2．趕快！上課時間到了．
Hurryup!It'stimefor us to start our class．

分析 up； time．

解答 答案：up； time．第一個空是要譯出趕快，用hurry up，第二個空是要完整表達做某事的時間到了結(jié)合前面的it's和后面的動詞不定式用it's time （for sb）to do sth，故答案是up； time．

點評 it is time for sth．該是做某事的時候了
it is time （for sb．） to do sth．對某人來說該是做某事的時候了．
It is time for class．=It is time to have classes．

7．I'm Jane，from America．I can not sleep well and I always wake up several times during the night．I know for a fact that there are many other people who have trouble going to sleep，too．So，I've collected some advice I've received over the past few months that have not only helped me get to sleep faster，but helped me get better night sleeps．
Have regular sleep habits
Go to bed at the same time every night．Try not to break this habit on weekends when you may be made to stay up late．Wake up at the same time every day．If you're getting enough sleep，you should wake up naturally without an alarm．
Turn off your computer
Don't play on the computer for half an hour before you decide to sleep．Studies show that it is bad for the quality of your sleep．Read a book or listen to some light music to prepare your body for sleeping．
Have a nice bedroom
A clean environment helps people to be happy and relaxed．Make sure that you have turned off all light that might come into your room，and that the temperature is comfortable．
Exercise often
Exercising will help you to fall asleep more easily，so walk out for 45 minutes every day and you will sleep better at night．But don't do it just before you go to bed-you won't be able to sleep!
Eat properly
Eat only a little for supper．A full stomach may make it much harder for you to sleep．
任務(wù)型閱讀：根據(jù)短文內(nèi)容，填寫下列表格，每格只填一詞．
Advice on How to （71）sleep Well
