1 . Many factors in our life can lead to anxiety and stress. Luckily, there are several simple ways of relieving stress. Most of these steps are responsible for the improvement of your overall health as well.     1     Physical activity leads to a lowering of the overall stress levels and it also improves your quality of life both physically and mentally.

Any physical activity improves the capability of your body to use oxygen and it also leads to better blood flow.     2     Exercise increases the production of endorphins(内啡肽) in the brain. The endorphins are responsible for the “feel good” effect you feel and they also provide you with the much-desired “runner's high”. In simple terms, it is the sense of wellbeing people receive after performing the exercise.

    3     How do you choose the best physical activity for your exercise? There is no need for you to be an outstanding athlete or a long-distance runner to achieve stress relief. For instance, you can perform some aerobic exercise (有氧运动) such as jogging and dancing.     4     Doctors can help you develop an effective and safe exercise routine while taking into account your fitness level and the conditions you are suffering from.

Keep in mind that any kind of exercise will improve your fitness and reduce stress levels. You can also combine the activities till you have found the most enjoyable one. If you do not enjoy going near the water, never take swimming as a form of exercise. If the thoughts of running result in making you anxious, do not choose to train for a 5-kilometer race.     5    

A．Diet and exercise are proven equally important.

B．There are many ways to meet your exercise target.

C．One of the best strategies to reduce stress is exercise.

D．Both these things lead to a direct good effect on the brain.

E．Besides, it is also a good idea to consult your doctor for guidance.

F．It is necessary for you to make plans to form a healthy exercise habit.

G．Therefore, be sure to select an activity that you enjoy rather than fear.

2 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Have you ever wondered how people type Chinese characters? The answer lies in the wonderfully useful phonetic system     1     (call) pinyin. It's the most commonly used system for spelling out the Chinese sounds, and it uses the letters in the Latin alphabet that you are already familiar       2     .

Pinyin is     3     extremely useful tool and should be the foundation of your Chinese learning. Besides, it's not just for Chinese learners like yourself.     4     (actual), all native Chinese speakers know pinyin,     5     is the first thing Chinese children learn at school before learning characters. So even if you don't know Chinese characters, you can type in pinyin and make     6     (you)understood.

Every single sound that exists in Chinese can     7     (display) easily in a pinyin chart. Once you master these 409 sounds along with the tones, you'll have practically mastered the pronunciation of every single word in the Chinese language. We've also created a series of video     8     (lesson)with practice tools that enable you to record yourself and listen back to it to     9     (sure) that your pronunciation matches the examples. Combined with our Tone Pairs practice tool, you now have everything you need     10     (master)pinyin, tones, and Chinese pronunciation.

4 . Wealthy nations need to give as much as ten times current levels of funding to help developing countries adapt to climate change, the United Nations said in a report.

If developing nations can’t adjust to climate change, rich countries will also feel the consequences, says Inger Andersen, executive director of the United Nations Environment Programme (UNEP), which prepared the report. “The idea that you can have a wall around your state and somehow protect yourself is simply unrealistic,” Andersen says. The report comes as world leaders prepare to gather for a climate conference. Organizers hope to make people realize the growing gap between current levels of aid for climate adaptation and what they say is required as climate shocks get worse.

Climate adaptation refers to steps to better protect people against the consequences of climate change— for example, moving communities away from coastlines and other areas. But much of the climate focus from rich countries’ leaders has been on limiting global warming by encouraging countries to burn less coal, oil and gas to reduce the emissions of carbon dioxide and other greenhouse gases.

At the United Nations climate meeting in Glasgow, countries promised to double the amount of funding available for adaptation to developing countries by 2025. But even if nations succeed in that, it’d still be insufficient for the need. Besides, it’s often spent in ways that aren’t likely to be effective over time, the report said. Adaptation efforts tend to be narrow, focus on short-term needs and fail to take future risks into account, it said.

The risk is that countries will soon experience climate shocks to which they simply can’t adapt, Andersen says. Relocation (搬迁), arguably the most extreme and expensive form of adaptation, will soon become vital, according to Andersen. “In most low-lying coastal areas, planned relocation is the last strategy,” Andersen says. “The longer wealthy countries kick this can down the road, the higher the price in human lives.”

1. Why did the UNEP prepare the report?

A．To plan for the upcoming meeting.	B．To raise money for climate change.
C．To draw attention to climate adaptation.	D．To call on poor countries to build walls.

2. What is the main concern of rich countries about climate change?

A．Taking measures to reduce it.	B．Dealing with its consequences.
C．Funding developing countries.	D．Protecting people in poor countries.

3. What is the report’s attitude to the present use of the adaptation funding?

A．Positive.

B．Tolerant.

C．Indifferent.

D．Disapproving.

4. What do Andersen’s words mean in the last paragraph?

A．Rich countries will suffer more.	B．Humans will face a hard choice.
C．More people will have to relocate.	D．Living expenses will rise dramatically.

5 . Over the decades, computers have affected our lives to an astonishing degree. When the first modern computer was conceptualized and built in the 20th century, it was so large that it took up a whole room. Over time, the technology shrank. First, computers became small enough to sit on a desk and be brought into the home. Then, they were made lightweight and portable, giving us the laptop. Today, most people have something even smaller: a smartphone that can fit into a pocket.

Though that's as compact as most people are used to, computers and technology are getting even tinier! One of the tiniest forms of technology available today is the microbot. A microbot is a very tiny robot -a machine programmable by a computer—that is built to perform specific tasks. You might tend to refer to this as just a small robot, but the size and dimensions of microbots are actually quite precise. A microbot is less than one millimeter in width, approximately the size of the tip of a pencil. In comparison, a small robot, which can be up to 100 centimeters in width, would be absolutely large. If you think that microbots are as small as you can get, think again. Nanobots smaller than one micrometer exist, but these are so small that they aren't visible to the naked eye(肉眼).

Since microbots are so small, they are potentially very cheap. Scientists and engineers working to develop these microbots believe that they could be used to explore environments or areas that are too small or dangerous for people.

Because the computing power of one single microbot isn't that large, microbots could be moved and used in large groups. At the moment, the biggest barrier to the development of these tiny machines is figuring out how to power a robot that can only contain an extremely small battery.

1. What does the underlined word “shrank” in Paragraph I probably mean?

A．got more Automatic.	B．became smaller.
C．got wiser.	D．became larger.

2. What can we know about microbots?

A．They can be used to do risky tasks.	B．They are relatively expensive.
C．They can't be seen by the human eyes.	D．They aren't as precise as expected.

3. What is the key to the future development of the tiny robots?

A．Its function.	B．Its material.
C．Its battery power.	D．Its maintenance cost.

4. Which is the most suitable title for the text?

A．How Small the Technology Can Get	B．How Robots Change Our Future Lives
C．Why Human Beings Prefer Tiny Technology	D．Why Microbots Are Widely Used Worldwide

6 . The novel Restart was written by Gordon Korman and published in 2018. The book tells the story of Chase, a middle school student who loses his memory after an accident. At the beginning of the story, Chase gets knocked unconscious when he falls off a roof. When he wakes up, he can remember his name, but he doesn’t remember his past or his identity.

When Chase recovers and returns to school, he begins to learn about his own history through the reactions of the other students. As it turns out, Chase, once a star athlete, used to have fun hurting weaker students. Some people are afraid of him, some are angry with him, and some treat him like a hero. He finds that he doesn’t really like the people who used to be his best friends.

After his accident, Chase also has a different personality. He is no longer mean to other kids. However, everyone expects him to act the same as before. It takes time for the other students to learn to trust this new version of their old classmate. Each chapter is narrated (叙述) by a different character, so we get to hear every side of the story.

Gordon Korman has said that he enjoys writing for junior high school students because this is the age when kids begin to form their own opinions. In Restart, Korman addresses the themes of friendship, making mistakes, and getting a second chance. The novel explores the stories of a former bad guy and his victims, and gives readers a close look at the ways trust can be lost and rebuilt. The big picture comes together in little bits and pieces as each character offers their own details.

Everyone makes mistakes, and sometimes each of us would like to start over. In Restart, Korman shows us how to correct our mistakes and make it up to the people we have hurt.

1. What helps Chase rediscover his past?

A．His memory of the accident.	B．His fellow students’attitude towards him.
C．His status as a school hero.	D．His best friends’ account of his school life.

2. How is Restart unique in writing style?

A．It features vivid pictures.	B．It consists of obvious comparisons.
C．It is written from the view of an adult.	D．It contains narrations of different characters.

3. Which statement would Gordon Korman most likely agree with?

A．Friendship and trust can be regained.	B．Lost memories can be brought back.
C．Some mistakes can never be corrected.	D．High school is the best age to restart.

4. What is the text?

A．A news report.

B．A book review.

C．A fairy story.

D．A diary entry.

7 . The road trip is an iconic (标志性的) American family vacation experience. Here are some road trips you can enjoy.

College Tours

If you are mapping out a college tour road trip with your teen, pick a region like the Boston area. There you can visit a mix of options that are large and small, public and private, and a mix of easy-to-get-into and reach-for-the-stars schools. Make the most of your visits by researching hotel stays that give you a taste of campus culture.

Road to Hana

To do this trip right you'll need 10 to 12 hours. The Hana Highway runs along a winding road dotted with 59 (mostly one-way) bridges and there are often a lot of crowds. But patience is rewarded with a large number of Mother Nature's finest offerings. Remember to stop at the roadside stands selling fresh fruit and banana bread.

Mount Washington Auto Road

Little kids get a kick out of the simple pleasures of leaf-looking, making a fall road trip through New Englanda perfect choice for this age. Add a little extra fun for the grown-ups by planning a side trip for this scenic drive in New Hampshire. Less than eight miles long, the road climbs 4, 600 feet above sea level along narrow mountain roads.

Pacific Coast Highway

This one is for you, tired parents. This stretch of Highway I running up and down the California coastline is an incredibly popular road trip for its breathtaking scenery —just the thing to relax your tired selves while your little ones sleep lightly in the back seat. From late October through February, you can also take your kids to the Pismo Beach Monarch Butterfly Grove, where more than 10, 000 of the butterflies migrate (迁徙) each year.

1. What can a family do on a college tour?

8 . The printed book is back. Recent studies have shown that students retain more information when they read a hard-copy book compared to reading on a digital device.

E-books may come with a “suite of navigational tools,” but it turns out that the best navigational devices are your forefinger and thumb.     1     To think, all this time, those devices have just been just sitting there, dangling at the end of your arm.

    2     Old-fashioned books also have a search function, in which you turn back to the opening chapter to remind yourself of the hero’s surname. They even have a “bookmark system,” which uses a device called a “bookmark.”

Fans of the e-book point out that digital text is easy to annotate.    3     Traditional-book users have a similar system called a “pencil.” With it, favoured passages can be underlined and, if it’s a history book, pretentious comments can be written in the margin.

    4     In secondary school my physique was transformed by the daily need to carry science textbooks. For me and my fellow students, placing these weighty tomes in our backpacks would draw our shoulders back and our chests forward in a way that turned the school into the equivalent of a military parade ground.

    5     But for the moment, I find myself standing at attention, flexing my textbook-built shoulders and saluting their glorious return.

A．full bookshelf is at once a sound baffle and a store of knowledge.

B．Admittedly, e-books are lighter than paper volumes, but one must question whether this is really an advantage.

C．Also, the smell of old books in a second-hand bookshop is instantly evocative.

D．Fans of digital books may point out that e-readers have a handy “search” tool.

E．You can use them to flip the pages forward and backward.

F．Educational fads come and go, so maybe the shift back to traditional books won’t last.

G．Some devices even feature a little image of a pencil to guide the reader through the process.

9 . In India, a ______ uses his movements and music to control snakes.

A．performer

B．performance

C．stage

D．composition

10 . The more times you practice, ______ you will memorize something.
