1：looks bright
2:so that
3what mean for

are outstanding

so that

what ... mean by

1.look lively

2.so that

3.what mean by

不同时态说明不同的意思！
现在进行时:What
are
they
having
for
lunch?他们正在吃什么午餐？
一般现在时：What
do
they
have
for
lunch?他们午餐吃什么？（这个有些牵强，表示他们的午餐日复一日年复一年都一样，没变过）
一般过去时：What
did
they
have
for
lunch?他们午餐吃的什么?(最佳答案之一）
一般将来时：What
will
they
have
for
lunch?他们午餐将要吃什么？（最佳答案之二）
现在完成时：What
have
they
had
for
lunch?他们进一阶段午餐吃什么？（这个也牵强，表示从过去某个时间点开始到现在某个时间午餐没变过，而且没有一个明显的现在完成时时间标志，建议不选用）
过去完成时：What
had
they
had
for
lunch?他们那阶段午餐吃什么？（这个也不建议选用，道理和现在完成时差不多)
