Football, to me, is more than just a game. I have probably learned more than valuable lessons from it than from school.
When I joined the team freshman year, I didn’t realize what I was getting into. Even though I had been playing since fourth grade and knew it was hard work, nothing would prepare me for the effort I would put into football that year. We worked all summer in the weight room and ran on the track to get in physical and mental shape before the season.
See, football is more of a mental sport than anything else, so running on the track wasn’t only about getting in shape . We would push our minds by running as hard as we could even if we felt like we were going to pass out. At the beginning, I was immature (幼稚的) and only thought of myself, sometimes even giving up when I was tired or hurting. Then after the third game I had a season-ending injury. Imagine working all summer and then only being able to play three games! I needed surgery on my arm and at least five months to recover.
After freshman year I decided that I would always give my best effort. Playing varsity (大学代表队) football has taught me so much more than just what my tasks are on a particular play or how to block. I have learned to think about others first, and realized how important working hard is. Being with all my friends, even sweating and bleeding with them, really made us unite as a group of hard-working young men, who will succeed in life.

Yawning sends out certain messages -either “Oh ，this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?

A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.

The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.

When people yawn, their jaw is also stretched ，which increases blood flow and may also help cool the brain

The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.

However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.

According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.

1.The purpose of the experiment is ______.

A. to prove people yawn in winter and in summer equally

B. to indicate brain can regulate temperature naturally

C. to find the frequency of people’s yawning

D. to show the real reason why people yawn

2.The information we get from Paragraphs 5 and 6 is that ______.

A. longer outdoor summertime results in more yawns

B. yawning frequency changes with outdoor time

C. yawning frequency increases with outdoor time

D. longer outdoor wintertime leads to fewer yawns

3.Acorrding to the text ，people yawn more often ______.

A, when the air temperature is lower outside the body

B. when the hot air breathed in makes the brain hotter

C. when the air temperature is higher than the body

D. when the air temperature is equal to the body

4.What could be the best title for the text?

A. Yawning Is A Sign of Brain Disease

B. Yawning Carries Some Information

C. Yawning Benefits Your Body

D. Yawning Cools Your Brain

When nature is left alone, a balance is reached among the animals and plants living in one area. But when man starts his work in nature, the balance is likely to be destroyed. He grows a crop and takes it away to eat ;then there are no dead leaves to fall on the ground, holding water while it sinks into the surface, or decaying (腐烂) and adding humus (腐殖质) to the soil. Unless a farmer acts with knowledge and skill, he is therefore most likely to make the land poorer. To take the place of the useful matter in the crops that he removes, he uses some kind of fertilizer (肥料). Chemical fertilizers are of great help, but the waste products of animals and decaying remains of plants should also be put on the land. In some places, it is a habit to burn waste material lying about, but such burning destroys the useful matter in the dead plants. Although the ashes that are left are valuable when put on the land, a better practice is to bury the waste so that it decays and increases the humus in the soil.

In the past, when the world population was much lower than it is now, a man had little difficulty in ordinary times in growing the food that was needed. When a field had been used some years and had become tired, the farmer could move to another place. The tired land then slowly recovered. By and by grasses and other plants would appear on it and its productive power would slowly return to normal through their decay. But nature, left alone, would take a long time to bring back the land to its former state; the length of time required would depend on local conditions, but it might well be ten years.

It is a bad practice to grow the same crop in a field year after year. If the crop is changed, the land will suffer less because it is treated and used in a different way. Different plants have different effects on the soil. Therefore, a change of crop will do less harm than the growing of the same crop year after year and a regular change to grass will do good to the soil. Much will therefore be gained if different crops are grown one after another, a method known as the rotation (轮作) of crops.

1.According to the passage, the land will become poorer ( )

A. if all the dead leaves are cleared away B. if the humus is increased after the harvest

C. if dead leaves decay in the soil by themselves D. if waste plant material lying about is buried

2.We can learn from the passage that the tired land has slowly recovered ( )

A. when grasses and other plants appear again

B. when the treatment is given by nature alone

C. after new grasses and other plants have decayed again

D. after nature has been left alone for several months

3.A modern farmer can hardly move to another place as he did before because ( )

A. the productive power of a new field isn't higher than that of an old one

B. there are few free fields left for him to do farming

C. it takes a farmer more than ten years to start farming in a new field

D. there will be too many grasses in a new field to grow crops

4.It is most likely that the author will go on to ( ) in the paragraph following the passage above.

A. introduce other methods of planting crops B. deal with how to prevent land getting tired

C. start another topic of how to make use of land D. further explain what the rotation of crops is

What do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it?

The first thing to remember is that the sea is very big. When you look at the map of the world you will find there is more water than land. The sea covers three quarters of the world.

The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot, near Japan, where the sea is nearly 11 kilometers deep! The highest mountain in the world is about 9 kilometers high. If that mountain were put into the sea at that place, there would he 2 kilometers of water above it ! What a deep place !

If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers, which flow into the sea, carry salt from the land into the sea. Some parts of the sea are saltier than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot sink! Fish cannot live in the Dead Sea!

In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them. Many fish live by eating these.

The sea can be very cold. Divers who go deep down in the sea know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometers !

1.When does the sea look beautiful?

A. When it is calm. B. When the weather is fine.

C. When there is a strong wind. D. When there is a storm.

2. How much of the earth’s surface does land cover?

A. 15%. B. 25%. C. 30%. D. 45%.

3.Why does the writer cite（引用） the sea somewhere near Japan?

A. To show that the sea in some places is very deep.

B. To show that the sea in some places is very shallow.

C. To show that its depth is 9 kilometers greater than the height of the highest mountain.

D. To show that its depth is 11 kilometers greater than the height

of the highest mountain.

4.Which of the following statements about the Dead Sea is NOT true?

A. Swimmers cannot sink. B. It is a safe place for swimmers.

C. It is extremely salty. D. Fish can be found in it.
