大一英语期末考试试题精选 又到一个学期的期末了，大家复习好大学英语了吗?为大家精心挑选了一份大学英语第一学期期末试卷，供大家复习使用，希望能够帮助到大家! 大学一年级英语试卷 Part II Reading Comprehension (30 %) Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheetwith a single line through the center. Passage One Science is not a set of unquestionable results but a way of understanding the world around us. Its real work is slow. The scientific method , as many of us learned in school, is a gradual process that begins with a purpose or problem or question to be answered. It includes a list of materials, a procedure to follow, a set of observations to make and, finally, conclusions to reach. In medicine, when a new drug is proposed that might cure or control a disease, it is first tested on a large random group of people, and their reactions are then compared with those of another random group not given the drug. All reactions in both groups are carefully recorded and compared, and the drug is evaluated. All of this takes time and patience. It’s the result of course, that makes the best news—not the years of quiet work that characterize the bulk of scientific inquiry. After an experiment is concluded or an observation is made, the result continues to be examined critically. When it is submitted for publication, it goes to a group of the scientist’s colleagues, w ho review the work. Einstein was right when he said: “No amount of experimentation can ever prove me right, a single experiment can at any time prove me wrong.”

As President Clinton said that day, the possibility that life existed on Mars billions of years ago was potentially one of the great discoveries of our time. After the excitement wore down and initial papers were published, other researchers began looking at samples from the same meteorite. Some concluded that the “evidence of life”was mostly contamination from Antarctic ice or that there was nothing organic at all in the rock. Was this a failure of science, as some news reports trumpeted? No! It was a good example of the scientific method working the way it is supposed to. Scientists spend years on research, announce their findings, and these findings
紧急通知 本资料由浙江大学控制科学与工程学院16届专业课129分学长，也就是我本人亲自整理编排而成。大家可以叫我学长，年龄比我大的辞职考的可以叫我小弟。资料不同于市面上那些看起来非常诱人实则是粗制烂造的资料，而是以一个考过845自控的过来人的经验，完全从学生的体验出发，做到资料最全，资料最好，资料最精致。全套资料包括葵花宝典一到葵花宝典九共九本资料，每本资料都是我精心编辑整理的，并做了精美的封面，一共650页完美打印发给大家，大家把这650从头到尾肯透了，再做下我推荐的几本资料书（16年有一道15分的大题就是上面的类似题，第三问很多高手都没做出来，注意不是周春晖那本哈），可以说完全没问题了。这是其它卖家不可能做到的。同时赠送845自控全套电子资料。葵花宝典一完全由我本人原创，里面包含了考浙大845自动控制原理的全部问题，比如考多少分比较保险，怎么复习，有哪些好的资料书，最近几年考题变化及应对策略，浙大常考题型，招生名额，复试资料，导师联系，公共课复习用书及方法以及845近年命题风格分析等一系列问题，全是我的心得和经验，方法，技巧等，说句心里话，我自己都觉得这些资料非常宝贵，能帮助学弟学妹们少走很多弯路。 注意：前面是一些关于我的故事，有些地方可能对你有用，如果不感兴趣，可以直接拉到后面去看，资料清单和图片都在后面。 学长自我介绍 学长姓邓，名某某，男，本科于14年毕业于四川大学电气信息学院自动化专业，考浙大控制考了3次，14年大三时第一次考浙大控制总分没过线。当时我们学校有三个同学征战浙大控制科学与工程，结果全军覆没，只有我一人过了300分，由此可见考浙大控制还是很有难度的，其中一个难点就是专业课的信息和专业课的命题走向的获取，当时我们都不是很清楚，蒙着头自己学，去图书馆借了很多自动控制原理的资料书来看，我自我感觉学得还不错，当时我一个同学考电子科大的自动化，经常跑来问我自控的问题，我基本都能给他解答出来，他说我好牛逼，觉对没有问题，然而最后的结果是他考电子科大自动控制原理137，而我只考了96分。后面我分析了一下，为什么会出现这样的情况？最重要的就是我们对浙大的出题风格不是很了解，不知道它的命题方向和爱考的地方，方向都错了，怎么可能得高分？虽然我把11年以前的真题都做了，但是浙大12年以后的命题风格和以前有所不同，所以还是无济于事。因此即使你的自控基础知识扎实，也未必能够得到高分，这里面有很多方法和技巧，都是我从后面的考试中慢慢总结出来的。 由于不甘心就这么与浙大失之交臂，所以决定二战，但是又不想向家里要钱了，因为学长家在贵州农村，经济条件不是很好。于是我选择平时晚上去给别人做家教，周末去给培训机构上课。这样的好处是我有大把的白天用来复习，只是晚上出去干干活。这个事就说到这里，不是主题。15年专业课考了113，一个中等的分数，本来可以考130，但是为什么没有考到，这些原因我都在葵花宝典一中给大家分析了，希望大家能我的身上汲取经验，别步我的后尘。但是15年死在英语不过线上，差3分，这是我怎么也没有想到的，学长英语虽然不能说特别好，但是最起码四六级大一就过了，高考英语还是我们小县城的单科第一名（山中无老虎），第一年也考了65分。这是我怎么也没有想到的，所以有的时候感觉

01 Passage 1 Hypnotism (催眠术) is very old. Thousands of years ago people started to use it in Egypt. The use of hypnotism has grown very much since that time. Today, doctors and scientists are in almost every country hypnotize people to help them with their problems. What is hypnotism, and how does it work? Many people think that a hypnotist puts people to sleep. Then he makes the hypnotized people do strange things. This is not what a hypnotist does. Hypnotism is really just a way to relax the mind and body. What are some of the uses of hypnotism? We go to a hypnotist because w e have a problem. The problem makes us unhappy. The hypnotist asks us to think hard about something and relax. When we are relaxed, t he hypnotist gives us some ideas to help us with our problems. Hypnotism can help people to remember things. The police sometimes ask hypnotists to help them. For example, a man sees an accident. He forgets the license number of the car he sees. If he is hypnotized he may remember it. The police can then find the car and catch the driver. People who are hypnotized can also make mistakes or say something that isn't true. People remember what they think they saw. That may not be what really happened. The police don't hypnotize people who do something wrong. Why not? People who are hypnotized may say something that isn't true. A person who has done something bad has a good reason to say something that isn't true. 1. Hypnotist helps people by ____. [A] putting them to sleep [B] helping them to get relaxed [C] offering his ideas about their problems [D] making them forget their problems 2. When hypnotized, some people may say something that is not true, because ____. [A] they do not remember what has happened [B] they remember what they think has happened [C] they do not know what has happened [D] they are not interested in what has happened 3. According to the passage, which of the following is TRUE?____ [A] Hypnotism is very different form what it used to be. [B] When a person is hypnotized, his body gets relaxed, while his mind works hard. [C] Hypnotism is much more widely used today than it was thousands of years ago. [D] When hypnotized, a person will do something strange. 4. The passage mainly talks about ____. [A] how hypnotism works [B] the development of hypnotism [C] the use of hypnotism [D] the wonder of hypnotism
