新概念英語第二冊課后習題Lesson 27
    1. d
    根據(jù)課文第5-6行but some time later it began to rain. The boys felt tired so they put out the fire and crept into their tent…只有d. it had begun to rain and they felt tired 才是孩子們?nèi)ニX的原因。 a. it was late 是事實,但不是他們睡覺的直接原因;b. they had sung songs 不合乎邏輯; c. it began to rain 只是一方面原因,不夠完整。
    2. c
    根據(jù)課文后兩行The stream wound its way across the field and then flowed right under the tent! 只有c. The boys had camped in the path of a stream(孩子們在一條小溪穿夠的地方露營)與課文的實際情況相符。其他3個選擇都與課文實際不符。
    3. d
    a. it put up, 和 b. their tent put up 語序混亂,不合乎語法; b. put up it 也不對,當賓語是代詞時候,應(yīng)該將it 放在動詞和副詞之間; 只有d. put their tent up 合乎語法,語序也對,所以選d.
    4. d
    a. As soon 不能引導(dǎo)狀語從句,因為后面缺少as; b. Just as(正當)可以引導(dǎo)從句,但不太合乎題義,因為它強調(diào)兩件事情同時發(fā)生,而這個句子是表示兩件事情一前一后發(fā)生,c. Until(直到……為止,在……以前)詞義不對,只有d. Just after(剛剛……之后)合乎題目意思。
    5. d
    a. they had hunger 不符合英語習慣用法;b. they had hungry 不合乎語法,hungry 是形容詞,它前面應(yīng)該是系動詞be,而不是had; c. they were hunger 不合乎語法,系動詞were 后面應(yīng)該跟形容詞hungry; 只有d. they felt hungry 符合語法,因此選d.
    6. b
    只有選b. near 才能同前一句中的by the campfire(在篝火旁)意思相同。 a. close 不能做介詞,可以是close to the campfire; c. besides 是介詞,表示“除……外”,詞意思不對;d. at (在……上)也不合乎題目意思。
    7. a
    本句是一般過去時的疑問句,需要選正確的謂語動詞。 只有選a. flow 是正確的;b. flowed 是過去式,在疑問句中已經(jīng)用助動詞did 提問了,就不應(yīng)該用過去式了;c. flew 是fly(飛)的過去式,既不合乎題目意思也不合乎時態(tài);d. fly 詞意思不正確。
    8. d
    a. sing songs(唱歌), b. tell stories(講故事), c. play(玩) 這3個選擇都不能同前面的They cooked a meal 構(gòu)成因果關(guān)系,因此不合乎邏輯。 只有d. eat(吃)能與They cooked a meal 構(gòu)成因果關(guān)系,所以選d.
    9. d
    本句是對前一句The boys had put out the campfire(孩子們撲滅了篝火)的解釋說明.
    a. switched on(打開電源)
    b. on fire(著火)
    c. on (打開的),指電源而不是指火
    d. alight(著火的,照亮的)是正確的.
    10. c
    只有選c. were very quiet(很安靜)才與前面的They crept into their tent(他們鉆進帳篷)意思相配。因為creep有躡手躡腳的含義。a. made a lot of noise(制造很多噪音),b. ran quickly(快跑),d. were very noisy(非常吵鬧)這3個選擇都不合乎邏輯。
    11. c
    只有c. comfortable(舒適的)符合句子的要求,因為系動詞were 后面應(yīng)該跟形容詞做表語,說明sleeping bags 的狀況. 其他3個選擇詞性不對,不符合題目意思.
    12. c
    只有c. deeply 才與前一句soundly 的意思相同。
    a. noisily (吵鬧地),b. fast (快)都不合乎題目意思。
    d. good (好的)是形容詞, 不能修飾動詞slept.
