1．Miss Green isn'in the office．She _______ the library．（　　）

A．

has gone to

B．

went to

C．

has been to

D．

has come to

分析 Green小姐不在辦公室里，她去圖書館了．

解答答案：A．
英語中用have/has gone to表示去了某地，還沒回來．用have/has been to表示為"曾經去過某地"，現在已不在那里了，根據Miss Green isn'in the office，可知Green小姐不在辦公室里，應該是去某地了，所以用has gone to．故選A．

點評本題考查時態和語態．每個時態都有標志詞，熟記這些標志詞是做題的關鍵．在沒有時間狀語的情況下可以根據語境來對時態做出判斷．

10．If the only sports you do are dancing your fingers across your keyboard，you could be in serious danger of more than just becoming overweight and out of shape．
Do you often feel sleepy，like something is weighing down on your head？Do you feel forgetful？Do you sometimes feel uncomfortable up and down your neck and lower back，and you can't explain why？Do you get sick often？It could be radiation （輻射） from your computer causing it．If you spend three hours or more a day in front of a computer （and at this point，who doesn't？），you are more easily harmed by the hazards．
We have got so used to using computers that we often neglect （忽視） to think of them as dangerous sources of harmful radiation．A safe amount of radiation is 25V/m （Volts/meter）．Do you want to guess how much our personal computers give off？
Keyboard：1000V/m
Mouse：450V/m
Monitor：218V/m
CPU：170V/m
Notebook computers：2，500V/m
Ways of Protect Yourself from Harmful Computer Radiation
1．Decorate your desk with cactus （仙人掌） plants，they take in radiation．
2．Drink two to three cups of green tea a day and eat an orange daily．The vitamins in tea leaves and oranges protect us from radiation and keep our eyes healthy as well．
3．Use a screen filter（濾色鏡） for your monitor．
4．Avoid having metal objects （金屬物體） nearby on your desk．
5．Put the back of the computer to the wall．Most of the radiation comes off the back．
