2. 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。 3. 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。 4. 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。 5. 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。 Step 6 Homework 1.
