18．We      on this project for four hours．Let's have a rest．（　�。�
A．are workingB．have been working
C．workedD．had worked

分析 句意：我們一直在做這個項目已4個小時．讓我們休息一下吧．

解答 答案B．句中時間狀語"for four hours"通常與現(xiàn)在完成時連用，排除A、C和D選項．分析語境"Let's have a rest"可知，我們一直在做工作，說明"work on the project"動作在過去就已經(jīng)開始，一直持續(xù)到現(xiàn)在，因此用現(xiàn)在完成進(jìn)行時，故選B．

點(diǎn)評 本題考查時態(tài)的用法．解答此類題目的關(guān)鍵是要讀懂句意，分析上下文的語境，判斷時態(tài)，鎖定答案．

3．At thirteen，I was diagnosed（診所） with  kind of attention disorder．It made school difficult for me．When everyone else in the class was focusing on tasks，I could not．
In my first literature class，Mrs．Smith asked us to read a story and then write on it，all within 45 minutes．I raised my hand right away and said，"Mrs．Smith，you see，the doctor said I have attention problems．I might not be able to do it．"
She glanced down at me through her glasses，"you are no different from your classmates，young man．"
I tried，but I didn't finish the reading when the bell rang．I had to take it home．
In the quietness of my bedroom，the story suddenly all became clear to me．It was about a blind person，Louis Braille．He lived in a time when the blind couldn't get much education．But Louis didn't give up．Instead，h invented a reading system of raised dots（點(diǎn)），which opened up a whole new world of knowledge to the blind．
Wasn't I the"blind"in my class，being made to learn like the"sighted"students？My thoughts spilled out and my pen started to dance．I completed the task within 40 minutes．Indeed，I was no different from others； Ijust needed a quieter place．If Louis could find his way out of his problems，why should I ever give up？
I didn't expect anything when I handled in my paper to Mrs．Smith，so it was quite a surprise when it came back to me the next day-with an"A"on it．At the bottom of the paper were these words："See what you can do when you keep trying？"
