【推荐2】Bats are the only mammals (哺乳动物) that can truly fly. They play a very important role in ecosystems (生态系统) around the world. They help kill pests for farmers. They also help ensure that rainforests stay healthy. Bats face many dangers though. This means ecosystems across the globe are endangered too.
There are more than 1,000 groups of bats. The most of bats are insectivores. This means that insects make up most of their diet. There are also bats that are nectar-eaters and fruit-eaters. A small number of bat groups are blood-eaters.
Nectar-eating bats and fruit-eating bats play an important role in desert and tropical (热带的) ecosystems. They are considered a “keystone group”. This means they help ensure a rich diversity (多样性) of plant life and food for other animals. Nectar-eating bats help pollinate (授粉) plants in these environments. Fruit-eating bats help spread seeds in their rainforest environment. They also help restore (修复) rainforests that have been cut down by spreading seeds over large areas. Bats are sometimes called the “farmers of the tropics.”
Bats that are insectivores help farmers around the world with pest control. They eat insects that can damage agricultural crops (农作物). One pest that bats like to eat is called the corn earworm moth. This type of moth causes about $1 billion a year in crop damage.
Bats can eat large amounts of insects at night. For example, the famous bat group that lives in Austin, Texas eats between 10,000 and 20,000 pounds of insects each night. The Austin bat group is made up of 1.5 million Mexican free-tailed bats. They rest under the Congress Avenue Bridge in downtown Austin during the summer months. The number of the bats is so large in North America that many tourists come to watch them leave their resting place in the evening.
Resting place loss is the biggest threat facing bats worldwide. Bats in North America are also in danger because of white-nose syndrome. This disease affects bats while they are living during the winter. White-nose syndrome is a deadly wildlife disease. Millions of bats in North America have died from the disease since it was first recognized exactly in 2006.
Bats around the world are facing many other threats unknown by us yet.Large numbers of bat groups are in danger of disappearing forever. Scientists believe that almost 80 groups of bats are endangered. They also believe that over 900 groups of bats will become endangered. Conservation organizations are working hard to save bats around the world. Although some people fear bats, they are an important part of the natural world. Protecting bats helps protect the environment.

【推荐3】How would you like to live underground? Many families in the town of Coober Pedy, Australia, do just that. Their houses, called dugouts (防空洞), are carved (挖) out of the earth. They are similar to common houses. They have kitchens, bedrooms，and living rooms, but they have few windows. Most of the light in the houses comes from lamps and overhead lights instead of direct sunlight.
People in the town build dugouts because of where they live. Coober Pedy is in a desert in southern Australia. The temperature can climb as high as 50℃ in summer. It can drop as low as zero in winter. Dust storms and swarms of flies (苍蝇) can make life miserable. Underground, though, it is always a comfortable 23℃. People don’t even need fans.
Why would people want to live in such a place? Coober Pedy is an opal-mining (猫眼石矿) town. Opals are colourful stones used for jewellery. The mines (矿) in Coober Pedy produce most of the world’s opals. Early settlers (定居者) there realized that they could avoid the harsh temperatures by building their homes underground. Today almost half of the 3, 500 people in the town live in dugouts. Restaurants, schools and other buildings are also underground. People enjoy their lives “down under”.

【推荐2】These days, short videos have gotten millions of views (关注) online. Many people create and share short videos on popular video apps like Douyin and Kuaishou. You can even add music and special effects to your videos. The videos can last 15 seconds to a few minutes long. They show people doing activities like cooking, exercising, singing and so on.
Teenagers especially enjoy these videos. More than 50 percent of students in Grade 7 and Grade 8 said they enjoyed watching these short videos. About 47 percent have uploaded (上传) their own videos, according to a recent survey.
The videos let teenagers see funny and exciting things they seldom see. Many teens like to share the fun things they do with others as well. For example, a 12-year-old girl named Xiao Qianyu has uploaded videos showing her learning jazz dance. This has won her many fans.
But the videos can also cause trouble. Some students watch them too often and they don’t have enough time to study. At the same time, some vulgar videos are harmful for teenagers.
To deal with this problem, Douyin added a new function (功能) in April, 2018. It locks the app if students use the app for over two hours a day. In the same month, the government asked companies to control these apps and get rid of bad videos.

【推荐3】If someone asks you to choose a great living thing, mushrooms probably won’t be your first answer. However, scientists recently have discovered that mushrooms can do more than you think.
First of all, they can control the weather. Scientists have found that mushrooms have the unique (独特的) ability to create rain. This happens because of the way they release their spores (孢子). As water collects on the surface of a mushroom, it gets stuck in these spores. Later, when the spores are set free, they get together with dust in the air to create clouds and rain.
Another fascinating thing about mushrooms is just how many kinds of them there are. It’s believed that there may be more than five million different kinds of mushrooms. What’s more, scientists believe that they’ve only found 10% of them.
Lastly, mushrooms could have an influence on the environment. We all know that plants can take in CO₂. However, when they die, CO₂ goes back into the air again. Mushrooms, on the other hand, keep this kind of greenhouse gas underground, which helps keep the air and environment clean. It shows that no matter how small mushrooms are, they can do more than we can see.

Mr. Smith was the manager of a small office in London. He lived in the countryside and came up to work by train. He liked walking from the station to his office unless it was raining, because it gave him some exercise.
It was a sunny day and Mr. Smith was walking along the street happily. Suddenly a stranger stopped him and said to him, “You may not remember me, sir, but seven years ago I came to London without a penny in my pockets, I stopped you in this street and asked you to lend me some money, and you lent me £ 5, because you said you were willing to take a chance so as to give a man a start on the way to success.”

When he was in school, his teacher asked him to write a paper about what he wanted to be and do when he grew up. He wrote a seven-page paper talking about his dream of having a horse farm one day. He even drew a picture of a horse farm in the paper.
The next day he handed it to his teacher. Two days later, he got his paper back. On the front page was a large red “F” with some words “See me after class.” And the boy did and asked his teacher, “ Why did I get an F?” The teacher said, “This dream will not come true for a young boy like you. Owning a horse farm needs a lot of money. You have to buy the land. You have to pay for a lot of things. There is no way you could ever do it.” Then the teacher added,“ If you write this paper again with a simple dream, I will give you a good grade.”
After school he thought about it hard. At last, he decided to hand in the same paper, making no changes at all. He wrote, “You can keep the F and I’ll keep my dream.”

【推荐3】Smile Train is a charity ( 慈善团体) that helps the millions of children around the world, who suffer from a facial defect（ 缺 陷 ）. The defect happens when a baby’s top lip or mouth doesn’t form properly before birth. Eating and drinking is very difficult for these babies. The charity provides free operations, which give these children a new smile, and with it, new hope and a new beginning.
Children with the defect need all the help. Although many sufferers are accepted by their families, sadly, others are not. In some countries, children with this defect are often abandoned at birth because their parents feel ashamed（ 尴 尬 ）of them or cannot afford the operations. The good news is that the operation is not difficult. It takes less than an hour and costs the family nothing. The charity raises money and finds the right medical volunteers to perform the operations.
A Smile Train doctor from the UK said, “Each child who has the operation is given a second chance at life. After years of staying at home, the children can finally go to school and be happy. Every year I perform hundreds of operations free of cost through Smile Train. Some of the stories I have heard are quite surprising.
One newborn baby girl was found abandoned on a train. Luckily for her, she was found and adopted（收养）by a passenger. This lady then heard about Smile Train and brought the baby to our hospital. I did the operation and gave hope to the family. Experienced doctors like me share our skills with local doctors. In this way make sure that these operations will always be available（可获得的）.”
