Some recent reports on the death penalty have brought some interesting responses from

readers all over the country. Although I really don’t like to make fun of people who oppose the

death penalty because they are so sincere, I wish they would come up with some new arguments to

replace the worn-out ones.

For example, many said something like this : “Wouldn’t it be better to keep the killers alive so

psychiatrists(精神科医生)can study them in order to find out what makes them the way they are?”

It takes the average psychiatrist about five years to figure why a guy wants to stop for two drinks after work and won’t quit smoking. So how long do you think it will take him to determine why somebody with an IQ of 92 decided to murder the little old lady who lives next door? Besides, we have a huge number of killers in our prisons—more than enough to keep all the nation’s psychiatrists busy for the next 20 years.

Another standard is: “The purpose of the law should be to protect society, not to give cruel punishment, such as the death penalty.”

In that case ,we should tear down all the prisons and let all the criminals go because most people would consider a long period in prison to be cruel punishment--especially those who are locked up. Even 30 days in the Cook County Prison is no picnic.

And: “What gives society the right to take a life if an individual can’t?” The individuals who make up society give it that right. Societies perform many functions that individuals can’t. We can’t carry guns and shoot people, but we give that right to police.

Words can not explain the suffering the families of murder victim are left to live with. The families suffer a terrible loss, and they live with terrible memories. The knowledge that the killers are alive and will probably remain alive and cared for you by society is extremely painful. Probably, people who oppose the death penalty should try explaining to these people how cruel it is to kill someone.

72.What’s the writer’s attitude towards death penalty?

A.Death penalty is a must.

B.Death penalty doesn’t solve all the problems.

C.Death penalty should be practiced more carefully.

D.Death penalty should only be used on murderers.

73.How many arguments against death penalty are discussed in the passage?

A.Two  B.Three       C.Four  D.Five

74.What does the last sentence of the text suggest?

A.It’s cruel to use death penalty to kill someone.

B.Murder victims need more comfort from the society.

C.Opponents of death penalty should offer explanations.

D.Murderers should be put to death as the punishment.

75.The author develops the passage by         .

A.providing typical examples of death penalty

B.following the natural time order

C.presenting and analyzing ideas

D.comparing opinions from different fields
