英语翻译
Walter had been a good high school student but not an excellent one.He got almost all Bs and a few Cs.He had done his homework most of the time and once in a while he had skipped class（旷课）.When he got to Furnell,he didn’t change his study habits.As a result he got a bad grade on the first test in chemistry­-65 percent,or D.When the teaching assistant gave back his quiz,he also gave him some advice.
“Look,Walter,I know you’re having problems with this course”,Gordon told Walter,“Remember that the teacher requires attendance.In other courses it might be okay to skip class once in a while,but not in this one.A good grade in chemistry depends on attendance,good homework,and going to lab every week.If you continue to do the quiz poorly,you’re going to have problems.”
Walter thought about his advice a lot over the weekend.“The teaching assistant was serious.I'm doing poorly,and I might fail chemistry.In that case I would have to leave Furnell.I don't want to go home and find a job” From that weekend he started studying very hard.In addition,he started to do all his assignments and to go to lab every week.After a month,he was able to answer almost all the quiz questions correctly.
“I'm happy to see that you're doing better in this course” teaching assistant said to Walter.
“Yeah,me too.It's a challenge（挑战）to study every afternoon when I fell like playing football or video games.But now I know that chemistry is not an impossible course.”

沃尔特曾经是一个不错的高中生但并不是很杰出的那一类.他的成绩单上大多数是得到B和少数的C,他大多数的时间用来做他的家庭作业不过偶尔会旷课.当他到Furnell（这应该是所学校的名字）时,他并没有改变他的学习习惯,结果在他的第一次化学测验上他得到了糟糕的成绩,65分,D.当他的助教把他的考卷给他时,他给了沃尔特一些建议.
“看,沃尔特,我知道你在这么课程上遇到了一些麻烦”,戈登告诉沃尔特,“记着老师要求到场听课,在其他的课程中也许偶尔缺席一节或几节课没什么所谓,可是化学不是这样.想在化学上取得好成绩依赖的是出席,好的作业,以及每周都去实验室.如果你继续不认真的做测验,那你将会有麻烦了.”
周末沃尔特思考了很久助教的建议.“助教很严厉,我做不好,在化学上我也许会失败.这样的话我将要离开Fufnell.我不想就这样回家然后找份工作.”从那周之后他开始努力学习.除此之外,他开始做所有他的练习,每周还去实验室.一个月之后,他已经可以正确的答出几乎所有的测验问题了.
“我很高兴看到你在这方面做的更好了.”助教对沃尔特这么说.
“是的,我也一样.当我每天下午想要踢球或者玩游戏时去学习,这是个挑战.但现在我知道了,化学并不是一个不可能完成的课程.”
