Unit 8重点句子解析
1. I had a bowl of noodles, and I used chopsticks and a spoon instead of a fork and a knife.
短语instead of 意为“代替”，后接名词、代词、V-ing形式作介词宾语，这个短语在句中作状语，修饰前面的动词。如：
We stayed at home instead of going out to play. 我们呆在家里了，而没有出去玩。
2. But we do have lots of fun.
句中的助动词do起强调作用，后加动词原形；如果主语是单数第三人称单数，则用does加动词原形，如果强调过去时的动作则用did加上动词原形。如：
Danny does like Chinese food. 丹尼真的喜欢中国食品。
They did visit the museum yesterday. 他们昨天的确参观了博物馆。
3. Although sayings are usually simple and easy to remember, they are full of deep meaning.
句式“be + 形容词 + 不定式”表示“很……做某事”，短语be full of 与be filled with 同义，意为“充满、装满”。
