When will you take part in the meeting?你將什么時候參加會議？

alive, living, lively

alive是表語形容詞，意為“活著的”，“在世的”，它既可以修飾人也可以修飾物。作定語時，應將其放在被修飾的名詞后面。例如： They were alive. 他們都還活著。

living作形容詞意為“活著的”，主要用作定語，常置于名詞之前，有時也可置于名詞之后。the living表示“活著的人”；作名詞意為“生計”。例如：

Every living person has a name.每一個活著的人都有一個名字。

lively意為“生動的”，“活潑的”，“充滿生氣的”，用作表語或定語，可以用來修飾人或物。例如：

The sports ground is lively with all sorts of ball games. 運動場上要進行各種球類比賽，呈現出一派生氣勃勃的景象。

The boy has a lively mind. 這男孩頭腦靈活。

how long, how soon

how long是“多久（時間）”的意思，用于對時間段提問，詢問某一動作進行多長時間了。例如：

It takes two months to finish the work.

→How long does it take to finish the work?

how soon是“過多久”的意思，用于將來時態的問句中，回答用“in + 一段時間”的時間狀語。例如：

→How soon can you be ready?
