可是我不明白第一题为什么不选C、第3题为什么不选A，第五题为什么不选B，和第十四题为什么不选A。
如果解答好的加悬赏

Answer 1

第一题speak to注重说的对象。常常用于电话中,e.g.May I speak to Jim?
talk to就是交谈的意思。非要解释就是这个道理，就好比，球类前不加the，乐器前一定加the，用法就这样
第三题，选over，把……放在上面；put sth on一般用作把某件衣服穿上；分工不同

第五题的理由和第一题类似。专门的电话用语
This is Mary speaking；或者It is sb。
第十四题，首先，得肯定can’t是对的。我恐怕你不能……
其次，为什么couldn’t不对，两种情况，过去式，这里显然不需要过去式；
表示语气委婉，通常在请求时用could，比如说Could I have a look at your book ?
