Language points

1. …, which freezes

when cooled. （果冻）被冷却后会变硬。(line19) when cooled 为when it is cooled 的省略结构

when/while /once/unless/ if 等连词所引导的从句中的主语与主句主语相一致，且从句中含有系动词be 时，从句中的主语和

系动词be可省略，形成“连词+分词”

结构。

2. Only after you have had that recognition can you say that you are truly an inventor. 只有你得到这种认可，你才可以说是一个真正的发明家。(line41) only 修饰状语，置于句首，主句的语序需要倒装。此句如改成正常语序应是：You can say that you are truly an inventor only after you have had that recognition.

又如：

Only by working hard can we pass the exams. Step Ⅴ
