典句精讲

What Is a Tornado?

1.Almost all of them occur in the US,in the area from Texas in the southeast to South Dakota in the north.

在美国,大部分龙卷风发生在从东南的得克萨斯州到北部的南达科他州。

【巧解句构】本句主干部分为almost all of them occur in the us,其余的作地点状语。

【要点剖析】almost副词"几乎,差不多",指时间,空间,程度上差距不大,可与否定词no,none,nothing,never等连用,表示"几乎没有";同all,always,every连用时,可同nearly互换。

【拓展延伸】把握almost和nearly的区别:

almost和nearly都有"几乎、差不多"的意思,有时可换用。如:

He's almost/nearly six feet tall.他差不多有六英尺高。

almost可与否定词no,none,nothing,never等连用,但不可与not连用;而nearly一般用来修时表示肯定意义的词语,不能与否定词no,none,nothing,never等连用,但可与not连用。如:

She said almost nothing.她几乎什么都没说。

We aren't nearly ready for the inspection.对检查一事,我们还远未准备好.

2.They can destroy houses,but leave the furniture inside exactly where it was.

它们能毁掉房子,却把房内的家具留在原处。

【巧解句构】but连接can destroy和leave两个谓语动词,houses为destroy的宾语,the furniture为leave的宾语,inside为宾语补足语,where it was为地点状语从句。

【要点剖析】leave是及物动词,意思是"使......继续处于......状态",可以接副词,分词,介词短语,从句等作宾语补足语。如:

I've told you to leave my things alone.我已经告诉过你不要动我的东西。

I've left my gloves on the bus.我把手套落在公共汽车上了。

3.On average,there are 800 tornadoes in the US each year,causing about 80 deaths and 1500 injuries.

平均说来,美国每年有800次龙卷风,造成大约80人死亡和1500人受伤。

【巧解句构】本句是there be结构,表存在,主语与be动词接近的名词保持一致。800 tornadoes为名词,作主语,故be动词用are。

causing about 80 deaths and 1500 injuries为现在分词短语,进一步说明情况,可以改写成由which引导的非限制性定语从句:which cause about 80 deaths and 1500 injuries。

【要点剖析】1)death n. 死,死亡,既可用作可数名词又可用作不可数名词。如:

He remained in good health right up to his death.他直到死,身体状况一直都很好。

Drunken driving causes thousands of deaths every year.

酒后开车每年都造成成千上万人死亡。

2)cause v.导致、引起。用于搭配:

cause sb. to do sth.导致某人干某事

The heavy rain caused the flood.

大雨引起了洪水。

cause sb. sth.给某人带来了某事

This car has caused me a lot of trouble.这辆车给我带来了许多麻烦。

n.原因

The heavy rain was the cause of the flood.

大雨是导致洪水严重的原因。
