At first, the earth’s surface(表面) layer (层) was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles (卵石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones. Wind, water. heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks (裂缝) in the rock, which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces.
The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the carcks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces.
According to the passage, soil ______ .

A.forms very slowly
B.is a mixture of stones, pebbles and sand
C.makes up the layers of the earth
D.is becoming smaller and smaller

Which of the following is NOT true?

A.The remains of many plants and animals formed soil.
B.If a large rock never moves, it will never break up.
C.Even if a large rock never moves, it will break up.

It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver's seat is another matter altogether.
Road politeness is not only good manners, but good sense too. It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions. But such behaviors of politeness are by no means enough. Many drivers nowadays don't even seem able to recognize politeness when they see it.
However, misplaced politeness can also be dangerous. Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to. It always amazes me that the highways are not covered with the dead bodies of these grannies
An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can't even learn to drive. Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart.
According to the passage, troubles on the road are often caused by ________.

A.road conditions B.the speed of modern life
C.the large number of cars D.the behavior of the drivers

In the writer’s opinion, ________.

A.drivers should show road politeness properly.
B.strict traffic rules are badly needed.
C.unskillful drivers should be punished.
D.drivers should avoid traffic jams.

The underlined word “give-and-take” in the passage means________

A.politeness and impoliteness
B.willingness to give in to each other’s wishes.
C.offering help to others as much as possible.
D.good manners and bad manners.

What is the best title of the passage?

A.Road politeness B.Traffic problems
C.Bad Manners on the Road D.Good Drivers and Bad Drivers

I moved from Chicago to Brooklyn in July of 2010, just in time to watch my mother die. Our parents were both gone now. I took with me as many things they had left behind as I could.
I was out walking one Saturday later that summer when something caught my eye - a pale green dress. Laid out on the pavement was stuff like earrings, glass candle-holders, books. Hanging on the fence behind were a few pairs of jeans and a green cotton dress.
The woman, the host of the stoop (门廊)sale, looked like she was getting rid of a past she didn’t need or want. A dress that was too big for her. A chest of drawers that took up too much space, space she needed, maybe, to heal , recover, or grow.
I wasn’t planning on buying anything really, but now I needed to show her that I appreciated her things and I would give them a safe home. Then I had my first stoop sale —I paid her 20 dollars for her green cotton dress and her blue candle-holder.
From that day on, I became interested in stoop sales. Some of my favorite things are from someone else’s life. I find no joy in shopping at regular stores any more. I love trying to sniff out a memory from a bud vase or a drawer. It is comforting to know that someone has breathed and laughed inside a sweater before me.
A few weeks ago, I carried my mother’s dresses to a friend’s stoop. These were her best items, which were once worn by the most important person in my life. For many hours, I watched from across the path people advancing the stoop, some leaving with Mom1S dress. I used to think that her stuff was as forever sacred (神圣的)as my memory of her, I know now that once I love a scarf or shirt too dearly, it needs to find a new home. Even that green dress is long gone by now.
The author took her mother’s dresses after her death because ______

A.she valued the things used by her mom
B.she didn’t want to throw them, away
C.she could sell them later
D.they were her mom’s best items

From the passage, we know that ______.

A.the things the author bought from the woman are too big
B.the author is fond of imagining others’ life experiences
C.the author will never shop at regular stores any more
D.the author still keeps most of her mom’s things

In the last paragraph, the author tries to tell us that ______.

A.her mom is the number one person in her life
B.she didn’t really want to sell her mom’s dresses
C.she still thinks of her mother quite often
D.love doesn’t mean holding on to something tightly

It can be inferred that the author will ______.

A.not sell her own things at stoop sales
B.keep her mom in her mind in another way
C.be sad about all the memory of her mom
D.move to another city for a new life

Should we allow modern buildings to be built next to older buildings in historic area of a city? In order to answer this question, we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons—for example, economic(经济的) reasons—why they should be preserved. So, let us assume that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?
In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own home town of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not dominate(影响)its surroundings too much, it often improves the attractiveness of the area.
It is true that there are examples of new buildings which have spoilt(破坏)the area they are in, but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative (保守的)and do not like change.
Although we have to respect people's feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move_things_forward. If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different, even though that might be the more risky choice.
What does the author say about historical buildings in the first paragraph?

A.Most of them are too expensive to preserve.
B.Some of them are not attractive.
C.They are more pleasing than modern buildings.
D.They have nothing to do with the historic feel of an area.

Which of the following is true according to the author?

A.We should reproduce the same old buildings.
B.Buildings should not dominate their surroundings.
C.No one understands why people speak against new buildings.j-y
D.Some old buildings have spoilt the area they are in.

By “move things forward” in the last paragraph, the author probably means “________.”

A.destroy old buildings
B.respect people's feelings for historical buildings21
C.put things in a different place
D.choose new architectural styles

What is the main purpose of the passage?

A.To argue that modern buildings can be built in historic areas.
B.To explain why people dislike change.
C.To warn that we should end up living in caves.
D.To admit how new buildings have ruined their surroundings.

Americans plan parties for many reasons. As in other cultures, many Americans attend parties for weddings and religious or national holidays. But some parties are especially American. For example, a group of neighbors may gather on their street to eat food, play music and visit with one another. This is called a block party. A woman might invite a group of women to a party called a baby shower for a friend who is about to give birth. Guests bring presents for the new baby.
Americans also attend tailgate parties. A tailgate is the back end of a truck or other vehicle that opens down. The tailgate parties are a big part of sports culture in the United States. Friends bring food and drink to a sports event. They eat together in the parking area of the sports stadium.
Birthday parties are also very popular. Many parents organize a party for their child around a theme. Birthday parties usually include gifts and a birthday cake with candles. In many parts of the United States, cupcakes have become a popular replacement for cakes.
Birthday parties can be low cost or very costly. Some parents take their children’s birthday parties very seriously, even when the child is too young to fully understand the celebration.
One group of parents started a website called Birthdays Without Pressure. They decided that some parents were under too much social pressure to plan costly parties for their children. The group sees this movement as an example of America’s culture of “too much stuff”. The group’s website gives suggestions on how to keep birthday celebrations simple, meaningful and fun without spending a lot of money. Their advice may be very helpful during this period of economic recession (萧条).
What can be the best title for the passage?

A.Reasons for parties B.Birthdays without pressure
C.Different parties in the world D.American parties
