把“Help others out as often as you can.”变为反义疑问句

把“Help others out as often as you can.”变为反义疑问句

1）Let's引导的祈使句，其反义疑问句一般用“shall we”
e.g. Let's have a meeting, shall we? 我们开会吧，好吗？
2）由动词原形引导的祈使句或Let us引导的祈使句，其反义疑问句一般用“will”
e.g. Read the text, will you? 请读课文，好吗？
此句“Help others out as often as you can.”就是以动词原形Help引导的祈使句，所以我们一般用will you。
如果要使祈使句听起来比较委婉、客气，还可以用would you， won't you， can you， could you， can't you 等。
e.g. 1 Open the window, won't you? 请打开窗户，好吗？
e.g. 2 Wait for me, can you? 请等我，好吗？
e.g. 3 Lend me this book, could you? 把这本书借给我，好吗？
如果是否定祈使句后只能用“will you”
e.g. 1Don't forget to post the letter, will you? 不要忘了寄这封信，好吗？
如果是以Let me开头的祈使句，反义疑问句可用“will you”或“may I”
e.g. 1 Let me do it for you, may I?

will you
