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 . The Best National Parks to Visit in Winter

While most parks tend to draw families in the summer and fall, there are also ideal spots for adventurous winter trips.

Yellowstone National Park, Wyoming

The country’s oldest and best-known national park takes on an almost otherworldly atmosphere in winter: the air filled with rolling steam, the strong colors of hot springs, the surrounding white landscapes, let alone the impressive wildlife during this time, like bison, wolves, and playful red foxes. Just book a guided hiking tour to get a ranger’s perspective on the park and local people.

Joshua Tree National Park, California

With its giant red rocks and unique trees, you’ll feel like stepping onto a foreign planet as you spend hours hiking the Panorama Loop or Maze Loop. The park is recognized as an International Dark Sky Park, featuring virtually zero light pollution and the country’s best views of a starry sky.

Grand Canyon National Park, Arizona

A significantly lower number of visitors in winter means you can take in unblocked views of the South Rim, and get to see the rare beauty of the Grand Canyon dusted with snow. For those adventurous and daring, it is recommended to hike the Bright Angel Trail and take the chance to see the canyon’s wintertime wildlife, including mule deer, elk, and bald eagles.

Virgin Islands National Park, St. John

Surprise! Not all wintertime national park trips need to involve snow. Virgin Islands National Park is most famous for its white-sand beaches. You can also hike inland to visit old sugar plantations, or venture out to the water to swim along with sea turtles and manta rays. You will definitely enjoy a different winter here.

1. Which park will one choose if he/she is interested in stars?

A．Yellowstone National Park.	B．Joshua Tree National Park.
C．Grand Canyon National Park.	D．Virgin Islands National Park.

2. What do we know about the Grand Canyon National Park?

A．We can have a poor view of the South Rim there.	B．It lies in an area with rolling steam and hot springs.
C．There is a slight decline in visitor numbers in winter.	D．The Bright Angel Trail is challenging in cold weather.

3. Which activity is mentioned in all of the parks?

A．Hiking.

B．Skiing.

C．Swimming.

D．Hunting.

4 . 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.”

1. What was Taylor Engler doing?

A．Riding a bus.

B．Giving a lesson.

C．Designing a farm.

D．Experiencing VR.

2. What does the underlined part “kept abreast of" in Paragraph 2 mean?

A．Led to.

B．Focused on.

C．Caught up with.

D．Broken away from.

3. What did Lamb think of the use of VR in the classroom?

A．Helpful.

B．Troublesome.

C．Interesting.

D．Challenging.

4. What is the purpose of the text?

A．To point out the importance of practice.	B．To introduce the use of VR in teaching.
C．To give information about modern schools.	D．To show the appearance of VR technology.

5 . There are three things you can watch forever: Instagram feeds, YouTube videos and water. Among them, water is definitely something no one argues about, and there are many unusual water attractions that you can find around the world.

Bangkok Floating Markets

There are many floating markets where goods are sold from boats. While modern markets are more popular, floating markets still are a huge attraction for local tourism. Any visitors can purchase local foods and traditional handcrafted (手工的) souvenirs. Bargaining is a part of experience. So, start low and get the price you are ready to pay.

Bregenzer Festspiele

The Bregenz Festival is held every year from July to August in Vorarlberg. It has the world’s largest stage on the water. The performances are different every year but they are usually united by one theme. The decorations are very impressive and are worth seeing.

Marina Bay Stadium

This stadium was built as a temporary solution while Singapore National Stadium was rebuilt. The stadium was used for the opening and closing ceremonies during 2010 Summer Youth Olympics. It was a floating platform where the Formula One Grand Prix event was successfully held.

Archipelago Cinema

Archipelago Cinema is probably one of the world’s most scenic open-air cinemas that floats in the middle of a lake. The cinema was designed by German architect Ole Scheeren, who built it using techniques popular among local people. This cinema stage was built specially for the film festival Film on the Rocks Yao Noi.

1. What is special about Bangkok Floating Markets?

C．They were both built for a special purpose.

D．They both provide visitors with sports events.

6 . How does it happen that some people never have to see the doctor while some are wasting much money in hospital? The answer lies in their proper, healthy diet. A balanced diet actually means eating all kinds of foods to provide the body with all the nutrients (营养物) it needs for its daily work. It means eating the right type of foods and eating a right amount of food for each meal.

Each food group contains different kinds of nutrients, and our body surely needs all of these, but in different amounts, and it differs from person to person. When it comes to going on a healthy diet, one size is not suitable for all. Everyone leads a different lifestyle, and has different jobs and fitness levels.

A balanced diet matters for everyone. If the body gets all the required nutrients, it’ll improve the immune (免疫) system, which prevents all kinds of diseases. A balanced diet would also be good for the state of mind and then help you remember something better. What’s more, if the body is supplied with all the necessary nutrients, the skin and hair also become healthier. A balanced diet also prevents our body from aging. As a result, you’ll have a more youthful look.

However, for a healthy body, a balanced diet is not enough; it has to be combined with the proper amount of sleep and exercise. These three things, when included in your daily routine, will make sure that you not only have a healthy body but also a healthy mind. So, go ahead and adopt a healthier lifestyle!

1. What does the underlined word “differs” in Paragraph 2 mean?

A．Comes.	B．Grows.
C．Changes.	D．Matters.

2. What is Paragraph 3 mainly about?

A．The choice of a balanced diet.

B．The features of a balanced diet.

C．The importance of a balanced diet.

D．The relationship between diet and aging.

3. What can we infer from the last paragraph?

A．A balanced diet doesn’t work alone.

B．Mind is closely linked to the body.

C．Exercise is the most important.

D．It's easy to get a healthier lifestyle.

4. Why is the question raised in the first paragraph?

A．To show problems.	B．To give evidence.
C．To list some facts.	D．To lead in the topic.

7 . Over the last few weeks, I have been back and forth to the hospital and working with my doctors and medical technicians. I feel very _________ and appreciative of all the great minds and effort involved in _________ my illness. I found I have become _________ grateful to those human beings who invented the many medical _________ that have saved so many lives and _________ so much pain.

With everything I _________, I couldn’t help thinking about many life-changing _________ that we humans have come up with, from the fairly simple stethoscope (听诊器) to more _________ inventions like X-rays, and other great devices. Of course, one of the biggest, most basic inventions was the _________. It changed the world in all kinds of ways. Without wheels, we’d have no __________, such as bikes, cars, trains, or airplanes.

__________many inventions human beings have invented through the ages, I __________ some very popular inventions. It is __________ to imagine what if we live without them. These __________ things like tape, nails, Post-it notes, DNA testing, the Internet, vaccines, and medical imaging.

Some inventions were accidental __________ but many were matter of simply trying to solve a problem. If we pay attention to what we experience and really put our __________ to it, there is no reason why we couldn’t come up with some new inventions ourselves. Maybe make a list of __________ items, systems, and habits we all have, and then go up and down the list and see if we can put two or three items together in a way to come up with a new __________ or better way to handle life and the __________ in it. Give it a try and see what we can come up with, We could __________ ourselves, and others as well!

8 . 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.

9 . Under the background of the slow growth of its total population to 1.44 billion, China has seen a sharp rise in older adults over the past decade, solidifying the country’s rapidly aging pattern, the latest national census (人口普查) data shows. The population on the Chinese mainland increased by an average of 0.53 percent annually during the past 10 years to 1.41 billion, compared with an annual growth rate of 0.57 percent from 2000 to 2010, according to the 7th national census published by the National Bureau of Statistics.

“The growth of the total population has slowed down but remains at a steady pace,” Ning Jizhe, head of the bureau, said at a news conference. “Based on trends in recent years, China’s population will grow at an increasingly slow rate in the future while remaining above 1.4 billion.” The increasing elderly population has become a defining feature of the past decade.

Ning said an aging society will set the tone for China's population structure for a long time, presenting challenges and opportunities. “A graying population will pile pressure on supply of labor force and social services, as well as adding to families’ elderly care burden. But more elderly people could also motivate consumption of products and services targeting this age group, and advance the development of some technologies,” he said.

Ning added that those between the ages of 60 and 69, who are equipped with knowledge, experience and skills and are generally in good health, make up nearly 56 percent of all older adults. “Their potential to continue making contributions to society and playing a constructive role is big,” he responded to a question on the outlook for raising the retirement age and carrying out other potential measures aimed at addressing the aging trend. Some population economists also said the latest number and proportion (比例) of elderly are largely within predictions, and the aging trend will continue for a long time.

1. What does the 7th national census data show?

A．The aging population of China has risen rapidly.

B．The annual growth rate has increased by 0.04%.

C．The annual growth rate was 0.57% during the past 10 years.

D．The total population of Chinese mainland increased to 1.44 billion.

2. What does Ning Jizhe say about the growth of graying population?

A．It is beyond predictions.	B．It brings few advantages.
C．It has sharply slowed down.	D．It will increase pressure on family.

3. What is Ning Jizhe’s attitude to the graying population?

A．Objective.

B．Doubtful.

C．Unclear.

D．Negative.

4. What can be a suitable title for the passage?

A．The aging trend brings problems

B．An aging society presents opportunities

C．China’s population gets old as growth slows

D．Measures are to be taken to tackle the aging trend
