参考答案及试题解析
1.What date
【解析】句意:今天是9月2日。划线部分September 2nd表示“9月2日”,是具体日期,应用what date“什么日期”提问。故填What;date。
2.What were
【解析】句意:数学老师进来时,学生们正在讲话。划线部分表示正在做的事情,对此提问用疑问词what,were放在疑问词后,故填What;were。
3.What doing
【解析】句意:我回家时,妈妈正在做饭。划线部分表示过去某个时刻正在做的事情,对此提问用疑问词what,was doing是过去进行时的结构,故填What;doing。
4.What was doing
【解析】句意:我遇见汤姆时,他正在等公共汽车。分析句子可知,本句是过去进行时,画线部分是动作,对其提问,应用what,同时把be动词was提到主语Tom前,第三空用doing代替画线部分动作。故填What;was;doing。
5.What doing
【解析】句意:不明飞行物到达时他正在睡觉。画线部分是动作,对其提问应用特殊疑问词what,另外本句是过去进行时,所以第二空应用doing代替sleeping。故填What;doing。
6.What doing
【解析】句意:当我到家时,妈妈正在给花园浇水。画线部分watering the garden表示当时正在进行的动作,应用what来提问,位于句首,首字母要大写,句子采用过去进行时,应用doing来代替动词watering。故填What;doing。
7.was doing
【解析】句意:暴风雨来临时,那个女孩正在马路上奔跑。划线部分“was running on the road”表示“正在马路上奔跑”,对过去正在做的事情提问用what was/were sb. doing ;主语“the girl”为名词单数,应用was。故填was;doing。
8.What was
【解析】句意:地震发生时, 蒂米正在睡觉。画线部分was sleeping表示过去某个时间正在发生进行的动作,应用what来提问,be动词was提到主语前。故填What was。
9.What was doing
【解析】句意:他妈妈回来时,他正在看电视。划线部分是做的事情,需问“做什么”,用what引导特殊疑问句,首字母大写,be动词“was”提至主语前,do“做”,用现在分词形式doing与was构成过去进行时。故填What;was;doing。
10.When did begin
【解析】句意:在19世纪早期,第一列火车开始载客。划线部分表示“时间”,所以用when提问;原句时态为一般过去时,且句中没有be动词或情态动词,所以借助助动词did,置于疑问词之后,动词began变为原形begin。故填When;did;begin。
11.What were
【解析】句意:昨天你打电话给我的时候,我正在准备今天的考试。根据划线部分“was preparing for today’s exam”正在准备今天的考试。可知应该用疑问词what,时态为进行时,再注意到从句时态为过去时,可知主句时态也应为过去时,综合可知主句时态为过去进行时(was/were+现在分词),主语为you,故填What;were。
12.rained heavily/hard
【解析】句意:上周末下了一场大雨。根据原句可知,时态是一般过去时,结合题干可知,第一空应填谓语动词rained“下雨”,第二空填“大地”修饰动词rained,修饰“雨下得大”可以用副词heavily/hard。故填rained;heavily/hard。
13.snow heavily
【解析】句意:明天会有大雪。其同义句表达为“明天将会下大雪”,will后面接动词原形,snow“下雪”,动词,修饰“雪下得很大”用副词heavily,故填snow;heavily。
14.stayed awake
【解析】句意:当时我没有睡着。fall asleep“入睡”;not fall asleep“没有入睡”=stay awake“保持清醒 ”;原句是一般过去时。故填stayed;awake。
15.in silence
【解析】句意:我们应该在会议室里保持安静。原句“keep silent”表示“保持安静”,silent“安静的”表示状态,相当于in silence“安静地,沉默地”。故填in;silence。
16.have/take a
【解析】句意:游客可以通过它的眼睛看风景。look at“看”,等同于have/take a look“看一看”,情态动词can后跟动词原形。故填have/take;a。
17.suddenly changes
【解析】句意:印度到了10月份,天气突然从湿润变得干燥了。题中用的a sudden change表示一个突然的变化,是名词短语,因为change 也可以作动词,所以也能用一个副词suddenly来修饰它,变成change suddenly的形式;主语it是第三人称单数形式,谓语动词用第三人称单数形式,故填suddenly;changes。
18.has area
【解析】句意:法国面积超过26万平方英里。in size=have/has an area of意为“面积是……”。时态是一般现在时,故填has;area。
19.have difficulty/trouble/problems in
【解析】句意:对我来说学英语很难。与之同义的句型“sb. have difficulty/trouble/problems in doing sth”,其意思是“在做某事方面有困难”。句子的主语是“I”,所以谓语动词用have。故填have difficulty/trouble/problems in。
20.when saw
【解析】句意:艾伦在路上走的时候看见了不明飞行物。原句还可以表达为:当艾伦看见不明飞行物的时候,正在路上走着。用when来引导时间状语从句,其结构为:主句(过去进行时)+when引导的时间状语从句(一般过去时)。故填when;saw。
21.didn't until
【解析】句意:戴夫的父亲昨晚回家后上床睡觉了。原句是after引导的时间状语从句,转换为同义句“戴夫的父亲昨晚回家后才上床睡觉”,用not ...until...句型,原句是一般过去时,助动词用didn't。故填didn't;until。
22.wasn’t buying any
【解析】句意:Mary正在商店里买些衣服。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。故填wasn’t;buying;any。
23.wasn’t practicing
【解析】句意:电话铃响时,简在练习小提琴。根据原句中“was practicing”可知时态为过去进行时(was/were+doing),改为否定句,应把was变为wasn’t。故填wasn’t;practicing。
24.with the window open
【解析】句意:那个男人正在睡觉。窗户是开着的。合并为一句时,表示窗户开着的状态,可用with的复合结构with+名词+形容词,with the window open“窗户开着”。故填with;the;window;open。
25.wasn’t talking
【解析】句意:当泸定地震发生的时候,Jenny正在打电话。分析原句可知,主句时态是过去进行时,结构是was+动词-ing形式,变成否定句,只要在was后加not,其他部分保持不变,故填wasn’t;talking。
26.He said that light travels faster than sound.
【解析】句意:他说:“光比声音传播得快。”此处改为宾语从句,宾语从句为陈述句,所以用that引导宾语从句,主句为He said that...;从句为客观事实,用一般现在时,且用陈述语序,故从句为light travels faster than sound。故填He said that light travels faster than sound.
27.Were watching
【解析】句意:下雨的时候,我正在看鸟儿。句子为含有be动词的一般疑问句,且时态为过去进行时态,变一般疑问句时,be动词提前,主语为“you”,所以句首be动词为were;其后跟watching。故填Were;watching。
