3. I don't want to buy the sweater because I don't like the color . (C), it is too expensive.
A Except B Except for C However D Besides
4.We Chinese people should (B) that China is just like a dragon proud and powerful.
A prove B make C test D present
5.An A4 sized panel (太阳能板） put onto the back of a jacket costs (B) US 15 dollars. It could ( ) a cellphone during a summer walk.
A at most ;work B at least ;control C at least ;fuel D at most ;charge
6.Mary 's pronunciation is much better than (D) in her class .
A anyone's B anyone 's else C anyone else 's D anyone else.
7.He asked , what is the matter ?变成间接引语——He asked me (D) with me.
A what the matter is B what the matter was C what 's the matter D what was the matter
8.The book cost me 12 yuan in all ,postage (A)
A included B including C includes D is included

3.except一般不用于句首,一般是将except for 置于句首.而且,except 后跟随的名词与前面所提到的名词属于同一类事物或同种概念,而except for后的名词与前面提到的名词则不属于同种事物或概念.试比较：The bus runs every day except Sunday.(day 和 Sunday）
This essay is good except for some spelling mistakes.（essay 和 mistakes）
besides和except的区别是besides ：“除…外,还有…”,指更进一步的拥有,包括所“除”事物在内；except：则不包括所除的事物.
以你这个句子为例,我不想买这件毛衣,不仅仅因为它的颜色不好看,（除了颜色不好看以外）还因为它的价格昂贵.因此,这里用besides是最为贴切的.
however,“然而”；“无论如何”,有转折之意.
4.答案应该是选A吧.A.证明 B.使；制造 C.测试 D.呈现
我认为句子应该是要表达说“我们作为中国人,应该证明中国就像一条巨龙,自豪而强有力的”.个人觉得这句话有问题,关键是“proud and powerful是修饰Chinese people 还是dragon.
5.这题选D更合理.at most 至多；at least 至少.charge 充电；control 管理,控制.
一块装在夹克背后的,A4纸大小的太阳能电池板至多花费人们15美元,人们在夏季的一次行走中,它可以为人们的手机充电.
6.答案是不是选C? anyone else 's在这里其实等于anyone else 's pronunciation,与前面Mary 's pronunciation是对应的,而且than为连词,连词前后的成分是一致的.
7.先看这个句子：Something is wrong with my computer.转为疑问句：What is wrong with
my computer?这里,what替换了something,成为了句子的主语,那么,在转化为宾语从句时就可说：Could you tell me what is wrong with my computer?而不会说Could you tell me what
wrong is with my computer?因为在这类句子中,what 就代表了一件事物,有类似于something的用法,能够直接充当宾从的主语.
不知道这样解释能不能让你明白,好好体会一下吧.
8.注意in all后面是逗号而非句号,“The book cost me 12 yuan in all ”已是个完整的句子,那么postage （）就相当于句子的一个附加成分.想表达“邮资已包括在内”的话,include就不能作为谓语动词出现,要考虑使用非谓语动词,而且是有被动含义在内,那么就只能选用过去分词形式.其实“postage included”是一个独立主格成分.
