It’s an hour’s practice, more or less.
I will not go to bed until I finish doing my homework tonight.
Why don’t you hand in your homework on time?
I used to study English on the radio.
Would you please say it once again?
How about listening once more?
We ought to get ready for the test.
Our teacher told us to pay attention to the blackboard in class.
I am glad that you can point out my mistake.
The teacher told us to put down something important.
I have kept studying English for ten years so far.
So long as we keep speaking English, we will speak English well.
The math problem was so hard that few students could work it out.
The harder you study, the better you will learn.
The other day, I was busy getting ready for the test.
Why not think about asking the teacher for help?
I usually start to study as soon as I wake up.
The teacher asked us to turn over and look through the next page.
