英语阅读解析!
It was the last day of the final examination in a large eastern university.On the steps of one building,a group of students were talking about the exam that was going to begin in a few minutes .On their faces was confidence.This was their last exam—then on to graduation and jobs.
Some talked of jobs they already had,others talked of jobs they would get.With the certainty of four years of college,they felt ready and able to take control of the world.
The coming exam,they knew,would be an easy task,as the professor had said they could bring any books or notes they wanted,requesting only that they did not talk to each other during the test.
Happily they entered the classroom.The professor passed out the papers.And smiles appeared on the students’ faces as they found there were only five questions.
Three hours had passed before the professor began to collect papers.The students no longer looked confident.On their faces was a frightened expression.Papers in hand,no one spoke as the professor faced the class.
He looked at the worried faces before him,and then asked:“How many completed all five questions?" Not a hand was raised.
“How many answered four?” Still no hand.
“Three?Two?” The students moved restlessly in their seats.
“One,then?Certainly somebody finished one .” But the class remained silent.
The professor put down the papers.“That is exactly what I expected ,” he said.“I just want you to know that,although you have completed four years of study,there are still many things about the subject you don’t know.These questions you could not answer are relatively common in everyday practice.” Then,smiling,he added,“You will all pass this course,but remember—even though you are now college graduates,your education had just begun.”
Question：The students were confident because -----
A：the final examination would be very esay
B：they believed that they were ready foreverything
C：they could get good jobs after the exam
D：they were quite sure to pass the coming exam
可我不知道为什么b就不对,老师说是“everything”不对,与文中“they felt ready and able to take control of the world.是不一致的.但是我认为b选项与文中感情色彩是一致的.
英语好的朋友帮忙看看这篇文章吧,到底为什么啊?b错在哪里了?我认为是错在答非所问,而不是那个“everything”
而且现在总觉得老师的解释很模模糊糊,是我自己的原因么?英语阅读有没有什么准则啊~

我在高中也做过这篇英语阅读,很高兴再见到这篇阅读.谢谢.
首先,你问题上集中在B和D,那么,分析一下.
B说的是他们相信他们准备好了任何事.确实是,首先呢感觉B 符合文中的感情色彩,因为This was their last exam—then on to graduation and jobs.
Some talked of jobs they already had, others talked of jobs they would get. With the certainty of four years of college, they felt ready and able to take control of the world.
The coming exam, they knew, would be an easy task, as the professor had said they could bring any books or notes they wanted, requesting only that they did not talk to each other during the test.
但是,好好看了以后,你会了解到,其中,学生们不是准备好了任何事,文中只是说了他们已经大四了,有的有了工作,有的没有工作,反正这次考试后他们会走向社会.这是一点；
还有的是,这次考试,老师说你可以带书或者笔记,这让同学们感觉这次考试必然通过.这是他们的感觉.这是其二.
你们老师说的也对,everything这也太绝对了,在选项中太绝对的词一看就应该排除的.这是其三.
何况你可以理解,这篇文章只是说了这次考试,一次考试,开始他们很自信,因为他们认为很简单,经过考试后,他们发现很难,都不会做.然后老师就给他们一个lesson,一个教训.这才是本文的本质.你所说的那个也对,本质没有什么错,prepare for everything,也就是准备好了考试,B范围你自己感觉感觉,是不有点太大了.好好想想.
而且做题要选最恰当的选项,理解吗?
这是我的见解,希望你可以理解.好好加油学习英语奥~~
再问： 你做题有没有什么最主要的基本准则呢？很多时候我总是多想，错想，主旨大意和推理判断题的正确率很低。。。。 现在真的是感觉陷入困境了，不知道怎么办了。。。。
再答： 是的，我当时就有这个感觉。告诉你一个办法，那就是多查字典，弄清楚单词的准确意思，避免理解模糊，这个你应该理解；还有就是要抓住主旨，这个是非常重要的，在范围大的和范围小的选项之间徘徊时，一定要选范围小的，因为这个更贴近主旨。 其他什么暂时也没有什么了，遇到具体问题时可以继续找我奥~~It's my pleasure~~~
