  (四)词汇(vocabulary)

  1. 部分动词的过去式

  took off(起飞、脱下)  arrived(到达)  landed(着陆)

  got out(下车、下来)   shouted(喊叫)  climbed(爬)

  happened(发生)        ran away(逃跑)

  5. another(另一个)  jump down(跳下来)   go up(向上去)    in front of(在……前面)

  (五)重点、难点分析

  1. 过去进行时:表示在过去某一时间内正在进行的动作。

  构成:was / were + 现在分词(其中was是am、is的过去式,were是are的过去式)

  eg. 1) i was doing my homework then . 那时,我正在做作业。

  2) he was cooking in the kitchen at 12 o'clock yesterday .昨天12点,他正在厨房烧饭。

  用法:1)过去进行时表现过去某一时刻正在进行的动作。

  eg. she was writing a letter when i came in .我进来时,她正在写封信。

  2)过去进行时还表示过去某阶段正在进行的动作。

  eg. they were waiting for you yesterday .他们昨天一直在等你。

  2. 现在分词的构成

  1)一般动词在词尾加-ing,读[iη],如go→going。

  2)以不发音字母e结尾的动词,先去掉e,再加-ing。

  come→coming     make→making    write→writing

  3)以重读闭音节结尾的动词,如果末尾以一个辅音字母结尾,应先双写这个字母,再加ing,x和w结尾的除外。 如get→getting   swim→swimming  show→showing

  4)以字母y结尾的单词,直接加ing。如carrying、playing、

  5)以字母ie结尾的动词,变ie为y,再加ing。如 die→dying   lie→lying

  6)以元音字母加e结尾,或以e结尾,且e发音的动词,直接加-ing 。如  see→seeing  be→being

  3. 使用进行时态的注意事项

  1)一些动词,如see、hear、love、like、know、remember;understand、have等表示感情、知觉和状态的词,一般不用于进行时态。

  2)在there和here引起的句子中,常用一般现在时代替现在进行时。

  eg. here comes the bus .

  there goes the bell .

  4. 过去进行时和一般过去时的区别

  1)过去进行时表示过去正在进行的动作,而一般过去时则表示一个完整的动作。如:

  they were writing letters to their friends last night .昨晚他们在写信给他们的朋友。(没有说明信是否写完)

  they wrote letters to their friends last night .他们昨晚写了信给他们的朋友。(表达了他们已写好的意思,整个写的过程已完成。)

  2)当动作延续较长时间时或表示厌烦、赞美等感情色彩时,常用过去进行时表示。如:

  he was thinking more of others than of himself .他考虑别人的比考虑自己的多。(表示说话者赞扬的口气)

  the boy was always making trouble then .那时,他总是惹麻烦。(表示说话者厌烦的口气)

  5. 以when和while引导的时间状语从句

  1)延续性动词和非延续性动词

  延续性动词指动作可以延续一段时间,而不是瞬间结束。如:work、study、drink、eat等。

  非延续性动词指动作极为短暂,瞬间结束。如:start、begin、hit、jump、knock等。

  2)在本单元中,出现了以when和while引导的时间状语从句。

  <1> when表示“当……的时候”。从句中既可用延续性动词,又可用非延续性动词,这些动词既可以表示动作,又可表示状态。从句中的动作既可和主句的动作同时发生,又可在主句的动作之前或之后发生。如:

  mary was having dinner when i saw her .

  the boy was still sleeping when his mother got home yesterday morning .

  <2> while表示“在……的时候”、“在……期间”。它强调主句的动作与从句的动作同时发生或主句的动作发生在从句的动作过程中。while从句中必须是表示动作或状态的延续性动词。如:

  the weather was fine while we were in beijing .

  she called while i was out .

  如果主句的动作在从句的动作过程中发生,从句常用进行时。如。

  while we were swimming someone stole our clothes .

  don't talk so loud while others are working .

  总结:

  <1> when可指时间点,又可指时间段,从句中可用延续性动词,也可用非延续性动词。

  <2> while总是指一个时间段,从句中必须用延续性动词。

  6. ufo:unidentified flying object 不明飞行物

  1947年6月24日,一名叫做阿诺德的美国商人,架着一架小型飞机在华盛顿州上空,发现一组巨型不明飞行物以1000公里左右的速度,同他一起在空中翱翔。阿诺德的有关目击报告第一次引起公众的兴趣,从此“飞碟”或ufo便迅速流传开来。

  7. the boy was walking down the street when a ufo landed .当一个ufo着陆的时候,那个男孩正在街上走。

  land n. 陆地,地面 v. 登陆,降落

  8. at around ten o'clock in the morning .

  在上午,在早晨 in the morning

  在下午 in the afternoon

  在晚上 in the evening

  在十点钟左右 at around ten o'clock

  在正午 at noon

  在晚上 at night

  *请注意介词的不同

  9. take off

  (1)脱下 eg. please take off your coat . it's warm in the room .请脱下大衣,屋子里面很暖和。

  (2)起飞 eg. the girl was eating the icecream when the ufo took off .当ufo起飞的时候,那个女孩正在吃                    冰激淋。

  10. talk on the phone 通过电话谈话

  注意:这里要用介词on

  11. get out of the shower 洗完澡出来

  get out of the ufo 从ufo中出来

  get out 出来

  12. i was walking down the street when a ufo landed right in front of me .当一个ufo恰好落在我面前的时候,我正在街上走。

  right在这里是副词,“恰好”“正好”的意思,表示强调。

  例如right now(现在) right here(就在这儿)

  right in front of me 恰好在我前面

  13. be surprised (某人)很吃惊

  eg. he was surprised when i saw him .我看见他的时候,他很吃惊。

  另外,surprise sb. 指“让某人吃惊”

  eg. i don't want to surprise you .我不想让你吃惊。

  14. before the police arrived , the alien left the shop .在警方到达之前,外星人离开了商店。

  before“在……之前”引导时间状语从句

  15. be scared (某人)给吓坏了,害怕了

  eg. he was scared when he heard the strange voice .当他听到了那个奇怪的声音,他害怕了。

  16. run away 逃跑

  17. walk around the station 在车站走来走去

  18. she didn't think about looking outside the station .她没想到过要往车站外面看一看。

  think about 考虑

  looking outside the station 是动名词短语,做think about的宾语。

  look outside 往外看

What were you doing when the UFO arrived教案 篇2

  review of units 1—3

  一. 重点词汇

  1. as

  as作为连词,引导时间状语从句,“当……的时候”,一般用于一般过去时。

  例如:

  as he explored the sea,he took a lot of pictures.

  他在探海时,拍了许多照片。

  还可以引导原因状语从句,只说明一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句通常放在句首,有时也放在句尾。

  例如:

  as the car is expensive,we can’t buy it.

  由于汽车太贵,我们买不起。

  as everybody has come,we can set off.

  既然大家都到了,我们可以动身了。

  as soon as 一……就

  例如:

  as soon as he arrived in france,he called me.

  他一到法国,就给我打电话。

  as…as… 表示双方程度相等,“和……一样”。

  基本句式:

  a、主语+谓语(系动词)+as+原级形容词+as…

  例如:

  xiao li is as tall as his brother.

  小李和他哥哥一样高。

  your jacket is as new as mine.

  你的茄克衫和我的一样新。

  b、主语+谓语(行为动词)+as+原级副词+as…

  例如:

  he speaks french as fluently as you.

  他说法语和你说得一样流利。

  wang ying teaches maths as conscientiously as her sister.

  王莹教数学和她姐姐一样认真。

  2. a few;few;a little;little

  few或a few在句中修饰可数名词,后接可数名词复数;也可用来代替复数名词。其中few表示否定,意为“几乎没有”,a few则表示肯定,意为“有一些”。

  例如:

  few people lived here many years ago.

  许多年前几乎没有人住在这儿。

  look!you made a few mistakes in your homework.

  看!你在作业中出了几处错。

  little或a little在句中修饰或代替不可数名词。其中little表示否定,意为“几乎没有”,a little表示肯定,意为“有一点”。

  例如:

  —how much wine did he have last night?

  昨天晚上他喝了多少酒?

  —just a little.

  只喝了一点点。

  hung up,we have little time left.

  快点,我们没有多少时间了。

  a little还常用来修饰形容词、副词、动词,也可以修饰形容词或副词的比较级。

  例如:

  all of them felt a little tired.so they stopped to have a rest.

  他们都感到有点累,所以他们停下来休息。

  lucy runs a little faster than i.

  露茜跑得比我快一点。

  3. a little和a bit

  a bit和a little通常可互换,也可修饰动词、形容词、副词。但在修饰名词时有区别:a little可直接修饰不可数名词;而a bit则要与of搭配才能修饰名词。

  如:

  please open the windows.it's a bit hot.

  请把窗户打开,有点热。

  this morning he only had a bit of milk for breakfast.

  今天早上他早餐只喝了一点牛奶。

  注意:

  not…a little意为“非常、很多、不少”,相当于very或quite等;而not…a bit则表示“一点也不”,相当于not at all等。

  例如:

  the boy isn't a bit hungry.

  那男孩一点也不饿。

  the boy isn't a little hungry.

  那男孩非常饿。

  4. besides,except,but

  这三个词都可以用来表示转折,但是用法有所区别:

  (1)except与besides 用于肯定句时,except意为“除…外(不再有)”;besides意为“除…外(还有)”:

  例如:

  we all passed the exam besides tom.

  除了汤姆外,我们也都及格了。(汤姆也及格了)

  注意:

  besides在句中的位置较活,可放在句首,亦可放在句中或句末;而except多放在句尾。

  (2)except前几乎总有all,any,every,no及其复合词等词,而besides前面可用也可不用,依句意而定:

  例如:

  he answered all the questions except the last one.

  除最后一个问题没答外,其余问题他都答了。

  all of them went to beijing last summer besides tom.

  除了汤姆外,他们去年夏天也都去过北京。

  (3)except,but,besides用于否定句时,可以互换。

  如:

  there aren’t any other people to be considered besides/except/but you.

  除你之外,其他人将不予考虑。

  i didn’t look anywhere besides/except in your bedroom.

  除了你的卧室外,我哪儿也没去找。

  (4)but和except都可以和for连用,构成短语;也可跟 that 从句做宾语。

  如:

  l asked nothing from him but/except that he should write to me every other week.

  我只要求他每两周给我写一封信。

  you can't succeed in the exam but/except that you will work still harder.

  你若不比以前学习更用功些,是不可能考上的。

  二. 重点句型

  1. there be …

  是“某处有某人或某物”的句型表示“存在”,注意:本句型要用就近一致的原则。

  另外,there be句型有一些扩展形式:there + live(lie,stand,come,go)+主语+其它。

  如:

  (1)once upon a time,there lived a king.

  (2)there goes the bell.

  (3)on the hill(there)stands a house.

  注意此句:there will have a class meeting this thursday afternoon.是错误的。

  应将其改为:there will be a class meeting this thursday afternoon.

  对there be句型中的主语提问时,无论主语是单数还是复数都用“what’s + 地点状语?”

  如:

  there are five apples on the plate.→what’s on the plate?

  2. too…to,so…that…和enough to do sth. 的句式在一定的情况下可以互换。

  (1)在肯定句中含so … that …的复合句可以转换成含有enough to do sth. 结构的句子。

  如:

  he worked so hard that he finished the work in time.

  →he worked hard enough to finish the work in time.

  if your son feels well enough to watch tv by then,he’ll be fine after the game.

  →if your son feels so well that he can watch tv by then,he’ll fine after the game.

  (2)在具有否定意义的句中,三者可以相互转换,但应注意too…to在和enough to do sth. 与so…that…转换时,应用句中形容词的反义词或将that从句改为否定句。

  如:

  he is too young to join the army.

  →he is so young that he can’t join the army.

  或:he isn’t old enough to join the army.

  (3)如果so…that…结构中主句和从句的主语不是一致的,应在enough to do sth和too…to结构中的不定式前加上“for sb.(sth.)”的短语。

  如:

  english is so useful that all of us should learn it well.

  →english is useful enough for us to learn well.

  the maths problem is so difficult that i can’t work it out.

  →the maths problem is too difficult for me to work out.

  或: the maths problem isn’t easy enough for me to work out.

  3. like后既可接动词-ing形式,也可接动词不定式。含意却有所不同。

  如:

  he likes swimming in summer.(表示习惯爱好)

  it’s very hot. he would like to(have a)swim.

  (表示具体的一次行为):hate等也有类似的用法。

  三. 综合检测

  参考答案:

  ⅰ. 看图

  1. building

  2. scientists

  3. housework

  4. ticket

  5. parrot

  6. kitchen

  ⅱ. 单项选择

  1. 此题考查学生句子中的词语搭配。“举行运动会”为hold a sports meeting,但句中有“there”一词,决定要用there be句型,表示“某时有…”,虽然have也有“有”的含义,但它是“(某人/某物)有”故本题答案为a。

  2. 此题考查学生对助动词、情态动词的理解。will,shall,would都有征求对方意见之意,语气都很委婉、客气,但它们接的人称代词不同。will,would常接第二人称you,shall接第一人称i和we。故此题答案选c。

  3. 此题考查学生对little/ a little,few / a few的理解。a little/ little修饰不可数名词,a few/ few修饰可数名词。而a little,a few表示“有点,少数几个”,在句中有肯定含义;little/ few表示“少数”,“几乎没有”在句中有否定含义。此题中english是不可数名词,weeks是可数名词,所以答案为a。

  4. 本题考查疑问词的用法。how long指时间长短,如two days;how often问频率,如three times a day;how much问(不可数)多少;而how far问距离,而本题half an hour’s bus ride指的是距离,故选c。
