What is a tornado?
A tornado is a rotating (旋转的) column of air from a thunderstorm to the ground.The most violent have winds of more than 400 kilometres per hour.Almost all of them occur in the US,in the area from Texas in the southeast to South Dakota in the north.Tornadoes can pick up cars,trains and even houses and put them down in the next street,or even in the next town.They can take the fur off the back of a cat and the feathers off a chicken.They can destroy houses,but leave the furniture inside exactly where it was.
①On average,there are 800 tornadoes in the US each year,causing about 80 deaths and over 1,500 injuries.The worst tornado of all time occurred in 1925,affecting three US states:Missouri,Illinois and Indiana.②By the time it ended,about 700 people had been killed and more than 2,000 had been injured.What is a hurricane?
Hurricanes are strong tropical
(热带的)storms,and they usually

Ocean,the Caribbean Sea and
the Gulf of Mexico.There are
violent winds of 120 kilometres per hour or more,which cause huge waves,heavy rain and floods.There are on average six Atlantic hurricanes each year and they usually affect the east coast of the US from Texas to Maine.The worst hurricane disaster of all time occurred on the 8th September, 1900 in Galveston,Texas.Winds of about 200 kilometres per hour and five-metre high waves hit the city.The disaster killed 6,000 people in a population of 37,000 and destroyed 3,600 buildings.An extraordinary event

century Irish actor who went to liv
e in Canada.③He then moved to New York,where he became famous.By the late 1890s,he had moved to Galveston, where he died in 1899,a year before the hurricane struck.The cemetery where Coghlan was buried was destroyed by the hurricane and Coghlan's coffin ended up in the sea.Eight years later,the coffin was found by fishermen in the sea on Prince Edward Island in the east of Canada.The Gulf Stream had carried it 3,000 kilometres up the eastern US coast to Prince Edward Island.Coghlan travelled back to Canada,after he had been buried in Texas!Ⅰ.阅读短文,判断正(T)误(F)

不管有多远,我今晚也要开车到那儿去。however用法小结:
(1)adv.“无论如何,不管怎样”。用来修饰形容词或副词,其语序为:however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能,用以引导让步状语从句。Phone me when you arrive, however late it is.
你到达之后就给我打电话,不论多么晚也要打。
However much he eats, he never gets fat.
不管他吃多少,他永远吃不胖。

However /No matter how hard I worked, she was never satisfied. 无论我多么努力地工作,她从来没满意过。(2)conj.“可是,仍然”表示转折,尤其用于谈及一个既成事实时。可放在句首、句中或句末,通常用逗号与句子其他成分隔开。
My father, however, did not agree.
但是,我父亲不同意。
My room is small; however, it's comfortable.
我的房间很小,但却很舒服。

他说情况如此,可是他错了。【温馨提示】
however不能像 but(但是)那样直接连接两个句子。
我们都已尽了最大的努力,不过我们还是输了。
误:We all tried our best, however we lost the game.
正:We all tried our best, but we lost the game.
正:We all tried our best; however, we lost the game.
正:We all tried our best. However, we lost the game.【感悟高考】
To be great,you must be smart,confident,and,________honest. (2011·安徽,24)                   
A.therefore B.above all
C.however D.after all
解析 句意:要想伟大,你必须聪明、自信,最重要的是诚实。 therefore“因此”;above all“最重要的是,尤其是”;however“然而,但是”;after all“毕竟,终究,归根结底,(解释或说明理由)别忘了”。选above all。
答案 B(3)conj. “无论以何种方式,不管怎样”,引导方式状语从句。

①You should try to get a good night's sleep________much work you have to do.
A.however B.no matter
C.although D.whatever
解析 however作连接副词时,与no matter how相当,后接形容词或副词,意为“无论……”“不管……”。句意:不管你有多少工作要做,你都应该好好休息一个晚上。
答案 A②He tried his best to solve the problem,________difficult it was.
A.however B.no matter
C.whatever D.although
解析 因difficult是形容词,修饰形容词要用连接副词however(无论如何,不管多么),引导一个让步状语从句。
答案 A③________ rich one may be there is always something one wants.
A.Whatever B.Whichever
C.However D.Wherever
解析 however 用于修饰形容词rich,在意义上相当于no matter how。
答案 C2.I was about to go back to sleep when suddenly my bedroom became as bright as day.
我刚要再睡,突然我的卧室亮如白昼。
when 在此处是并列连词,表示“正在那时;这时”,引起一个意想不到的动作。be about to do... when...表示“正要做……,这时……”。
I was about to wash my face when he came back.
当他回来的时候我正要去洗脸。

新学年开学在即。
误: The medical team is about to start immediately.
正: The medical team is about to start.
医疗队就要出发了。be on the point of doing sth...when...

比尔刚刚上床睡觉,突然电话铃响了。
表示将要发生的动作,还可以用下面的结构:(1)be going to do 表示事先经过考虑、打算去做某事或有明显的迹象要发生某事,它可用于条件状语从句中表示将来,而 shall/will 则不行。shall/will 可表示临时作出决定。
I am going to return to my native country in three years.
三年之后我要回到祖国。(2)be to do表示职责、义务、意图、约定、可能性或注定要发生的动作。
The students are to meet at the school gate tomorrow.
明天学生们将在学校大门口集会。
(3)英语中 begin, come, go, leave, sail, start, arrive, return, end, open, close 等表示一个预计将要发生的动作或情况,可用一般现在时表将来。这一动作时间比较固定,基本已成为规律。
—When does the bus start?公交车什么时候出发?
—It starts in ten minutes.十分钟之后。(4)英语中 go, come, begin, start, leave, arrive, return, take off 等动词(词组)可用现在进行时代替将来时,表示一个预计将要发生的动作,这种用法要带一个表示将来的时间状语。

答案 C③We were________ to go out for camping ________ it began to rain.
A.hardly;than B.around; as
C.about; when D.nearly; while
解析 be about to...when...“正准备……这时……”,when作“这时”讲,它起并列连词的作用,连接两个并列的分句。
答案 C3.The other two climbed down into the crater to collect some lava for later study,but this being my first experience,I stayed at the top and watched them.另外两人攀下火山口去收集供日后研究用的岩浆,我是第一次经历这样的事,所以留在山顶上观察他们。
this being my first experience是“代词+v.-ing”构成的独立主格结构,在句中作原因状语。分词短语作状语时,它的逻辑主语一般和句子的主语保持一致,但有的分词短语有自己的逻辑主语,这种结构称为独立主格。常用来表示时间、原因、条件、行为方式或伴随情况等。Her work being done, she sat down for a cup of tea.
她干完了活,坐下来喝茶。
The condition being favourable, he may succeed.
若条件有利,他或许能成功。

【单项填空】
①The children went home from the grammar school,their lessons________for the day.
A.finishing B.finished
C.had finished D.were finished
解析 考查名词的独立主格结构。名词短语their lessons和动词finish之间是被动完成关系。故用过去分词finished。
答案 B②Everything________into consideration,they ought to have another chance.
A.to take B.taken
C.to be taken D.taking
解析 everything与take之间为动宾关系。故用过去分词。
答案 B③—Wow!It snowed last night.What a nice world!
—You're right.But it's more difficult to find my missing keys with snow________the ground.
A.covered B.cover
C.to cover D.covering
解析 考查with复合结构作宾补的非谓语动词形式。snow和cover在逻辑上是主谓关系,因此用现在分词。
答案 D④The bus was crowded with passengers going home from market, most of________carrying heavy bags and baskets full of fruit and vegetables they had bought there.

C.whom D.which
解析 most of them carrying...为独立主格结构,相当于 and most of them were carrying...,也可改为:most of whom were carrying。注意改动后连词 and 的使用和动词 were的使用。
答案 A
