1. _______ the whole, early American city planning was excellent.
A. In B. From
C. On D. Above
答案：C【句意】总的来说，美国早期的城市规划是不错的。
【解析】on the whole是固定搭配，意为"从整体来看，大体上"，如： On the whole，the performance was a success. 从整体来看，演出是成功的。
2. _______ we are having these days!
A. What a lovely weather B. What lovely weathers
C. What lovely weather D. What lovely a weather
答案：C【句意】这些天的天气是多好啊。
【解析】weather是不可数名词，所以 A可以排除。how引导感叹句时后面一般用形容词或副词，而what引导感叹句时应一般用名词(包括不可数名词)，据此D也可以排除。weather为复数时一般指"处境，境遇"，故B也不合适。由此可见只有C是正确答案。(可参见薄冰的《英语语法》P.496上的例句：What delightful weather we are having!这天气多好呀!)
3. _______ we have finished the course, we shall start doing more revision work.
A. For now B. Now that
C. Ever since D. By now
答案：B【句意】既然我们上完了课程，我们就要开始做更多的修改工作。
【解析】根据句子结构我们可以看出，这里需要一个关联词来引导出一个状语从句。 since或now that或now可以用来引导原因状语从句，从句内容是一个既定的事实，例如： Now that you will come here，I needn't go there.既然你要来，我就没必要到那儿去了。ever since后既可跟名词也可跟从句，表示"自从……以来".如用在此处，则不合乎逻辑，例如：He has not written any letters to her ever since he was ill.自从他生病以来，他从未给她写过信。 by now只能作状语， 不能引导从句，意为"到目前为止"，例如： She ought to have arrived at her office by now.她现在本该到办公室了.虽然for可以引导表示原因的分句，但该分句要位于第一个分句之后，例如： I don't like him，for he always makes empty promises.我不喜欢他，因为他总是作一些空头许诺.
4. ______ when she started complaining.
A. Not until he arrived B. Hardly had he arrived
C. No sooner had he arrived D. Scarcely did he arrive
答案：B【句意】她以来就开始抱怨。
【解析】句型"hardly(scarcely)…when"和"no sooner…than"表示"一……就"，例如：No sooner had he arrived home than he was asked to start on another journey.他刚到家就被要求做另旅行。Hardly had she agreed to marry him when she began to have serious doubts.她刚同意同他结婚，就开始产生严重的疑虑。Scarcely had he entered the room when the phone rang.他一进房间电话就响了。因此，B正确而C错误。由于主句谓语动词arrive要先于从句谓语动词start，因此从句使用一般过去时时，主句只能使用过去完成时，所以，D错误。 not until或"not…until"意为"直到……才"，用来引导时间状语从句，例如： Not until midnight did they find their lost child.直到深夜他们才找到走失的孩子。根据句子结构，not until he arrived若用在这里，整个句子就没有主句了，犯了结构不完整的错误，因此，A也不是正确答案。
5. _______ whether he will come or not.
A. There is no telling B. There is not telling
C. There is telling not D. There is not to tell
答案：A【句意】他不可能来。
【解析】"There is no doing sth.…"或"There is not any doing sth.…"相当于 "It is impossible to do sth.…"，意为"做……是不可能的"，如：There is no knowing when he would be back.无法知道他什么时候回来.又如：There is not any telling what became of her.她出什么事了，无可奉告。
