1.with his attention ( ) on the job ,he did noteven look up when we came in A focused B focusing C to focus D having focused为什么选A 不选B 2.The lady ( ) thirty poor students go to college by the end of last year.A helped B had helped C has he
1.with his attention ( ) on the job ,he did noteven look up when we came in
A focused B focusing C to focus D having focused
“注意”是被集中到工作上,所以要用过去时
2.The lady ( ) thirty poor students go to college by the end of last year.
A helped B had helped C has helped Dwould have helped
帮助这个动作在一个过去的时间 the end of last year已经发生完了,所以是过去完成而不是现在完成
3.( )all of the questions have been settled ,you can go on with your work
A only if (除非..才) B even though (即使) C now that (既然,由于) D what if(倘使...将会怎样;即使...又有什么要紧)
选C翻译成“既然你的问题已经解决了,你可以继续工作了”,选A的话CAN要改为could,因为only if 引导了条件状语从句后面要用虚拟语气.

focus one's attention on 所以with attention focused on (被动）
by the end of +过去时间 和过去完成时连用
+将来时间 和将来完成时连用
A 主句需要倒装

1. 考查“with+名词/代词+动词ing分词/动词ed分词/to do”，解题思路就是理解题干意思，若表目的、将来，则用to do形式；若不是，则考察该结构中动词与with后的名词或代词的关系，若为主动关系，则用动词ing分词；但若为动宾关系（即被动关系）则用动词ed分词。联系“把某人的注意力集中于某事”的英语表达“focus one's attention on sth” 可知，此处应用fo...

1. 考查“with+名词/代词+动词ing分词/动词ed分词/to do”，解题思路就是理解题干意思，若表目的、将来，则用to do形式；若不是，则考察该结构中动词与with后的名词或代词的关系，若为主动关系，则用动词ing分词；但若为动宾关系（即被动关系）则用动词ed分词。联系“把某人的注意力集中于某事”的英语表达“focus one's attention on sth” 可知，此处应用focused.
2. 选项B与C的区别在于参照的时间点不一样，现在完成时是参照现在而言的；而过去完成时则是参照过去某个时间；故此题关键在于发现时间的参照点。从题干中的时间状语by the end of last year（到去年结束时）可知参照的时间点是过去，故用过去完成时，而不用现在完成时。
3. only if 意为：“只有”。Only 修饰状语位于句首时，主句需部分倒装。若选A，其后的句序应改为can you go on with your work. 如：On in this way, can we study English well. 故不能选A，而选C。
