There comes a time when the old must give way to the new. Finding and     1     (keep) the right balance between progress and the protection of cultural sites can be     2     big challenge.

In the 1950s, the Egyptian government wanted to build a new dam across the Nile     3     (control) floods, produce electricity and supply water to more farmers, but the proposal led to     4     (protest).

After listening to the experts’ opinion, the government turned to the United Nations for help. Then a committee     5     (establish) to limit damage to the Egyptian buildings and prevent the loss of cultural relics.     6     (final), a document was signed, and the work     7     (begin) in 1960.

    8     the project ended in 1980, it was considered a great success. Not only had the countries found a path     9     the future that did not run over the relics of the past, but they had also learnt that it was possible for countries to work together to build a better tomorrow. The spirit of the Aswan Dam project is still alive today.   If a problem seems too difficult for a single nation, the     10     (globe) community can sometimes provide a solution.

2 . 根据课文内容，在空白处填入1个适当的单词或括号内单词的正确形式。

Here     1     (be) some common “green truths” that have been shown to be only half true, or even     2     (complete) false.

First, paper shopping bags are better than plastic ones. In fact, both kinds of bags are bad     3     the environment. Plastic bags cause litter and are a danger to wild animals,     4     mistake them for food. It takes hundreds of years for plastic     5     (break) down.

However, making a paper bag uses four     6     (time) as much energy as making a plastic bag and up to three times the amount of water.

Second, when you turn off a device, it stops using power. Electricity continues to leak from the device, even when it     7     (turn) “off”. So we should remove the plug from its power supply.

Third, eating local food is good for the environment. In fact,     8     is the production of food that uses most of the energy. In some cases, local produce might have used     9     (much) energy than produce grown a long way away — even taking into account its transport.

Fourth, it’s better to take a shower than a bath. Actually, if you spend more than eight minutes in a shower, you’ll use as much water as in a bath—about 50 litres of water.

Environmental awareness is now part of daily life. But it’s worth     10     (check) common ideas and opinions to see what’s really green.

3 . Before you throw that old cell phone in the trash, or hide it away in a drawer, think again. There are actually many ways to deal with a mobile phone that you are no longer using.

First, you should be aware that in many places, throwing away cell phones is actually illegal because the batteries, especially in very old phones, can contain poisonous metals.     1    .

    2    . In fact, most companies that recycle them get paid to do so. This had led to many charities making a small amount of money by collecting old phones. There are large organizations that will take unwanted phones. However, you might also want to think locally.

Many schools and local charities now have recycling programs. And they do make a little bit on each donation.     3    , you might consider starting a small local one, perhaps for a local public school. Check first, since so many schools have gotten the jump on recycling them already.     4    , or smaller and better phones, there are plenty of old cell phones just waiting for a place to land, and smart schools have provided that place.

You might also want to hang onto any accessories(配件)that you have.     5    . Continuing to use

A．You certainly don’t need to pay to recycle an old cell phone

B．There are better places to get rid of them than your trash can

C．Things like chargers or covers can often be used with your new phone

D．Local charities have contributed a lot in repairing unwanted phones

G．If you can’t find a large cell phone recycling program in your area

4 . 课文内容填空

With the development of society, chemical pesticides and artificial fertilisers have been in     1     use in farming for many years. They can help fight crop     2     and increase production. However, they can cause many problems     3    . For instance, pesticides can kill     4     bacteria and insects and crops grown with chemical fertilisers usually grow     5     to be full of nutrition. As a result, many people worry they may make them ill and even cause cancer.

To tackle this problem, farmers use natural waste as     6     and they often change the kind of crop grown in each field every year and they also plant diverse crops that use different     7     of soil to help keep it rich. But organic farming is nowhere near able to     8     the high demand for food. Therefore, there is still a long way to find a     9     solution that puts sufficient food on the dinner table while keeping people and the environment as     10     as possible.

5 . Tips for Green Travel with Kids

Traveling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids:

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放).     1    , check in with other local airports to see if nonstop flights are available. You might have to drive a bit further, but saving on carbon emissions makes it worthwhile.

Whether you’re flying or driving, it’s easy when traveling to pull into fast food restaurants for snacks.     2    . My kids love to help plan snacks. I let them create their own snacks for the trip at home.

Reusable water bottles are easy to bring along whenever you travel. At the airport, keep your reusable bottles empty until you have passed through the security (安检).     3    . Single-use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

    4    . Open a few windows and turn off the air conditioner. You should also help your children keep their good, green habits from home to place while traveling. Sometimes vacation can mean more than one shower each day — once in the morning and again after getting out of the pool. Pay attention to the number of showers and the length of showers.     5    .

A．Too much carbon emissions seriously pollute the environment

B．But you can pack healthy food before starting off

C．In this way, you can save water and energy

D．Fill them up on the other side of the security checkpoint

E．Security check is a necessary part of each trip

F．Save energy by turning off the hotel room lights when you head out for the day

G．If the closest local airport doesn’t have nonstop flights to a certain place

6 . There are more than 7 billion people on Earth. Imagine what will happen if each of us decides to do one thing — no matter how small — to protect wildlife every day. Even little actions can have a major influence when we all do something.     1    .

Raise an animal

From wild animals to wild places, there’s a choice for everyone.     2    . It is a small and easy action but of great importance.

Do some volunteer work

    3    , you can offer your time. Many organizations and zoos have volunteer programs. You can help clean beaches, rescue wild animals or teach visitors. Zoos, national parks and wildlife protection areas are all home to wild animals. Learn more about our planet’s species from experts. See Earth’s most amazing creatures up close.

Speak up and join

Share your concern for wildlife protection with your family. Tell your friends how they can help. Ask everyone you know to do what they can to stop wildlife trafficking (非法交易).     4    , find the organization and take part. Become a member. Actively support the organization of your choice.

    5

E．Get together with classmates to raise an animal from a wildlife organization

F．Here are ways you can make a difference

G．If you are busy with your work or studying

7 . Used electronics are piing up fast: they are filling up landfills with dangerous pieces of waste. Some e-waste is relatively large, such as air conditioners; other e-waste is more unnoticed, such as smart labels that contain disposable batteries and other equipment.

“It’s these small batteries that are big problems,” says University of California, Irvine, public health scientist Dele Ogunseitan, who is a green technology researcher and adviser for major tech companies and was not involved in developing the battery. “Nobody really pays attention to where they end up.” Researchers at the Cellulose & Wood Materials Laboratory at the Swiss Federal Laboratories for Materials Science and Technology are working to address this problem. Their new paper describes a water-activated paper battery developed from environmentally friendly materials that could eventually present a sustainable alternative to the more harmful batteries common in low-power devices.

The paper battery has the same key components as standard batteries but packages them differently. Like a typical chemical battery, it has a positively charged side and a negatively charged side. A traditional battery’s components are covered in plastic and metal; in the new battery, however, the positively and negatively charged sides are inks printed onto the front and back of a piece of paper. That paper is filled with salt, which dissolves (溶解) when the paper becomes wet. When the paper is dry, the battery is shelf-stable. Once the paper is wet, the battery starts working within 20 seconds. The new battery’s operating performance declines as the paper dries. When the scientists rewet the paper during testing, the battery regained function and lasted an hour before beginning to dry out again.

That future may not be so far off. It is hard to predict a time line for manufacturing such items at scale, but the head of the study says he is in contact with potential industry partners and believes these batteries could make their way into products within the next two to five years.

8 . In the old days, when you had to drive to a movie theater to get some entertainment, it was easy to see how your actions could have an impact on the environment. After all, you were jumping into your car, driving across towns, coughing out emissions (排放) and using gas all the way. But now that we’re used to staying at home and streaming (流式传输) movies, we might get a little proud. After all, we’re just picking up our phones and maybe turning on the TV. You’re welcome. Mother Nature.

Not so fast, says a recent report from the French-based Shit Project. According to Climate Crisis: The Unsustainable Use of Online Video, digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Watching a half-hour show would lead to 3.5 pounds of CO2 emissions. That’s like driving 6.28 kilometers. And in the European Union, the Eureca project found that data centers (where videos are stored) there used 25% more energy in 2017 compared to just three years earlier, reports the BBC.

Streaming is only expected to increase as we become more enamored of our digital devices (设备) and the possibility of enjoying entertainment where and when we want it to increase. Online video use is expected to increase by four times from 2017 to 2022 and account for 80% of all Internet traffic by 2022. By then, about 60% of the world’s population will be online.

You’re probably not going to give up your streaming services, but there’re things you can do to help lessen the impact of your online use, experts say. For example, according to Lutz Stobbe, a researcher from the Fraunhofer Institute in Berlin, we have no need to upload 25 pictures of the same thing to the cloud because it consumes energy every time. If instead you delete a few things here and there, you can save energy. Moreover, it’s also a good idea to stream over Wi-Fi, watch on the smallest screen as you can, and turn off your Wi-Fi in your home if you’re not using your devices.

9 . Children from four Buckingham shire primary schools visited Epilepsy Society to plant a hedge (树篱) as part of a Plant-for-the-Planet project. The children from these schools were planting a hedge in the garden of the Queen Elizabeth House at the charity in Chalfont St Peter. Plant-for-the-Planet gives children across the globe the opportunity to learn about the threats of global warming to the environment, and then put their new knowledge into practice as they plant new trees.

The day was organised by Bob Sherren who showed the children how to plant the planet-friendly line of trees in protective chambers (防护室) to shield them from hungry wildlife as they settle in their roots. Bob said, “The day really was ‘Thinking Globally, Acting Locally’ put into action. The children learned about the importance of planting trees as a way of helping to bring about climate justice (正义) for many living in poorer nations and of course enjoyed planting the trees too.” The eventual hedge, which will grow to full size over ten years behind the Queen Elizabeth House, is made up of trees such as oaks, silver birches and so on.

Bob added, “The children were also able to help people living at Epilepsy Society because they will gain some well-needed privacy from the hedge in time. The natural wildlife benefits too from the fruits and nuts that a hedge made from native species can provide as well as the possibility for any number of nesting sites.”

Emma Darlington, Epilepsy Society’s volunteer officer, said, “I think it’s so important to encourage the younger generation that the future is in their hands and that they can make a difference, whether it is through taking part in projects like this or spreading awareness. We hope they learn a little bit about the work we do at Epilepsy Society too — the trees they planted will be enjoyed by everyone here for years to come.”

10 . The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food, bamboo, which makes up 99% of their meals.

Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.

A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature rises 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report’s authors.

He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening all around the world.”

In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.

“But it is far from enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from the World Wildlife Fund but not a member of the team.

The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of China’s wild panda population. In addition, about 375 are living in research centers and zoos in China.

1. How many wild pandas are there in China?

A．About 260.	B．About 635.

B．It is difficult to control the temperature rise within 3.5℃.

C．Bamboo is sensitive to the changes of temperature.

D．China is making great efforts to protect the pandas.

3. What can we learn from the first paragraph?

A．The Qinling Mountains can provide enough bamboo for the pandas.

B．Pandas in the Qinling Mountains are only threatened by the loss of food.

C．Lots of the bamboo in the Qinling Mountains will probably disappear.

D．Pandas have already eaten 99% of the bamboo in the Qinling Mountains.

4. Which can be the best title for the text?

A．The Disappearance of Bamboo

B．Necessity to Change Pandas’ Food

C．A New Threat Faced by the Pandas
