Answer 1

1.It turns out that seemingly ordinary old man is ____a prestigious scientist in genetics .
A.nothing but B.anying but C.no less than D.nothing more than
(题干是不是语意前后矛盾?)
没有矛盾啊，意思是：才发现那个看起来平庸的老人居然是一个受人尊敬的遗传学家。
选C

2.It is as a well-known scholar that he represents himself ,and____he is warmly received.
A.as much B.such as C.as that D.so that
(题干中，as...that 是什么句式？）
as和that不组成句式、it is 和that一起组成强调句。
选D

3.Which of the following is the correct response to "Susie had a wonderful time at the party"?
A.So she had, and so did I B.So had she ,and so did I
C.So she did, and so did I D.So did she, and so did I
(had 与did 的区别？）
so she did的意思是“是的，她是玩的很开心。”
so did I 是“我也是”的意思，倒装句，原句是i did so （too）
had和did是根本就不同的2个词，没什么好比较的。
这题考的是用助动词表示过去式
选C

4.She tried dozens of companies only to be told no_____available right now.
A.position B.post C.professiong D.occupation
(position 与 post 的区别？)
也是2个不同的词 2个词没关系。
选A

5.I don"t think he____there as no one seems to have seen him.
A.could have been B.can be C.should be D.might have been
(could与might 区别？)
前面I don"t think 已经肯地表示不认为了，因此没有might这种可能了，再看as后面引导的原因状语从句，as no one seems to have seen him，“因为好像没人见过他”，由此判断前面用A

6.She changed a lot from the years of suffering.She is not the pretty girl_____she was ten years ago .
A.that B.who C.what D.whom
（此题考点在哪？）
这题考定语从句。
用who，选B

7.Only take those things ___really necessary when you go out for a climbing.
A.as are B.as were C.as they are D.as they were
(此题中as引导什么句型，这里as是什么用法？)
take……as，把某物当作什么样的，句意去登山的话就把那些东西看做重要东西。
选C

8.The language ____ and culture differences are big problems once people want to study abroad.
A.barricade B.obstacle C.barrier D.obstruction
A是路障，B“阻碍前进的东西或状况”，C是障碍, 防碍因素; 障碍物，D是指“阻碍整个通道的阻塞物”
我觉得选C或者B

9.He ____out of the office without being noticed by the boss .
A.slipped B.lurked C.sneaked D.crept
选C，偷偷溜掉，老板都没看见

Answer 2

我的英语还可以
我觉得学好英语最重要的是记老师写的笔记,那是最重要的,老师写的一定是重要的,不要偷懒.
语法我个人觉得重要的是:宾语从句,被动语态,时间状语从句,让步状语从句.
就看你学的是什么版的英语了,不同就会有不同的知识.单词主要的是会写,会写了作文就不会丢分了,如果你不会读就学音标,学会音标就会拼读了,但是现在不要求学音标,现在不考可是要学也是可以的,要想学好语法就要去买关于语法的说来看,语法是很重要的,语法学不好就很难学好英语了.我不是专家,我只能说这些了,你要加油哦
