Fifty dollars will _ the hotel expenses.
A.cover B suit C.spend D.cost
这题不是说55元花在酒店到吗,应该选D的,答案为什么选A
【解析】cost,spend 的主语都不能是钱数.cover 在这里是“足够支付”的意思,主语经常是钱数,或者salary/earning等,例如：His earnings don't cover the family needs.他的收入不够支付家庭的需要.
21.John has a new car.I wonder when_ it.
A.he got B.did he get C he gets Dhe is gelling
为什么选A
when引导的是wonder 的宾语从句,从句的语序必须是陈述句语序.而他买车必然是发生在过去,因此用过去时态.
24 .However much _.it will be worth it
A.does the watch cost B costs the watch
C the watch will cost D.he watch costs
选A为什么错,答案是D
这道题还是考察从句的语序,however much.从句的语序一定是陈述句语序!因此必须选D,楼主少打了一个字母吧?D.the watch costs
26.He fell off his horse a week ago and_in bed ever since.
A was B had been C.would be D has been
为什么选D
ever since “从那之后.”,提醒你“之后他就一直卧床”,是现在完成时的时间状语
28 Before he set off I packed him some food___he wouldn't get hungry
A.because B lest C.even D.so that
为什么选D
so that 引导的是结果状语从句,翻译过来的意思是“以便.”,其他的逻辑都不正确
29 With such a variety of food for the dinner.I just didn't know which dish_
A.to begin with it B to begin C.to begin with D.to begin il for
为什么要用with
begin with 是词组,也可以说是“惯用语”,意思是“以.开始”,句子的意思是“我都不知道以那道菜开始这顿餐”.再举个例子,The teacher starts the class with explaining the new words.老师以讲解生词开始上课.
33.They arc going to_their house by building two more rooms onto it
A.enlarge B.increase C.develop D spread
spread不是扩大的意思么,为什么选D错
enlarge扩大体积,使什么东西变大(一般是具体的东西)
spread传播(一般是抽象的东西）比如“传播疾病、宗教”等等
44,_the right address.we found her house easily.
A.Given B.Having given C.Giving D.Give
为什么选A
given 也是固定用法,given+名词的意思是=if.（名词） is given,也就是说前半句话=If the right address is given
55 _today,he would get there by Friday.
A Was he leaving B Would he leave C Were he tu leave D If he leaves
答案是C Were he to leave.这是一道虚拟语气的题目,后半句he would get there by Friday,判断前半句必须用过去式,表示现在虚拟,
be to 是词组,意思是“准备,将要.”
这里是省略连词的倒装形式If he were to leave today= Were he to leave today,.
