新概念英语第二册49？新概念英语第二册Lesson50课文详注 1.I went on an excursion recently, but my trip took me longer than I expected.最近我作了一次短途旅行,但这次旅行所花费的时间比我预计的要长。 (1)go on在这里的含义为“为(某一目的)而去”: I'll go on holiday next month. 我下个月去度假。那么，新概念英语第二册49？一起来了解一下吧。
1. d
根据课文的情景，只有d. The bed was blown off the roof, but the man was not hurt 最能概括整篇课文的中心内容，其他3个选择都不全面，因此应该选d.
2. a
根据课文第9-11行Glancing at the bits of wood and metal…he promptly went to sleep again 可以判断只有a. he went back to sleep soon afterwards 与课文描述的情况相符，其他3个选择都与课文的实际内容不符。
3. b
a. because , c. As, d. For 都能引导原因从句，但是只有b. Because of 后面可以跟名词，表示原因，所以只能选b 才符合语法。
4. a
本句是一般过去时疑问句，因为已经有助动词did 提问了，后面只有用动词原形才对。 b. carries, c. carried, d. carrying 都不是动词原形，所以都不对。只有a. carry 是动词原形，所以选a.
5. b
本句是针对修饰动词的状语(副词)提问的，a. good (好的) 和d. nice (好的，美好的)这两个选择都是形容词，不能修饰动词;c. goodly 是形容词，有“漂亮”的意思，也不能修饰动词，只有b. well(好) 是副词，能修饰动词，所以选b.
6. c
这是一个对地点提问的疑问句，需要选出正确的回答。
off与from的词性相同，off后接the roof表示“离开、脱离”屋顶，from是“从。。”的意思。文章中是想说明床从屋顶刮落，有脱离的意思，简单用“from”无法确切表达这一含义。

以上就是新概念英语第二册49的全部内容，1. off 在这里是是介词，表示“从附着面脱离”，off the roof 就是“从屋顶的附着面脱离”，sweep the bed off the roof 意思是“把（放在屋顶上的）床从屋顶上吹离”。2. 如果改为 off from the roof ，off 是副词，意思是“处于不接触的状态” ，介词 from 指“离开某处”。
