新概念英語第二冊49？新概念英語第二冊Lesson50課文詳注 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,但這次旅行所花費的時間比我預計的要長。 (1)go on在這里的含義為“為(某一目的)而去”: I'll go on holiday next month. 我下個月去度假。那么，新概念英語第二冊49？一起來了解一下吧。
1. d
根據課文的情景，只有d. The bed was blown off the roof, but the man was not hurt 最能概括整篇課文的中心內容，其他3個選擇都不全面，因此應該選d.
2. a
根據課文第9-11行Glancing at the bits of wood and metal…he promptly went to sleep again 可以判斷只有a. he went back to sleep soon afterwards 與課文描述的情況相符，其他3個選擇都與課文的實際內容不符。
3. b
a. because , c. As, d. For 都能引導原因從句，但是只有b. Because of 后面可以跟名詞，表示原因，所以只能選b 才符合語法。
4. a
本句是一般過去時疑問句，因為已經有助動詞did 提問了，后面只有用動詞原形才對。 b. carries, c. carried, d. carrying 都不是動詞原形，所以都不對。只有a. carry 是動詞原形，所以選a.
5. b
本句是針對修飾動詞的狀語(副詞)提問的，a. good (好的) 和d. nice (好的，美好的)這兩個選擇都是形容詞，不能修飾動詞;c. goodly 是形容詞，有“漂亮”的意思，也不能修飾動詞，只有b. well(好) 是副詞，能修飾動詞，所以選b.
6. c
這是一個對地點提問的疑問句，需要選出正確的回答。
off與from的詞性相同，off后接the roof表示“離開、脫離”屋頂，from是“從。”的意思。文章中是想說明床從屋頂刮落，有脫離的意思，簡單用“from”無法確切表達這一含義。

以上就是新概念英語第二冊49的全部內容，1. off 在這里是是介詞，表示“從附著面脫離”，off the roof 就是“從屋頂的附著面脫離”，sweep the bed off the roof 意思是“把（放在屋頂上的）床從屋頂上吹離”。2. 如果改為 off from the roof ，off 是副詞，意思是“處于不接觸的狀態” ，介詞 from 指“離開某處”。
