Man-made Causes

Man-made causes probably do the most damage. There are many man-made causes.  21  is one of the biggest man-made problems. Pollution  22  in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil(化石) fuels(燃料)are fuels made of organic matter such as coal, or oil. when fossil fuels are burned they  23  a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane(甲烷)is  24  in the ground.  25  coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.

Another major man-made  26  of Global Warming is population. More people  27  more food, and more methods of transportation, right? That means more methane because  28  will be more burning of fossil fuels, ­ 29  more agriculture. Now you’re probably thinking, “Wait a minute, you said agriculture is going to be damaged by Global Warming, but  30  you’re saying agriculture is going to help cause Global Warming?” Well, have you  31 been in a barn filled with animals and you smell something  32 ? You re  33  methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem  34  the increasing population is  35 . More people means more cars, and more cares means more pollution. Also, many people have more than one car.

Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2.  36 , the trees that change our CO2 to oxygen are being demolished because we’re using the land that we cut the trees down from as property  37 our homes and buildings. We are not replacing the trees(an important part of our ecosystem), so we are  38  taking  39  of our natural resources and giving nothing back in  40 .

More than 20 million kids in the United States live with one parent. Separation and divorce are the most common reasons for this. In other cases, the mom and dad may never have lived together, or one of them may have died.

Living with one parent instead of two can bring about a lot of emotions. These feelings can be pretty strong, and they can be confusing, too. You might feel terribly sad and angry because your parents divorced.

Single parents are often working parents because someone needs to earn money to buy food, clothing, and a place to live in. Having a job means your mom or dad is able to provide these things and more for you. People work for other reasons, too. A job can let a person use his or her special talents and skills. A job can be important because it helps people in the community.

But even though you might understand why your mom or dad has to work, sometimes it can be hard to accept. This can be especially true during the summer or school vacations. You’re home, they’re gone, and the days can seem really long.

It can be tough when you don’t have enough time with your dad or mom. When you live with one parent, that person really has to do the work of two people. Besides a job, your mom or dad is responsible for caring for the kids, the house, the yard, the car and the pets. So what can you do ?

One of the best ways is to hold a family meeting. Talk about everyone’s schedule for work, school, and activities. You can also talk about what jobs around the house need to be done every day. You might want to help your parent cook dinner sometimes. That can be both fun and helpful to your parent. Maybe you can also schedule a weekly game or a movie at night.

D．Kids can also talk about what jobs in their school can be done at a family meeting.

A．the kid in the company of friends does want help

B．the kid who plays with both parents does need their love

C．the kid lacks both parents’ love does feel lonely

A small town in southwest Britain is banning (禁止) plastic bags in an attempt to help the environment and cut waste－a step that environmentalists believe is a first for Europe.

    Shopkeepers in Modbury population 1,500, agreed to stop handing out disposable plastic bags to customers on Saturday. They said paper sacks and cloth carrier bags would be offered instead.

    Last month, San Francisco became the first U.S. city to ban plastic grocery bags. Internationally, laws to discourage the use of plastic bags have been passed in parts of South Africa and Ireland, where governments either tax shoppers who use them or fine companies that hand them out. Bangladesh already bans them, and so do at least 30 remote Alaskan villages.

    Modbury, about 225 miles southwest of London, has also declared a bag ammesty (宽限期), allowing local people to hand in plastic bags that have piled up at home. They will be sent for a recycling.

    The Modbury ban was the idea of Rebecca Hosking, who saw the effect of bags on marine life while working in the Pacific as a wildlife camerawoman. She said response in the town so far had been “really positive”.

    “Modbury is quite an old-fashioned town and a lot of people have wicker(柳条) baskets to go out shopping anyway, ”Hosking told Sky News Television.

The World Watch Institute, an environmental research agency, states that 100 billion plastic bags are thrown away each year in the United States alone. More than 500 billion are used yearly around the world.

1.The underlined word “disposable” in the passage probably means        .

A. acceptable   B. valuable   C. environmentally-friendly         D. long-lasting

2.It can be inferred from the passage that         .

A. most of the people in Modbury continue to use plastic bags

B. fewer and fewer plastic bags will be used in the world

C. San Francisco is the first city to ban plastic bags in the world

D. most countries in the world have passed laws to ban plastic bags

3.Which of the following would be the best title of the passage?

A. Environmental Protection              B. Big Cities Banning Plastic Bags

C. British Town Banning Plastic Bags       D. Effect of Plastic bags on Sea Animals

In England recently three foreign gentlemen came to a bus stop and waited. About five minutes later, the bus they wanted came along. They were just going to get on when suddenly there was a loud noise behind them. People rushed onto the bus and tried to push them out of the way. Someone shouted at them. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreigners seem all at sea and looked embarrassed. No one had told them about the British custom of lining up for a bus that the first person who arrives at the bus stop is the first person to get on the bus.
Learning the language of a country isn't enough. If you want to have a pleasant visit, find out as much as possible about the manners and customs of your host country. You will probably be surprised just how different they can be from your own. A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table. The left hand is supposed to be used for washing yourself. Also in India, you might see a man shaking his head at another to show that he doesn't agree. But in many parts of India a shake of the head means agreement. Nodding (点头) your head when you are given a drink in Bulgaria will most probably leave you thirsty.

A. were foreigners　　                 B. didn't have tickets
