Passage One
The cultural values of a society determine the social norms of the society. The SOCIAL NORMS are the group-shared rules of behavior. These norms are the expected ways of behaving in the society based on the shared values--the purposes and goals--of that society. For example, because we place some value on physical modesty, we have the social norm of wearing clothes in public. To be an accepted member of society, one must live by the rules which that society imposes. When an individual does not behave according to these norms, that person is considered a deviant. A person who walks down the main street of an American city with no clothes on is regarded as a deviant, that is, a person who does not follow the standard rules of behavior.
Some norms apply to all persons in a particular situation. For example, in our culture all persons are expected to be quiet in a library; obey the traffic signals; eat with a knife, fork and spoon; stand during the playing of the National Anthem ; and pay their bills. These are just a few of the many norms that every member of our society is expected to follow.
As used in this passage, a deviant is someone who ______.

Passage Two
If you’ve gone to the same seashore for several years, you may have noticed that the beach gets smaller every year. The wind and the waves carry the beach out to sea, bit by bit. Most shore towns try to fight the beach changes caused by ocean currents and the tides. Some dig sand out of backwater bays and dump it on the beachfront. Others build wooden piers and jetties made to keep currents away from the beach.
A type of artificial sand that has been developed might be able to slow down beach erosion. Strangely, this new kind of sand is made of ground glass! You might think that walking barefoot on ground glass would be painful. But it’s not. The reason is very simple. Sand and glass are made of the same kind of material, called silicate. When glass is ground very finely, you get a sand-like substance that is harder than real sand. The size of the pieces can be controlled. Larger pieces won’t be as easily affected by the wind and waves. So, a beach covered with artificial sand would last longer than a beach with real sand.
A wonderful thing about artificial sand is that it can be made from waste glass. But making artificial sand costs three times as much as using conventional methods of beach protection. So, it is not likely that sand made of glass will be used in the near future.
The subject of this passage is ______.

A．summer vacations
B．the seashore
C．artificial sand
D．sand and water

Passage Three
On October 17, 1829, Sam Patch did what he had said he would do. He perched on a platform built beside Niagara Falls, and jumped into the river a hundred feet below. A big crowd had gathered to watch Sam’s well-advertised leap. The spectators held their breath as the daredevil hit the swirling water. At last his head burst out of the foam, thirty feet clear of the falls. The crowd let out a mighty roar. Men waved their hats and yelled out the expression that had become Sam’s trademark : "There’s no mistake in Sam Patch!"
Sam began his career as a leaper in 1827, when he jumped eighty feet into the Passaic River, from a bridge that was still under construction. He was delighted with the notoriety he received. He traveled from town to town, jumping from masts, cliffs and bridges. Then he made his great conquest of Niagara Falls.
Sam was spurred on by the widespread public excitement over his successful leap from the Fails. He turned to the higher Genesee Falls for his next feat. On November 13, a scaffold was constructed 125 feet above the base of the Falls. A huge crowd gathered on both river banks. At 2:00 pro, Sam climbed the shaky scaffold, made a brief speech, and jumped. Once again there was hushed silence as his body smacked the water. But this time Sam didn’t resurface.
Sam’s body was pulled from the mouth of the river the following spring. Even so, for years afterward, a legend persisted that tile great Sam Patch was still alive.
What is the general idea of the passage

A．Genesee Fails is a dangerous place.
B．Sam Patch jumped at Niagara Falls.
C．There’s no mistakes in Sam Patch.
D．Sam Patch was a popular leaper.

Passage Four
Unless you have visited the southern United States, you probably have never heard of kudzu. Kudzu, as any southern farmer will sadly tell you, is a super-powered weed. It is a strong climbing vine. Once it gets started, kudzu is almost impossible to stop. It climbs to the tops of the tallest trees. It can cover large buildings. Whole barns and farm houses have been known to disappear from view. It has even been said to engulf small, slow-moving children, but that is probably an exaggeration. Still, wherever it grows, its thick, twisting vines are hard to remove.
Kudzu was once thought to be a helpful plant. Originally found in Asia, it was brought to America to help fight erosion. It was planted where its tough roots, which grow up to five feet long, could help hold back the soil. But the plant soon spread to places where it wasn’t wanted. Farmers now have to fight to keep it from eating up all the nutrients in the soil and killing other plants. It has become a sign of unemployment in the South; where there is no one to work the fields, kudzu soon takes over.
The northern United States faces no threat from kudzu. Harsh winters kill off its vines. It loves the warmth of the South. But the South surely doesn’t love it. If someone could invent some use for kudzu, and take it off southern farmers’ lands, their fortune would be assured.
This passage is mostly concerned with ______.

A．kudzu
B．farming
C．the South
D．soil erosion

Passage Five
There are many commonly held beliefs about eyeglasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have the wrong glasses.
We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes pool eyesight, but that is unique. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. But, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight.
Another myth about eyes is that they can be replaced, or transferred from one person to another. There are close to one million nerve fibers that connect the eyeball to the blain, and as if yet it is impossible to attach them all in a new person. Only certain parts of the eye--the cornea and the retina-- can be replaced. But if We keep clearing up the myths and learning more about the eyes, someday a full transplant may be possible!
This passage is mostly about ______.

A．different types of eyeglasses
B．a visit to the eye doctor
C．myths about eyesight
D．cornea transplants
