1 . When a disaster happens, you might find yourself without water, gas or electricity. You might also need to leave your home right away. So you are supposed to plan for such bad situations. Here are some suggestions.
Choose two places for everyone to go to if it isn’t safe to return home. The first meeting place should be near your house. You can go there in an emergency like a fire. The second should be outside your neighborhood.
Get a family disaster kit (应急包) ready. It should include the things your family needs. It can help you survive at least for three days with bread, water, medicine and things like that. Put them in a bag so that you can carry it if you leave in a hurry. Do remember that different people have different needs.
| A．Practise your emergency plan. |
| B．Choose good places to avoid disasters. |
| C．Have a family meeting. |
| D．Choose a person outside your area to help. |
2 . How to be eco-friendly
If you'd love to be more eco-friendly but don't know where to begin, start with a few small changes. . Here are some suggestions for you to live an eco-friendly life
Turn off lights and unplug power strips (电源插板) that you're not using. This is an easy way to reduce energy use. Since some devices can still use energy even when they're turned off, turn off these power strips at night to completely cut off energy use. If you need to leave your computer or TV on, try setting it to the sleep mode instead of simply leaving it on.
Reduce your gas consumption and carbon emissions by walking, biking, or taking the bus. Keeping cars off the road in rush hours can also improve the air quality. If you do need to drive somewhere, ask friends if they'd like to carpool(拼车), so fewer cars are on the road.
Cutting back on plastics and waste.
Say no to unnecessary plastic straws(吸管), lids(盖子), and bags and stop using plastic wrap and plastic containers for food storage. Instead, you can use reusable water bottles made of sustainable material like glass, bamboo, and ceramic(陶瓷).
They add more oxygen to the air, which means less polluted air. If you don't have a green thumb, choose some plants that are rather easy to look after. “Lucky Bamboo” is especially good for that, since it demands nearly no attention. If possible, grow more than one plant.
| A．Considering growing a plant. |
| B．Using public transportation. |
| C．Lowering your energy. |
| D．Using items more than once. |
3 . The oceans occupy most of the Earth’s surface — about 70% — to the point of giving our planet its unmistakable colour. As such, they can tell the state of the Earth’s health: to observe them is to know where we stand.
In terms of climate, the warming and acidification of the oceans have harmful consequences for marine life and for land: there is of course the rise in water levels which threatens communities settling along the coasts. There is also a risk that is even more worrying since the oceans are no longer able to perform the climate regulation function that they have long fulfilled. As far as biodiversity (生物多样性) is concerned, the diagnosis is even more alarming.
We are well aware of these interacting crises, in particular thanks to the work of the Intergovernmental Oceanographic Commission of UNESCO. We also know where we must act. However, we still have to reflect matters and cooperate widely in order to manage the unavoidable and prevent the uncorrectable.
COVID-19 affords us this opportunity to come together and set up ambitious programmes of action. This is true for climate; it is true for biodiversity; it is also true for the oceans, as the United Nations Special Envoy for the Ocean, Peter Thomson, explained: “If there were ever a tide in human affairs that should be taken, this is it.”
It is indeed our responsibility to seize this moment. We must firstly learn more about the depths, which remain largely unknown to us and still hold many secrets that only we can reveal. Secondly, we must give free rein to imagination and innovation, which we need in order to deal with this worrying situation. This is why we have made innovation the theme of 2020 World Oceans Day. We must also seize this moment to sound the alarm, perhaps more widely than we have done so far, because no technical solution can replace a widespread, personal understanding of the threats to the oceans, their mysteries and their beauty.
1. What has made people worried about the oceans according to Paragraph 2?2. What does the underlined phrase “give free rein to” probably mean?
| A．Place a restriction on. | B．Be in possession of. |
| C．Give complete freedom to. | D．Come up with. |
Strange things were happening in the countryside of northeast Hebei. For three days the water in the village wells rose and fell, rose and fell. Farmers noticed that the well walls had deep cracks in them. A smelly gas came out of the cracks. In the farmyards, the chickens and even the pigs were too nervous to eat. Mice ran out of the fields looking for places to hide. Fish jumped out of their bowls and ponds. At about 3:00 am on July 28, 1976, some people saw bright lights in the sky. The sound of planes could be heard outside the city of Tangshan even when no planes were in the sky. In the city, the water pipes in some buildings cracked and burst. But the one million people of the city, who thought little of these events, were asleep as usual that night.
Answer:
Environment means all the
The components of nature are made use of by the human beings
8 . A giant dam was built many years ago to control the Colorado River in the U.S. This dam was built to protect the land and houses around the river.
This huge dam is in the Black Canyon. It is possible to drive a car from one side of the river to the other on a road, which is on the top of the dam. This dam is so big that there is an elevator inside. The elevator goes down forty-four stories from the road to the bottom. There is enough concrete in this dam to build a highway from New York to San Francisco. Thousands of people worked on this dam for five years.
This huge dam was called Boulder Dam when it was finished in 1936.Later it was renamed Hoover Dam in honor of a president of the United States. Hoover Dam, one of the highest dams in the world, is situated between the states of Arizona and Nevada.
Q：Hoover Dam lies ______.
| A．between Arizona and Nevada |
| B．in the Black Canyon |
| C．between New York and San Francisco |
| D．both A and B |
1. Pet-keeping is a time-honored tradition. One of the reasons for people to raise dogs or cows was usefulness. While people in the past hunted animals and kept them in their backyards, the civilised man today is less cruel towards them and is less exploitative(利用的).
2. We keep animals as pets because they are attractive. We all have the urge to possess something that has aesthetic（审美的）value, and this is why we treasure paintings or fine furniture. Keeping pets is one form of this urge. A Siamese cat in the house can be a decorative object. Pets are playful animals and they amuse us. A little rabbit amuses us by its playful and lively runs.
3. Many parents find it helpful to have pets in the house for their children. Having pets is an excellent way of developing in children the love of animals and responsibility. Children get the opportunity to take on full responsibility for another creature’s life. It will be an educational experience for a child to watch the natural life cycle of an animal. There are psychological benefits for children. Pets are welcome friends for children who are lonely. Pets are excellent companions. Keeping pets means giving love and being loved. We find comfort in giving care and receiving care in return. We get pleasure from their appearance and their behavior.
4. As more people move into apartments, there are limitations on keeping of animals like dogs and monkeys. Therefore, caged animals have increased in popularity. Birds fall into this group. We keep them for their beautiful songs and feathers. Fish-keeping is a widespread hobby and the keeper can observe their behavior in the glass tank and study its entire life cycle. The cat is a fine house pet and it fits neatly into human habitation(居住地) without requiring its own cage. They are wonderful hunters, if there are rats around.
5. Pets satisfy man’s desire to care for a bit of nature. The pet owner has the responsibility for supplying those needs that nature provides. Pets are amusing and entertaining, but we are in a way doing animals harm by making them live in a human environment. Are we not enslaving(奴役)them?
| A．Adults keep pets with their children. |
| B．Pet-keeping has a very long history. |
| C．Pet-keeping may do harm to animals. |
| D．People keeps pets for their aesthetic need. |
| E．Caged pets become increasingly popular. |
| F．Pet-keeping is helpful for children’s growth. |
10 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
What is the text mainly about?
| A．Wildlife research in the United States. |
| B．Plant diversity in the Yellowstone area. |
| C．The conflict between farmers and gray wolves. |
| D．The reintroduction of wolves to Yellowstone Park. |
