參考答案及解析：

1. D。I don’t expect so. = I expect not. 能這樣使用的動(dòng)詞還有believe, think和 suppose；而在hope等動(dòng)詞后，否定形式只有 I hope not. 不能說(shuō) I don’t hope so. 故答案為D。

2. C。how to 要連在一起使用，故排除A。only加狀語(yǔ)提到主句前面時(shí)，主句中主語(yǔ)和謂語(yǔ)用部分倒裝。故答案C。

3. B。that引導(dǎo)的是主語(yǔ)從句，而 if 從句是that主語(yǔ)從句中的條件狀語(yǔ)。故答案為B。
