After winning a big game，athletes are often asked how they feel．Usually athletes say how  36 it is to win this big game．On the contrary，the fact is that losing a big game，or in my case，all the games，can be even harder．
From the spectators’ point of view，last year’s basketball  37  for my high school team was nothing  38 of an embarrassment．And  39  0 and 20 is certainly nothing to be proud of，that season had a bigger impact on me than any other．As a team captain，I knew it probably wouldn’t be the  40 year，but did I ever think we would lose every game？Of course not．Since six of our top players had graduated，it was clear that we were a (n)  41  team who would struggle．The struggle began earlier than expected，  42 ，as our team center was suspended (禁赛) for the season，and two key members decided to  43  for some reason．At this point，dropping out probably passed through every player’s mind，but in the end，we all stuck if out，  44 to work still harder．
Then there came a time when even our  45 and given up on us．Personally，I felt like it was  46 worthwhile giving my all．I thought，if even the coach doesn’t believe in us，whyshould I？But just as my hope began to  47 ，a teammate called a meeting．He said，“Nobody thinks we are going to win，but，as teammates and friends，we  48 it to each other to go all out every game．”
It was that moment that  49  me how to be a leader．It hit me that I certainly didn’t 50  the role．As a leader you can never quit  51  the team who looks up to you．It is one  52 to be named captain，feel great and go through the motions，but it is quite another to be a real captain and make sure everyone realizes their full  53 all the time．
I am sure it is great to go through without losing and bringing home awards．But in all honesty，I  54 the fact that my team lost every game last year．It may not help me to become a better basketball player，but it already has made me a better leader，and  55 ．

B
Save the Animals
Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers(羽毛), for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks (鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied (繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws prohibit the killing of any animal or plant on the danger list.
61. Animals are important to us mainly because __________.
A . they give us a source of food             B. they are beautiful and lovely
C. they keep the balance of nature            D. they give us a lot of pleasure
62. What has happened to the animals on the earth?
A. About 170 kinds of animals have disappeared forever.
B. Thousands of kinds of animals are gone forever.
C. A few kinds of animals have died out.
D. All kinds of animals are in danger.
63. Why do people kill animals?
A. They kill animals for something they need.
B. They kill animals to raise some money.
C. Animals destroy their natural resources.
D. Animals create many problems.
64. What does the underlined word “prohibit” mean in the last paragraph?
A. prevent           B. stop              C. forbid            D. allow
65. What can we infer(推断) from the fact that quite a few countries have passed laws protecting animals in danger?
A. Animals in danger will be kept away from people.
B. Animals in danger will not be killed any more.
C. The number of some animals in danger will increase.
D. Every person will know the importance of protecting wild animals.

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

1.．According to the new findings, taking steps to prevent northern forest fires may __________.

2.．The following are all the immediate effects after a forest fire EXCEPT __________.

3.．Earlier studies about northern forest fires __________.

4.．The underlined phrase “soak up” in the last paragraph most probably means __________.

5.．From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ____.
