参考答案:
1.正确答案:A
答案解析:表述永恒的真理或客观规律用一般现在时,不管主句谓语用什么时态。而“地球绕着太阳转”是客观规律,所以选A.
2.正确答案:C
答案解析:reluctant“不愿的,勉强的”:“他非常不愿意去,但他别无选择”,所以,reluctant用于本句合适。Hesitant“踌躇的,犹豫的”;ready“准备好的”;willing“愿意的”。
3.正确答案:A
答案解析:以分数限定的名词做主语时,谓语的单复数应同该名词保持一致,而不管分数是单数还是复数。此句中property(财产)是不可数名词,故用单数形式的动词。
4.正确答案:C
答案解析:nothing…more than是习惯用语,意思为“什么也比不上…更…”。句子意思为:记住,什么也比不上读得太慢更伤害注意力的集中了。
5.正确答案:B
答案解析:本句是带有不定式短语作目的状语的简单句。句意为“许多人都投入了身体锻炼计划,以保持良好的健康”。make a commitment“投入,保证”符合题意。
