书面练习参考答案摘要写作
The boys put up their tent in the middle of a field and cooked a meal. After their meal they told stories and sang songs, but it began to rain, so they crept into their tent. The boys woke up in the middle of the night. The tent was full of water, so they rushed outside. A stream had formed in the field and flowed right under their tent.

多项选择题讲解
1. 选（d）。
根据课文第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才是孩子们去睡觉的原因。
（a）it was late是事实，但不是他们睡觉的直接原因；（b）they had sung songs不符合逻辑；（c）it began to rain 只是一方面原因，但不够完整。
2. 选（c）。
根据课文后两行The stream wound its way across the field and then flowed right under the tent! 只有（c）had camped in the path of a stream（在一条小溪穿过的地方露营）与课文实际情况相符，其它三个选择（a）had a good night's sleep（睡了一晚上好觉）、（b）stayed in their tent all night（整晚呆在他们的帐篷里）、（d）had camped beside a stream（在一条小溪旁露营）都与事实不符。
3. 选（d）。
（a）it put up和（b）their tent put up语序错误，宾语应该放在谓语动词的后面；（c）put up it也不正确，当宾语是代词时应该放在动词和副词之间；只有（d）put their tent up语序正确，宾语tent是名词，既可以放动词和副词之间，也可以放副词之后，所以要选（d）。
4. 选（d）。
（a）As soon不能引导状语从句，因为后面缺少as；
（b）Just as（正当）可以引导从句，但它强调两件事情同时发生，而这个句子是表示两件事一前一后发生；（c）Until（直到……为止）词义不对；只有（d）Just after（刚刚……之后）时间正确，也符合语法。
5. 选（d）。
（a）they had hunger不符合英语习惯；（b）they had hungry语法错误，hungry是形容词，它前面应该是连系动词be，而不是had；（c）they were hunger也不符合语法，连系动词were后面应跟形容词，不能跟名词hunger；只有（d）they felt hungry是正确的，动词fell后面既可以跟形容词hungry，也可以跟名词hunger。
6. 选（b）。
只有选（b）near（在……旁）才能同前一句中的by the campfire（在篝火旁）意思相同；（a）close 是形容词，后面要加上介词to；（c）besides是介词，但表示“除……之外”，词义不对；（d）at（在……）没有“在……旁”的意思。
7. 选（a）。
本句是一般过去时的疑问句，需要选正确的谓语动词。
只有选（a）flow是正确的；（b）flowed是过去式，在疑问句中已经用助动词did提问了，就不应该再用过去式了；（c）flew是fly（飞）的过去式，时态和词义都不对；（d）fly词义不正确。
8. 选（d）。
（a）sing songs（唱歌）、（b）tell stories（讲故事）、（c）play（玩）这三个选择都不能同前面的They cooked a meal构成因果关系，因此不符合逻辑；只有（d）eat（吃）才是They cooked a meal的原因，所以是正确答案。
9. 选（d）。
本句是对前一句The boys had put out the campfire （孩子们扑灭了篝火）的解释说明。
（a）switched on （打开电源开关）不符合题义：（b）on fire（着火）意思不通；（c）on（打开的）指电源而不是指火，be动词和on连在一起还有“上演”的意思；三者都不对。
只有（d）alight（着火的，照亮的）是表语形容词，在这里作表语，并同前一句意思相同，是正确的。
10. 选（c）。
只有选（c）were very quiet（很安静）才与前面的They crept into their tent（他们钻进帐篷）的意思相符，因为creep有“蹑手蹑脚”的含义。
而（a）made
a lot of noise（制造很多噪音）、（b）ran quidkly（快
跑）、（d）were very noisy（非常吵闹）这三个选择都不符合creep的含义。
11. 选（c）。
只有（c）comfortable（舒适的）最符合句子的要求，因为连系动词were后面应该跟形容词作表语，说明sleeping bags的状况。
（a）a comfort是名词、（b）in comfort是介词短语、（d）comfortably是副词，词性都不对。
12. 选（c）。
只有（c）deeply（深深地）修饰sleep才与前一句的soundly（香甜地）意思相近；而（a）noisily（吵闹地）、（b）fast（快）都不符合题义；（d）good（好的）是形容词，不能修饰动词sleep。
