急。 英语“有些人十分勤学，从他们脸上都能看出来。 他们看著书，还时不时地扶一下眼镜”怎麽说?

Someone are so deligent that you can identify this from their expressions.They are reading books attentively,and standing their glasses at intervals.

希望你可以满意！

Those who are industrious in learning could be judged from their faces. They sometimes touch their glasses when reading books.
