,我第九单元英语没学好,怎样理解这一单元重点?
解题思路: 如下
解题过程:
Unit 9 When was he born
1. too…to的含义及用法
“too…to…”是英语中常用的一种结构,其句型为“too+形容词或副词原级+to do …”,译为“太…而(以致)不能…”。它在形式上是肯定的,但在意义上是否定的。
“too…to…”本身已含有否定的意思,因此,不定式前一般不加not.
eg:
She is too young not to go to school. (×)
She is too young to go to school. (√)
她太小不能去上学。
eg: The water is too hot to drink.
水太烫不能喝。
2. start的用法
start意为“开始”后接名词,动名词或动词不定式。
eg: The old men started singing / to sing.
老人们开始唱歌。
They started the party with dancing.
他们以跳舞来开始这个晚会。
另外,start还有“开动、发动、创办、出发”等词义。
eg: My father couldn’t start the car.
我父亲起动不了那车。
start与begin同义,都是“开始”,但在表示“开动、发动、创办、出发”等词意讲时,start不能用begin.
3. When was she born? 她什么时候出生的?
be born出生于(be用过去时态形式was或were,因为人的出生多为发生在过去的事,所以用一般过去时)
eg: The great pianist was born on October 10th, 1890.
那位伟大的钢琴家出生在1890年十月十日。
-Where were you born?
你在哪儿出生的?
-I was born in Beijing.
我出生在北京。
4. record / ri /vt. 记录、记载,
record/ /n. 记录,唱片
eg: She has recorded many songs.
她已录了很多首歌。
He made a lot of records.
他做了许多唱片。
Jay sold hundreds of records lost year.
去年杰卖了成千上万张唱片。
5.
eg:
I love surfing the Internet very much.
我非常喜欢上网。
She has loving grandparents.
她有慈爱的祖父母。
Jane is a lovely girl.
简是个可爱的女孩。
6. at the age of 在…岁时
eg: At the age of 4 Mike began to write peoms.
迈克四岁时就开始写诗。
He was very clever and at the age of 15 he went to college.
他非常聪明,15岁就上了大学。
7. He spent all his free time with his grand children.
他把他所有的时间都花在他的孙辈身上。
spend意为“花费…时间/金钱”
第3单元SB 3a中:
I’m planning to spend time in the beautiful countryside.
我打算在美丽的乡村度过时光。
eg: She spent $ 500 last year.
她去年花了五百美元。
词组(A)spend …on sth 在某物(事)上花费(时间,金钱)
eg: Maria spent five yuan on the book.
玛丽亚花了五元钱在这本书上。/玛丽亚买这本书花了五元。
I often spend a lot of time on my homework every night.
我经常每天晚上花两个小时做家庭作业。
(B)spend …(in)doing sth. 花(时间或金钱)干某事
I often spend a lot of time (in)doing my homework.
Maria spent five yuan(in)buying the book.
注意,spend的主语必须是人,在第四单元中我们学过“It takes sb. some time / money to do. ”也可表示“做某事花某人多少时间/金钱”,但take的主语应是物,而不能是人。
eg: It takes me a lot of time to do my homework.
It took Maria five yuan to buy the book.
8. join -take part in两者都表示“参加”,join指“参加”某种组织。take part in 表示参加某项活动。
eg: He joined the Party at the age of 40.
他40岁时入了党。
When did your brother join the Army?
你哥哥什么时候参的军?
Do you want to take part in the sports meeting?
你想参加运动会吗?
9. when的用法:
(1)作疑问副词,意为“什么时候”
eg: When are you leaving?
你什么时候离开?
When did Tony go to the library?
托尼什么时候去的图书馆。
(2)作从属连词,引导一个时间状语从句,意为“当…的时候”
eg: When he was a small boy, he began to perform Beijing Opera.
当他是个小男孩时,他就开始表演京剧。
She toured the U.S. when she was fourteen.
她十四岁时就周游了美国。
10. 年龄表达方法
(1)用基数词表达年龄,可以加上“…years old”three years old.
(2)用when引导的从句 when I was three(years old)
(3)at the age of +基数词 at the age of three
(4)基数词+-year-old three-year-old,注意这种表达常作定语
如a three-year-old boy
学习进步!
最终答案:略
