Hey, we are bats (蝙蝠)! We are the only flying mammals(哺乳动物) in the world. Many of you are now afraid of us, aren’t you? There is novel coronavirus (新冠) outbreak (爆发) all over the word. Many people say the virus(病毒) comes from us and they think we are the killers! We are not happy about this!
We bat live on the earth for about 50 million years. How about you humans? We have super immunity (免疫力), so we can live with many viruses.
Let us tell you: some of these viruses can easily kill you! Well, it’s true that we are very dangerous. We know this, so we try to keep away from you. We go out only at night when most of you are sleeping. But some of you forget how dangerous we are. You kill our brothers and sisters and eat them. The viruses in the bat meat(肉) can kill these people. How foolish(愚蠢) they are! I hope you will learn a lesson from the coronavirus outbreak. Don’t eat or kill wild animals! Please!

【推荐1】Botswana said it planned to send 20,000 elephants to Germany. “This is not a joke,” the president of Botswana said.
Botswana is a country in Africa. It has about 130,000 elephants, the most in Africa. These big animals often go to towns to find food and water. They can eat crops (庄稼) in farms, destroy houses and sometimes even step on people.
To help with the problem of too many elephants, Botswana lets people hunt them, but only up to 400 elephants each year. People can also take home their “trophies (战利品)”, such as the tusks (象牙). But Germany doesn’t like this idea. Some people there think it’s bad for the Earth.
In response to Germany, Botswana had a funny plan. They planned to send some elephants to Germany, so people there could see what it’s like to have lots of playful elephants running around!
Think in a different way: Perhaps we can work together to find a smarter and kinder way to help deal with the playful elephants.
● Make fences (栅栏) with beehives (蜂巢) or chili peppers (辣椒) around towns. Elephants don’t like these two things.
● Use satellites (卫星) and AI to track (追踪) elephants.
● Build special paths for elephants.
Fun facts about African elephants:
● They are the largest animals on land.
● There are about 415,000 of them in the wild.
● They can live up to 70 years.
● They have larger ears than those Asian elephants.

A man found a bird with a blue medical face mask wrapped(被缠绕的)under its beak(鸟嘴)and wing. The mask appeared to have blown into the tree. Where is the mask from?
During the corona virus(新冠病毒), we can find the masks on the streets, in the shopping carts, in the parking lots, on the beaches and green spaces around the world. The sanitation workers try to pick them up. However, those that are not picked up can be caught by a gust(一阵)of wind or washed down in the drains(下水道). Many of them may end up in the ocean and waterways.
What will happen if we throw away the masks everywhere? The materials that the masks are made from can’t be recycled. The bright colors of masks can be mistaken as food by birds. If these are littered in the river or sea, the fish, turtles and the marine mammals(哺乳动物)may be at risk of severe injuries and death dues to them. They confuse(混淆)them for real food. This will cause their death. There will be many other different wildlife species that are threatened(威胁)by the pollution.
In a word, we shouldn’t throw away our masks everywhere. This bird is an innocent victim(无辜受害者)of human beings’ carelessness. We must protect those animals who can’t speak for themselves. We must continue to spread awareness and educate our communities before it is too late.

【推荐3】One cold Sunday, Mariko and her dad were walking to the store.
“I don’t like winter,” said Mariko.
Dad waved (挥手) at their neighbour. “I know Mr Hill hopes spring comes, too.”
Mr Hill was sitting and enjoying the sun in his garden. He waved, and Mariko waved back.
“Mr Hill loves his garden,” said Mariko. Mr Hill had the most beautiful spring flower garden. It was full of daffodils (黄水仙).
Dad said, “Yes, he does. And because he is old, it is hard for him to go outside in winter.”
At the store, Mariko helped Dad choose milk, bread and vegetables.
“You may choose something for yourself, Mariko,” said Dad.
At first Mariko thought apples would taste good. But then something else caught her eye, “Oh, Dad, look, daffodils!”
“Is that something you want?” asked Dad.
“Yes!” Mariko said happily.
Mariko couldn’t stop looking at her daffodils all the way home. But when she got to Mr Hill’s house, she stopped, “Maybe I could...”

【推荐1】①Have you ever been to the Dead Sea, one of the most famous natural wonders in the world? Have you ever thought about why it is called Dead Sea? Does it hold life? Can people swim there? With all these questions in your mind, let’s know something about it!
②The Dead Sea is actually a lake in the Middle East. At four hundred meters below sea level, it’s the lowest point on Earth. It lies between the borders of Jordan, Israel, and the West Bank. It’s about 80 kilometers long, 11 kilometers wide at its widest point, and 377 meters deep at its deepest. The lake is surrounded by hot, dry desert on all sides.
③Since it’s in a hot desert, water evaporates (蒸发) faster than the lake is refilled. And the area is lower than all the land around, the water can never flow back out, it can only evaporate. And that’s what happens—water continually evaporates. In fact, so much water is evaporating from the Dead Sea, it often looks like there’s a cloud of fog hanging over the lake. Anyway, as the water evaporates, it leaves behind the salt and minerals (矿物质). The water in the Dead Sea is almost six times saltier than ocean water!
④Because the Dead Sea is so salty, almost nothing can live there, except for bacteria and one type of algae. Any fish or freshwater animal that gets washed into the lake dies almost immediately. And the shores are covered in thick salt crystals (结晶), so animals can’t even live near the lake either. That’s why it’s called Dead Sea.
⑤Since it’s so salty, why do people go there to cover themselves from head to toe with its mud? Actually, those minerals are supposed to be really good for your skin. No wonder lots of spas and health resorts have been built in the area. Though the water in the Dead Sea is so salty, it is totally safe for people. You can even go swimming there if you want, although it’s pretty hard to swim because all that salt makes it much easier to float! It’s really unbelievable.
⑥Want to know more about it? Just explore it yourself!
1. Why does the writer use four questions in the beginning?A.To encourage readers to travel. |

You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters(厘米)from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on(反射)the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1)Rest your wrists on something. 2)Keep your elbows(肘)at the same height as the keyboard. 3)Stop sometimes and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel(平行)to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.
Enjoy your computer, but use it safely.

What makes you cry? Do you cry when you are moved by a sad movie, waving a loved one off, or having to get away from family? They can all cause tears to roll down our faces.
Tears running down from your face can be embarrassing. But it seems to be a natural reaction when we get sad or upset.
A study in the UK found that women cry 72 times a year. This was more than men. Adam Rutherford, the researcher, says that the result has been pretty similar in recent studies.
One place where we experience emotional outbursts is in the workplace.
But crying in the office or elsewhere can be an effective way to relieve stress. It can actually make you feel better.
A.Emotions can run high in this place. |
B.Also, it clears the bad feelings you’ve had. |
C.We all cry sometimes, but is that a good thing? |
D.People reach their breaking point in different ways. |
E.But does this mean men don’t get as upset as women? |

【推荐1】Now, more and more cities are facing problems, such as high housing costs, pollution and crime. Let’s see what people in Hyderabad, India and in Sao Paulo, Brazil do to solve (解决) the problems.
Hyderabad, India
To improve people’s lives, Hyderabad is planting more and more trees. The city is even creating greener buildings that use less water and less electricity for power. Adding green to a city has a number of advantages. For example, trees make the air cleaner. In Hyderabad, streets were grey and dirty in the past. However, today they are filled with trees and flowers, making the city cleaner and more colourful. Green areas also give people places to relax or exercise. A study in the USA shows an interesting thing: the greener a neighborhood is, the less crime there is.
Sao Paulo, Brazil
Many people work in the centre of Sao Paulo, but they don’t live there. They’ve spread out to neighborhoods outside the city because housing is cheaper. Every day, these people travel into the city, and traffic is very heavy. City planners are using different ways to deal with (处理) the problem. First, they are building better subways. Another goal is to make it cheaper for people to live in the downtown area (中心区). Doing this will reduce traffic and pollution in the city.
1. What does the underlined word “greener” mean?A.Taller. | B.Easier. |
C.Better for the environment. | D.More brightly coloured. |
A.It helps people work better. | B.It makes the city cleaner. |
C.It reduces crime. | D.It makes it easier to exercise. |

C.A lot of people are moving out of the city. |

【推荐2】 “How are you?” is a nice question. It’s a friendly way that people in the USA greet each other. But when a person says “How are you?”, he hopes to hear the answer “Fine,” even if (即使) the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question, and “Fine.” isn’t really an answer. They are common (常见的) ways of saying “Hello” and “Hi” .
Sometimes people also don’t say exactly (确切地) what they mean. For example, when someone asks, “Do you agree?” the other person may be thinking, “No, I don’t agree. I think you are wrong.” But it isn’t very polite, so they may say, “I’m not so sure.” It’s a nice way to say that you don’t agree with someone.
It’s interesting when people want to finish talking. For example, when a person wants to finish talking with other people on the phone, he may say “I have to go now.” Sometimes he gives an excuse (借口), for example, “Someone is knocking at the door”. The excuse may be real, or it may not be. It’s a polite way to finish talking and it doesn’t hurt the other person’s feelings. People don’t always say exactly what they are thinking. And it’s a part of the game of language.
1. What can we learn from paragraph 1?A.It’s not a friendly way to say “Hello” or “Hi” |
B. “How are you?” is another way to say “Hello” . |
C. “Fine” is the only answer to the question “How are you?” |

【推荐3】Brazil is the biggest country with the largest population in South America. It is one of the world’s rising powers(新兴力量).
Brazil has been a big farming country for the last 10 years. It produces a third of all coffee in the world, which makes the country the biggest coffee producer in the world.
Tourism is also important in Brazil. A large number of foreign visitors come to Brazil every year.

The unique scenery gives its people special characteristics. Brazilians are easygoing and passionate. We can see that from their famous Carnival(狂欢节). People call it the “world’s biggest party”. Although most Brazilians are from different races(种族), including Amerindians(美洲印第安人), European settlers, and Africans, they get along well with each other.
It’s the different races that offer Brazil a very rich culture. From samba(桑巴)and carnivals to food and music. African culture is everywhere in Brazil. Sao Paulo(圣保罗)is home to the biggest Japanese immigrant community(移民团体)in the world. People can see Japanese style restaurants and supermarkets lining the streets. As a result, many visitors are attracted to Brazil every year.
