四阅读理解

Ⅰ For a clearer picture of what the student knows, most teachers use another kind of examination in addition to objective tests. They use “essay” tests , which

require students to write long answers to broad, general questions such as the following: “mention several ways in which benjamin franklin has influenced the thinking of people in his own country and in other parts of the world. ”

One advantage of the essay test is that it reduces the element of luck. The student cannot get a high score just by making a lucky guess. Another advantage is that it shows the examiner more about the student’s ability to put facts together into a meaningful whole. It should show how deeply he has thought about the subject. sometimes , though, essay tests have disadvantages, too. some students ate able to write rather good answers without really knowing much about the subject, while other students who actually know the material have trouble expressing their ideas in the essay form.

Besides, in an essay test the student’s score may depend upon the examiner’s feeling at the time of reading the answer. If he is feeling tired or bored, the student may receive a lower score than he should. Another examiner reading the same answer might give if a much higher mark.. because of this, the objective test gives each student a fairer chance, and of course it is easier and quicker to score.

Whether an objective test or an essay test is used , problems arise. When some objective questions are used along with some essay questions, however, a fairly clear picture of the student’s knowledge can usually be obtained.

1 what many have been discussed in the previous paragraphs? _________

[a]the essay test [b]how teachers test their students

[d]its scoring may be influenced by the examiner’s feelings

3 the word ‘this’ (line 4, para 3)refers to the fact that_________.

[a]students may receive a lower score in an essay test

[b]another examiner usually gives the answer a higher mark

[c]different examiners may give the same essay different scores

[d]the objective test gives each student a fairer chance

[b]it allows the student to guess the correct answer without really knowing the material.

Ⅱ Around the world two thirds of the people are farmers. Most of them engage in subsistence farming. This means that they raise plants and animals to furnish their families with food and other supplies. They consume their varied output and have little to sell or to trade for other goods. Subsistence farms were common in the united states at one time, but there are few such farms today.

Two thirds of American farmers practice commercial farming. Commercial farms produce about 97 percent of the country’s agricultural goods. these farms are operated much like other industries. The members of the farm family produce the commodities(商品) that will be sent to the market. they sell their products and buy the things they need.

Some commercial farms are big factories in the field. They may be owned by a company or by an individual as an investment. Most American farms, however, are still operated by families. a farmer may own or rent his land.

In a country as large as the united states, farms vary widely in climate, land surface, soil, water supply, convenience to market, and other characteristics. different regions may have different kinds of specialized farms. specialized farmers concentrate on the kind of farming best suited to the land and climate, to their technical skills , and to the money they invest in the farm.

However, no region is limited to a single type of farm. Indeed few farms are limited to one crop or commodity. where output is varied and no one kind of crop or commodity produces more than half of a farm’s income, it is classified as a general farm. the general farmer grows varied crops to use the different kinds of soils or surfaces on his land and to employ his time and machinery most efficiently.

ⅢIn the 1900’s, American townspeople usually washed and brushed their teeth and combed their hair in the kitchen. Or they kept a water pitcher(大水罐)and a wash basin in their rooms and took care of these things there.

The bathtub was a wash tub(澡盆)filled with water from the stove. If you were small enough you could sit down by drawing your knees to your chest. Otherwise, you washed yourself standing up. Often all the women and girls in the family bathed together. Then the men and boys did . In most families this was Saturday night because Sundays they went to church.

A small number of families did have running water .But that depended on whether there was a water system where they lived and on whether they could afford the plumbing(水管设施).Some people had bathtubs in their homes as early as 1895. But many others did not have their first bath in a bathtub until 1910 or later when they were fifteen or sixteen years old.

Passage two

CARIFF, Wales 桺oets , singers and musicians from across the globe gathered Wales to celebrate the tradition (传统)of storytelling.

“It might seem strange that people still want to listen to instead of watching television, but this is an unusual art form whose time has come again,” said David Amibrose ,director of Beyond the Border, an international storytelling festival(节) in Wales.

“Some of the tales, like those of the Inuit from Canada, are thousands years old. So our storytellers have come from distant lands to connect us with the distance of time.” He said early this month.

Two Inuit women, both in their mid 60s, are among the few remaining who can do Kntadjait , or throat singing, which has few words and much sound.

Their art is governed by the cold of their surroundings, forcing them to say little but listen attentively.

Ambrose started the festival in 1993,after several years of working with those reviving(coming back into use or existence)storytelling in Wales.

“It came out of a group of people who wanted to reconnect with traditions and as all the Welsh are storytellers, it was in good hands here.” Ambrose said.

First, they gave an intelligence test to the entire student body at an unnamed elementary school in the San Francisco area .Then , they selected students at random and told their teachers that the students’ tests had shown that they were about to experience a period of rapid learning. Teachers did not change their methods or materials for teaching the designated students, but at the end of the year, when the test was administered again, first and second graders who had been selected had , in fact, gained twice as many I.Q. points as the other children.

[d] that the I.Q. test used in San Francisco schools should be changed. Passage 2

You should see Manuel when he works on a car down at his father’s garage. He picks out a wrench or a screwdriver the way an artist would choose a brush to use on his masterpiece. He turns the tool over carefully in his hands, assuring himself that it’s the right size and type of tool for the job at hand. He is also as particular with his tools as an artist might be with his brushes. Manuel will not use a rusty or broken wrench; when he finishes a job , he protects the tool with a slight film of oil and replaces it on his shelves , carefully arranging his tools so that he can easily and quickly find the tool he wants . When he has finally selected the tool he needs .Manuel moves to the ailing car confidently like a surgeon in an operating room. He is quiet , he carefully touches the engine with his delicate hands. He may reach into the car’s inner recesses and move a lever or connection testing its tension, its range of movement, or its lubrication and adjustmen. Once he has made the diagnosis, he arranges his tools like scalpels and clamps in a tray.

自考英语语法名词解释

Acronyms Acronyms is a word coined by putting together the initial letters of a group of words. Affixation A word formation approach that attaches morpheme – an affix to a base,which is a word with 1 or more affixes in it. Anaphoric reference前照应A demonstrative determiner with anaphoric reference is more likely to go with a non-restrictive relative clause Cataphoric reference 后照应A demonstrative determiner with cataphoric reference,which goes with a restrictive relative clause Collective nouns These are generally countable nouns,but even in the singular they refer to groups of people,animals or things. Compound A compound,the product of composition,and it is a lexical unit consisting of more than one base and functioning both grammatically and semantically as a single word. Conversion The derivational process whereby an item is adapted or converted to a new word class without the addition of an affix. Coordination并列词Realized by coordinators (also termed coordinating conjunctions)which join units at the same level. Countable nouns Nouns that can take plural. Dangling participle:When the subject of participle is not expressed, it is normally to be the subject of the clause. It is usually poor grammar, and sometimes absurd, if this rule is broken: Trying to be quiet, the floor board creaked. But the rule is often broken when the subject is vaguely understood to be “one”, “we”, “you”, people in general. Determiner Words used in the premodification of noun phrase and put before any adjectives that premodify the head word of noun. Dynamic adjectives Many adjectives can also be used in the dynamic sense (be being a.)in predicative position to show subjective measurement or suggest a temporary state,implying the qualities can be controlled or restricted. (e.g. he is being rude) end-focus 尾部焦点under neutral conditions,the nucleus falls on the last element of the sequence as it is common that we process the information in a message to achieve a linear presentation form low to high information value. We refer to this as the principle of end-focus. ellipsis:省略leaves out the redundant/wordy part and do not provide a substitute. Exclamation Express our impression,especially our surprise,excitement,amazement,etc. It doesn…t take S-V inversion.

自考英语语法

本次语法串讲分三个部分,第一,方法篇;第二,命题特点分析;第三,重点章节复习。 第一、方法篇 自学考试英语专业《英语语法》科目是一门理论性和实践性都非常强的课程,旨在考核考生能否熟练掌握现代英语语法的基本理论和概念,掌握词的形态变化和用词造句的规则,以及组句成篇的一般形式和规律。 由于存在着英汉语言体系上的差异、教材的全英版和术语的生僻、语法本身乏味枯燥等外部因素,以及考生英语基础知识薄弱、精读和泛读的阅读数量尚未达到一定量因此不能将一些语法规则变成感性认识加以推演和归纳、甚至还有同学有畏难情绪,一旦跟不上就放弃,或者偷懒,不愿多做一些练习和多记一些概念解释,结果仅以一、二分之差没有及格,令人扼腕。 但是有志者事竟成,这句名言还没有过时。我们举几个成功的例子吧。 我教过的学生中有人刻意让自己爱上语法,首先,她克服困难,把全书通读一遍,可是有那么多不懂的单词和术语怎么办?她问我。我说,把它们暂时放在一边,然后通过例句猜测该词的含义,结果既记住了概念又结合了例句,相辅相成,直到掌握。 比如:什么是extraposition?这个词是由extra-(在……之外,额外)加position(位置),联想到appositive phrase(同位短语),appositive clause (同位语分句)等,那么从该词的外形上可以判定extraposition是“位置放在外围”。 它出现在我们教材中的《信息结构和强调》一章中,我们知道,突出强调信息的几种主要方法(postponement, fronting,inversion, cleaving,existential sentence)之一的后移又有三种后移的方法:passive voice, extraposition and discontinuity。从课本上我们看到这样的例句:To make fun of a disabled man is not funny at all. It is not funny at all to make fun of a disabled man. He found it annoying that his neighbor kept calling him by the wrong name. 你注意到这里有it出现在句中做形式主语和形式宾语,真正的主语和宾语在句末,然后,结合解释“When we re move a clausal subject or object to the final focal position, we use the anticipatory it to fill in the slot. Grammatically speaking, it is the formal subject or object while the extraposed clause is the real or notional subject or object. In function, the extraposed item can be subject or object; in form it can be finite or non-finite. 后移的结果就是满足了末尾重心(end-weight)的原则,达到强调的效果。
