Accidents happen almost daily. Some accidents are minor and some are serious but others may be fatal. We read about such accidents nearly every day in the newspapers. It is wrong for people to think that accidents occur only on the roads or highways, or even at worksites. Home accidents are just as common. Because very few home accidents are reported, people tend to think that there are few accidents which happen in homes.

There have been many cases where people fall to their deaths from high-rise flats. Children often fall from staircases while coming down the stairs. Old people may slip on wet or slippery floors if they are not careful.

Nowadays there are a lot of modern electrical appliances such as rice-cookers, electric irons, and kettles which make life easy for the modern housewives. These appliances can kill if they are not used in the proper way.

Gas stoves used for cooking are also dangerous if they are not properly handled. They may cause burns or, in more serious cases, they may even cause fires.

But all such accidents can be prevented if we are careful and obey simple rules of safety. For example, it is unwise for people to try repairing their own electrical appliances if they do not know how. It is safer for them to get their faulty appliances repaired by a qualified electrician.

A. there are more road accidents

B. many home accidents are not reported in newspapers

D. such accidents happen nearly every day

Which of the following is TRUE about the modern electrical appliances?

A. They help modern housewives a lot.

B. They are very dangerous and should not be used.

C. They are usually safe unless they are used carefully.

D. They are not dangerous even if they are used carelessly.

There was a time when，if a lady got into a crowded bus or train，a gentleman would immediately stand up and offer his seat.But now，things are different.Today a gentleman will probably look out of the window or if he feels a bit shy，hide behind his newspaper.Either way，the lady will have to stand until someone else gets off.

You can’t entirely blame men for this change in manners，though.Gone are the days when women could be referred to as weakers without causing trouble.A whole generation of women has grown up demanding equality with men，not just equality in jobs or education，but in social life.Hold a door open for some women and you are likely to get an angry lecture on treating women as weakers unable to open doors for themselves.Take a girl out for meal and she’ll probably insist on paying her share of the bill.On second thoughts，that is perhaps not a bad idea.

It’s no wonder，then that men have given up some ways of politeness and consideration which they used to show towards women.On the other hand，the man’s active politeness is perhaps slowly being replaced by true consideration for the needs and feelings of women，so that men can see women as equal human beings，rather than as weakers or something that can be used to please men.

Maybe it is worth women’s while to stand in the bus or train.

46．Which of the following is true according to the passage?

C．she feels herself treated as a weaker

D．she thinks it impolite for a man to do so

48．If a man takes a girl out for a meal，she insists on paying her share of the bill.That means________.

Many children first learn the value of money by receiving an allowance. Parents often give their children an amount of money that they may spend as they wish. The purpose is to let the children learn from experience at an early age when financial mistakes are not very costly.

A child may receive an allowance each week or each month. The amount is not so important. But parents should make clear what the child is expected to pay for with the money.

At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents should not offer more money until the next allowance is to be given.

Older children may be responsible enough to budget larger costs like those for clothing. The object is to show young people that a budget demands choices between spending and saving.

Many people who have written on the subject say it is not a good idea to pay your child for work around the home. These jobs are a normal part of family life. Paying children to do extra work around the home, however, can be useful. It can even provide an understanding of how a business works.

Allowances give children a chance to experience three things they can do with money. They can share it in the form of gifts or giving it to organizations. They can spend it by buying things they want. Or they can save it.

Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer free savings accounts for young people with small amounts of money.

1.The functions of allowances given to children are the following EXCEPT ______.

A. they can save more money for their future business

B. they can give them to charities

C. they may spend them on what they like

D. they can learn to deal with money

A. 牺牲 B. 计划 C. 选择 D. 放弃

3.What's the main idea of the passage?

A. Children should save part of their allowance.

B. Don’t pay your child for work around the home.

C. Allowance helps teach children early about money.

D. Parents should allow children to spend money as they wish.

4.How many advantages of saving has the passage mentioned?

A. 2 B. 3 C. 4 D. 5

5.Which of the following is TRUE according to the passage?

A. Children are advised to buy anything they wish to with the allowance.

B. Parents should offer children more money if they spend all of their allowance soon after they get it.

C. It can be useful to pay children to do extra work around the home.

D. It is unnecessary for the children to save part of the allowance.

Unlike Britain, the US does not have a national health care service. Most people buy medical insurance to help pay for medical care. The government only helps pay for some medical care for the old and the people who are on low incomes. The problems of those who cannot afford insurance have become an important political subject.

In Britain, when people are ill, they usually go to a family doctor first. However, people in America sometimes go straight to an expert. Children are usually taken to a doctor who is an expert in the treatment of children. In Britain, if a patient needs to see a specialist doctor, their family doctor will usually recommend a specialist, which will save more time and money both for the patients and the public fund（基金）.

In Britain, doctors do not go to people’s homes when they are ill. People always make appointments to see the doctor in the doctor’s office. In a serious situation, people call for an ambulance. In America, hospitals must treat all seriously ill patients, even if they do not have medical insurance. The gov-ernment will then help pay for some of the cost of the medical care.
