Growing numbers of travelers are deciding not     1    (fly) in order to help save the planet even if it means     2    (spend) days on a train. The no-fly movement is small but many    3    have joined it think it will eventually receive       4     same attention as the no-plastic or less-meat movements because of flying’s 2%     5    (contribute) to carbon emissions, which they say could rise to 16% by 2050. Some supporters suggest that people should fly no more than once per year and any further flights should be taxed. Critics of the movement, however, argue that most flying is done by small numbers of people when     6    (compare)to other forms of transport and so flying is an easy target. Much more environmental damage is done by cars they argue. But people won’t target     7     (driver) because the majority of people drive. In addition, the no-fly movement     8     (lead) by people who don’t really need to travel very far and have plenty     9     free time to spare. Most people who fly, they say,     10    (rare) have time to spend extra days getting to destinations and employers are unlikely to give employees extra time off so they can be kind to the environment.

4 . We all know that forests-especially rainforests-absorb carbon dioxide and produce the oxygen that all living things depend on. It’s no wonder that they have been named the lungs of the planet. Today, after the big fires in the Amazon, Alaska, Greenland, and even Siberia, it’s very clear that we need to grow a forest that is fireproof. That’s not an impossible dream. We can grow seaweed forests that are fireproof because they are underwater.

Seaweed can store carbon and help reduce the influence of global warming. Now, seaweed is being farmed in small ocean farms to be used for food, medicines, and beauty products. If seaweed can be grown on a large scale(大规模地), it could help to fight against global warming.

“Seaweed is finally having its moment in the spotlight,” said Halley Froehlich, a scientist at the University of California. She is the lead author of a new study published in Current Biology. The study shows that large-scale seaweed farming could be used to cancel out land-based carbon emissions and it mapped the areas of the oceans where seaweed could be grown.

Now, only 3.8 percent of the US waters off the coast of California are being used to grow seaweed but that is just 0.065 of the ocean that can be farmed. In fact, 48 square kilometers of the world’s oceans can be used for seaweed farming.

For seaweed farms to be part of the global solution, they will have to be much larger. To create underwater forests, seaweed would have to be grown, harvested and then sunk into the deep ocean so that the trapped carbon could be buried for years to come.

While it sounds like a good plan on paper, “The technology doesn’t yet exist” to keep seaweed in the deep ocean, said Froehlich. “Hopefully this paper encourages conversation among engineers and economists about what it would take for the actual tools to be put in place.”

5 . Yosemite is a national park in California. It is very beautiful and big. The park includes more than 760,000 acres in the California Mountains. Most of the park is wilderness.

The part of Yosemite that everyone likes is Yosemite Valley. It is a tiny valley that is 7 miles long and less than 1 mile wide. It has tall rock walls and streams that splash down in waterfalls. More than two million visitors come to the valley each year.

One ranger (守护人) says the number of visitors is more than the land can handle. The valley has 4,500 camping spots. It has a hotel that can hold 4, 000 families. This is still not enough to handle all of the visitors. The valley has grown so big that it has a lot of traffic and crime.

A worker says the park is trying to keep the beauty of the park and let everyone visit. Some areas have been fenced off from people and planted with seeds to try to keep them beautiful.

A former worker thinks Yosemite should get more money to take better care of the park. He would also like to teach people what the park service is trying to do.

Some people are trying to save Yosemite Valley. A plan has been made to get rid of some buildings. There will be fewer cars allowed inside the park. More buses will help get people around.

A．Some of the trees.	B．Some of the water.

We already know the fastest,least expensive way to slow down climate change:use less energy.With a little effort,and not much money,most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.
Not long ago,my wife,PJ,and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change.Scientists have reported recently that the world is heating up even faster than predicted only a few years ago,and that the consequences(后果)could be severe if we don’t keep reducing emission(排放)of carbon dioxide(CO₂)and other greenhouse gases that are trapping heat in our atmosphere.
We decided to try an experiment.For one month we recorded our personal emission of CO₂.We wanted to see how much we could cut back,so we went on a strict diet.The average US household produces about 150 pounds of CO₂ a day by doing common things like turning on air conditioning or driving cars.That’s more than twice the European average and almost five times the global average,mostly because Americans drive more and have bigger houses.But how much should we try to reduce?
For an answer,I checked with Tim Flannery,author of The Weather Makers:How Man Is Changing the Climate and What It Means for Life on Earth.In his book,he had challenged readers to make deep cuts in personal emission to keep the world from reaching extremely important tipping points,such as the melting(融化) of the ice sheets in Greenland or West Antarctica.“To stay below that point,we need to reduce CO₂ emission by 80 percent,”he said.
Good advice,I thought.I’d opened our bedroom windows to let in the wind.We’d gotten so used to keeping our air-conditioning going around the clock.I’d almost forgotten the windows even opened.We should not let this happen again.It’s time for us to change our habits if necessary.
1. Why did the author and his wife try a new diet?

A．To take special kinds of food.

B．To respond to climate change.

C．To lose weight.

D．To improve their health.

2. The underlined words“tipping points”most probably refer to “ ”.

A．freezing points	B．burning points
C．melting points	D．boiling points

3. According to the passage,Tim Flannery .

A．made deep cuts in his personal emission of CO2

B．wrote a book about the climate changes

C．succeeded in reducing CO2 emission by 80 percent

D．was an author popular among readers

4. Which of the following would be the best title for this passage?

A．Saving Energy Starts at Home

B．Changing Our Habits Begins at Work

C．Changing Climate Sounds Reasonable

D．Reducing Emission of CO2 Proves Difficult

7 . A green roof is a roof of a building that is covered with vegetation over a waterproof membrane (防水膜). It is a proper method of growing plants on the roof and does not refer to the mere green color of the roof. People benefit a lot from these green roofing systems, and they are gaining popularity day by day.
Human beings have occupied major areas of land and transformed them into huge buildings, which has severely affected the environment and the natural habitat of bird and insects. Green roofing compensates for that. It creates a natural habitat for creatures like bees, grasshoppers and other insects.
Modern roofs need a lot of energy to control the temperatures in winter and summer. However, green roofs reduce the amount of energy required for controlling temperatures, thus making them energy-efficient. As green roofing is highly energy-efficient, it can act as a encouragement for people who are interested in green roofing systems and their benefits. It will increase the market value of the building and fetch the owner a great share of profit.
As the vegetation requires a water supply, there is a inbuilt water preservation layer in the green roof system. This layer helps to keep the rainwater. It makes full use of the rainwater and prevents wastage. During heavy rains, the water runs off the flat roof. The green roof prevents this overflow by slowing down the volume of running water.
Green roofs can compensate for the lost greenery in urban areas and increase the artistic value of an area. Your building will look beautiful, coated with green vegetation. Green roofs can serve as local community garden and create a natural atmosphere, giving physical and psychological benefits like reducing stress levels in people and keeping them physically fit. Besides, people can start their own small-scale cultivation (栽培) and experience the pleasure
of gardening.
