All penguins (企鹅) swim in cold waters and so need a good layer of insulation (隔离), some species come ashore in hot places.Humboldt penguins,for example,nest in arid hot - 40°C, deserts on the west coast of South America, while others survive the lowest temperatures of any animals.Male Emperor penguins,as we know, spend the Antarctic winters incubating eggs in temperatures that can fall below -70°C. The insulation is provided in layers, under the skin is a thick layer of fat, then there is a layer of downy feathers that trap air, and finally another layer of waterproof feathers that keep the cold water away from the skin. With all this insulation penguins have no problem keeping warm at temperatures down to about -10°C - although they have special adaptations of the circulatory system to keep their feet from freezing and to prevent much heat loss through the feet that are on the ice. At lower temperatures penguins have to huddle (蜷缩) together to keep warm. In such huddles the penguins gradually move from the hot interior to the cold outside so that every penguin has his turn in the middle and on the outside.
In hot climates, penguins suffer greatly from overheating. They use several strategies to lose heat. They puff up their feathers so that air can circulate to their skin; they hold their flippers（脚蹼）out from their bodies and pump hot blood to them so that they can act as radiators; they open their mouths and breathe to lose heat from their hot breath; and those species that live in hot climates also have several bare patches of skin around the eyes and feet, they send blood to these bare patches when they are hot - you can recognize a hot penguin since it will have pink eye patches and pink patches on its feet.
77. Which of the following are the ways for penguins to keep warm?
a. staying together in good social order 
b. several layers as radiators
c. a special circulatory system                    d. waterproof feathers
e. sending blood to bare patches
f. always staying in the middle
A. a, b, c                    B. a, c, d                    C. b, c, e                    D. c, d, f
78. The insulation consists of _______ layers.                                       
A. two                        B. three                      C. four                       D. five
79. The underlined "puff up" in the second paragraph can be replaced by ______.
A. breathe deeply         B. blow up                 C. hold tight               D. spread out
80. The passage mainly tells us ______.
A. how penguins stay warm in cold places       B. that penguins are a clever animal
C. how penguins keep their temperature          D. why penguins can live a safe life

Once "Boggs dollars " have been given away by the artist,they often continuew to circulate and grow on value A "Boggs one dollar bill" may have bought the artist a cup of coffee in New York.Now it may be worth a car or an expensive meal.It all depends on that value a person chooses to give it.

第三部分：阅读理解（共20小题；每小题2分，满分40分）

阅读下列短文，从每篇短文后所给的四个选项（A、B、C 和 D）中，选出最佳选项，并在答题卡上将该项涂黑。

Steve Wayne, 16, who worked this summer as a lifeguard and swim teacher in Idaho Falls, was thrilled to see an extra $ 20 in his paycheck when the federal minimum wage increased in July.

“When you’re getting paid minimum wage, anything helps,” Wayne said.

Wayne is one of several hundred thousand American teenagers who earn the minimum wage. The last of three recent increases took the minimum from $5.15 an hour in 2007 to $7.25.

US Secretary of Labor Hilda Solis says the minimum-wage increase will pump an extra $ 5.5 billion into the economy over the next year, which is helpful at a time when the economy is hurting.

“You’re giving people who spend money a raise,” said Kai Filion of the Economic Policy Institute. “Those people will go out and spend that money, and it will circulate through the economy.”

But other economists say raising the wage actually hurts the very people it’s designed to help. A higher hourly minimum, they say, could force businesses to cut workers’ hours, or even lay people off.

“What matters for people earning minimum wage is how much money they take home in total,” explained Rajeev of Georgia State University’s Economic Forecasting Center. “Their hourly rate may go up, but their number of hours may come down, so it’s not an overall increase.”

Business owners also say that raising the minimum wage exerts (施加) upward pressure on other wages. “If the minimum wage is $ 7 and I have to pay $ 8 or $ 9 to hire a dishwasher, then the cooks are going to say they want more,” said Cleveland restaurant owner Rick. “How much can I charge for that hamburger?”

Another argument is that it makes it more expensive for businesses to hire new workers. For many businesses already struggling to make ends meet in these tough times, it will be simply too expensive to keep them or to hire new people.

1. Steve Wayne was excited that ______.

A. his hard work had paid off

B. he had received a big wage increase

C. he has more money due to an increase in minimum wage

D. the wages of American teenage workers have been increased

2. According to the text, the US federal government has increased minimum wage with the aim of ______.

A. decreasing unemployment                             B. promoting economic recovery

C. increasing American teenagers’ wage        D. narrowing the gap between the rich and the poor

3. What matters most to people in need of help is ______.

A. a higher hourly minimum                  B. more working hours

C. a minimum-wage increase                D. an increase in total income

4. Some are against the increase in minimum wage because they say ______.

A. only very few workers will be helped

B. they have to cut down working hours

C. many business owners can’t afford to employ new workers

D. minimum wage workers will expect more pay rises in the future

These fairy tales are as popular as before in that they _____ the common sense of justice and equality.

    A. circulate        B. observe          C. satisfy          D. deliver
