例 1
The first necessity of child upbringing is a
secure emotional background with parents who
are united in their attitude with children. 1.__________
“ attitude toward ” 是表示 “ 对 …… 的态度 ” ，为固定用法，而没有 “ attitude with ” 的用法，因此应该将 with 改为 toward.
例 2
Unfortunately we have not found complete
solutions with the various problems of our 1.__________
society, such like poverty, homelessness or 2.__________
the growth of crime.
“ solution to problem ” 表示 “ 问题的解决办法 ” ，为固定搭配用法，因此应该将 with 改为介词 to ， “ such as ” 表示 “ 例如、诸如 ” 的意思，为固定搭配，因此应该将 like 改为 as 。
例 3
More and more people live in towns and cities
instead on farms and in villages. 1.__________
Instead 本身为副词，其后不可以直接接宾语，而应该在后面加上介词 of 。“ instead of ”表示“代替，不是……”的意思。
例 4
His Arab host, who had been watching, said
of nothing, but immediately copied the action of 1.__________
his guest.
动词 say 本身即为及物动词，后面可以直接接上宾语，因此不需要在后面加上介词 of 。这属于介词滥用情形，应该将 nothing 之前的 of 删去。
通过上述几个例子可以看出，介词的用法灵活多变，且许多为固定的用法或者搭配形式。要想真正克服这个拦路虎，我们需要在平时的学习过程中加以记忆和理解，逐步积累，才可以更好的掌握其用法。

答案解析：
1.将like改为as。
2.将for改为on或者upon。和前面的名词effect搭配的介词为on或者upon，意为“对……的影响，对……的作用”。类似的词组还有impact on/upon（对……的影响或冲击），influence on/upon（对……有影响）等。
3.在much之前加上介词as。
4.将with改为from。
5.将with改为at。当表示速度的时候应该使用“at the speed of”或者“at…speed”，“with…speed”没有这个用法。
6.将as改为like。此处的“to him”仅为一个插入语，原句的顺序可以理解为“that looked very much like a napkin to him”。
7.将in改为on。“on the decline”表示“下降，减少”的意思，为固定搭配用法。
8.删去of。此处comprise虽然与consist，compose意义相同，但是使用方法却不一样。Comprise为及物动词，后面不需要接介词，consist后面要加介词of，而compose一般使用be composed of的形式。
9.在referring后面加上介词to。
10.在arriving后面加上at。
11.将by改为for。“be known for”表示“因为……而出名，以……闻名”之意。而“be known by”是指“被……知道”的意思。
