　　答案：

　　1.^they-that．分句后的分句应有它独立的主谓结构，正像它前面的结构一样。而后半句的谓语是is，表语是fact，主语似乎是缺失的，因此在they前面加上that就构成了主语从句作为这半句的主语。

　　2.stimuli-stimulus．stimuli看似单数实则是stimulus的复数形式，因此应改为stimulus。

　　3.to-/．这里的need作情态动词，因此删去to。考试大

　　4.or-nor．并列的否定，用否定形式nor表示倒装。

　　5.on-in．in profile表示 “侧面，从侧面”。如：The painting shows her in profile。

　　6.^opposed-as．opposed前应使用连词as引导比较分句。

　　7.old-olds．由谓语的复数形式可以看出这里需要用复数形式four-year-olds。

　　8.and-but

　　9.furthermore-however．上一句话指明美国文化中眼睛的重要性，而这一句话似乎指出日本文化中眼睛并不具有同样的重要性，因此两句话的关系是转折而不是递进。

　　10.like-as．句子中有一个as……as比较结构。
