A．six half eight B．thirty to C．half past two D．ten o’clock ten 【答案】C 【解析】句意：——现在几点了？——两点半。 考查时间表达法。英语时间表达方式：“基数词+o’clock”表示整点；用基数词按“小时+分钟”的顺序直接写出时间；如果分钟数少于30分钟，可用“分钟+past+小时”表示；如果分钟数多于30分钟，可用“（60-原分钟数）+to+（原小时数+1）”表示；如果表示半点，可用结构“half past+小时”。结合选项可知，选项C“两点半”符合。故选C。 2．Our school has a big library. There are ________ books in it. A．thousand B．thousand of C．thousands of D．five thousands 【答案】C 【解析】句意：我们学校有一个大图书馆。里面有成千上万的书。 考查大数的表达。当thousand与数词连用时，表示一个具体的数字，后面不加s；当thousand与of+复数名词连用时，表示一个多而不具体的数字，后面加s。 根据“There are…books in it.”可知，此处可以泛指成千上万的书，只有thousands of“成千上万”表述正确。故选C。 3．—What class are you in? —I’m in ________. A．class one B．one class C．Class One D．One Class 【答案】C 【解析】句意：——你在哪个班？  ——我在一班。 考查编号的表达法。结合语境可知，该句在介绍所在班级，表达编号时通常用“名词+数字”形式，且首字母需大写，“Class One”意为“一班”。故选C。 4．There are already over two ________ students at this school, and ________ of them still want to study at it. A．thousand; thousand B．thousands; thousands C．thousands; thousand D．thousand; thousands 【答案】D 【解析】句意：这所学校已经有两千多名学生，其中还有几千人想继续在这里学习。 考查大数的表达。thousand“千”，前面有具体数字时，不加s和of；若前面没有具体数字，与of连用时，要加s。第一空前有two修饰，应用thousand；第二空与of连用，应用thousands。故选D。 5．There are ________ of people singing together at the concert .
