"Yo ho…Hello…The mountain is green…, and I can sit for a while…"This clear loud song can be heard every morning. It is from the deep forest of the Wulingyuan scenic spot

Zhangjiajie, Hunan

Province. Who sings the song? It's Nie Jingming. This is how Nie calls for the wild macaques(猕猴), his good friends. 

Nie, 50 years old, was born into monkey training family. He has been taking care of wild macaques for more than 30 years. Every morning, he (sing) to them. After they hear (he)song, they jump to him from the rock walls and the forest. They know their good friend is waiting for them. 

Nie gets up early and comes home late every day. (look)for macaques, he walks around the forest. He also studies their living habits and feeds them (careful). Over time, Nie has developed a close relationship with them. And he (call) "King of Monkeys" by locals. Now, the Wulingyuan scenic spot has become a paradise(乐园) for wild macaques to live and reproduce(繁殖). It has also become Nie's second home.

Nie is like a parent, and all the macaques are like his children. "The macaques are

(love) and cute. They are not only good scenery, but also friends of local people and (tourist), "he said. "I will always take care of them, and I hope more people will join me. "

Not all penguins(企鹅) live in cold places. Like other penguins, African penguins spend most of the day feeding in the ocean, and that helps keep them cool. Their living place can get quite warm, but bare skin on their legs and around their eyes helps them stay cool. 

Most other penguins lay their eggs in the open. However, African penguins do it in a different way. Th e baby penguins stay in the holes for about three weeks. After that, they start going out and return to the hole to stay cool and stay away from dangerous animals. 

In the water, African penguins also have to keep away from other big sea life. 

The African penguin is in danger now. There are only about 14, 700 penguins left in the wild. 

Other problems include humans'picking penguin eggs for sale, competition with humans for fish and oil pollution in the ocean. 

A. They also stay in some cool places when they can. 

B. They dig holes to lay their eggs so that they are protected from the sun's heat(高温). 

C. One problem is that they are losing their homes. 

D. African penguins live in the south of Africa. 

E. On land, some animals such as dogs and cats will eat penguins. 

In the last 25 years, the number of monarch butterflies(帝王蝶) has gone down by hundreds of millions, according to the US Fish and Wildlife Service report. The black and orange butterflies face insecticides(杀虫剂), the habitat loss and the loss of milkweed(马利草)—the plant that monarchs lay eggs on and the caterpillars only eat. 

City people making a difference

The smaller number made Field Museum researchers in Chicago ask:What makes a successful monarch garden? Hasle, an ecologist(生态学家)at the Field Museum, and Karen Klinger, a geographer, are working to answer that question. 

Many stops along the monarchs' migratory(迁徙的) route are taking an all hands on deck(全员参与的) way to help out the butterfly, looking for more places for milkweed to grow. "We think, in one way, cities are

providing an important place for a lot of insects, "Hasle said. Although the project is still fairly new, there are already some findings.

According to the weekly reports participants sent, more successful gardens had more milkweed and blooming(盛开的) plants or much larger fields. But Klinger said one participant with a single plant watched eggs change all the way to chrysalises(蛹). So, she said, "You just need one plant. "

       ▲      

In 2020, during the second season of the study, the number of caterpillars dropped, even though the number of participants more than doubled. 

Chicago saw a hot, dry summer in 2020, which may have affected(影响) the health of the milkweed plants. In 2021, there was illegal logging (非法砍伐) in Mexico. Spring and summer weather conditions were hard for milkweed blossoms and egg development in the Southern US. All these affected the reproduction(繁殖) of the milkweed plants. 

Not giving up

"Now is the perfect time to start planning to plant some milkweed, "Hasle and Klinger said.

"The best thing to do is what you can do, "Hasle said. "One milkweed plant in a pot on your window board is doing something. Maybe it gives you something to look forward to during the boring winter in Chicago. "

①People are always interested in animals communication and scientists have done a lot of researches on this subject

② Most animals communicate by smell. Dogs are famous for this. When a dog walks outside, it learns about other dogs by smelling things. Dogs have helped the police for a long time, too. They can find missing people by using their fantastic sense of smell. Mice have an excellent sense of smell, too. Scientists even train them to find landmines. It is found that even ants use smell. They use smell to tell other ants where the food is. 

③Everyone has heard birds sing. Many other animals use sound to communicate. Frogs and insects communicate with sounds. Usually the "gentlemen"make sounds to invite the"ladies". Whales and elephants also use sound to communicate. These sounds can travel very far through water or ground. However, it is not possible for humans to hear some of the sounds. They are either too low or too high for us.

④ Animals also use body language to communicate. When a cat puts its ears back, it is a bit mad. When it sits with its tail around itself, it ishappy. When a dog puts its tail under its body, it is scared. When it wags its tail and opens its mouth, it is happy. 

National parks are large areas of public land. They give a safe home for local plants and animals. They help keep the air and water clean. Today, there are nearly 7, 000 national parks around the world. Forbes has listed 12of the most beautiful ones in the world that will surprise you with their amazing landscapes, geographic wonders and colorful plants and animals. 

The Grand Canyon(大峡谷) National Park of the US is one of the Seven Natural Wonders of the World. It is best known for its size and depth. It's 446 kilometers long, up to 29 kilometers wide and 1. 6 kilometers deep. The immensity of the canyon makes people think big. Taking a tour in the South Rim offers visitors the park's full views, while the North Rim shows beautiful wild flowers. 

If you love animals, you'll like the Serengeti National Park in Tanzania. The"Big Five"live here. They are the lion, African elephant, African leopard, black rhinoceros and African buffalo. The name "Big Five"came from the five animals that were the hardest to catch. Now they are what people most want to see in the wild. If you visit the park, you should never miss the migration of over 1.5 million wildebeests(角马) and over 200, 000 zebras every year. This is the most famous site of the park.

My friend Jack told me about a special test he had experienced in the first year of high school. 

It was a few minutes before the final1 exam. Some of the students seemed a little2 , though in fact everyone worked really hard at history as Mr. White was a strict teacher. When the bell rang, Mr. White came3 the exam papers in his hand. To our surprise, he didn't hand out the papers at once. 4 , he said, "I know how hard you have worked for this test and you all can do it well, so I'm willing to offer a B to anyone who would prefer not to take the test. "

Many students jumped up to thank Mr. White and5 the classroom. Mr. White looked at the rest of the students and said, "Does anyone else want to get a B? This is your last6 . " Two more decided to go.

Seven students including Jack remained. Mr. White then handed7 the papers. The students felt so surprised because there were only8 sentences typed on the paper: Congratulations! You have just9 an A in this test. Keep believing in yourself. 

I admired Jack for he had such a test and a good10 . I have never had a test like that11 I think it is a test any teacher could and should give their students. It is12 that the students who are not confident in themselves are usually B students or maybe even13 . The A students are those who believe in themselves. 

We should never14 unless we win the final success. Sir Edmund Hillary, the first person to reach the top of Qomolangma said, "It's not the mountain we conquer but15 . "

Have you ever offered a helping hand to those who are in trouble?

One day, two 1 were walking along the road to school when they saw an old woman carrying a large basket of pears. They thought the woman looked very 2. They went up to her and said, "Are you going to town? If you are, we will help carry your basket. "

"Thank you," 3 the woman. "You are very kind. You see I'm weak and ill. " Then she told them that she was now going to market to 4 the pears which grew on the only tree in her little garden.

"We are all going to the 5," said the boys. "Let us carry the basket. " And they took hold of it, one each side. They walked 6 with the heavy basket, but happily.

The other day, I saw a little girl stop and 7 a piece of banana peel(皮), which she threw into the dustbin (垃圾桶). "I wish 8 would throw that on the sidewalk," said she. "Someone may step on it and fall. "

Perhaps some may say that these are not 9 things. That is right. But such a little thing shows that you have a thoughtful mind and a kind heart. We must not wait for the 10 to do great things. We must begin with little things of love.
