Trees are useful to man in three important ways.
The first important way is that they provide man with food, wood and other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It’s not easy for man to live on the earth without trees, either.
The second important way is that trees give us shade (阴凉). On a hot summer day, people are eager (渴望) to have a rest under a tree after they have a long walk. You can imagine how important the shade of a tree is to man and animals.
The third important way is that trees help to prevent droughts and floods (防止干旱和洪水). However, in many parts of the world, man doesn’t realize the third way. They cut trees down in large numbers. In the end they find that they have lost the best friends they had.

【推荐1】Americans love cars. They go everywhere in them. 85% of people in the US go to and from work by car. And most adults have driving licenses. Why does this car culture exist?
How it started
America’s love of cars started after the war when soldiers returned home from World War Π to rebuild their lives. They borrowed money from the government to buy houses and cars which became the symbols of status(地位). The more money they had, the bigger their cars were.
Making of roads
During the war, President Eisenhower noticed what good roads Germany had. He decided to build new four-lane(四车道)roads in America. He said if something happened suddenly, the two-lane roads wouldn’t be able to carry all the cars that would suddenly leave the cities. Car and oil companies liked his idea and building started.
Car lovers
Not just teenagers are crazy about cars. Some Americans love their cars so much that they paint their cars beautifully. These are called Art Cars. Every April there is an activity in Houston, Texas, where they show their cars.
Pollution
Cars have polluted the environment. American President Bush refused a worldwide law that is against pollution. Many countries were angry about it. Bush said he had to think of the American economy(经济)and all the American people that make money from cars. Factories say they want to make cars that pollute less. But others say making cars that pollute less will never be as good as having fewer cars.

【推荐3】If you live in Beijing, you may notice that the air these days is not as clean as it was during the summer. Fall and winter are the seasons with the worst air quality in northern China. It’s partly because people burn coal to heat their homes. Moreover, compared to the same period last year, higher temperatures, few windy days and little rainfall since September have made pollution worse, Xinhua reported.
To stop pollution from getting worse, Chinese government has made an action plan. It aims to control air pollution in the Beijing-Tianjin-Hebei region and nearby areas during the autumn and winter seasons, according to China Daily.
The plan sets higher goals. The average density (平均浓度) of PM 2.5 in the Beijing-Tianjin-Hebei region and nearby areas should drop by 4 percent from Oct 1, 2022 to March 31, 2023, according to the plan. Last year’s goal was 3 percent.
Also, the number of days with serious pollution should fall by 6 percent, the plan says.
This year’s plan has some highlights (亮点). It calls for “more scientific” production restriction (限制) in different industries.
The plan sorts factories or companies in 15 fields, including steelmaking and glass production, into three grades. Grade A companies are those that have very few emissions (排放). They will not have to restrict production. Grade B companies will face some restrictions. The plan will set the strictest restriction for Grade C companies.
This approach makes this year’s plan stand out from previous (以往的) ones, Chai Fahe, deputy director of the national Joint Research Center told China Daily.
1. The writer mainly tells us ________ in the first paragraph.A.the weather in northern China | B.how people heat their homes |
C.reasons for worse air pollution | D.the seasons in northern China |
A.3 percent | B.4 percent | C.6 percent | D.7 percent |
A.By drawing a mind map. | B.By answering a question. |

【推荐1】Although people everywhere seem to enjoy drinking coffee, they do not all have the same coffee culture. In Europe for example, coffee shops are common places for people to meet friends and to talk when they drink coffee. However, coffee shops were not as common in North America in the past. Although some people in North America went to coffee shops, most Americans liked to drink coffee in their homes with their friends better. The coffee culture in the USA changed(改变)when Starbucks coffee shops opened across the country.
The first Starbucks coffee shop opened in 1971 in Seattle, Washington, in the USA. It was a small coffee shop that roasted(烘焙)its own coffee beans(豆). The coffee sold well, and by 1981 there were three more Starbucks shops in Seattle.
Things really began to change for Starbucks in 1981. That year, Howard Schultz met the three men who ran(经营)Starbucks. He found that Starbucks ordered a large number of special coffee makers, and he really wanted to know why. Schultz went to Seattle to see what Starbucks did. In1982, the three Starbucks owners hired(雇用)Schultz as the Starbucks head of marketing.
In 1983, Schultz traveled to Italy. He was interested in the special feeling of coffee shops there. Back in the USA, Schultz created a comfortable feeling for Starbucks coffee shops, and people everywhere seemed to like it. With the help of Schultz, Starbucks became successful and famous. It began opening more coffee shops. Today there are more than 16, 000 Starbucks coffee shops around the world.
However, that does not mean Starbucks doesn’t have problems. For example, many Starbucks shops have closed over the past few years. In some places this is because there were too many coffee shops in one small place. In other places or countries, this is because the coffee culture there isn’t the same as Starbucks culture.

【推荐2】Hotels are no longer the first or the only choice for travelers in China to sleep in at night. A new type of accommodation(住宿)choice called bed-and-breakfast(B&B)is welcoming more visitors in China.
During this month’s Golden Week, bookings for the B&B in China grew by 400 percent from 2016, according to the B&B booking website tujia.com.
Starting in Europe, B&B is often a private family home. Travellers pay to stay overnight and have breakfast. In China, many B&Bs are in rural(农村的)areas and more about fun, experiences and new friendships, reported by China Daily.
“The meals are cooked by the host. Very often, vegetables are homegrown. Hosts and guests chat over the meal and play with the pets together,” Yu Minliang, a 23-year-old tourist from Shanghai, told China Daily.
However, as more B&Bs come out, the service sometimes may not be good enough. Some guests complained the soundproofing(隔音)was bad and the house was dirty.
To solve the problem, the first national industry standards were carried out on Oct.1. For example, every B&B should provide not more than 14 guest rooms and things like towels and sheets must be changed after every visitor.
The standards will help the B&B industry develop in a healthy and sustainable(可持续的)way, reported CNR(中国广播网).

【推荐1】Imagine this: you sit down and begin to eat a tasty tomato when, suddenly, it starts to scream (尖叫). While this thing will never really happen, a new study showed that plants can make sounds when they are stressed.
Researchers from Tel Aviv University in Israel did the study. They used ultrasonic microphones (超声波麦克风) to record the sounds of tomato plants in boxes.
Three groups of plants were listened to : One group wasn’t watered for five days, another group had the stems (茎) cut off, and the third group, was untouched. It turned out that the first two groups made sounds 30 to 50 times per hour at a frequency(频率) of 40 to 80 kilohertz, while the untouched group only made the sound once per hour. “When tomatoes are not stressed at all, they are very quiet,” Lilach Hadany from the team told CNN.
The researchers don’t know how the sounds are made, but they believe the noise comes from the breaking of air bubbles in the plants. This means the noise produced by the plants is not intentional (故意的) or a form of active communication.
Although there’s no evidence(证据) that plants can intentionally communicate, animals and insects may be “listening in” to benefit from the sound. For example, the sound can tell moth that the plant is under stress and not suitable (合适的) to lay eggs on. An animal that wants to eat a plant could also use the sounds to make decisions, according to Science Focus.
After the experiment, the researchers listened to other plants such as wheat (小麦), corn and grapevine, and found they also made more sounds when stressed. Researchers said the study can benefit farmers in the future, as they can better take care of the crops(庄稼) by “hearing” how plants feel.

【推荐3】Bananas are the perfect snack. Not only are they sweet and delicious, but they are easy to carry around, so you can take them anywhere. Best of all, bananas provide different things that the human body needs!
Bananas grow best in warm places that get lots of rain. They grow on plants that look like trees. The banana plant, however, is considered a herb rather than a tree because it doesn’t have a strong, woody stem(茎). The plants can grow as high as 30 feet. When they reach their full height, flowers grow out from the stem. These flowers produce bananas.
Two or three times each year, the plants produce fruit. The bananas grow together, which seem like “hands”. A hand is made up of 10 to 20 bananas. Growers sometimes call bananas “fingers”. Each bunch(丛)of bananas has about 15 hands, and so a whole bunch may have as many as 200 bananas and can weigh more than 100 pounds.
After about three months, the bananas are ready to be picked. At this point, they still aren’t the sunny yellow color of bananas. Farmers pick them when they’re green. They turn yellow along the way and are ready to be sold.
If you love bananas, you’ve got a lot of company(陪伴). Americans have been enjoying bananas since the first shipment(装载货物)arrived in the United States in 1876. Today, Americans eat more bananas than any other fruit. More bananas are sold than apples and grapes together. Every American eats over 26 pounds of bananas each year!
