几道初三英语单选题，烦请解释一下原因！~

非常感谢帮助，题目如下：(格式最好是：句意+原因/语法点）

A.to that B.to them C.with that D.with those
帮分析一下A哪错！

2、Only _____ as an interpreter______ how important it is to grasp English
不打选项了，问：when I worked;did I realize 为何对?

3、It was the training ____ he had as a young man ____ made him such a engineer.
A.what;what B.which;that C.that;which D.that;what

4、it was 和 was it 有何区别？

以上题做题的技巧是神马？Thanks!!!

Answer 1

1. costs 为复数 ，但是that 只能代表单数，故要用those 了。
2. only 位于句首需要倒装的这个单选题应该是用排除法做出来的，前面woked 已经用了过去式，所以后面要说did 而不是 had ,is 之类的。另外后面的realize 就必须用一般现在时了，因为前面已经用过一次did 了。
3、这个显然是一个it ,,that 强调句型 ，这种句子一般最后一个空都是that ，所以直接就有答案了，前面一空用which ，不填也可以。it that 用法如下
1. I am right. 我是对的。

It is I that/who am right. 正确的是我。

2. We met a foreigner at the school gate. 我们在校门口遇见一位老外。

It was a foreigner that/whom we met at the school gate.

我们在校门口遇见的是一位老外。

3. Tom lost his wallet in the supermarket. 汤姆在超市里丢了钱包。

It was in the supermarket that Tom lost his wallet. 汤姆是在超市里丢的钱包。

4. She didn’t go to work because her mother was ill. 因为妈妈病了，她没去上班。

It was because her mother was ill that she didn’t go to work.

她没去上班是因为妈妈病了。

5. The Second World War broke out in 1939. 二战爆发于1939年。
背诵下面的对你以后很有用处。
比较 a. It was at midnight that I got back home yesterday.

It was midnight when I got back home yesterday.

b. It was two years ago that I began to learn French.

It is/has been two years since I began to learn French.

c. It was two years later that he came back from abroad.

It was two years before he came back from abroad.

d. It is in two years that he will graduate from college.

It will be two years before he graduates from college.

e. It was in a mountain village that we met for the first time.

It was a mountain village where we wet for the first time.

4.这个实在不好说，一个用到陈述句，一个用到疑问句，不知道你想要问什么，你这个问题就好像是在说是的和是吗什么区别。

It was in 1939 that the Second World War broke out. 二战是在1939年爆发的。

6. He didn’t go to bed until ten o’clock.他

It was not until ten o’clock that he went to bed.

呃，我主要想问这俩词后面+that有何区别，很感谢你能复制例句（但最后两句有问题吧！中文。。）

追答

不好意思，我给你翻译一下，他直到十点才睡觉，你把这几个句子背会，以后出道这些题你就不会错了，其实英语很多时候是你先要背会然后再去理解，就想吃东西，你要先吃下去，然后才可以去评价回味，不能什么也不吃就拿着筷子对着这东西说好吃不好吃，实践出真知，语言学习是需要先囫囵吞枣的。

追问

恩，说的极是，您很有经验，再问一下：which 和 that 在做选择题时该如何辨别或这俩词有何本质上的差异；介词可以位于句尾么（如：paid for..)？很感谢！！！

追答

这涉及到定语从句了，　我记得初中时候是还没有学这个的　，你可以自己去看看，介词是可以放于句尾的，而且还有很多用法，举一个简单的例子，where are you from?这里就是介词位于句尾。

Answer 2

1、compare sth. with sth 把前者和后者作比较。而compare .. to 是把“什么” 比作 “什么”是意思
2、only置于句首，从句用陈述语序，主句用倒装；
3、强调句 it is 强调部分 + that + 其他。排除A、C
4、一个是陈述语序，另一个是倒装

Answer 3

compare A to B 的意思是把A比作B啊！根据句意应该是比较而不是比作。所以不能用A。
only+介词、副词、从句位于句首时句子要部分倒装，也就是把be/助动词/情态动词提到主语前。
3.前面是定语从句，先行词是training,在从句中做had的宾语，而后面是一个强调句，构成为it was......that.意为：正是他年轻时受过的培训使他成为了这样一名工程师。
4.一个是陈述语序一个是疑问语序啊。
技巧：先看答案，通过答案了解此题的考查点，然后在对症下药。

Answer 4

1，"A compare to B" 是“把……比作”；"A compare with B"是“把A与B作对比”
2，"when I worked"时间状语从句，用陈述句语序，
后面“as an interpreter did I realize ”才是"only"强调的部分，
only强调的部分"I realise"要加"do”的适当形式
3，It was the traning 主+谓+宾
he had as a young man主+谓+状t that为从句的宾语
made him such a good engineer. 谓+直接宾+间接宾 that做从句的主语

整个句子有两层 是一个主语从句套定语从句
第一层It was the traning that It was the traning that he had as a young man that made him such a good engineer..主语从句 由于主语太长或者需要强调就用it+is+n. +that形式主语的结构
正常语序为what made him such a good engineer is the traning
是一个主语从句 that的先行词是It
第二层the traning that he had as a young man定语从句 that先行the traning 并作从句的宾语
可以看作the traning that he had（it） as a young man (it=the traning)

整个句子可以另一个写法
what made him such a good engineer is the traning that he had as a young man
如果这样看就比较好看出来 ，第二个that在主句中是必要成分作主语不能少， 第一个that只是修饰成分作定语，虽然表达可能不清楚，但是没有语病

追问

第3问的主语从句是高中英语的吧，能再简化一下为初中英语么，不好意思（你虽然分析的很好！）

Answer 5

1、（1）compare... with...将。。。与。。。比较；
compare...to...将。。。比作。。。
（2）如果你将一年前食品价格与今天的食品价格比较，你会发现不同之处；
选D。用those指代“food costs "
2、为何对？？就是对的，“Only”引导的主句要倒装啊。
3、选B。真是他受过的作为年轻人的训练使他成为工程师。
It was ... that...强调句； he had as a young man 是 training 的定语从句用which或that都行。

4、前者是陈述句，后者是问句。

技巧是把语法掌握通了就行了，语言没有捷径的，一点点积累就好。加油哦！！

追问

我对于第2问的解答不是很能理解，不好意思，那如果说。。（停一下）请看下下面这道题：
On the bed ______
是a poor old sir lay 还是a poor old sir did lie 对

Answer 6

1.compare to 有比作的意思
2.only开头其主句要变为疑问句式的倒装句
3.b，which作宾语，that强调句
4.前者陈述，后者疑问
