[多项选择]我们青年人要像夏天的太阳一样，有一颗赤热的心，要勤奋，要勇敢，还要坚韧，除去懒惰怯弱的习惯与不肯吃苦的念头，到成年的时候，才能负担责任，创立大事业，收到良好的结果。
夏天的清晨是何等舒适和快乐。我们应该早起，可以运动，可以在花间行走，看看植物的生活状况，看看天空变幻的云霞。
懒惰怯弱与不肯吃苦的人，总有他们的理由；夏天太热，不宜读书；蚊子咬人，不宜读书；清晨最好的时候，最好是睡在床上。
如果睡眠是人生的幸福，那么终日睡眠好了，何必生活呢
大家来利用壮年一样的夏天。

参考答案:
We youth should be like the summer sun with a red hot core; we should be diligent, gallant and persistent, and be capable of doing away with the habit of laziness and timidity and the thought of shirking hardship, so that when we grow up we may be able to carry heavy responsibilities, initiate great enterprises and make good in our undertakings.
How refreshing and gay in the early morning of summer! We should rise early; we could have a little exercise, read a book, stroll beneath the trees and amidst the flowers, and observe how plants grow and how the clouds changing their patterns in the sky.
The indolent, the craven and evasive usually have their excuses--the summer weather is too hot to study; mosquitoes are too annoying; the early morning is the best time to lie in bed.
If sleep is a complete blessing in one’s life, then why not sleep all day Why live
Come, let us all make use of this youthlike summer time!
