1 . The newly-elected president of Brazil, Jair Bolsonaro says that his country should withdraw (退出) from the 2015 Paris Agreement, and that Brazil’s rainforest protections are standing in the way of economic success. During the election campaign, he promised to ease protections for areas of the Brazilian Amazon set aside for native people and wildlife. Are Brazil’s rainforests in danger?

The Amazon, the world’s largest rainforest, is called “the lungs of the planet.” Each tree takes in and stores carbon dioxide from the air around it. Billions of trees pull up water through their roots and release water vapor into the air, forming tiny drops of water. The Amazon creates 30 to 50 percent of its own rainfall. Carlos Nobre, a climate scientist, says that it is almost impossible to say Just how important the rainforest is to the planet’s living systems.

Some of Bolsonaro’s support comes from business and farming groups. One supporter, Luiz Carlos, noted that farmers “are not invaders, they are producers.” He blamed the past government for supporting rainforest protections at the cost of farmers. “Brazil,” he said, “will be the biggest farming nation on Earth during Bolsonaro’s years.”

Paulo Artaxo, a professor of environmental physics at the University of Sao Paulo, says that if Bolsonaro keeps his campaign promises, then “deforestation of the Amazon will probably increase quickly — and the effects will be felt everywhere on the planet.”

Other scientists warn that if the Amazon and other tropical rainforests lose too many trees, this could affect rainfall in other areas. Without enough trees to support the rainfall, the longer and bigger dry season could turn more than half of the rainforest into a tropical grassland.

3 . In the past hundred years, a million people have died in earthquakes, another million have been killed by hurricanes and tornadoes, and 9 million have lost their lives in floods. In addition to this, many millions have died as a result of hunger and disease. We should also not forget in many of the world's countries, drought—serious water shortage—is a fact of life, especially in the African Sahel area bordering the Sahara Desert.

Scientists and engineers around the world have made great advances in earthquake engineering. It is, of course, physically impossible to move cities such as Tokyo and San Francisco that have been built on earthquake belts. But most often it is not the earthquake that kills people. It is the falling buildings, bridges and so on that cause deaths, and such a happening can be greatly reduced by better building programs.

Finally, perhaps we need to consider the natural disasters that we are causing ourselves. Through our mismanagement of the planet's resources we have sped up the dying out of hundreds of sorts of plants and animals, at the same time possibly destroying our own long-term surroundings for life. Maybe this is one disaster that could be prevented if we are willing to act with a sense of responsibility.

5 . A new phone app uses shaking from smartphones to warn people about earthquakes. The new app is called MyShake, which is the work of four researchers at the University of California, Berkeley.

Smartphones are equipped with accelerometers （加速器）.MyShake uses phone accelerometers to measure seismic （地震的）activity. It has been programmed to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time. A smartphone sends seismic information to the app developers. If the developers receive several warnings from one area it recognizes that an earthquake may be taking place or will take place soon. Using information sent from the app, the network then judges the location and strength of the quake in real time. MyShake can record 5. 0 earthquakes at distances of 10 kilometers or less.

MyShake uses very little power according to its developers. Only when seismic activity is sensed by the app does it become active and sends data to the network. The app works best when your phone is resting on a flat surface like a table.

The developers hope that MyShake can add to information collected by the US Geological Survey. That US agency has created the Earthquake Early Warning System also known as the EEW. The EEW has used sensors for measuring quakes in many areas. In places where no such equipment exists MyShake may be the only method of early quake detection（发现）. The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.

The developers say they hope to add a feature that will warn people about a possible tsunami（海啸）after an earthquake.

1. What's the main idea of the first two paragraphs?

A．What seismic activity is,

B．What MyShake is and how it works.

C．When accelerometers record earthquakes.

D．MyShake plays an important role in reporting earthquakes.

2. What can we learn from the passage?

A．Only when smart phones are placed on a flat surface can it work.

B．The smart phone can warn its owner when it senses an earthquake.

C．MyShake can quickly send seismic information to the app's developers.

D．MyShake can sense the difference between normal activities and earthquakes every time.

3. What probably will the app developers hope to do next?

A．To better the EEW.

B．To combine the EEW and MyShake.

C．To add its function to warn the possible damage after an earthquake.

D．To use the information by the U.S. Geological Survey to better MyShake.

4. Which of the following could be the best title of the passage?

A．MyShake will Be Used in Earthquakes

B．MyShake Is on the Way to Predict Earthquakes

C．MyShake Has Been Developed to Predict Earthquakes

6 . On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedo !

Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine life. When asked why he doesn't wear a wetsuit(防寒泳衣), Pugh says, "I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I'm asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message."

It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1.6 degrees Celsius. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.

Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.

This is not the first time that Pugh has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica's Ross Sea as part of his successful campaign to help set up a marine reserve there.

1. Why did Lewis Pugh swim without a wetsuits ?

A．To show his bravery.

B．To swim faster.

C．To build up his body.

D．To have overnight fame.

2. What does the underlined word "it" in Paragraph 3 refer to'?

A．His body temperature.

B．His body

C．The water.

D．The water temperature.

3. What's Pugh's advice about swimming in freezing waters?

A．One should be expert at swimming.

B．One must be used to long-distance swimming.

C．One should be ready to take on challenges.

D．One must be adequately prepared for it.

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

A．Lewis Pugh: achieving the impossible

B．How to survive a swim in cold waters

C．Lewis Pugh: swimming for a cause

D．How to prepare for extreme swimming

7 . Some of the greatest problems we face today are the destruction (破坏)of our environment.Brown clouds, polluted water, endangered wild animals..., these problems seem so huge.

So my family does what we can. We take cloth bags to stores instead of using plastic bags. We walk where we don’t have to drive.

But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world?

I recently learned something about flamingos(火烈鸟)which like to get together in groups of a thousand or more Every year when the time comes for migration (迁徙), a few of them first take off from the lake. But none of the others seem to notice, so the small group returns. However, the next day they try again. This time a few more fly along with them, but most of them still pay no attention, so they return again. They try for several times. Every time a few more birds join in but ,since the thousands of others still take no notice, the great migration plan is once more stopped.

Then one day something changes. The same small group of birds once again starts flying and a small number more join in just as before, then more. Finally, they all take flight and the migration really begins. What a spectacular sight it must be--thousands of flamingos taking off into the sky at once!

A few can make a difference. Even if you’re the one to take the first step, and continue trying,others will someday take notice and together we will solve even our greatest problems.

3. What does the underlined word “spectacular” in Paragraph 5 probably mean?

A．Disappointing.	B．Fantastic.
C．Terrible	D．Surprising

4. What's the writer's purpose of writing this article?

A．To show that the writer loves to see the migration of flamingos.

8 . 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.    1    

Lowering Your Energy.

Turn off lights and unplug power strips (电源插板) that you’re not using.     2     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 sleep mode instead of simply leaving it on.

Using public transportation.

    3     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.

    4    

Say no to unnecessary plastic straws, lids, 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.

Considering growing a plant.

They add more oxygen to the air, which means a less polluted air. If you don’t have a green thumb, choose some plants that are rather easy to look after.     5     If possible, grow more than one plant.

A．Reduce your gas consumption and carbon emissions by walking, biking, or taking the bus.

B．Here are some suggestions for you to live an eco-friendly life.

C．Use less energy during the hot summer months and cold winter season.

D．This is an easy way to reduce energy use.

E．Using items more than once.

F．Cutting Back on Plastics and Waste.

G．“Lucky Bamboo” is especially good for that, since it demands nearly no attention.

9 . Let's take a minute to think about the water we use. The human body is 60% water and we need to drink lots of water to be healthy. When we are thirsty we just go to the kitchen and fill a glass with clean water.

    1    For example, farmers, who produce the food we eat, use water to make the plants grow. When we turn on a light or switch on a TV or a computer we use energy and we need water to produce this energy.

The truth is that we are lucky enough to have clean water whenever we want，but this is not the case for many people around the world.    2    That's around one in 10 people in the world. If we drink dirty water，we can catch diseases from the bacteria and become ill. Every year over 500，000 children die from diarrhea(腹泻)from dirty water. That's around 1，400 children every day！Also，in some countries children walk many kilometres every day to get water.    3    Therefore，they don't have time to learn how to read or write and don't get an education.

    4    On this day every year，countries around the world hold events to educate people about the problems of dirty water and that clean water is something that everyone should have around the world. At one school in the UK，children between the ages of 10 and 15 walk 6km with six litres of water.    5    People give them money to do this and all the money helps get clean water to as many people as possible around the world.

A．We use water indirectly too.

B．Every system in our body depends on water to function.

C．It is to inspire people to learn more about water-related problems

D．If children walk many hours a day to get water，they can't go to school.

E．Did you know that around 750 million people do not have clean water to drink？

F．In 1993 the United Nations decided that March 22nd is the World Day for Water.

G．In this way，they know how it feels to walk a long distance carrying heavy bottles.
