　　Those against the use of animal testing claim that it is inhumane to use animal in experiments. I disagree completely due to the fact that compared with the use of animal testing, It would be much more inhumane to test new drugs on children or adults. Even if it were possible，it would also take much longer to see potential effects， because of the length of time we live compared to laboratory animals such as rats or rabbits.

　　Opponents of animal testing also claim that the results are not applicable to humans. This may be partly true. Some drugs have had to be withdrawn， despite testing. However， we simply do not have alternative methods of testing. Computer models are not advanced enough， and testing on plants is much less applicable to humans than tests on animals such as monkeys. We must use animal testing until we have a better system.

　　A further point often raised against animal testing is that it is cruel. Some of the tests certainly seem painful， but the great majority of people on this planet eat meat or wear leather without any guilt. Where is their sympathy for animals?Furthermore， animals clearly do not feel the same way as humans， and scientists are careful to minimize stress in the animals， since this would damage their research.

　　我们可以看出，在文章的每个主体段落中，作者都是先讲了反对者的一个观点，然后再反驳。

　　每个段落的段首的句型“Those against... claim that...”;“Opponents of ... also claim that...”;“A further point often raised against ... is that...”。使用了不同单词组合，但是意思是一致的，建议大家可以模仿这种写法。另外提醒大家最好将最重要的观点放在第一个主体段里面进行论述。

　　以上就是小编为大家带来的全部内容了，希望能给大家备考带来帮助。
