问题     One of the many questions brought up is in regards
with whether or not cloning should be an option for 【M1】______
parents that are considering having children. Many
problems often occur with couples involve the issue of 【M2】______
infertility. Some people believe that cloning should
aim its main focus to help infertile couples — and they 【M3】______
will likely conclude that there is nothing wrong with it.
The scarcely hidden assumption is that anything which 【M4】______
helps overcome infertility is morally appropriate. As 【M5】______
in vitro fertilization so popular in today’s society
among infertile couples, who is to say that in the
future, cloning won’t take over? Cloning is noticed to 【M6】______
be better for treating infertility in a sense that it can 【M7】______
eliminate health problems with the child from the
beginning. This proves to be beneficial in the way that
a couple is more than likely guaranteed a healthful 【M8】______
child. Cloning does not, however, always prove to be
beneficial. For example, in the case when a certain 【M9】______
disease is on the rise and one of the three clones gets it,
the immune system of other two clones is identical 【M10】______
which proves that they have no guard against diseases. [br] 【M2】
选项
答案 involve—involving
解析 非谓语动词错误。英语中每个独立的句子只能有一个谓语动词，而本句中出现了occur和involve两个。根据句意判断，本句的重点在“问题的出现”，因此应保留occur作为谓语动词，而将involve改为现在分词形式involving，作主语补足语修饰problems。
