完形填空

　　I like to be near water--sea, lake or river. That is probably 1 I was born in a village by the sea, and have lived most of my life close to water of 2 . When I am in some place which is 3 lake, river and sea. I am 4 and always feel that there is something missing 5 it is sometimes hard for me to decide what it is.

　　Of course, the sports I like are ones which 6 water--sailing, rowing and swimming, It is 7 to swim in small swimming-pools, but rowing and sailing are impossible 8 a lot of water. Rowing is best on a river, 9 sailing on the sea or a big lake, but 10 can do some sailing on a river, and one can 11 row on a lake or the sea when the weather is good.

　　Of the three sports--swimming, rowing and sailing, I like 12 best, because it is the easiest to 13 during the winter, when the water is too cold for 14 swimming and the sea is often too rough for sailing. 15 on the coldest days one can row: only hard 16 on the water, or thick fog stops one. Sometimes it is so cold when I go out rowing that 17 of water freeze wherever they fall. In such 18 , it is not very pleasant to swim: one cannot stay in the water very long; 19 , when one is rowing, one gets warmer the 20 one goes on.

Homemade Ice Cream in a Bag
Difficulty: Very Easy
Average User Rating:★★★★☆(4.3/5)
Milk can become homemade ice cream in five minutes by using a bag! This homemade, creamy treat is a summertime delight for your kids and you alike.
What you’ll need:
1 tablespoon of sugar; 1/2 cup of milk; 1/4 teaspoon of vanilla (香草香精); 6 tablespoons of rock salt; 1 small-sized plastic food storage bag; 1 gallon-sized plastic food storage bag; ice cubes.
How to make it:
l Fill the large bag half full of ice, and add the rock salt. Seal the bag.
l Put milk, vanilla, and sugar into the small bag, and seal it.
l Place the small bag inside the large one, and seal it again carefully.
l Shake until the mixture turns into ice cream, which takes about five minutes.
l Wipe the top of the small bag, and then open it carefully. Enjoy!
Tips:
1/2 cup of milk will make about one spoon of ice cream, so double the recipe if you want more. But don’t increase the amount more than that—a large amount might be too big for kids to pick up because the ice itself is heavy.
Here is another version of the homemade ice cream recipe from another parent!
These are the homemade ice cream ingredients:
1/4 teaspoon of vanilla butter and nuts; 1 tablespoon of sugar; 1/2 cup of milk.
These are the other supplies:
Plastic sandwich bag; 12 salt pellets; 1 dish of ice; large plastic bag.
Put the ice cream ingredients in the small bag, and then put the bag, salt and ice in the big bag. Hold the bag shut and move it around on the floor for about 5 minutes.
When I made ice cream at home last time, although the salt pellets didn’t really dissolve (溶解) that well, I still got ice cream. It was not smooth ice cream, probably because of the low-fat milk. It was incredible that it could be ready in 5 minutes (not counting preparing the ingredients)
Next, I changed the recipe, using a tablespoon of cocoa, a tablespoon of sugar, and a cup of milk. It was a bit too chocolaty, but good!
【小题1】The underlined “that” in “Tips” section refers to ____.

Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point. The fish were taken from seawater that had a temperature of -1.88°C and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05°C. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.
【小题1】 What is the text mainly about?

Some scientists warn that ice near the Earth’s Poles may indeed be melting. This “polar meltdown” may be the first sign that the Earth is heating up. We could be in very serious trouble if this trend continues. It is estimated that a meltdown of as little as 10 percent of Antarctica’s ice would raise sea levels around the globe by 4 to 9 meters. Floods would cover low-lying regions and turn coastal cities like New York and New Orleans into real life underwater world.

Scientists first predicted in the 1970s that heat trapped in the Earth’s atmosphere could cause a polar meltdown. Many now believe that human activities are turning up the heat. When we burn fossil fuels like coal and oil, we add carbon dioxide(CO2) gas to the Earth’s atmosphere. Cutting down trees also makes CO2 levels raise because trees normally soak up CO2 to make food. Scientists say higher CO2 levels strengthen the “greenhouse effect” and could increase the Earth’s temperature. In fact, CO2 levels have risen by 30 percent since the Industrial Revolution of the 18th and 19th centuries.

Over the past three years, satellite measurements have shown a sea level rise of about a quarter inch worldwide. “If nothing is done to reduce fossil-fuel pollution and global warming, sea levels will rise even more.” says geologist Richard Alley.

But even Alley admits that a polar meltdown would take time. The ice in Antarctica and Arctic locks up nearly nine times the volume of water contained in all the world’s rivers and lakes. These are such big “ice cubes” and it would probably take thousands of years to melt them.

Another scientist Charles Bentley doesn’t think a meltdown will happen at all. “Even if warmer temperatures begin to melt polar-ice,” he says, “the excess moisture would most likely be redeposit as snow.” In other words, the melted ice would evaporate into the atmosphere, refreeze, and fall as rain and snow over the Poles.

What consequence of global warming is mentioned in the passage?

A. More tropical storms.       B. More tropical diseases.

C. Changes in farm productivity.   D. Coastal flooding.

Which of the following statements does the second paragraph support?

A. CO2 in the atmosphere cannot keep the heat from escaping into space.

B. The increase of CO2 gas may warm the planet and help to melt polar ice.

C. Cutting down trees helps to greatly reduce CO2 levels.

D. The end of the short-lived age of fossil fuels is already in sight.

Geologist Richard Alley most likely agrees that _______.

A. the sea-level rise can be prevented by cutting back on energy-consuming activities

B. the recent breaking off of ice blocks from Antarctica is just a natural part of a long-term cycle

C. Antarctica temperatures have significantly changed since the Industrial Revolution

D. the polar meltdown may be an accidental change of climate rather than a sign of global warming

Charles Bentley believes that a polar meltdown will not occur because _______.

A. governments around the world are beginning to reduce CO2 levels in the air

B. a melting of the polar ice cannot be achieved with the present technologies

C. the melted ice in the polar areas would change into snow and rain over the Poles

D. the sun’s heat would have no chance of being absorbed by the polar ice

In which paragraph does the author mention the immense quantities of polar ice?

A. In the second paragraph.   B. In the third paragraph.

C. In the fourth paragraph.    D. In the fifth paragraph.
