根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

                                                          Well-done on an Exam

     Do not underestimate the power of revision in the days and hours before an examination. The closer you

are to the exam, the more chance you have of storing and attaining key information. But do not overdo it. 

1______ An effective daily routine can help you through an exam period, so in the days leading up to your

first exam, get into the habit of being up and read to work. It can be a shock to the system after months of

working to your own timetable to be mentally alert at that time if you have not prepared for it.

     On the day of the exam, have a good breakfast, pack everything you need ( pens, pencils, erasers, etc),

then make your way to the examination hall in good time. 2______ 

     Once in your seat, simply pause for a few seconds and collect your thoughts. Close your eyes and take

in a few slow, deep breaths to help you relax. When you turn over the test paper, spend a short period reading

through all the instructions and questions, paying particular attention to key verbs such as "discuss", "compare"

and "evaluate". 3______ It is always wise to allow 10 minutes at the end of the exam to give yourself time to

go back over your answers. Once you have selected the questions you wish to tackle, begin by attempting the

one you think is your strongest. It will give you more confidence when you see a well-answered question down

on paper. Also remember to write clearly, and do not be afraid to express the unexpected: after all, examiners

can get very bored marking stereotypical (模式化的) answers.

     4______ If you need something else to focus on to help you collect your thoughts, choose a fixture in the

room, such as the ceiling or anything else that will not allow you to be distracted.

     Finally, once you have finished, never hang around outside afterwards to attend the discussion by other

students. 5______ 

A. Try not to look at those around you, or at the clock.

B. When you get home, read the examination paper through and look up the other words you didn't understand. C. Sleep, exercise and relaxation are all just as important.

D. Map out a quick plan of points you wish to make and how much time you should spend on each question.

E. Go and have a well-earned rest---then prepare the next exam.

F. Do not arrive too early, though, as other people's anxiety can be contagious (传染性的), and you may suffer

    from undue panic.

G. If possible, you can arrive early and communicate with those worried students and help them overcome their

    anxiety.
