Future continuous & Future perfect

將來進行時&將來完成時

The future continuous (will be + ‘ing’ form) and the future perfect (will have + past participle) tenses are used to talk about events in the future. 將來進行時（will be+ ing）和將來完成時（will have+過去分詞 ）都用來談論將來要發生的事情。

Future continuous 將來進行時

• Don’t ring at 8 o’clock. I’ll be watching Who Wants to be a Millionaire.
• This time tomorrow we’ll be sitting on the beach. I can’t wait!

We use the future continuous to talk about something that will be in progress at or around a time in the future. 我們用將來進行時談論將來即將進行或者在將來一段時間會發生的事。

• Don’t phone grandma now, she’ll be having dinner.
• The kids are very quiet. They’ll be doing something wrong, I know it!

These sentences are not about the future but we can use the future continuous to talk about what we assume is happening at the moment. 這些句子不是在講關於將來的事，但是我們可以用將來進行時去談論某個時刻將“假設”發生的事。

Future Perfect 將來完成時

• Do you think you will have finished it by next Thursday?
• In 5 years time I’ll have finished university and I’ll be able to earn some money at last.
We use the future perfect to say that something will be finished by a particular time in the future. 我們用將來完成時去談論將來某個時間將要結束的事情。

We often use the future perfect with ‘by’ or ‘in’  用到將來完成時的時候，經常跟着by或者in。
• I think astronauts will have landed on Mars by the year 2020.
• I’ll have finished in an hour and then you can use the computer.

‘By’ means ‘not later than a particular time’ and ‘in’ means 'within a period of time’. We don’t know exactly when something will finish. By表示 不晚於某個特定的時間，in表示在一段特定的時間裏。我們不知道那事情究竟幾時會結束。

• I promise I’ll have done all the work by next Saturday.
We don’t know exactly when he will finish the work – maybe Thursday, maybe Friday – but definitely before Saturday.
