14.There was something written on the spaceship
这是there be句型,由“there be+主语+过去分词结构”构成:
be动词的形式由主语决定。由于something表示单数概念,因此be动词用了was。
written on the spaceship是过去分词作后置定语,修饰something,表示被动含义,相当于that was written on the spaceship。
由于先行词是不定代词,如果转换成定语从句,必须用that引导,不能用which;此时that也不能省略。
There is nothing written on it. 上面没写东西。
15.I wonder what it means.
I wonder what it means.是引号内的句子,这也的句子称作直接引语。
wonder在此作及物动词,意为“想知道”,相当于want to know。
what it means是what引导的名词性从句,作wonder的宾语。what在此意为“什么”,引导宾语从句时从句要陈述语序,在此作means的宾语。

After all, no one else ever tells me that I look tired or that I need to go see the dentist.
毕竟,从没有其他人跟我说过我看上去很疲惫或者说我要去看牙医了。
用法辨析:no one和none的区别
none既可指人,也可指事物;作主语时,谓语可用单数,也可用复数。
None has / have arrived.还没人到。
2)none可与of连用。none of+不可数名词作主语,谓语要用单数;none of+复数名词/复数代词”作主语时谓语既可用单数,又可用复数。
None of them knows / know the answer.他们没人知道答案。
None of the money is mine.这钱没有一点是我的。

他教导我们把人民的利益放在最重要的位置。
There was little else he could do. 他再没有别的什么可做了。
(2)I refuse to believe you是主句,用了refuse+动词不定式结构,表示“拒绝做某事”。refuse作及物动词意为“拒绝”:
可接名词、代词作宾语;所接宾语既可以是“事物”,又可以是“人”。
接动词作宾语时动词必须变为不定式。
She refused their invitation. 她拒绝了他们的邀请。
I think he won’t refuse me. 我想他不会拒绝我。
He refused to let me go. 他拒绝让我走。
17.The children spread their wings
spread在此是及物动词spread的过去式,意为“张开”。spread是动词原形、过去式、过去分词相同的特殊词汇。

语法点睛
1.because、since、as都可引导原因状语从句,它们的异同点如下
相同点:
because、since、as引导原因状语从句时均可置于主句前和主句后;置于主句前时要用逗号将其与主句隔开。
虽然中文的表达特点是“因为......所以......”,但because、since、as引导原因状语从句时不能和so连接的结果分句连用,两者只能选用一个。
Because Lingling was ill, she didn’t come to school. 玲玲因病没有上学。
Lingling was ill, so she didn’t come to school.玲玲生病了,所以没有上学。
不同点:
(1)because意为“因为”,语气最强,指事情发生的直接原因。
Because he was ill, he was late for school.他生病了,所以迟到了。
(2)since的语气比because弱,意为“既然”,表示显然的理由。
Since you don't like it, I' ll put it away.既然你不喜欢,我就把它放在一边。
(3)as的语气比since弱,意为“由于;鉴于”, 引导原因状语从句时表示附带说明的“双方已知的原因”。
As there was no answer, I wrote again.鉴于没回复,我又写了一封信。
知识拓展:for作并列连词,引导并列句,语气最弱。for表示“推断”的理由, 要放在主句后。
He could not have seen me, for I was not there. 他不可能见过我, 因为我不在那里。
2.because of的用法
because of是短语介词,意为“因为”,其后可接名词、代词;接动词时动词要用动名词。
because of引导的短语作原因状语时可置于句首和句中,置于句首时要用逗号将其与后面内容隔开;引导的短语作表语时主语通常是代词。
He lost his job because of his age.由于年龄关系他失去了工作。
We spent two hours waiting in the rain because of you.
因为你,我们在雨中等了两个小时。
Because of his wife being there, I said nothing about it.
因为他妻子在场,我便没提及此事。
It is all because of what you said. 那完全是因为你说的话。
重要提示:含有because引导的原因状语从句的复合句可变为含有because of的简单句。
I am very angry because you are late.
=I am very angry because of your being late.我非常生气,因为你迟到了。
考点:含有because引导的原因状语从句的复合句可转换成含有because of短语的简单句。
句型转换:将复合句改为简单句。
Diana made great success in her research because she put her effort into it.
Diana made great success in her research____ ____her effort.
点拨与析答:本题考查把原因状语从句because she put her effort into it转化成“____ ____her effort”。由于because of表“因为”,符合题干的结构和意思,因此填because of。
小贴士:owing to和due to也可表示“因为”,引导的短语在句中作原因状语,因此这道题也可写作due to或owing to。
知识拓展:表示原因的短语还有due to和owing to。
(1)owing to意为“由于”,可用在句首和句中作原因状语,也可用在be动词后作表语。
Owing to the shower,the baseball game was interrupted. 由于骤雨,那场棒球比赛中止了。
His death was owing to an accident.他死于一场事故。
(2)due to意为“因为”,只能用在句中,可作原因状语、表语、定语。
He arrived late due to the storm.由于暴风雨,他迟到了。
This accident was due to his carelessness. 这次事故是由于他的疏忽引起。
Mistakes due to carelessness may cause serious consequence.
由于粗心造成的错误可能引起严重的后果。
Speaking
口语表达归纳:
表达观点的句型
I think/believe+that引导的宾语从句表示“我认为/相信......”。
二.同意对方的看法或观点可用下列句型:
(1)So do I.我也这么认为。
(2)I agree.我同意。
(3)I think you’re right.我觉得你是对的。
知识拓展:此时还可用“I agree with you.”(我同意你的看法。)和I can’t agree more. (我再同意不过了。)
三.不同意对方的看法或观点可用下列句型:
(1)I don’t agree.我不同意。
(2)I think you are wrong.我觉得你是错的。
(3)I disagree.我不同意。
知识拓展:此时还可用“I don’t agree with you.”/“I disagree with you.”(我不同意你的看法。)
口语运用(以“外星人将成为我们的朋友。”和“外星人比我们更聪明。”为示例)
—I think that aliens will become our friends.我觉得外星人将成为我们的朋友。
—So do I.我也这么认为。
—I believe that aliens are cleverer than us.我相信外星人比我们更聪明。
—I think you are wrong.我觉得你是错的。
More practice
1.There were the bodies of three aliens lying on the grass.
这是there be句型,由“There be+主语+V-ing”构成,表示“有...正在做某事”,其中:
be动词的形式由主语决定。由于the bodies表示复数概念,因此be动词用了复数were。
lying on the grass是lie的现在分词短语,作主语补足语,是the bodies of three aliens 发出的动作。
(3)该句型表达主动含义,名词和V-ing之间是逻辑上的主谓关系,强调动作正在进行。
There is a monkey climbing the tree.有一只猴子正在爬树。
There are some men swimming in the river.有一些人正在河里游泳。
Culture corner
It is about aliens from Mars(called“Martians”)attacking the Earth.
该句中有两个介词短语。
about aliens...attacking the Earth是about引导的介词短语作表语; from Mars是介词短语作后置定语修饰aliens。
attacking the Earth是现在分词短语,作宾语补足语修饰aliens from Mars。该分词短语是aliens发出的动作。
The film is about a group of earthlings seeking for places to live in the outer space.
这部电影讲述一群地球人在外太空寻找居住空间的故事。
who is called the“Father of Science Fiction”
(1)H.G. Wells作同位语修饰the English writer,起补充说明的作用。此时要用逗号将其与前面内容隔开。
(2)who is called... Fiction”是who引导的非限制性定语从句,修饰the English writer。
1)who引导非限制性定语从句要修饰表“人”的词。
2)它要置于句中和句末;置于句中时要用逗号将其与前后内容隔开;置于句末时要用逗号将其与前面内容隔开。
The man,who always helps me,is called Kent.那个总是帮助我的男人名叫肯特。
This writer is called Amy,who is very beautiful.
这个作家叫艾米,她长得非常漂亮。
重要提示:that不能引导非限制性定语从句。因此如果先行词是人,且其后跟有非限制性定语从句,此时该从句只能用who引导,不能用that引导。
考点聚焦
1.考点:考查receive表“收到”,强调客观上收到,不表示主观上愿意接受;accept表“接受”,指主观上愿意接受的区别。
—Would you please see the film Iron Man 3 with me tonight, Kate
—I'd love to, but I've ________ Linda's invitation to dinner.
A. suffered B. earned C. received D. accepted
点拨与析答:题干意为“—凯特,请你今晚和我一起去看电影《钢铁侠3》,可以吗?—我想去,但我____琳达的邀请去吃晚餐。”根据句意和选项,可判断本题应填表“接受”的accepted,指主观上接受了琳达的邀请,因此选D。
2.考点:考查wake up表“醒来”,其后不接宾语;表“叫醒”,接代词作宾语时代词要放在up之前的用法。
(1)Please______before six thirty tomorrow morning.
A.wake me up B. wake up me C. wakes me up
点拨与析答:题干意为“请在明天早上6点30前_____。”由于题干是祈使句,要用动词原形开头;又由于wake up是“动词+副词”类型的短语,接代词时代词要放在up之前,对比选项,可知选A。
(2)根据汉语提示完成句子。
我叫醒了大明,让他早点起床。
I______ ______Daming and asked him to get up early.
点拨与析答:本题考查“叫醒”的英语表达方式。“叫醒”的英语是wake up,根据“and asked”可判断,时态要用一般过去时,因此填woke up。
3.考点:考查another用于“another+基数词+复数名词”结构;other/more用于“基数词+ other/more +复数名词”结构的用法。
—If you prefer the red evening dress, you’ll have to pay ______ 30 dollars, because it’s made of silk.

A. is B. was C. are D. were
点拨与析答:由于首句用了一般现在时,可判断这里是在谈论现在的情况,故空所在句要用现在时;又由于another+基数词+表“时间”的复数名词作主语时,谓语要用单数,故选A。
5.考点:考查discover表“发现”,指发现本来就有的事物;invent表“发明”,指创造出原本不存在的事物的区别。
从括号中选出合适的词语填空。
Alexander Graham Bell______the telephone in 1876. (invented;discovered)
点拨与析答:题干意为“亚历山大 格雷厄姆 贝尔于1876年_____电话。”结合常识可知,电话在1876年以前是不存在的东西,创造出原本不存在的事物要用invent,因此填invented。
6.考点:考查because表“因为”,引导原因状语从句交代原因的用法。
(1) We didn’t enjoy the day_____ the weather was so bad.
A. because B. though C. unless D. till
点拨与析答:题干意为“我们不喜欢这个日子,_____天气太糟了。”分析题干和选项,可判断_____ the weather was so bad说明原因,因此选A。

(2)A Spring Morning is my favorite poem_____its words are beautiful and I can feel the sense of spring in it.
A. until B. because C. Though

A. but B./ C. so
点拨与析答:题干意为“因为我今天早晨起床晚了, ______我上课迟到了。”由于前后句之间存在因果关系,句首用了because,“空”里应什么都不填,对比选项,可知选B。
8.考点:考查because of表“因为”,要接名词、代词、动名词﹔because/since/as表“因为”,要接从句的用法。
(1)He didn’t go to school yesterday _______he was ill.
A. because B. because of C. if D. so
点拨与析答:题干意为“他昨天没去上学,___他病了。”分析题干,可判读“_______he was ill”是从句;根据句意,可判断它是主句“没去上学”的原因。对比选项,because表“因为”,引导原因状语从句,符合题干要求,故选A。
(2)Mo Yan’s books have been sold out in many book stores ______ his winning of the Nobel Literature Prize.
A. because B. since C. as D. because of

(3)从括号中选出合适的词语填空。
He has to retire(退休)early______ poor health.(because;because of)
点拨与析答:由于所填词后接的poor health是名词,因此填because of。
9.考点:考查“there be+名词+V-ing”表“有...正在做某事”,be动词的形式由主语决定,强调动作正在进行的用法。
—Listen! There_____ someone____at the door.
—It must be your sister.
is; knocking B. is; knock C. are; knocking D. are; knock
点拨与析答:由于“there be+名词+V-ing”是固定句型,表“有...正在做某事”,be动词的形式由主语决定;又由于someone表示单数概念,因此选A。
小贴士:there be+名词后不能接动词原形。
