1 . 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.

2 . Are you facing a situation that looks impossible to fix?

In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It    1    (be) unimaginable that it could ever be cleaned up. The river was so polluted that it    2    (actual) caught fire and burned. Now, years later, this river is one of    3    most outstanding（杰出的）examples of environmental cleanup.

But the river wasn’t changed in a few days    4    even a few months. It took years of work     5    (reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is    6    (clean) than ever.

Maybe you are facing an impossible situation. Maybe you have a habit    7    is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?

While there are    8    (amaze) stories of instant transformation, for most of us the    9    (change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be     10    (patience).

4 . 阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

As an attractive city in the Netherlands, Amsterdam is one of the most bicycle-friendly    1    (city) in the world having over 800, 000 bikes in the capital. By comparison, the city has a population of only 750, 000 less than the number of bikes. According to a survey    2    (make) 5 years ago 490, 000 people used bicycles everyday.

Up to now, people in Amsterdam    3    (enjoy) the convenience of cycling for decades. The city has special facilities for cyclists,    4    can be used for free. Compared with other transportation in the city, bikes are    5    (clean) and less expensive while also    6    (offer) health benefits.    7    reason for bicycle riding is that bicycle traffic is    8    (relative) safe. Amsterdammers ride a wide    9    (vary) of bicycles. Many tourists also discover Amsterdam by bike, which is    10    typical Dutch way.

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

There     1     (be) no lights in sight but the night sky glowed (发出) a dusky yellow, because the Amazon was burning. The yellow flames engulfed (吞噬) trees     2     lit up the sky. During the day, the sunshine was blocked     3     thick smoke. So far, the fire     4     (put) out.

The government has recorded 72, 843 fires. The fire is just one of     5     (they) in the Amazon, the world’s     6     (large) rainforest and a fighter against climate change. According to Brazil’s space research agency INPE, the wildfire has decreased by 17 percent so far this year compared to the same period in 2018.

Environmental     7     (group)said the policies of the government encouraged deforestation (采伐森林) of the Amazon,    8     led to more fires. But the government posted a report and wanted     9     (argue) against that. The government claimed that non-governmental organizations     10     (angry) set fire to the forest after it cut their funding.

6 . Blue Planet II's latest episode (情节) focuses on how plastic is having a destructive 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, oceans are drowning in plastic.

Though it seems that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining 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, but 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 in the same breath 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 deal with it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag-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．Plastics have gained popularity too fast for science to catch up.

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

A．The oceans become choked with plastic.	B．Ocean plastic is a global issue.
C．Blue Planet II has left viewers heartbroken.	D．Plastics gain in popularity all over the world.

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.

8 . There is a huge need for shark fins (鳍) in Asian countries. As a result, many sharks are caught and killed. According to reports, sharks are being killed at an shocking rate (速度) of up to 273 million worldwide every year.

Some experts predict that if the killing continues at the current rate, many shark species will be lost forever. It can be very dangerous. Sharks are very important and they should be protected.

In a study of the east coast of the United States, 11 species of sharks were eliminated from their range. Of the 14 species of ocean life that those sharks used to eat, the populations of 12 exploded and caused great damage to the ecosystem. For example, the cownose ray (鳐) population was no longer kept under control by sharks and so grew out of control. As a result, the rays destroyed the population of bay scallops (扇贝), their favorite food. The scallop fishery, which had been in good condition for over 100 years, was destroyed completely. Also, the removal of the scallops most likely had an effect on water quality as they were no longer there to perform their function (功能) of cleaning the water.

Sharks tend to eat very efficiently (高效地), going after the old, sick, or slower fish in a population, keeping that population healthy. Sharks help keep many populations of ocean life to the right size so that those prey (猎物) species don’ t do harm to the ecosystem by becoming too populated. The ocean ecosystem is made up of very complex (复杂地) food webs. For the most part, sharks are at the top of these webs and are considered by scientists to be “keystone” species, meaning that removing them may cause the whole structure to fall apart. Therefore, we should protect sharks because doing so is to protect the whole ecosystem.

3. After the number of cownose rays greatly increased, ________.

A．water quality improved as well	B．bay scallops grew out of control
C．there are more food for shark	D．the local scallop fishery was harmed

4. What can we know about sharks from Paragraph 4?

A．They can’t find enough food to feed on.

B．They never eat the old, sick or slower fish.

C．Their large populations can harm the ecosystem.

D．They play a key role in keeping the ecosystem healthy.

9 . 阅读下面材料，在空白处填入1个适当的单词或括号内单词的正确形式。

People are wasting things everywhere and every day. Wherever we go, we can see that paper, bottles and cans are thrown away; food     1     (waste) just because of its poor taste; clothes are thrown around simply due to their old fashion Not only things and money are wasted, but natural resources are wasted as well.     2     (tree) are cut down merely for fuel; wildlife is killed     3     (simple) for food; coal and minerals are exploited (开采) in     4     bad way.

The worst example of man’s waste is the waste of time. Many people tend to spend their time on     5     (worth) things, such as wandering about (漫步) in the street, gossiping in the office, or     6     (sleep) too much during the day. As we know, time is so valuable to us that it never returns if it     7     (pass) by.

It is time     8     (call) for an end to waste. On the one hand, we must save natural resources and make full use of them,     9     is very important to our future; otherwise human beings will be faced with the lack of natural resources and suffer     10     pollution caused by waste. On the other hand, we must value our time. Only with our time devoted to study and work for the people will we never regret the life we have had.

10 . The future of Australia’s solar industry is looking bright after a record 3.5m panels(嵌板)were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (产能) in small scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.

Australia’s solar power prosperity could almost double capacity in a year, The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solar choice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.

The regulator’s executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions,

“We are seeing a wide cross section of Australians—households, community centers, schools, and small businesses—receiving rewards under the small scale renewable energy scheme,” Williamson said, “Our data shows consumers are embracing renewable energy to take control of their electricity bills. ”

In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57 %. “I he data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength, It looks like 2018 will be another big year for the solar industry.”

The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria’s Latrobe Valley has a capacity of 2, 200MW.
