    Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.

    It's always a good idea to wear your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.

    Now, think what will happen if you tie the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying. It will stay safe on the skateboard.

    Volvo,a famous carmaker, made the seat belts widely used in the 1950s.

    Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.

  1. (1) The passage mainly tells us ___________________.
    A . two important ways to keep safe in cars B . how air bags work to make cars safe C . how seat belts work to make cars safe D . why we must tie the egg to the skateboard
  2. (2) The writer gives the example of the egg to _______________.
    A . tell us that eggs are easy to break B . show how to wear a seat belt C . show why it's important to wear a seat belt in a car D . tell us what a skateboard is
  3. (3) Seat belts can make us safer because ___________________.
    A . we are interested in them B . they can stop us from hitting other cars C . they can help us stay safe on the seats D . they are made of strong materials
  4. (4) Air bags are important for cars because ___________________.
    A . they are made of plastic B . they can also help us keep safe in a car C . they can keep cars running slowly D . they are put in front of and next to the seats

    When people talk to each other, write letters or make phone calls, words of the spoken from or the written form can send any massage they want to pass on.

    But besides words, do you know any other ways you can use to communicate with people? Rich expressions on your face can be one of them. A smile on your face shows that you are happy. Tears in your eyes tell others that you are sad or excited. Body languages can do the same job. When you put your hand up in class,the teacher knows that you want to say something or you may have some questions to ask. You shake your head from side to side and people know you are saying "no" or refuse others' requirements. When you nod, people will understand that you are saying "yes" or agree to others' opinions or suggestions.

    Other forms can also carry different messages. For example, a sign at the bus stop gives passengers information on which bus to take. The flag language made by soldiers can pass different orders. Sound from the school bell tells the students and the teachers when to begin or end a class. A photographer can use the photos he has taken to tell others about what he thinks of the world around him. Music and films also convey the feelings and ideas of the musicians and the directors.

    So next time when you see a piece of art or listen to some music,take it as communication with its creator and try to get the meaning behind it.

  1. (1) When people want to use the words to communicate with others,they ______.
    A . write letters B . cry aloud C . keep silent D . smile friendly
  2. (2) According to the passage you just need to _______ if you agree to others' suggestions.
    A . close your eyes B . put up your hand   C . move your head up and down D . shake your head from side to side
  3. (3) Through a photo we may know _______.
    A . which bus can be taken B . What the orders mean for soldiers C . How the photographer finds the world D . when the students should have a class
  4. (4) The underline world convey probably means ______ in the passage.
    A . 掩饰 B . 传递 C . 克制 D . 爆发

    Where in the world can you take an hour's train ride, and pass a forest, a London street, a scene from the Wild West, and a burning building that never burns down? There's only one place, and that's Hollywood, in California. The scenes you see from the tourist train are film sets(布景) in the Universal Studios, one of the oldest and largest movie companies in the USA.

    A visit to Universal Studios brings back memories of great days of Hollywood, the films and the stars. But they are only memories. Hollywood isn't quite the same as it used to be. Costs have gone up and confidence has gone down. Movie-makers are afraid to spend their money on expensive new ideas. Instead, they repeat old ones.

    The film industry is changing fast. Teenagers still go out to the movies. The theatre is a good place to meet friends away from home. But older people mostly stay home to watch series, like Dynasty, and they have become as important to Hollywood as expensive movies. These "soap opera", as they are called, show rich, powerful families living in beautiful homes and wearing beautiful clothes. But the actors and actresses are nearly all middle-aged, like many of the people who watch them.

    Though it is soap operas that are keeping the film-makers of Hollywood in business, big films are still being made in America. But more and more of them are made outside Hollywood. New York is the most important new centre, but there are many others as well. Movie-makers have realized that they don't need Hollywood any more. Modern cameras and real houses take the place of expensively made copies in a studio. Other states, especially Florida and Texas, are working hard to take the film business away from California. They are offering better working conditions and lower cost.

    But Hollywood is fighting back. The state of California is trying hard to keep its best-known industry.

  1. (1) From the passage, we know Universal Studios is             .
    A . a very large park B . a busy London street C . a famous movie company D . an old Hollywood movie
  2. (2) The movie industry in California isn't as successful as before because             .
    A . young people don't go to movie theatres any more B . there is strong competition from other states C . its movie companies are in need of young stars D . the state hasn't put a development plan into action
  3. (3) What can we learn about "soap operas" from the passage?
    A . They are teenagers' favourites. B . They are much more expensive. C . They are less attractive. D . They are cheaper and easier to make.
  4. (4) The passage mainly tells us            .
    A . something about the film industry in the USA B . the importance of soap operas in Hollywood C . the good old days of Hollywood D . the film business in California

Many hundreds of years ago, a native (土著的) American chief named Shenandoah lived with his people in what is now the state of Virginia. Very l is known about Shenandoah, but the soft sound of his name was given to a river. The Shenandoah River still runs in a d valley (山谷) between the mountains in West Virginia, just as it did when Chief Shenandoah lived. There is an old story which tells how the river got its name.

A long time ago, many c before Europeans went to live in America, there was a great lake hidden in the mountains of Virginia. For hundreds of years, the native Americans lived near this lake, feeding on the f they caught in its clean waters. They often climbed up the mountains and set up camp there d their long hunts for food. In the evenings they sat near their camps and looked d at the beautiful lake.

On a clear, starry night you could see thousands of stars s and dancing on the water below. The native Americans loved this lake, and because they could see the stars in it they called the lake “Clear Daughter of the Stars.” In their l the word for this was “Shenandoah.”

One day there was a loud crashing sound at one end of the lake. The lake began to disappear. Its water rout of the vallev through a break (裂口) in the mountain side. The waters ran on and on until they j another river, which today is known as the Potomac.

At last, the lake was gone. In its place was only a river. It is this way today. The lake is gone, but the beautiful Shenandoah River runs on.

What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.

Escaping from a fire is a serious matter. Knowing what to do during a fire can save your life.

Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked(渗) into the room.

On a second or third floor, the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement(水泥) might end in injury. Bushes(灌木丛) and grass can help to break a fall.

    On Feb. 26th, 2020, when an Italian went to work with a mask to prevent COVID-19, his workmates thought he was "causing panic(恐慌)". You might wonder why the East and the West have different ideas about wearing masks.

In the West, people wear masks only when they get sick. People see masks as a tool(工具) to protect sick people and prevent the disease from spreading, so healthy people don't need to wear masks. Wearing masks in public easily makes them feel "worried" and "shy". They are "afraid of being looked at differently."

However, it's common in Asia. During the 2003 SARS epidemic, masks were widely used in China and East Asia. Many Chinese also like to wear masks to stay warm in winter or protect against air pollution.

In Japan, wearing masks shows your politeness when you get a cold or the flu. Some masks even have different colors and drawings. Young women may wear masks when they don't have their makeup on. Many pop stars in Asia also use masks to protect their privacy(隐私). This makes people in the East wear masks more often when epidemics break out(爆发).

But as the number of COVID-19 cases keeps on growing around the world, people in the West are changing. Many healthy people are starting to wear masks now to protect themselves.

  1. (1) If people in the West are _____, they may wear masks.
    A . worried B . unhealthy C . afraid D . shy
  2. (2) What does the underlined word "them" refer to in Paragraph 2?
    A . Japanese people B . Chinese people C . western people D . eastern people
  3. (3) Which of the followings is TRUE about the usage(用途) of masks in Japan?
    A . To keep warm in cold winter days. B . To be looked differently from others. C . To stay away from terrible air pollution. D . To show politeness when people get the flu.
  4. (4) Why are more and more western people starting to wear masks?
    A . Because they catch a cold easily. B . Because they don't want to cause panic. C . Because they don't have their makeup on. D . Because they know it's a good way to make themselves safe.
  5. (5) What's the best title for this passage?
    A . What does the mask mean? B . Don't be afraid of the illness. C . Let's fight against COVID-19. D . How can people protect their privacy?

A. This summer, even Americans are trying it.

B. Most people like the special taste it produces.

C. The way the dish is prepared also draws people's attention.

D. The strong smash makes the cucumbers different shapes and sizes.

E. Americans have expressed their opinions on the taste of this salad.

F. In China, people use garlic (蒜),vinegar (醋)and oil to make the cucumber tastier.

Smashed cucumber (拍黄瓜)salad is one of the most popular cold dishes in China. You can find the green dish anywhere from restaurants to homes.

According to The New York Times 9 smashed cucumber salad is  a"everywhere" in New York. Some restaurants have even added the dish to their menu.But American cooks are trying yogurt, honey, lemon and other common western ingredients.

Why is this dish becoming so popular?Smashed

cucumbers can hold onto tastes more than cucumbers which are cut into fixed shape and size. "Just changing the way you break down an ingredient... changes the way it feels and tastes. It's cool." said Danny Bowien, a cook at a New York restaurant.

The cook smashes fresh cucumbers with the flat side of a knife.Then other ingredients can be added. Also, it takes only five minutes to make the salad. Cook Julia Goldberg said it's really "satisfying".

The success of smashed cucumber salad abroad shows that we should try to fit into local conditions when spreading Chinese culture across the world, said The Beijing News.

Ways to be a great tourist

Being a tourist means you get to experience different cultures, beliefs, people, and food, but it also comes with a level of personal responsibility. Here are some ways to be a great tourist.

Smile and have fun.

This is the most important when you are on holiday. Leave your problems at home. It is free to smile. Have fun, and this is why you come here.

Ask questions.

Don't just sit there and wonder about things. Ask your guide.

If the guide does not have an answer, you can find the answer on the Internet.

We know you are on holiday and everybody wants to have fun stay up a bit late and have a few extra beers but please don't always be the last one on the coach. Your guide and fellow travellers won't be happy if they have to sit on the coach waiting for the one who is always late.

Be sensitive(善解人意的)

  Some countries are at war, some countries have a president you don't like and some countries do things in a different way than you are used to. Be open-minded about these things and get along well with your fellow travellers.

Reduce your waste.

Waste management can be a major issue when we are travelling and we as travellers often unknowingly pollute the environment.       For example, say no to plastic bags from shops. Instead, put your items in a backpack or a cloth bag.
 

A. Be on time.

B. Respect the locals

C. Nothing like a beautiful smile can raise your spirits.

D. You will be travelling with other tourists from other nations.

E. It's important to take action to help out the environment.

F. He/She has plenty of interesting facts and stories to share with you.

G . Saving electricity is important.

Online shopping, mobile payment and bike-sharing have left a deep impression on the 26-year-old Japanese man Haruki. He decided to write a book to share his 19-year e of living in China with the people of his country.

Haruki was b in Tokyo, Japan in 1995, and graduated from Xiamen University in 2019. Then he went back to Japan to work. He found many Japanese knew little about China and r it was necessary to open a window for the Japanese to understand the changes in China, so he decided to write a book to give the true information of China to the Japanese people.

He recalled that when his Japanese friends came to China to travel, they were surprised to see that bike-sharing was p in China. And people didn't take cash out to shop. I , they used digital w, such as Wechat Pay and Alipay.

The book was published in 2021. He hopes his book can provide Japanese readers with a look at the real China.

Have you ever seen pop-ups (弹出窗口) when you go online?

For example, Apps like Tiktok have the feature to prevent teenagers from watching videos for long and with the feature, they might only be allowed (watch) for 40 minutes. The videos that teenagers can watch are made sure to be safe and even educational. There are no advertisements and teenagers cannot pay any m for the videos.
