英语语法和翻译问题 例如我想描述 昨天吃完饭后我开始学习。 可否这样说 After I fini

sea squirt: 海鞘
The next time (that) I tried sea squirt, I scraped one [sea squirt] off a pier.

The next time 时间副词引导时间状语从句

I scraped one off a pier = I scraped a sea squirt off a pier. "one"是代词，指前面所述的 sea squirt，英语修辞忌重复，所以常用 one去代替同一句句子中第二次出现的名词。

scrape 刮掉；削去
scrape A off B 由B处刮掉/除去/削去A

The next time I tried sea squirt, I scraped one off a pier.

我下一次嚐到海鞘时，是我把它从某个码头拔下来的。

用after时，因为其意已经指出动作的先后，故后面的从句即可以用完成时也可用一般时：
After I have finished / finish it, I will go back.
After he left / had left, I went home.
