二、重难点释疑
1.He is our national hero who traveled around the earth in Shenzhouⅴfor21hours
in2003
⑴.hero可数名词，它的复数形式是在其后加es.
E.g.He is one of our country’s national heroes.
他是我们国家的民族英雄之一。

【链接】以o结尾的名词，在构成复数时有的加s,有的加es.加es结尾的名词我们可以这样记住它们—“黑人英雄喜欢西红柿和马铃薯”。

如：
Negro黑人—Negroes，tomato—tomatoes，potato—potatoes
其余的以o结尾的名词或者外来词加s构成名词复数。

如：
photo—photos radio—radios
piano—pianos
⑵.句中who traveled around the earth is Shenzhouⅴfor21hours in2003.是一个由
who引导的定语从句，修饰先行词hero.who在从句中作主语，不能省略,此处可用that.
【知识讲解】在复合句中，修饰某一名词或者代词的从句叫做定语从句。

被修饰的名词或者代词叫做先行词，从句放在所修饰词（即先行词）之后，由关系代词（which,that,who等）引导。

如：
The umbrella that you are holding is mine.你打的那把伞是我的。

先行词关系代词
当定语从句先行词是“物”时，用关系代词that或者which来引导从句，当定语从句是“人”且作从句的主语时，用关系代词who或者that来引导。

如：The foreigner that/who visiting our school is from Canada.昨天来我校参观的那个外国人是来自加拿大。

The book that/which I am reading is very interesting.我读的这本书非常有趣。

2.China is the third nation that sent a person into space.中国是第三个把人送入太空
的国家。

⑴the+序数词+名词+to do sth.意为“第……个做某事的……”。

如：
I was the first person to come to school today.今天我是第一个来到学校的人。

⑵send…into…“把……送入……里”。

如：
China will send more satellites into space in the future.中国今后将会把更多的卫星送入太空。

【拓展】send up意为“发射”；send for sb.意为“派人去请某人”；send for sth.意为“让人带来（或送来）某物”。

如：
China has sent up ShenzhouⅦsuccessfully.中国已经成功地发射了神州七号。

Her mother was ill,and she sent for a doctor.他妈妈病了，她让人去请医生了。

He sent for a new shirt.他让人带来一件新衬衣。

⑶本句中that sent a person into space是定语从句，修饰先行词nation.此句中的
that不能换为which.
当先行词被序数词，形容词最高级修饰时，关系代词只能用that,而不能用which.如：
This is the best film that I have seen.这是我看过的最好的电影。

3.It proves that China has made great progress in the space industry.这些证明了中国
在航天业取得了巨大的进步。

⑴prove v.证明，证实，其过去式是proved,过去分词为proved和proven.
①prove+that从句，意为“证明……”。

如：
This proves that I was right.这证明我是对的。

②prove to be意为“后来被发现是；最终显现为”。

如：
His words proved to be right at last.他的话最终被证实是对的。

③prove sth./sb.+adj意为“证明某人、某物……”如：
She has proved everyone wrong.她已经证明大家都错了。

⑵make progress in(doing)sth.意为“在（做）某事方面取得进步”。

in为介词，后面接名词、动名词。

如：
China has made progress in controlling pollution.中国在控制污染方面已经取得了进步。

4.It’s a space ship which was launched as China’s first lunar probe.
它是作为在中国第一个月球探测器而发射的宇宙飞船。

which was launched as China’s first lunar probe为关系代词which引导的定语从句。

当关系代词在定语从句中作主语时，定语从句的谓语动词要与先行词保持一致。

如：
Do you know those boys who are playing basketball over there.你认识正在打篮球的那些男孩吗？
The train that has just left is for Beijing.刚离开的那列火车是开往北京的。

_____________________________________________________
二、重难点释疑
1.No one knows for certain,but most people think that robots will be part of our lives.
没有人确切知道（未来的样子），但大多数人认为机器人将会成为我们生活的一部分。

⑴no one knows.不定代词做主语，谓语动词一律用单数。

⑵know/say for certain意为“确切知道/肯定地说”。

如：
I can’t say for certain how much the bike costs.我说不准这两自行车多少钱。

I know for certain that he is at home.我肯定他在家。

for certain=for sure
2.One scientist warns that if robots start to think for themselves,they will no longer want to be our servants,but our masters.有科学家警告：如果机器人开始独立思考了，他们就将不再做我们的仆人，而想成为我们的主人。

⑴warn为动词，意为“警告”。

常见的固定词组有：
warn sb.of/about sth.意为“警告某人某事。

e.g.The teacher warned us of/about those stairs.老师提醒我们注意那些台阶。

warn sb.(that)…意为“警告某人……”。

e.g.We warned them that there was a dog in the field.我们警告他们田野里有只狗
warn sb.not to do sth.=warn sb.against doing sth.意为“警告某人别做某事”。

e.g.I warned him not to walk home alone=I warned him against walking home alone.
⑵no longer,no more,not…any longer,not…any more都意为“不再”。

no longer,no more可放在谓语动词的前后（情态动词，be动词和助动词之后，行为动词之前），也可以放在句子的最后。

not…any longer,not…any more中的not是否定谓语动词的，故要放在谓语动词前；any longer或any more则放在句子最后。

no longer,not…any longer表示动作不再延续，他们必须和表示持续意义的动词一起使用；no more,not…any more表示动作不再重复出现，可以和短暂性动词连用。

如：
He no longer stays at home alone=He doesn’t stay at home alone any longer.
他不再独自呆在家里。

Time lost will no more return=Time lost will not return any more.
时间一去不复返。

⑶not…but……意为“不是……而是……”，连接并列成分。

如：
This picture is not yours but mine.这幅画不是你的，而是我的。

，
连接两个并列主语时，谓语动词的数要遵循“就近原则”。

如：
Not you but he has made a big mistake.不是你，而是他犯了个大错。
