1 . Many companies today hold meetings to discuss their new plans.As people are paying more attention to the environment problems,more companies are looking for ways to reduce their bad influence on the environment.Many of them achieve this by using web meeting.

    1     It’s an easy way of hosting and attending a meeting.Participants (与会者) don’t have to leave the office.Each of them will receive an invitation with the meeting time and date on it.When the meeting is ready to begin,they must sit before their computers.

With web meeting,all participants can attend the meeting at their own desks.    2     As a result,no fuel (燃料) is used and less time is taken up in attending a web meeting.

Materials for the meeting are e-mailed to all the participants before it begins.    3     For the company,this not only saves the use of paper but also greatly reduces the mailing cost.

As a meeting hall is not used,the only power for a web meeting is the power that is used by the computers.Besides,organisers don’t have to pay for food and accommodation (住宿) for the participants.    4    .

In a word,web meeting is a cheaper,greener,and more friendly way of hosting and attending a meeting.    5     So they can more easily find their working partners who have the same green ideas.In return,they develop good relationship with other companies and improve their business.

A．Web meeting is a technology that allows people to communicate better over the Internet.

B．All these mean that less energy is used.

C．Then participants can just read them on the screen.

D．Companies that hold web meeting are willing to work hard for a better environment.

E．They can be printed (打印) by the receivers.

F．They don’t need to drive a car to travel to and from the meeting.

G．Web meeting is quite popular now.

2 . China has made great improvements in environmental protection during the past 70 years.     1     Each species (物种) on Earth has a role to play in the ecosystem.

In recent decades, a series of wildlife-protection movements have been carried out by the central government.     2     The giant panda and the crested ibis are among these success stories.

The giant panda used to have a population of 1,114 in the 1970s. It now totals 1,864 thanks to 52 protection areas.     3     By the end of last year, seven of the nine pandas released had survived in the wild.     4     In 1981, only seven crested ibises were found in Yang County, Shaanxi Province.Since then, breeding programs have helped the population reach 2,000. China has even sent crested ibises to Japan and South Korea in recent years to help with the species’ survival.

    5     Key projects will be continually carried out to improve protection, including making the lists of wild animals and plants under state protection, and fighting against illegal wildlife trade.

A．As environmental damage has increased, signs of change have appeared around the world.

B．Another species was once thought to be extinct.

C．Scientists have worked to feed pandas and then release them into the wild.

D．People call for immediate protection of the remaining species.

E．The protection of several species in danger of extinction has made impressive progress thanks to the methods.

F．China will continue its efforts of the wildlife protection.

G．Protecting wildlife is, without doubt, an important part.

3 . 阅读短文内容，在空白处填入1个适当的单词或括号内单词的正确形式。

Earlier 2019,the International Center for Integrated Mountain Development published    1    most comprehensive analysis up to now of how climate change will affect the glaciers of the world,    2    (warn) that about 18,00 glaciers(冰川) will disappear by 2100.

This is a bad    3    (predict) for some 1.9 billion South Asians,    4     use water from the glaciers not only for drinking but also for agriculture, hydroelectric power,and tourism. But the survey also looked at an immediate question: As the glaciers     5    (rapid) melt, where will all the water—more than a quadrillion gallons of it, almost the amount    6    (contain) in Lake Huron—go?

The answer is that the Himalaya, for example, long defined by    7    (it) glaciers,is becoming a mountain range defined by lake. In fact, another study found that from 1990 to 2010, more than 900 new glaciers-fed lakes     8    (form) across Asia's high mountain ranges.Because of those remote locations scientists must rely    9    satellites to count them ,and new lakes appear to be growing so quickly that it's difficult for scientific teams to agree on the precise number. I's all happening much    10    ( fast) than we expected it to even five or ten years ago.

4 . More than one million single-use straws (吸管), most of them plastic, are used in the United States each day. They end up in waterways, harm sea animals, and break down into micro-plastics. Quantities of places have passed plastic-straw bans as a way to start handling the global plastic waste problem.

Straw materials: advantages and disadvantages

1. Metal

Made of stainless steel, aluminum, or even titanium, metal straws have become popular. They draw some criticism for having a metallic taste and conducting heat from a hot drink, but they’re strong and can be reused.

2. Paper

Paper drinking straws, which date from the late 1800s, often absorb liquid over time and can leave a taste or fibers in drinks. They’re the most popular throwaway choice in places with plastic-straw bans.

3. Glass

Though glass straws may be more breakable and thus less portable than reusable straws of other materials, they hold up well to washing and reuse. Some straws are made to look artistic, with colors and blown-glass designs.

4. Bamboo

This natural material can be sustainably produced and is a plant-based replacement of plastic straws. Bamboo straws are easily disposed of and turned into fertilizer. They are reusable but can be hard to clean completely and may absorb flavors.

1. What is the major problem with plastic straws?

A．Function.	B．Flavor.
C．Weight.	D．Pollution.

2. Which of the following belongs to single-use straws?

A．Metal straw.	B．Paper straw.
C．Glass straw.	D．Bamboo straw.

3. What is the advantage of the bamboo straw?

A．It can become fertilizer.	B．It is easy to clean.
C．It is portable and bendable.	D．It has different designs.

5 . 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.

6 . Record fires sweeping across the Amazon this month have been catching global headlines as scientists and environmental groups are worried that they will worsen climate change and threaten biodiversity(生物多样性).

As the largest rainforest in the world, the Amazon is   often called “the lungs of   the world”. It is also home to about 3 million species of plants and animals, and 1 million local people. The vast lands of rainforest play an important role in the world’s ecosystem because they take in heat instead of it being reflected back into the atmosphere. They also store carbon dioxide (二氧化碳)and produce oxygen, making sure that less carbon is given off, mitigating the effects of climate change.

“Any forest destroyed is a threat to biodiversity and the people who use that biodiversity,” Thomas Lovejoy, an ecologist at George Mason University told National Geographic. “The shocking threat is that a lot of carbon goes into the atmosphere,” he stressed. “Facing the global climate change, we cannot afford more damage to a major source of oxygen and biodiversity. The Amazon must be protected,” U.N. Secretary General Antonio Guterres said.

Data from the National Institute for Space Research (INPE) show that the number of forest fires in Brazil quickly increased by 82 percent from January to August this year from a year ago. A total of 71,497 forest fires were recorded in the country in the first eight months of 2019, up from 39,194 in the same period in 2018, INPE said. “It’s reported that the forest areas in the Brazilian Amazon have decreased something between 20 and 30 percent compared to the last 12 months,” Carlos Nobre, a researcher at the University of Sao Paulo, told German broadcaster Deutsche Welle.

Brazil owns about 60 percent of the Amazon rainforest, whose drop could have severe results for global climate and rainfall. The size of the area ruined by fires has yet to be determined, but the emergency has transcended(超出）Brazil’s borders, reaching Peruvian, Paraguayan and Bolivian areas.

1. What is the second paragraph mainly talking about?

A．The effects of climate change.

B．The role of the Amazon rainforest.

C．The results of the Amazon rainforest fires.

D．The causes of the decreasing biodiversity.

2. Which of the following best explains “mitigating” underlined in Paragraph2?

A．Easing.	B．Causing.
C．Worsening.	D．Benefiting

3. What can we learn from Thomas’s and Antonio’s words?

A．The biodiversity makes the rainforests unique.

B．The rainforest fires result in serious consequences.

C．The global climate crisis brings more rainforest fires.

D．The dry weather leads to the rainforest fires.

4. Which section of a magazine is this text probably taken from?

A．Sports and music.	B．Science and technology.
C．Nature and geography.	D．Business and culture.

7 . Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.

Where is the Beef

Most people like to eat meat. As they grow richer they eat more of it. For individuals, that is good. Meat is nutritious. In particular, it packs much more protein per kilogram than plants do. However, animals have to eat plants to put on weight - so much so that feeding them accounts for about a third of harvested grain. Farm animals consume 8 per cent of the world’s water supply, and they produce around 15 per cent of unnatural greenhouse-gas emissions. More farm animals then, could mean more environmental trouble.

    1     That as created a business opportunity. Though unwilling to adopt a vegetarian approach to diet, these people are keen on food that looks and tastes as if it came from farm animals, but didn’t.

The simplest way to satisfy this demand is to concentrate on substitutes for familiar products. “Meat” made directly from plants, rather than indirectly, via an animal’s metabolism, is already on sale for the table and barbecue. Impossible Foods, a Californian firm, has deconstructed hamburgers, to work out what gives them their texture (质感) and flavour, and then either found or grown botanical equivalents to these.     2    

For those who really want to eat steak while saving the planet, a second approach maybe more promising. That is “clean” meat made by taking animal cells and growing them in a factory to form strips of muscle. Steak is not yet on the menu, but burgers and meatballs may soon be. The field leader is Mosa Meat, a Dutch firm staffed by scientists.     3    By 2020, it hopes, the price of making them will have come down to about $US 11 each.

There is one more novel source of meaty protein that does not involve farm animals -at least, farm animals of the conventional sort. This is insects. Locusts (蝗虫), for example, are about 70 per cent protein. Insects do have to be fed, but being cold-blooded, they convert more food into body mass than warm-blooded mammals do and, being boneless, more of that body-mass is edible.     4     About 2 billion people eat insects already, but it seems few of us are willing to try. Changing that could be a hard sell. Grind (碾碎) the bugs up and use them as ingredients, though, and your customers might find them more acceptable. Hargol FoodTech, an Israeli startup, plans to do just that. Locustburgers, anybody?

A．The first burger it made, in 2013, cost around $300,000.

B．It launched its plant-based burger in a number of restaurants in America last year.

C．Per edible gram, insects need only a twelfth of the food that cattle require.

D．The problem is marketing.

E．Plant-based "meat" products have made it onto menus and supermarket shelves.

F．Some consumers, particularly in the rich West, get this.

8 . The world's oceans make life possible on this planet.They help regulate the global climate, absorb carbon dioxide and provide food and livelihood for billions of people.

But even though they cover more than 70% of the Earth's surface, our oceans are being ruined by lots of plastics, overfishing and increasing temperatures brought about by climate change and if there is one message this year's World,'s Oceans Summit tries to send it's that something must be done now to protect them.

The news that we have had from our scientists is that we are marching into a very hazardous situation.It's pretty obvious what is required is not just short-term change sometimes soon -these advocates are calling for complete change now.

But we have still got time over the next 10 years to lower our greenhouse gas emission(排放) to a level at which we will not reach that 2 degree warming stage.As you would know, once we get to 2 degrees, we lose all coral reefs in the world,for example.We're now training towards 3 degrees.

The biggest declaration to come out of the summit is the Blue Prosperity Coalition, which has the ambitious goal to ban 30% of the world,s ocean fishing by 2030.We've over-fished the oceans, and we have five to ten years to really reverse the trends as before or it's going to be too late.

We rely on the oceans for so many things, livelihoods, the food we eat and the air we breathe The oceans absorb a ton of carbon and if we don't fix the oceans now, it's going to be too late.

The coalition needs a lot more support from world governments and coalition members say with smart management they can achieve their goals while keeping fishing production without causing much economic hardship.

1. Which of the following best explains"hazardous"underlined in Paragraph 3?

A．dangerous.	B．Brilliant.
C．Hopeless.	D．Promising.

2. What does the text suggest people do?

A．Make a plan later.	B．Stop using plastics.
C．Ban fishing completely.	D．Reduce the greenhouse gas emission.

3. What can we learn from the text?

A．It's too late to protect the oceans now.

B．We will not reach 3 degree warming stage.

C．Great economic hardship will be unavoidable.

D．A joint effort is needed by the world governments.

4. What's the author's purpose in writing the text?

A．To emphasize the importance of the oceans.

B．To call for complete change to protect the oceans.

C．To show the alarming pollution of the oceans.

D．To talk about the bad effects of climate change.

9 . Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.

The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. “We never thought that this could be something that could kill,” recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.

Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.

It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.

What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It’s also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.

As for dealing with the root cause of the problem, the UN’s International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.

“The ocean is not our world,” comments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.

1. What does the underlined word “desensitised” in Paragraph 2 mean?

A．Stubborn.

B．Flexible.

C．Dull.

D．Friendly.

2. What’s one way to solve the problem according to the text?

A．To lower the speed of ships.

B．To reduce the number of ships.

C．To set up preserves under the sea.

D．To give the injured animals timely treatment.

3. What is the author’s attitude towards what Michel Andre has done?

A．Doubtful.

B．Disapproving.

C．Positive.

D．Uncaring.

4. What is the text mainly about?

A．A great expert.	B．Noise in the sea.
C．Animals in the sea.	D．Sea exploration technology.

10 . The climate we live in influences many areas of our lives. The quality of the food we eat，the water we drink，and our homes are all dependent upon our climate and weather. Some scientists have suggested that a warmer world would be a sicker world.

Climate researchers predict that the world climate will become warmer，with high temperatures in summer becoming more frequent and very cold winters more rare.

With winters becoming milder，there are likely to be up to 20,000 fewer cold-related deaths. However，there is a danger that bacteria would no longer die off seasonally during the cold period，which means that diseases may spread more widely.

More heat waves may increase the number of hot-weather related deaths by up to 2,800. Exposure to higher levels of UV light（ultraviolet light）could cause an extra 5，000 deaths a year from skin cancer and may cause an increase of up to 2,000 cases of eye diseases. Warmer summers may cause up to 10,000 extra cases of food poisoning each year.

Higher average global temperatures mean that diseases，or their carriers，may be able to move to areas that were previously too cold for them to survive. It is possible that a mild type of malaria（疟疾）will become established in some parts of the world and be a recurring threat for up to four months each year.

Globally，there are likely to be more floods，more droughts，and more storms，which will cause damage to our homes，food，and water supplies and then influence our health. The same could be said of an increase in flooding which would promote the spread of waterborne diseases，and droughts which would favor white flies and locusts.

Scientists have been studying the relationship between the outbreak of a severe disease in Africa and weather patterns. They believe that a rare climate pattern may come before outbreaks of the disease.

Climate change is likely to have unequal influences on the world population. Those living in poor and developing countries are going to be less able to adapt to the changes. Health influences are not likely to be limited to the human population -wildlife would also be severely affected.
