists even argue slurping invites air into the mouth and actually enhances the noodles’ flavor.

1. What does the underlined word “mandatory” in paragraph2 probably mean?

A．Required by tradition.	B．Highly spoken of.
C．Changeable over time.	D．Popular among people.

2. What does the author think of tipping?

A．It is totally unreasonable.	B．It must follow a fixed standard.
C．It can improve the quality of service.	D．It should only target waiters and waitresses.

3. Which practice is acceptable according to the text?

A．Skipping tipping in the USA.	B．Twirling noodles on a spoon in Africa.
C．Pointing with the index finger in Indonesia.	D．Making sounds while eating noodles in Japan.

4. Where is this text probably taken from?

A．A research paper.	B．A travel brochure.
C．An online advertisement.	D．A popular magazine.

3 . It was a February afternoon in a Brooklyn classroom. Sixteen-year-old Taylor Engler came face to face with a cow. But it was all in her head. She was transported by a virtual reality (VR) headphone. It took the Berkeley Carroll School junior and eight other classmates to a northern New York farm. The farm was 250 miles away. For students, the technology means field trips are no longer kept within the length of a bus ride.

It's unknown how many classrooms have or will use the technology, but experts say few classrooms do or will do. Headphones that require a user's phone can cost as little as $20 or $30, but systems and software for classes run into thousands of dollars. The problem of not having good software is disappearing as more companies enter the market. But the rules for use haven't kept abreast of the development of the technology. In New York, for example, virtual reality lab experiments are not included in the state's hands-on lab time requirements.

Experts say science classes are where virtual reality holds promise for classrooms. “The biggest problem, I think, is going to be how closely it mimics the real world." That's according to David Evans, the director of the National Science Teachers Union. However, he said, “The ability to do dangerous things and to run many, many more cases in a virtual space as opposed to the real physical space stands for a huge learning chance.”

Lamb taught chemistry and he agreed. “Too often in schools, when you do experiments in labs, you mix these together, you mix those together and you get this result. And if you don't get that result, you have done something wrong. But we don't have enough resources for you to redo it, “he said. “In virtual reality, all I do is hit reset on the computer. I don't have to actually use chemicals.”

5 . In a weightless, microgravity environment like space, how can someone with sight or mobility problems navigate in the space station? As scientists continue to push the boundaries of spaceflight and the possibility of human life on other planets, how can we build space infrastructure (基础设施) friendly to all humans？

The Mission AstroAccess project aims to answer these questions, starting with a historic parabolic (抛物线的) flight that took off from Long Bench on Oct. 17, 2021. A group of 12 disabled scientists, students, athletes and artists launched into a zero-gravity environment as a first step. To get a better idea of what is needed for more inclusive (包容的) space travel, AstroAccess plans to conduct a series of follow-on parabolic flights after the first launch. On these flights, a plane flies up to an altitude of around 32, 000 feet and then begins a descent at about 4 miles per second. This quick descent creates a microgravity, weightless effect lasting roughly 30 seconds. Afterwards, the plane climbs back up to a stable altitude, and repeats the process again.

The 12 AstroAccess Ambassadors selected for this first microgravity flight included four blind or low-vision Ambassadors; two deaf or hard-of-hearing Ambassadors；and six with mobility disabilities, all carrying out various tasks in the weightless environment. One of the challenges was seeing whether all members could perform basic safety and operational tasks. The crew also tested whether sound beacons (声信标) could be used for blind members to direst themselves, They are also investigating how American Sign Language will be impacted by microgravity.

“My whole career goal is to make the average person able to go to cuter space, where you don’t have to be a crazy trained astronaut with perfect physical abilities and health to visit cuter space,” said Brenda Williamson, head of the AstroAccess logistics committee. “I grew up on Star Trek, so the idea of exploration is really important.”

1. Why is the Mission AstroAccess project carried out？

A．To expose the disabled to zero gravity.

B．To train a group of disabled astronauts.

C．To involve all humans in spaceflight.

D．To build mobile space infrastructure.

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

A．Going down.

B．Going up.

C．Taking off.

D．Touching down.

3. What do we know about the 12 selected Ambassadors？

A．They all have mobility problems.

B．They communicate by sign language.

C．They do scientific research in the lab.

D．They perform tasks in weightlessness.

4. What does Brenda Williamson think of the project？

A．Meaningful.	B．Successful.
C．Unrealistic.	D．Challenging.

6 . My brother Joe liked driving cars. He was especially _________speed. It was enough to make mother _________.

As a little boy, Joe would often say to me. “Sister, when I am old enough to drive my own car, I will fly so fast that angels will run scared.” With a big grin (咧嘴笑), he would _________ the scene. I could have told him it would _________ happen. But I didn’t tell him that.

Joe was born blind. But he could _________ like anyone. I didn’t want to be the one to _________ Joe’s dreams._________ would do that for him, soon enough. Up to then, didn’t he _________ his happiness？

Growing up is a _________ between disappointment and surprise, between dreams and reality. When Joe was 12, I think he knew he would never get a license (驾照). As with the other hard facts of life, he seemed to accept it without question or sadness, as if it were __________ more than a card drawn at random (随机地).

One hot summer day when he was 16, Joe, with the help of stick, found his way to my stepfather’s car.

He felt the heat of the __________, opened the door and climbed in. Under the seat, he discovered 6 cans of beer. And he drank all. He found the keys, shouted, “Hooweeee!” and __________ it up.

7 . According to the US economist Robert Gordon, all the “impressive stuff” has been created; we have run out of the big, life-changing ideas needed to encourage rapid economic growth and engineers are now only just making slight changes. Inventions such as mobile phones, Gordon says, have had less impact than, for example, the invention of indoor plumbing (管道系统).

But this is a misunderstanding of how engineers work. There is no “Wow!” moment. The development of new technology happens little by little. You build upon the work of those before you, thinking about what could be done better and what could be improved. It’s an unending task. Michael Faraday invented the first electric motor. But Faraday’s breakthrough followed William Sturgeon’s invention of the electromagnet (电磁铁), and Alessandro Volta’s invention of the battery before that. Faraday would have expected future engineers to pick up the baton (接力棒) later down the line.

Reduced energy supplies, increasing populations and mass urbanization keep clever young engineers awake at night. Those, for example, who enter the yearly James Dyson Award invent things that solve these problems and more. The 2012 winner Dan Watson designed a clever system of escape rings for fishing boat nets that deals with the issue of overfishing — not an exciting topic, but his invention is exceptional. Human inventiveness remains unreduced in the face of new global challenges.

Our problem is patience. We expect new technology at a rate like never before. I can’t tell you the world’s next big invention. Last week brought news that we’ve invented a new way to deal with antibiotic-resistant bacteria. Next week may bring a major development in another field. The biggest thing holding invention back is our impatience. With enough time and support, bright young engineers will develop exciting new technology to solve the world’s trickiest problems. Many have already begun.

1. Why does the author mention what Robert Gordon says?

A．To introduce the topic.	B．To illustrate a new invention.
C．To provide background information.	D．To express his opinion about the topic.

2. What can we infer from Michael Faraday’s example?

A．New technology has been developing step by step.

B．New inventions fail to deal with new global challenges.

C．Michael Faraday set a good model for William Sturgeon.

D．Technology helps future engineers achieve success smoothly.

3. What makes Dan Watson’s invention excellent?

A．His young age.	B．His patience with technology.
C．His effort to solve real world problems.	D．His wish to win the James Dyson Award.

4. Which word best describes the author’s attitude to technological development nowadays?

A．Doubtful.

B．Uncaring.

C．Disapproving.

D．Optimistic.

8 . New England holds some special museums. They are devoted largely or entirely to the work of just one person. And they are the artists’ birthplaces or onetime homes. Here are four examples of such museums.

Cyrus E. Dallin Art Museum

The name Cyrus E. Dallin (1861-1944) might not be familiar, but several of the artist’s sculptures (雕塑) are, especially those related to Native Americans. A good example is his “Appeal to the Great Spirit” standing in front of the Museum of Fine Arts. Born in Utah, he lived in Arlington for the final four decades of his life. The museum is in the Jefferson Cutter House, an 1830 Greek styled building.

Norman Rockwell Museum

Rockwell (1894-1978) was America’s well-known artist. The museum, founded in 1969, moved into its present location, Robert A.M. Stern-designed building in 1993. Its 998 paintings and drawings are the largest single collection of Rockwell's artworks.

Kids 16 and under: free; adults: $20; the old: at a 10% discount (折扣)

Edward Gorey House

Edward Gorey (1925-2000) was an artist, but he was also an author and clothes designer. Gorey bought this 18th-century house in 1979 and lived there for the rest of his life. Edward Gorey House is also known as the Elephant House. Gorey had respect for animals. The activities of the house, from art education to exhibits, show Gorey's support of animal well-being.

Gibert Stuart Birthplace and Museum

Gilbert Stuart (1755-1828) is responsible for what may well be the most familiar work of any American artist, His drawing of George is the basis of the first president’s portrait (画像) on the dollar. Stuart painted more than a thousand portraits throughout his life.

1. What do we know about Cyrus E. Dallin?

A．He built the Jefferson Cutter House.

B．He lived in Arlington for half a century.

C．He was best known for his Greek styled sculptures.

D．He created famous works related to Native Americans.

2. How much will an old couple pay to enter Norman Rockwell Museum?

A．$36.

B．$40.

C．$60.

D．$72.

10 . Although Friends came to an end in 2004, it’s still considered one of the best sitcoms to ever make its way onto our screens. This show thrust the likes of Lisa Kudrow, Matthew Perry, Jennifer Aniston, Matt LeBlanc, David Schwimmer, and Courteney Cox into the limelight (聚光灯), and everyone had their favorites. Women wanted to have their hair cut just like Rachel, many people wanted to be as confident as Joey, and others wanted to be able to sing just like Phoebe! However, it seems as though Lisa Kudrow’s experience on the set of Friends wasn’t as perfect as it seemed.

Recently, Lisa Kudrow was asked to speak on Marc Maron’s podcast (播客), and she opened up about her experiences with her own body image. She noted that, while working on Friends, she would often compare herself to her co-stars. She would look at Jennifer Aniston and Courteney Cox, and she would then see her flaws compared to their perfections. She would see them as extremely thin and beautiful women, but then she looked at herself on her screen and saw someone who was much larger.

Because she often felt as though she was less of a woman because she felt larger than her co-stars, Lisa would lose weight on purpose to feel better about herself. The more she lost weight, the more she received compliments from those who knew her, and complete strangers. This heightened the idea that she needed to be thin to be beautiful.

Now, Lisa has put weight back on and feels more beautiful than ever.

1. Who were most probably Matthew Perry and Jennifer Aniston?

A．Stars from Friends.	B．Characters from Friends.
C．Fans of Friends.	D．Coauthors of Friends.

2. Why did Lisa Kudrow have a different experience on the set of Friends?

A．Because she didn’t work well with other stars.

B．Because she thought she was too fat.

C．Because she wasn’t her audience’s favorite.

D．Because she was poor at playing her role.

3. What can you learn from Lisa’s experience?

A．Don’t think much of your appearance.

B．Don’t express your true feelings to your fans.

C．Don’t focus much on the comments of co-stars.

D．Don’t make too much comparison with others.

4. What does the underlined word “compliment” in paragraph 3 most probably mean?

A．Dislike.

B．Comment.

C．Praise.

D．Requirement.
