资源描述
I learned about the inventions that led to color movies, too. 我还了解了一些发明,它们成就了彩色电影。
此处learn是“了解;获知;得知”的意思,由介词about或of引入所获知的具体内容。例如:
The children were all shocked to learn of the death of their headmaster.
得知校长去世,孩子们都十分震惊。
I only learned about the accident later. 我只是后来才得知了事故的情况。
I’ve never been camping.
我从未野营过。
此句为现在完成进行时。这一时态的结构为“have been + 现在分词”,表示从过去某一时刻延续至今的动作。在本句中,说话人使用这一时态来强调自己至今从未有过野营的经历,欠缺这方面的经验。又如:
He’s been watching TV all afternoon.
他一下午都在看电视。
We’ve been living like this ever since the birth of my little brother.
自打我小弟弟出生,我们就一直这样生活。
The most interesting museum I’ve been to is the American Computer Museum.
多音节词和部分双音节形容词最高级加most构成,前面加the。如: the most beautiful girl
The old computers were much bigger.
much可修饰形容词比较级,表示……得多。
如: much richer
a little, even, a bit也可以修饰形容词比较级。
I wonder how much more computer will be able to do in the future.
不知道将来电脑还能够做些什么事情呢。
1)wonder 表示“ (对某事)感到疑惑; 想要知道; 想弄明白; 琢磨”, 后面常接由what, how, who 或者if/whether引导的宾语从句。
e.g. I wonder how they’re getting on.
我想知道他们现在过得怎样。
I just wonder if they’ve arrived safely.
我就想知道他们是否安全抵达了。
2) 此句从句部分的原始结构是: How much more will computers be able to do in the future? 是对陈述句Computers will be able to do (much) more in the future.(电脑将来能够做更多的事情。)的提问。由于充当了宾语从句, 疑问结构改成了陈述结构: how much more computers will be able to do in the future, 即: 将助动词还原到陈述句的位置。
e.g. I don’t know when he will come.
我不知道他什么时候来。
I don’t know where he lives.
我不知道他住在哪里。
It also encourages governments and social groups to think about ways to…
encourage sb. to do sth.
鼓励某人做某事
e.g. My father encouraged me to take part in the sports meeting.
父亲鼓励我参加运动会。
Watching the tea preparation is just as enjoyable as drinking the tea itself.
看沏茶的过程和饮茶本身一样令人愉快。
-able是一个典型的形容词后缀, 可加在动词之后, 表示“可…..的; 能够……的”。此处enjoyable(能使人快乐的; 令人愉快的) 便是一例, 再如:drinkable(可饮用的), washable(可洗的), readable(可读的), usable(可用的; 可使用的)等等。<设计意图> 随着语言学习内容的拓展和加深,学生很容易对一些语言现象产生概念混淆或辨析困难的情况。因此,这样将重难点进行归纳并摘录典型例句,既动脑又动手,不仅能加深记忆,还便于学生课后复习巩固。
Grammar
