参考答案：
1. 答案是D. 同级比较的结构为 as+ 副词原形+ as.
2. 答案是C. almost 意为 几乎、差不多，at most 意为 至多， 均与语意不合。most 意为多数的，mostly是副词，意为主要地、大部分地。
3. 答案是C. 答题的关键是要知道grain 为不可数名词。
4. 答案是D. 本题考查对基本句型的掌握。从表面上看，4个选项似乎都可以修饰形容词，而且从上下文中也很难找到提示。其实，命题者有意将题中to carry省略。如果能判断出其省略部分，便很容易想到toofor sb. to do 这个句型。
5. 答案是D。通过信息句He left about three weeks ago. 可判断出空白处强调的是时间
不再。 no longer 常在句中强调时间，而no more 常强调数量和次数。
6. 答案是C. 表示倍数的词或其他程度副词作修饰语应放在asas结构的前面。
7. 答案是D. no more与no longer 变为 not any more 或notany longer时，any more或any longer 要放在谓语动词后。
