Unit 10重点句子解析
1. I love cooking, and I like creating new dishes myself.
句中的myself是反身代词作主语同位语，此时可放在句尾，也可放在主语后，故这句话还可说为：I love cooking, and I myself like creating new dishes. 如：
We can solve all the problems ourselves now. = We ourselves can solve all the problems. 现在我们自己能解决所有问题了。
2. Astronauts need to know a lot about science, Danny.
这句话中的need 起实义动词作用，后面的动词用不定式，表示“需要做……”；另，句中的a lot起副词作用，用在动词know后作状语，与very much同义；about science 是介词短语作状语。如：
She needs to clean her bedroom at once. 她需要马上打扫一下她的卧室。
You can learn a lot about music in this school. 在这所学校你可以学到很多有关音乐的知识。
3. If not, decide what things must be done and what can be dropped from your list.
句中的must be done和can be dropped 都是带有情态动词的被动语态，构成方法是“情态动词 + be + 及物动词过去分词”。如：
All the rooms must be cleaned every day. 所有的房间每天都必须打扫。
