Unit 2 Grammar
基础篇
一、单项选择。
1.Because of the special situation this year, about ________ of the students in our school ________ having classes on the Internet at home.
A. two thirds; are B. two third; is C. second thirds; are D. two thirds; is
【答案】A
【解析】句意:因为今年的特殊情况,我们学校大约三分之二的学生在家上网课。
考查分数的表达以及主谓一致。分数是由基数词和序数词一起来表示的。基数词作分子,序数词作分母,除了分子是“1”以外,其他情况下序数词都要用复数形式。此处表示“三分之二”,分子用基数词two,分母用thirds。“分数+of+名词”作主语时,谓语动词常与of后的名词保持数的一致。of后the students是可数名词复数,则谓语动词用复数形式are。故选A。

C. Lesson Sixth D. The Lesson Sixth

It's reported that over 500 ______ tourists came here yesterday.

A.anything new; ten-year-old B.nothing new; ten-years-old
C.anything new; ten-years-old D.nothing new; ten-year-old
【答案】A.
【解析】考查不定代词.句意:-今天的报纸有新鲜的事情吗?-有.一群十岁的孩子参加了志愿者.something用在肯定句中,而anything用在疑问句或否定句中,本句是疑问句,用anything.不定代词的修饰语要后置;第二空是复合形容词修饰名词kids,ten-year-old十岁的.

A.In 1970's B.In 1970s C.In the 1970s' D.In the 1970s
