一、单项填空
1.People are living in______world where mouse clicks rule our life,so online searches have become______must.
A.the;/ B./;a
C.a;a D.a;the
解析:考查冠词的用法。句意:我们正生活在一个点击鼠标支配我们生活的世界里,因此网上搜索已成了一件(生活中)必不可少的事情。in a world...表示“一个……的世界”;a must表示“绝对必要的事情”,故两个空都用不定冠词。
答案:C
2.I have no one ______ me,for I am a newcomer here.
A.help B.helping
C.to help D.to have helped
解析:本题主要考查非谓语动词的用法。根据句意可知句子空白处的非谓语动词作定语,用have sb./sth.to do的结构。
答案:C
3.—I’m thinking of losing weight these days.
—Oh,you ______ be out of your mind.You’re 50 kilograms at the most!
