四、阅读理解
No one can change the weather. But if we read the signs around us correctly, we can tell how the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting. For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. Many people feel in their bones the coming of wet weather—they feel joints (关节). Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because of the insects which they are hunting that they fly low. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. Such rainbows come in the evening. If the stars twinkle (闪烁), then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in colour, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.

【答案】
1．when 2．while 3．While/When 4．When 5．when

根据题干可知，主句和从句都是过去进行时，用while不用when。故答案为while。
3．句意：Mary正在读书时，Lisa到了。
根据题干可知，主句是一般过去时，从句是过去进行时，从句前即可用when，也可用while；句子开头首字母大写。故答案为While/When。
4．句意：当Susan十岁时，她能够弹吉他。
根据题干可知，复合句中主句和从句都是一般过去时，表示两个单一行为，用when引导时间状语从句；句子开头首字母要大写。故答案为When。

二、完成句子（每空一词）。
【答案】
6 .What 7． When was 8． While came
9．wasn’t buying any 10． were reading
【详解】
6．句意：——昨天晚上十点你正在做什么？——我正在玩电脑游戏。
考查根据答语完成问句。答句说的是过去时间正在做的事情，问句应该是问“昨天晚上十点你正在做什么”，用疑问词what符合题意；句子开头首字母要大写。故答案为What。
7．句意：当Jack的妈妈回到家的时候，他正在沙发上睡觉。
考查对画线部分提问。画线部分“when his mother got back home”是时间状语从句，由此可知要问Jack什么时候正在睡觉，用疑问词when；原句中be动词was提前；句子开头首字母大写。故答案为When was。
8．句意：当老师进来的时候，这对双胞胎正在大声讲话。
考查改写句子。while后加延续性动词，句子可改为“当这对双胞胎正在大声讲话时，老师进来了”，第二空依旧用came；句子开头首字要大写。故答案为While；came。
9．句意：Mary正在商场里买些衣服。
考查肯定句改否定句。改写时要在was后接not构成否定句，其缩略形式为wasn’t；some在否定句中变为any。故答案为wasn’t buying any。
10．句意：这对双胞胎现在正在读一本英语故事书。
考查改写句子。时间状语改为“at that time last night”后，句子要改为过去进行时，are reading改为were reading。故答案为were reading。

11．They ________ about a comedy this time yesterday.
A．were talking B．are talking C．have talked D．will talk
【答案】A
【详解】句意：昨天这个时候他们正在谈论一部喜剧。

A．get off B．run off C．turn off D．go off

考查情景交际。I think so我也这样认为；That’s interesting这很有趣；That’s strange这很奇怪；Let me see让我看看。根据答语中的“You didn’t ”以及“I told Eric to give it to you.”可知，“我”已经让艾瑞克给你了，你却没收到，这件事很奇怪。故选C。
