In recent years, more and more people have realized the 32 of ecological balance. We are now 33 to keep nature in balance.First, there are strict rules to 34 pollution. Factories must clean their waste before it goes into the air or water. Second, the government has built nature parks to protect animals and plants. In these areas, people cannot hunt, and many trees are 35 to grow new forests. These steps help wildlife live 36 .Tourists can help too! They are asked to travel in a green way. In beautiful places, signs tell tourists not to throw 37 or scare animals. Some parks only allow a certain number of 38 to visit each day. This helps protect nature.Because of these actions, our 39 is getting better. The air is fresher, the water is 40 , and some endangered animals are coming back.

The corals themselves are tiny organisms that build up over time to form vast structures. These structures provide a home for countless species of fish, sea turtles, and other marine creatures.The colours of the coral reefs are breathtaking. There are vivid reds, brilliant blues, sunny yellows, and every shade in between. The fish that swim among the corals add to the beauty, with their own unique colours and patterns. Some are striped, some are spotted, and others are a single solid colour. It's like a living masterpiece, constantly changing and developing.However, coral reefs are in danger. Rising sea temperatures, pollution, and overfishing are all threatening their existence. Many coral reefs around the world have already been damaged or destroyed. We need to take action to protect these precious ecosystems. By reducing our carbon footprint, supporting conservation efforts, and being more mindful of our waste, we can help ensure that the beauty of the coral reefs remains for future generations to enjoy.( )59. What kind of creatures live in the coral reefs?A. Only fish.B. Only sea turtles.C. Marine creatures.D. Land animals.( )60. What is NOT mentioned as a threat to coral reefs?A. Earthquakes.B.

They decided to feed them green vegetables like lettuce and cabbage. Ron Mezich, an expert, said,“We' re making a difference.” By the end of 2021, they had served up more than193,000 pounds of lettuce to hungry manatees.Manatees are huge sea animals and they only eat seagrass and other plants that live in the sea. That's one reason why they' re sometimes called“sea cows”.Since 1967, Florida's manatees have been on the US government's list of endangered animals. Most dangers to manatees come from humans. One of the biggest problems facing the animals is boats. Thousands of manatees were hit or killed by boats. At one point, there were only about 2,000 manatees left in Florida. With protection, the number increased. In 2016, there were more than 6,000 manatees.However, as seagrass began to disappear, the number of manatees kept going down again. Warming seas with polluted water have created a huge growth of algae(藻) on the ocean's surface. The algae block(阻挡) the sunlight, so the seagrass dies. In Indian River Lagoon, where manatees often go in the winter, about 90%of the seagrass beds there have died off. Florida will work to help restore(恢复)seagrass beds. But that will take time. Scientists still worry that more manatees could die in the coming years.( )62. Manatees are sometimes called“sea cows” because .A. they are as big as cowsB. they can swim like cowsC. they have tails like cowsD. they feed on plants like cows( )63.新考法·图文转换 How has the number of manatees changed over years?( )64.新考法·逻辑排序 Which shows the correct order of the causes of manatees'death after 2016?A. sea pollution →growth of algae →death of seagrass →death of manateesB. growth of algae →sea pollution →death of seagrass →death of manateesC. sea pollution →death of seagrass →growth of algae →death of manateesD. growth of algae →death of seagrass → se a pollution →death of manatees( )65. Which is the best title for this passage?A. The Growth of Algae in OceansB. The Death of Seagrass in FloridaC. Manatees: The“Sea Cows” of FloridaD. Saving Florida's Manatees from Hunger DThere are different kinds of plants and animals on the earth and they get their food in different ways. Food chains are just used to show who eats what in a very simple way.Food ChainsHere are some examples of food chains.A garden food chain might look like this:Humans can also be part of a food chain. A farm food chain could look like this:A food chain shows how plants and animals are connected with each other based on the foods they eat. Food chains are different depending on the habitat. Ahabitat is the scientific name for a place where animals and plants live. Habitats can be very different from each other, so a garden food chain would be very different from a farm food chain.Food chains usually start with a green plant, such as grass or a tree. This is because plants can directly change sunlight into energy that they can use for themselves. These plants are called“producers”, and they create or produce their own food. They use this food to grow leaves, flowers, fruit and seeds.Food Chai n Disruption(中断)When the balance of a food chain is broken, it may result in a bad situation. An example is overfishing. Over the years, humans have been catching too many fish at a high speed leaving not enough to keep a healthy population. Because of this, other animals such as turtles are endangered. So, we should make sure our activities don't harm the ecosystem.( )66. How does the writer explain“food chains”?A. By telling stories.B. By asking questions.C. By listing numbers.D. By giving examples.( )67. What can be best put in“ ▲ ” in the second food chain?A. chickensB. treesC. sunlightD. flowers( )68. What can we know from the passage?A. Food chains usually start with human beings.B. Different habitats lead to different food chains.C. A garden food chain may be the same as a forest food chain.D. Plants are called“producers” because they produce food for others.EIn Shanxi, an old man walks along Yuncheng Salt Lake with his dog every day when the sun rises. He is Ma Hongyi, who lives in a village just about 200 metres from the lake.Ma still remembers the winter day in 2014 when he first saw two big pink birds in the water. “I never saw such pretty birds. They were even taller than me, with long wings,” Ma said, holding his arms out wide.A young man told him the birds were flamingos(火烈鸟). It's hard to see them inChina and they have been vulnerable animals.From the first day he saw the flamingos, Ma started to work as a volunteer to patrol(巡逻 ) the lake area. Every day, he walked around the lake to stop people from disturbing(打扰) the birds. He told people not to get close to them and not to throw waste into the lake. “The birds like the nice environment here,” Ma said.“I’ ll do my best to protect the lake so that they can come here every year.” After patrolling the lake for over four years, Ma took a job with the local government to help with wildlife protection in 2019.“The lake environment is getting better and better,” Ma said. “Some of the flamingos are my old friends.”( )69.

To keep himself busy every day.B. To get a job from the government.C. To make friends with the flamingos.D.

How would you feel? Disappointed?Angry? Sad? At this moment you realize people, plants, and animals are all connected. We need each other to live, and bees are one of the best examples of this connection.Bees are very hard-working animals, and their greatest work is pollination(传粉). On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen(花粉) with them. This action helps plants grow. In fact,without their work, about 80 percent of the plants in the world cannot grow.Bees are also one of the most interesting animals in the world. For example,they work hard with each other to make their homes. In order to store honey,they make honeycombs(蜂窝 ). Another interesting thing about bees is how they communicate. When a bee finds new food, it uses a dance to tell the others where and how far away the food is.Bees play an important part in the ecosystem of our planet. However, the number of bees is dropping, and scientists are worried. Bees need our help, and there is a lot we can do. Think about what you can do to protect one of the most amazing animals on earth.73. What will happen without bees' work?(不超过 15个词) 74. What are bees like according to the text?(不超过5个词) 75.
