2. 情态动词在虚拟语气中的用法
情态动词用于虚拟语气中表示责备的感情色彩,用法如下:
(1)should have done表示“本来应该做某事而实际上未做”,而shouldn’t have done则表示“本不应该做某事而实际上做了”。如:
You should have told me about it earlier.
You shouldn’t have said such words to your parents.
(2)ought to have done也表示“本应该……”而ought not to have done则意为“本不应该……”。如:
You ought to have told me about it earlier.
You ought not to have said such words to your parents.
(3)needn’t have done表示“本无必要做某事而实际上做了”。如:
You needn’t have walked so quickly since time was enough.
(4)could have done表示“本来有可能……而事实上未做到”。如:
I could have come on time, but my car broke on the way.

Do you have any problem with time? Start doing these and you will see the difference.
 Write it down
Don’t rely on your memory to keep track of every little detail.    36Write down the things you need to do in a small notebook, or use online tool to create and update your “to-do” list.
●    37
Working for long periods without a break can waste your time. It is more efficient to work or study for a shorter period of time, take a break, and then go back to work. You may get more done in tow focused 45-minute sessions.
● One thing at a time
  38   Do one thing at a time, and do it well. As the Chinese proverb says, “One cannot manage too many affairs. Like pumpkins in the water, one pops up while you try to hold down the other.”
● Schedule email time
On your cell phone you get a notification every time someone sends you can email. If so, you have to check your email many, many times a day.   39  Schedule time to check your email. It doesn’t matter when.
● Choose to say “No”.
It’s easy to become overwhelmed if we say “yes” to everything. Think about the task before you commit to it. Do you need to do it? Can someone else do it? Avoid saying “yes” to every request.   40   
● Keep a goal journal
Write down your goals in a journal and evaluate them regularly. Mark your progress for each goal. Be sure you take the necessary step to achieve your goals.
A. Make a list first
B. Don’t skip the breaks
C. Turn that notification off
D. Memory is not always accurate
E. Don’t forget to focus on your task
F. This takes time away from more important tasks
G. Every time we switch from one task to another, we lose focus
