2 . 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.

Nature inspired us to figure out ways to solve the problems we faced. Birds inspired us to fly, beavers gave us ideas on how to build dams (大坝) and even tiny white ants demonstrated building ideas that we could use. By means of     1    (study) the workings of wildlife, we've come up     2     some pretty brilliant inventions. Here' re some examples to inspire students to explore their own ideas.

Bats (蝙蝠) can use     3    (they) mouths and ears to identify high-frequency sound waves, allowing them to avoid barriers and catch insects in the air. They do this by making sounds     4     can be reflected off a surface in a process     5    (call) echolocation. It is no big surprise that researchers are working on ways that poor-sighted people can use a system like echolocation.

Spider (蜘蛛) silk is one of the strongest materials in nature, believed to be five times     6    (strong) than steel. But unlike steel, spider silk is both flexible     7     lightweight. Scientists recently created a new type of medical tape based on the features of spider silk.

Even plants can inspire invention.     8     electrical engineer named George de Mestral noticed that burrs from burdockplants (牛蒡植物的芒刺) stuck fast to his unfortunate hunting dog. From that bit of inspiration, he invented Velcro, one of the most     9    (wide) used fastening systems in human history.

Students should     10    (encourage) to study the characteristics of a plant or animal and see what inventions or ideas they can design.

3 . Once there was a dandelion (蒲公英) living alone by the road. It felt bored and sad all day as no one ever stopped to take a look at or talk to it.

One day, a mother was walking on the road with her baby. The baby was crying hard and loudly. No matter what the mother did, she couldn’t get the baby to stop crying. Then the mother looked down, and she found the lonely dandelion. It looked so lovely in the sun with its white seeds widely open, and more beautiful than other plants around.

The mother squatted down, (蹲下) picking the dandelion softly. Then she brought it up to her baby so that he could see it clearly. When the baby saw the flowers of the dandelion, he quickly stopped crying and looked at them with interest.

His mom put the dandelion near her mouth and blew the flowers up and down. The dandelion seeds then flew in the air, spreading far away with the wind. The mother gave the dandelion to her son. He didn’t know what the plant was, but he knew it was fun to play with, which made him giggle (咯咯笑) so happily.

Now the dandelion knew its value and didn’t feel sad. It lived a beautiful life just by being itself. It wasn’t as beautiful as other flowers, but it brought the child a simple kind of happiness that money can’t buy.

The dandelion’s story tells us that everyone is special and great. We can help others in one way or another. We’re far greater than we think we are.

1. Why did the dandelion feel lonely at first?

A．Because no one noticed it .	B．Because it left its mother.
C．Because it lived by the road.	D．Because it had no friends.

2. Which words can best describe the mother?

A．Kind and honest.	B．Friendly and helpful.
C．Patient and careful.	D．Beautiful and funny.

3. The dandelion felt happy at last because_______.

A．it could travel farther	B．it found its value
C．it was powerful again	D．it had more seeds than before

4. What does the story tell us?

A．Great minds think alike.

B．Two heads are better than one.

C．Rome was not built in a day.

D．All things in their being are good for something.

4 . There has been a very serious decline in the numbers of shallow-water fish as a result of overfishing. People still want to eat fish, so the fishing industry must look at other sources, especially the deep waters of the Atlantic.     1    

Conservation measures will have to be put in place if these deep-sea fish are to survive. Research on five such species shows that numbers have declined by between 87 percent and 98 percent.     2     Many species could well disappear completely if the present trend continues. These are species that have been swimming in our oceans for hundreds of millions of years.

The problem is emphasized by the fact that the decline in numbers happened in less than twenty years. Deep-sea fish take a long time to reproduce and normally live for many years.     3     The average size of such fish also declined, with one species showing a 57 percent decline in average size. This is of particular concern, as large fish tend to produce more offspring than small ones.

    4     The deep-sea species have been caught as if they were the fast-breeding (快速繁殖) fish like sardine and herring. It is like killing elephants as if they reproduced at the same rate as rabbits.

The damage done by overfishing goes beyond the sea environment. Millions of people make a living in the fishing industry.     5     Measures must be taken to not only conserve ecosystems, but also sustain livelihoods and ensure food security.

A．Billions of people rely on fish for protein.

B．Many people now choose not to eat deep-sea fish.

C．Unfortunately, their reproduction rate is very low.

D．This puts them in the category of “critically endangered”.

E．None of these facts has been taken into account by the fishing industry.

F．Overfishing is a major cause of decline in populations of ocean wildlife.

G．This has resulted in a sharp decline in the numbers of many of the species caught.

5 . The Sahara Desert

Location

Filling nearly all of northern Africa, the Sahara Desert measures approximately 3, 000 miles from east to west and between 800 and 1, 200 miles from north to south.     1     The Sahara Desert is bordered in the west by the Atlantic Ocean, in the north by the Atlas Mountains and the Mediterranean Sea, in the east by the Red Sea, and in the south by the Sahel.

Landscape

The Sahara Desert features iconic sand dune (沙丘) fields, which cover about 15 percent of the entire desert’s surface and lie primarily in the north-central region.     2     A few examples include crescent (新月形的) dunes, linear dunes, transverse dunes and star dunes. These dunes, with their various forms, raise many questions about the dynamics of their formation.

Water

    3     Its age-old rivers are the Nile and the Niger. The Nile rises south of the Sahara and empties into the Mediterranean. The Niger rises southwest of the Sahara and flows northeastward into Mali.     4     It is the expansive but shallow Lake Chad, a body of water that lies at the southernmost edge of the Sahara. Other lakes hold a salty stew of undrinkable water.

Climate

Across the Sahara Desert, the annual average rainfall equals no more than a few inches or fewer. In the summer, daytime air temperatures often soar to over 100 degrees Fahrenheit, with the hottest air temperature meteorologists have ever recorded — 136 degrees — occurring at EL Azizia, Libya, on September 13, 1922.     5     In the winter, freezing temperatures may occur in the northern Sahara Desert, and milder temperatures across the southern Sahara Desert. Snow may fall occasionally in some of the higher mountain ranges and rarely, on the desert floor.

A．No rain at all may fall for several more years.

B．It has a total area of some 3,320,000 square miles.

C．The dunes usually take on varied and complex forms.

D．Star dunes form under winds that blow from several directions.

E．The Sahara Desert has some lakes, but only one with drinkable water.

F．The Sahara Desert has only two permanent rivers and a handful of lakes.

G．Under the clear skies, the temperature may fall 40 degrees or more during an evening.

The program ________ local neighborhood groups called Banjars that collect plastic from their homes, streets, rivers, beaches and surrounding areas. Villages hold community exchange ________ once a month in which residents can bring in plastic to trade in for rice. Yasa says the organization has so far helped ________ thousands of families and collected ________ 300 tons of plastic for recycling.

7 . 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。

A freezing downpour washed the street in front of the small-town bar. I sat gazing into the watery darkness, alone as usual. I had been in that old bar for half an hour, quietly drinking, when my thoughtful eyes finally focused on a medium-sized lump (一团) in a puddle (水洼) a hundred feet away. For another ten minutes, I looked out through the window trying to decide if the lump was an animal or just something.

The night before, a German dog named Shep had come into the bar begging for potato chips. He was starving and just the size of the lump in the puddle. Why should a dog lie in a cold puddle in the freezing rain? I asked myself. The answer was simple: Either it wasn’t a dog, or it was, he was too weak to get up.

The wound in my right shoulder ached all the way down my fingers. I didn’t want to go out in the storm. Hey, it wasn’t my dog. It was just a stray on a cold rainy night, a lonely drifter (流浪者). So was I, I thought, as I tossed (扔) down what was left of my drink and headed out the door.

He was lying in the three inches of water. When I touched him, he didn’t move. I thought he was dead. I put my hands around his chest and raised him to his feet. He stood unsteadily, and his head hung like a weight at the end of his neck. His floppy ears were just hairless pieces of flesh dotted with open sores (伤口).

“Come on, Shep,” I said, leading him to a corner next to the bar, where he lay on the cold cement and closed his eyes. A block away I could see the lights of a late-night convenience store. It was still open. I bought three cans of dog food and fed him. He couldn’t swallow but poorly look at me. He was dying!
