1 . The early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood (成年). From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes, and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. Then, it moves slowly to the sea.

The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.

As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece of plastic (塑料) in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.

Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.

2 . You'll need to take a deep breath before hearing this news. An astonishing 93% of kids around the world live in environments with air pollution levels that are damaging their health, according to a new report by WHO.

Air pollution is to blame for the deaths of 543,000 kids under 5 in 2016, with more than one in four deaths of children under five years old being related to environmental issues. Exposure (暴露)to air pollution can damage the health of kids in a variety of ways, either causing or being associated with everything from low birth weight to childhood obesity and so on.

"The large toll of disease and death revealed (揭示)by these new data should result in an urgent call to action for the global community especially for those in the health department WHO stated. “ Strong action to reduce exposure to air pollution offers an opportunity to protect the health of children. " The report stressed that health experts should communicate with families , communities and policy-makers about the serious risks of air pollution exposure. " Although more researches into how air pollution affects children's health will continue to be valuable, there is already evidence to justify strong, swift action to prevent the damage it clearly produces," WHO added.

Disease caused by dirty air is more common in low-and-middle in come countries, especially those in Africa, South-East Asia, and Western Pacific regions. Poor countries in these areas have the highest levels of exposure to household air pollution due to the use of polluting fuels and technologies for basic needs like cooking, heating and lighting.

Advised solutions include cleaner transport , cleaner cooking and heating fuels and technologies   energy-efficient housing and urban planning, safer industrial technologies and better waste management.

3 . Blue Planet II's latest episode(一集) focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench，have plastic in their stomachs. Indeed, the oceans are drowning in plastic．

Though it seems now that the world couldn't possibly function without plastics， plastics used by consumers are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science．

We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species，including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent．

And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers （否认者）, at least so far. To do something about it, we don't have to remake our planet energy system．

This is not a problem where we don't know what the solution is. We know how to pick up garbage．Anyone can do it．We know how to dispose （处理） of it. We know how to recycle. We can all start by thinking twice before we use plastic products. Things may seem ordinary, like using a reusable bottle or a reusable bag. But when taken collectively, these choices really do make a difference．

1. Why is plastics pollution research still a very early science?

A．The plastics pollution research is too difficult．

B．Plastics have produced less pollution than coal．

C．The world couldn't possibly function without plastics．

D．Plastics have gained in popularity too fast for science to catch up．

2. How did the author support his opinion in Paragraph 3?

A．By statistics．

B．By quotations from leading experts．

4 . Scientists in Mexico say they may have found a way to cut the production of methane, a gas linked to rising temperatures on the Earth’s surface. The scientists say their method may help reduce the methane released by cows, one of the main producers of the gas.

When talking about global warming, many people think of carbon dioxide, another heat-trapping gas. Methane is an even more powerful heat-trapping gas. Cows are known to produce high levels of methane when they eat and process food.

Researchers at the Autonomous University of the State of Mexico are studying how a cow’s diet affects the production of methane. The researchers are using a specially designed machine to measure the effect. The scientists use the machine to try to capture the animal’s breathing to examine the methane released.

Most of the gas is released when cows belch. The digestive bacteria in a cow’s stomach causes the animal to send out the gas through its mouth. There are an estimated 1.3 to 1.5 billion cows in the world. Each animal releases as much as 120 kilograms of methane per year. The U.S. Environmental Protection Agency reports that, whenever measured in pounds, the effect of methane on climate change is more than 25 times greater than carbon dioxide over a 100-year period.

As it is difficult to capture the gas released by cows for use as energy, one way to lessen its release is to change their diet. Scientists in some countries are looking for ways to decrease cow methane. But while they are trying different plants and chemical compounds, those products would be too costly and difficult to bring to Mexico.

1. How harmful is the gas sent off by cows?

A．It is more difficult to control its amount.

B．It takes up most of human-caused methane.

C．It is the key factor to prevent globe warming.

D．It is more harmful than carbon dioxide.

2. How is the harmful gas produced by cows?

A．When they digest food in their stomachs.

B．When their gas meets with air.

C．When their gas is being sent out.

D．When they breathe in air through mouths.

3. What can scientists in some countries do to settle the problem caused by cows?

A．Limit the number of cows.

B．Change what they eat.

C．Fix machines on their mouths.

D．Use their gases as energy.

4. What may be the best title for the text?

A．We Had a Better Method of Raising Cows

B．Cows Are Much More Harmful than Cars

C．Researchers Found a Way to Reduce Methane from cows

D．Two Gases Are Causing the Warming of the Planet

6 . The hemlock(铁杉) trees along the Wappinger Creek, New York, look healthy. However, scientist Gary Lovett says the white balls which provide protection for the bugs are created by a tiny insect. It’s hard to believe the tiny bug could kill a tree. However, trees can end up with millions and millions of the pests. When there are that many, it ends up killing the tree.

The bug from East Asia is slowly killing trees across the USA. The trouble-making bug is just one of many invasive(入侵的) pests that have slipped into the United States. They can hurt other living things in their new home.

Many invasive pests arrive on wooden pallets(运货板) piled inside shipping containers. They support and separate goods, and keep them from sliding around. Invasive pests often tunnel into the pallets.   How can we stop pests from riding on pallets? Lovett says new rules are needed. The companies that make pallets don’t want more rules. Congress has added an amendment(修正案) in the 2018 Farm Bill to try and prevent this problem. However, Lovett is not hopeful it will make much of a difference. Pallets are checked by inspectors. Many are sprayed with bug-killing pesticide. “I believe in the system，” said Brent McClendon, president of The National Wooden Pallet and Container Association. He also said shipping containers are checked very carefully.

Still, each year 13 million containers are shipped to the U. S. Each is full of wooden pallets. Lovett says: “Inspectors can’t possibly check everything. All it takes are a few bad pallets; we should get rid of wooden pallets.” He believes pallets should be made of plastic or eco-composite wood. Eco-composite wood is a mix of wood fiber and plastic. Insects cannot hide into it. One problem is that these choices cost more. They may be worth the extra money, though. Invasive pests cost the U.S. $5 billion a year. Trees don’t just die in forests. They also die in cities and our yards. Then, they need to be replaced. That costs money, too.

1. All the statements are TRUE except that ________.

4. What does the passage mainly talk about?

A．Invasive pests are harming plants in the USA.

B．Effective measures have stopped the pest invasion.

C．Congress contributes a lot to dealing with invasive pests.

D．Ecosystem in the USA is poorly damaged by invasive woods.

7 . It's important to learn how we can protect the environment. Here are 5R rules for us.

Reduce. If you want to reduce waste, you should use things more wisely.    1     If everyone uses paper carelessly, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the amount of waste we produce.

Reuse. You should always think of reusing things before throwing them out. For example,    2    . In a family, you may pass on such clothes to younger brothers or sisters.

Recycle. Bottles, cans and paper can easily be recycled. By doing so we can save lots of time and money. For example,    3    . The metal can be used to make new coke cans.

Recover.    4    . You have two choices: one is to throw the apples away, the second is to throw the rotten ones and keep the good ones. In this way, you are recovering the eatable parts of food.

Repair. If one of the legs of your table is broken, you should repair it. If you want to buy something newer and better, it is better for you to sell the old table, or     5    

Learn the rules to protect our environment. Let's try our best to make the earth cleaner and more beautiful.

A．give the clothes you do not use or the ones which are too small to the poor.

B．coke cans are sent to a factory, where they are smashed flat and melted.

C．A large number of trees are being cut down to make paper.

D．Trees are planted every year.

E．give it to people who can use it after repairing it.

F．don’t throw it away if you can use it.

G．When you buy a box of apples, there may be a few rotten ones.

8 . The Great Wall, China

Stretching over 21,000 kilometers, the Great Wall was built to prevent invasions and has a history of more than 2,000 years. UNESCO in February 2019 calls it an absolute masterpiece, not only because of the ambitious character of the undertaking but also the perfection of its construction.”

But perfection isn’t protection. 51.2 percent of the Great Wall had either already disappeared or is at a significant risk of disappearing. Besides for wind and rain erosion, the main reasons for the destruction of the Great Wall are human factors such as tourism, construction, human contact and so on.

Pamukkale，Turkey

Pamukkale, which means “cotton castle” in Turkish, is famous for its shining white calcite terraces (方解石阶地)with warm and mineral-rich waters overrun.

Before being listed as a World Heritage Site in 1988, Pamukkale had been severely damaged by human activities. People used hot spring water to fill swimming pools, some visitors stood on the rocks and some even bathed in the hot springs with soap and shampoo. To protect the terraces, the Turkish government has decided to pull down the hotels and require all tourists to visit this site barefoot.

Great Barrier Reef, Australia

Home to 400 types of coral and 1,500 species of fish, the Great Barrier Reef draws visitors to Australia from all over the world.

However, the Great Barrier Reef is expected to suffer from increasingly frequent bleaching events, cases in which corals turn white and may die, according to a UNESCO report. The heat waves caused by global warming have killed half of the coral here in the two years, according to a CNN report. Pollution from industry developments and harmful fishing practices are also big concerns.

The Dead Sea, Jordan

At 423 meters below sea level, the Dead Sea is 10 times saltier than the ocean, meaning that the water is so dense, even tourists who can9t swim will be able to float.

But the seaside resorts built in the 1980s now sit kilometers away from the water’s edge, which has lost half of its surface area in the past 40 years. The damage is irreversible due to the nature of the mineral industry and the type of agricultural use that has drained the water.

9 . Schools consume a large amount of energy, which has a bad effect on the environment.    1    , there are lots of ways that you can help your school save energy. Look for simple changes your school can make and band together with others to make an even bigger effect.

    2    Even something as simple as turning offthe lights when you leave a room can help to save energy. Turn off the lights in classrooms that are not being used and in other areas,such as empty bathrooms and unoccupied multi-purpose rooms.

Use natural light when the sun is bright. It may not always be necessary for you to have the lights on in your classroom. There may be times of day when the sun is especially bright andenough for what you are doing in your classroom.     3    .

Set up a recycling station at your schooL Recycling is a great way to save energy because it reduces the need to produce new materials.    4    , then ask your school principal if you can set one up.

Get others involved.    5    . Either as an individual or as a team, you can create and put up signs around your school. Try using signs that remind people of things they can do to save energy and also some signs that raise awareness of saving energy.

A．Postsigns about conserving energy.

B．Whether you are a teacher or a student.

C．Ifyour school does not have one.

D．Turn offyour computer when it's not used.

E．Shut down the lights when rooms are not in use.

F．Other times of day you might only need half ofthe lights.

G．If your school's garbage company offers recycling services

10 . According to the International Ecotourism Society, eco-travel is “responsible travel to natural areas that protects the environment, maintains the well-beings and involves education”. Eco-travel is on the rise, as more and more people become conscious about their carbon footprint.

Expert from Boundless Journeys, Matt Holmes, who works-on travel experiences towards conserving areas said, “As scientists and non-scientists learn more about how we human beings are impacting the planet, I think. more people want to do what they can while still exploring the world. Our guests are definitely interested in that aspect of our journeys. Travelers can farm their own food in Italy, managing their use of water and using solar or wind power. They can also visit n family-run camp that cares for retired logging elephants in Myanmar, know a park entry fee goes to a conservation organization in Costa Rica, employ and train members of the local community or partner with a protection group. There are lots of options for seeking out greener holiday.”

Most people believe that eco-travel is expensive and it is true. Matt explained “Anti-poaching patrols (巡逻) need to be paid, solar energy equipment costs a lot to install, building with environmentally friendly, materials is more expensive and so on. The extra cost is necessary, as you re paying to minimize your footprint and protect the places you visit, which is exactly what eco-travel is about. The financial success and sustainability (可持续性) of an eco- focused operation doesn’t come from thin air.” The industry is trying to make eco-travel affordable and make it accessible to the common people.
