I would just be standing there. “I can’t see anything,” I would say. He would begin patiently enough, explaining how anybody can see through a microscope, but he would always end up in a fury, claiming that I could too see through a microscope but just pretend that I couldn’t. “It takes away from the beauty of flowered anyway,” I used to tell him.

例1
I passed all the other courses that I took at my University, but I could never pass botany. This was because all botany students had to spend several hours a week in a laboratory looking through a microscope at plant cells, and I could never see through a microscope. I never once saw a cell through a microscope. This used to enrage my instructor. He would wander around the laboratory pleased with the progress all the students were making in drawing the involved and, so I am told, interesting structure of flower cells, until he came to me.
例2
Home Computers
In recent years computers have entered more and more families in China. Many people find that computer have brought them with great convenience and enjoyment. It is true that a home with a good computer may function like a library, a mini-school, a post-office, an office and a place for entertainment.
一、句子的运用
根据新大纲的要求, 四、六级作文的字数为120词 至150词。按平均每个句子7～8个词计算，一篇作文 约十几个句子。而不少考生往往就是这十几个句子出 问题。有些作文虽内容较丰富，却因为句式表达失误， 结果让人越读越糊涂。有的因为随意乱打标点符号， 叫人看半天也不知句子应从就怎么写, 你明 不明白我不管。其实, 阅卷人最怕的就是一串莫测高 深的句子。一般来说,一篇作文只要不走题, 句子基本 通顺, 即可得10分左右。反之，则只有6分或低于6分。 这是我们不得不认真对待的。
“ We are not concerned with beauty in this course,” he would say. “We are concerned solely with what I may call the mechanics of flowers.” “Well” I’d say, “I can’t see anything.” “Try it just once again,” he’d say, and I would put my eyes to the microscope and see nothing at all, except now and then a nebulous milky substance---a phenomenon of maladjustment. You were supposed to see some vivid, restless clockwork of sharply defined plant cells, “I see what looks like a lot of milk,” I would tell him. This, he claimed, was the result of my not having adjusted the microscope properly, so he would readjust it for me, or rather, for himself. And I would look again and see milk.
