8．One Monday morning，Paul and his classmates were in science laboratory for their practical chemistry lesson．The students were going to work in pairs to do an experiment．Before they began，the teacher gave them this description of the different stages of the experiment．
Stage 1：Prepare the equipment：a test tube，a crucible，a Bunsen burner and tongs．
Stage 2：Weigh 5grams of baking soda （sodium bicarbonate） and put it in a crucible．
Stage 3：Heat 10ml of hydrochloric acid （盐酸） in a test tube．
Stage 4：Pour the warm acid onto the baking soda and continue to heat the mixture．
Result：The acid reacts with the bicarbonate（碳酸氢盐）to form water，carbon dioxide gas and salt．The hotter the mixture，the quicker the reaction．Continue to heat the mixture until the water evaporates，leaving the salt in the crucible．
Paul and his partner followed the instructions and set up their equipment．Paul went to the cupboard to get a bottle of hydrochloric acid．He found that there was only one bottle in the cupboard so he took that．There was no label on the bottle and Paul didn't check with the teacher if it was the right solution．
He measured the liquid and poured it into a test tube．Using tongs to hold the test tube，he heated it over the Bunsen burner．That's when things started to go wrong．The liquid in the test tube was not hydrochloric acid．When it was heated，it formed a thick cloud of white gas．Soon the room was full of this strong smelling white gas．
All the students started coughing and their eyes hurt．The teacher immediately opened the windows and ordered the students to leave the laboratory at once．She realized that the liquid was a crylamide （丙烯酰胺） and that it is poisonous．
Fortunately，nobody was injured in the incident．However，it taught the students and the teacher a good lesson．
43．What lesson did the incident teach the students and the teacher？A
A．Never have a bottle without a label in the chemistry lab!
B．Obey your teacher's instructions in the Chemistry lab．
C．Acrylamide can't take the place of hydrochloric acid．
D．Finding something unusual happened，you have to leave the laboratory at once．
44．What substance were the students making in the experiment？C
A．Water B．Carbon dioxide gas
C．Salt D．Poisonous gas
45．Why did Paul make the mistake？D
A．He went to the cupboard to get the bottle by himself．
B．He found that there was only one bottle in the cupboard so he took that．
C．There was no label on the bottle．
D．Paul didn't check with the teacher that it was the right solution．
46．Why did the teacher send the students out of the classroom？C
A．Because the room was full of this strong smelling white gas．
B．Because all the students started coughing and their eyes hurt．
C．Because the liquid was a crylamide and that it is poisonous．
D．Because someone was injured in the incident． 试题答案
分析 一天上午，Paul和同学们在科学实验室上化学实验课．同学们在老师的指导下分组进行实验．Paul误用了一个没有贴标签瓶子里的液体，结果出现了意外，丙烯酰胺反应后生成了有毒的气体．
解答 43．A．细节理解题．根据文章可知，同学们遵守老师的指导进行实验，排除B；Paul不知道瓶子里装的是crylamide，排除C；出现紧急情况时，要看情况的严重性再作出判断，排除D．实验出错的原因是Paul用了那个没有贴标签的瓶子里面的物质，故选A．
44．C．细节理解题．根据文章"The acid reacts with the bicarbonate（碳酸氢盐）to form water，carbon dioxide gas and salt…leaving the salt in the crucible"可知，同学们做实验要得到的物质是盐，故选C．
45．D．细节理解题．根据文章"there was only one bottle in the cupboard so he took that．There was no label on the bottle and Paul didn't check with the teacher if it was the right solution"可知，瓶子上没有贴标签，Paul没有和老师一起检查这个瓶子是否适合做实验用，故选D．
46．C．推理判断题．根据最后一段"She realized that the liquid was a crylamide （丙烯酰胺） and that it is poisonous．"可知，老师发现发生反应的是丙烯酰胺，而丙烯酰胺是有毒的，故选C．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
I am a writer. I spend a great deal of my time thinking about the power of language—the way it can evoke(唤起) an emotion, a visual image, a complex idea, or a simple truth. Language is the tool of my trade. And I use them all—all the Englishes I grew up with.
Born into a Chinese family that had recently arrived in California, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken” English. But I feel embarrassed to say that. It has always bothered me that I can think of no way to describe it other than “broken”, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness. I’ve heard other terms used, “limited English,” for example. But they seem just as bad, as if everything is limited, including people’s perceptions(认识)of the limited English speaker.
I know this for a fact, because when I was growing up, my mother’s “limited” English limited my perception of her. I was ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly her thoughts were imperfect. And I had plenty of evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.
I started writing fiction in 1985. And for reasons I won’t get into today, I began to write stories using all the Englishes I grew up with: the English she used with me, which for lack of a better term might be described as “broken”, and what I imagine to be her translation of her Chinese, her internal(内在的) language, and for that I sought to preserve the essence, but neither an English nor a Chinese structure. I wanted to catch what language ability tests can never show: her intention, her feelings, the rhythms of her speech and the nature of her thoughts.
