sth.”去做某事是……的。句中缺少不定式,故选A。59.B【解析】句意:我花了很多时间为十个人准备了一顿大餐。考查非谓语动词。本句是固定句型“It takes sb. + 一段时间 + to do sth.”表示“做某事花了某人多长时间”,其中动词不定式“to prepare”作真正的主语,it为形式主语。故选B。60.D【解析】句意:周末待在家里真无聊。考查动词不定式。“It’s+ adj. + to do sth. ”是固定句式,意为“做某事是……的”,It为形式主语,真正的主语是后置的动词不定式。故选D。61.A【解析】句意:对我来说,最重要的是要高兴。考查介词和非谓语动词。It’s+adj.+for sb. to do sth.对某人来说,做某事是……,it是形式主语,to do sth是真正主语,故选A。62.D【解析】句意:在工作日,学生在学校穿校服是必要的。考查非谓语动词及近义词辨析。dress穿衣,其后不加衣服,dress sb. in给……穿衣服,dress in穿……的服装,强调服装的样式;put on穿上,强调动作;wear穿着,强调状态;It’ s +形容词+for sb. to do sth.对某人来说,做某事是……,固定句式。空后有school uniforms校服,所以此处使用wear。故选D。63.D【解析】句意:——了解一些外国风俗对我们有帮助吗?——是的,有用。我们在出国旅行之前应该注意这些问题。考查it固定句型。根据“Is it helpful...us...about some foreign customs ”可知,此处指了解一些外国风俗对我们有帮助,形容词helpful与事物的特征有关,应用句式“It is+形容词+for sb.+to do sth.”,意为“对某人来说做某事怎么样”,第二空应填不定式to learn。故选D。64.B【解析】句意:——人们可以在互联网上找到大量有用的信息。 ——是的。学会使用电脑是很重要的。考查形容词短语和动词不定式作真正主语。a large amount of“大量的”,后接不可数名词;a large number of“许多”,后接可数名词的复数形式。第一空,根据空后不可数名词“information”可知,此处应用a large amount of,排除C和D;第二空,分析句子结构可知,此处考查It’s adj. to do sth.“做某事……”,其中it为形式主语,动词不定式为真正的主语,排除A。故选B。65.C【解析】句意:对我们来说,多吃蔬菜是健康的。考查it的固定句型。固定结构“it’s+adj.+for/of sb.+to do sth.”意为“做某事对某人来说是怎样的”,其中“it”是形式主语,真正的主语是后面的动词不定式,即“to eat more vegetables”,且形容词healthy在此表示事物的特征,即吃更多蔬菜是健康的,用介词for。故选C。66.B【解析】句意:在课堂上读英语是不够的。你应该在业余时间多读书。考查动词辨析及非谓语动词。say说;read阅读;speak说。根据“You should read more in your spare time”可知,此处指读英语。It’s +adj.+to do是固定句式,意为“做……怎么样”,其中的动词不定式作主语,it是形式主语。故选B。67.C【解析】句意:——夏天是游泳的最佳时间。——你说得对。但是不要一个人去游泳。考查非谓语动词。根据“It’s the best time”可知,此句是“It’s time to do sth.”句型,第一个空填to swim;又根据短语go swimming“游泳”可知,第二个空填swimming。故选C。68.C【解析】句意:俱乐部的目的是为了得到乐趣。考查不定式用法。have fun动词原形;having fun动名词形式;to have fun动词不定式;had fun过去式。句中空处作表语,用于说明俱乐部的目的是“为了……”,需要不定式短语来充当。故选C。69.B【解析】句意:工人的职责是保护那些动物。考查非谓语动词。protect动词原形;to protect动词不定式;protected过去式;will
