1 . Earth Hour is organized by the World Wide Fund for Nature. It's a big event usually at the end of March every year. On this evening, people “go dark”.     1    

It's true that turning off lights for just one hour saves only a small amount of power.    2    On one level, joining in Earth Hour makes people think about the problem of climate change and what we can do in everyday life to protect nature.

But on another level, a large number of people’s acting together sends a powerful message to governments and companies.     3     They begin considering green issues when big decisions.

The logo(标识) of Earth Hour is “60+” .The number 60 is for the 60 minutes of Earth Hour.     4     In fact, people who join in Earth Hour say that taking part makes them want to do more for the environment.

    5     Musicians give concerts by playing acoustic(原声的) instruments instead of electric ones, and using candles instead of electric lights. Celebrity chefs have created special recipes for families to prepare and eat by candlelight. Tree-planting sessions, group walks and runs are also among the options.

A．But this is only the beginning.

B．Earth Hour represents every hour of every day.

C．After all, everyone has to answer for what they have done.

D．Besides turning off the lights, people get involved in other events.

E．It pushes them to take urgent measures by making changes to policies.

F．That is, they switch off all unnecessary lights at the same time for one hour.

G．The plus invites people to continue their action even after Earth Hour is finished.

2 . Several companies have begun creating paper bottles to replace glass and plastic ones. Paper bottles are easy to recycle, and also weigh less than glass or plastic, meaning they'll require less energy to produce and move around.

A company called Paboco has been working with other companies to develop paper bottles. The companies are creating their own bottle designs, but they're sharing what they learn to promote the development of paper bottle technology

One of the biggest challenges is preventing a paper bottle leaking（泄漏）. The inside of the bottle needs a special coating to make sure the liquid doesn't leak through. Many companies are lining（做衬垫）their bottles with a thin sheet of plastic. Though bottle makers may say this liner can be recycled, many recycling programs don't have the right machines to handle these liners.

A Danish beer company called Carlsberg is working with Paboco on a paper bottle called the "Green Fiber Bottle". Currently the bottle uses a plastic liner. In the future the company hopes to use a "bio-plastic" that will break down naturally over time, And a company named Diageo just announced the first paper bottle whose inside uses a non-plastic coating.

But even without the plastic, paper bottles aren't perfect. Most paper bottles use wood pulp（纸浆）, meaning trees need to be cut down. To solve this problem, Frugalpac, a company from the United Kingdom, has created wine bottles made of recycled paper. Frugalpac still uses a plastic liner, though.

Companies will need to see how long liquids can be stored in the paper bottles and make sure the bottles don't affect the taste. But with so many companies working toward the same goal, it's likely that we can expect to see paper bottles on store shelves in the near future.

1. What is the advantage of paper bottles over other ones?

A．They cost less.	B．They are more appealing.
C．They are easier to produce.	D．They are more eco-friendly.

2. What is the most difficult task to creat paper bottles?

A．Finding recycling liners.

B．Getting the right machine.

C．Preventing the liquid escape.

D．Making sure of the storage time.

3. What does the author think may solve the problem of unperfect paper bottles?

A．Cutting down fewer trees.	B．Using recycled paper.
C．Producing "bio-plastic" liners.	D．Still using plastic liners.

4. What does the author feel about the future of paper bottles?

A．Hopeful.	B．Doubtful.
C．Satisfied.	D．Worried.

3 . Crows are not the most beautiful bird. They don't have a good fame in most countries of the world.     1     They are definitely one of the smartest, most adaptable of our winged friends.

    2     However, some of these species may also have small areas of white or gray feather around their body. And they are compact（结实的）birds with functional beaks and feet.

Crows are very socialized to groups These groups of crows are referral to as "flocks" or "murder". The American crow, also known as the common crow, is of the Corvidae family. This includes 120 species.     3    

In a variety of studies crows have been proven to be extremely intelligent. These studies confirm that the birds are able to construct and use tools in their life.     4     Crows have actually evolved into making hooked tools from twigs to help them forage. They are also able to drop pebbles into a lube of water to allow them to drink the water.

    5     And they also stash and store food in trees and other places for future use. They are highly adaptive birds that eat over six hundred different kinds of stuff. They eat almost all types of plants. And they also feed on insects like spiders, grasshoppers, weevils, beetles and crickets. As scavengers（食腐动物）they feed on decaying and dead matter. And also eat waste and food from garbage biw, especially in the winter months.

A．These birds consume many varieties of food.

B．Ravens and jackdaws are included in that number.

C．They usually don't spend too much time in their nets.

D．Common crows are generally all-black in appearance.

E．For example, they use sticks to dig bugs from trees to eat.

F．These birds get on well with each other when they hunt for food.

G．But they are believed to be one of the most intelligent birds on the earth.

4 . 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。

When a tornado(龙卷风) touched down in a small town nearby,many families were left completed ruined. Afterward all the local newspapers carried many human-interest stories featuring some of the families who suffered the hardest.

One Sunday, a particular picture especially touched me. A young woman stood in front of an entirely shattered(破碎的) mobile home, a depressed expression on her face. A young boy, seven or eight years old, stood at her side, eyes downward. Clutching(紧握) at her skirt was a tiny girl who stared into the camera, eyes wide with confusion and fear.

The article that went with the picture gave the clothing sizes of each family member. With growing interest, I noticed that their sizes closely matched ours. This would be a good opportunity to teach my children to help those less fortunate than themselves. I stuck the picture of the young family on our refrigerator, explaining their difficulty to my seven-year-old twins, Brad and Brett, and to three-year-old Meghan.

“These poor people now have nothing,” I said. “We’ll share what we have with them. I brought three large boxes down from the room upstairs and placed them on the living room floor. Meghan watched seriously, as the boys and I filled one of the boxes with canned goods and foods.

While I sorted through our clothes, I encouraged the boys to go through their toys and donate some of their less favorite things. Meghan watched quietly as the boys piled up old toys and games.

Meghan walked up with Lucy, her worn, much-loved rag doll hugged tightly to her chest. She came to the box that held the toys, pressed her round little face into Lucy's flat, painted-on-face, gave her a final kiss, then laid her gently on top of the other toys.

“Oh, Honey,” I said.” You don’t have to give Lucy. You love her so much.”

Meghan nodded seriously, eyes filled with held-back tears. "Lucy makes me happy, Mommy. Maybe she’ll make that other little girl happy,too.”

Paragraph. 1:

The boys had watched,open-mouthed,as their baby sister placed her favorite doll in the box.

7 . 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.

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.

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

D．MyShake Makes Earthquake Prediction More Accurate

8 . 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。

Koalas are among Australia's favourite animals.     1     (unlucky), they could disappear from New South Wales stale by 2050 according to the finding of an official investigation.

Koalas live in eucalyptus (校树)forests. The trees provide shelter and food     2     the koalas. They eat eucalyptus     3     (leaf). However, the state's most recent fire season,     4    (aid) by extremely dry weather, is unusually long and terrible for koalas. It is found that so far about 25% of koala habitat across the state     5     (destroy), in some parts as much as 81%.       6     is actions such as land clearing for fanning, city development, and deforestation (毁林) that are threatening the koalas' survival.

The result     7     (be) alarming. Only if the government acts on protective measures will our children's grandchildren see a koala in the wild. WWF calls on the government to make new laws     8     (protect) the koala habitat. Besides, more     9     (economy) support should be given to farmers who actively protect eucalyptus trees. The Premier of New South Wales said the government would do as WWF advises and take powerful measures in areas     10     the animals live.

9 . After an earthquake most survivors can be expected to recover over time, particularly with the support of family and friends. Some families will be able to return to their normal life quickly, while others will have to contend with the destruction of their homes, medical problems, and injury to family members. Children especially will need time to recover from the loss of a loved one or a pet or from the closing down of their school.

Children often turn to adults for information, comfort and help. Parents should try to remain calm, answer children’s questions honestly and remain understanding when they see changes in their children’s behavior.

Children react differently to an earthquake depending on their ages, developmental levels and former experiences. Some will respond by withdrawing (不与人交往), while others will have angry outbursts (爆发). Parents should remain sensitive to each child’s reactions. Parents should spend time talking to their children，letting them know that it’s OK to ask questions and to share their worries. Although it may be hard to find time to have these talks, parents can use regular family mealtimes or bedtimes for them. They should answer questions briefly and honestly and be sure to ask their children for their opinions and ideas. Issues may come up more than once and parents should remain patient when you answer the questions again. For young children, parents, after talking about the earthquake, might read a favorite story or have a relaxing family activity to help them calm down. Parents should also tell children they are safe and spend extra time with them. They could play games outside or read together indoors. Most importantly, be sure to tell them you love them.

1. The underlined phrase “contend with” in Paragraph 1 can be replaced by “________”.

A．deal with

B．make up

C．put off

D．turn back

2. When children ask the same question again, parents should ________.

A．read a favorite story to comfort them

B．ask them to help do some housework

C．be patient and answer the question again

D．take them out to play games

3. Which of the following pieces of advice is NOT mentioned in the passage?

A．Keep a close watch on children’s behavior.

B．Tell the children they are safe.

C．Tell the children you love them.

D．Ask educational experts for help.

4. What can we know from the passage?

A．All people will recover from an earthquake quickly.

B．Children may need a longer time to recover after an earthquake.

C．Children should turn to their classmates for help after an earthquake.

D．Children react in the same way as adults do to an earthquake.

10 . Social distancing is not a new concept in the natural world, where infectious diseases are commonplace. Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.

In 1966, while studying chimps (猩猩) in a Tanzanian national park, zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus. His fellow chimps attacked him and threw him out of the troop. In one instance, McGregor approached chimps in a tree. He reached out a hand in greeting, but the others moved away without a backward glance.

“For a full two minutes, old McGregor sat motionless, staring after them,” Goodall notes in her 1971 book In the Shadow of Man. “It’s really not that different to how some societies react today to such a tragedy.”

Not all animals are so aggressive toward their ailing neighbors. Sometimes it’s as simple as avoiding those who may infect you.

When Kiesecker, a lead scientist in America, studied American bullfrog in the late 1990s, he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs, but healthy members actively avoided those that were sick. Bullfrogs rely on chemicals signals to determine who is sick or not.

Caribbean lobsters also shun diseased members of their community, well before they become infectious. It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others. Normally social animals, lobsters begin keeping away from the diseased as early as four weeks after infection – once the lobsters can smell certain chemicals released by sick individuals.

Overall, it’s important to note that, unlike us, animals don’t realize if they stay home, they might actually reduce the infection rate,” Kiesecker explains. “As humans, we have that ability. It’s a big difference.”

1. What can we learn about the chimps from Goodall’s observation?

A．They kept a distance from one another.

B．They became aggressive when infected.

C．The infected avoided contact with others.

D．The infected were forced to leave the group.

2. What does the underlined word “shun” in Paragraph 6 probably mean?

A．Avoid.

B．Cure.

C．Get rid of.

D．Get along with.

3. How are humans different from animals according to Kiesecker?

A．Humans are more sensitive to virus.

B．Humans are less likely to get infected.

C．Humans treat infectious diseases in a wiser way.

D．Humans can detect chemical signals more quickly.

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

A．Help Me Out

B．Leave Me Alone

C．Stay Away From Us

D．Stay Home Stay Healthy
