Directions：Reform of English Education
Reform of English Education
As college English education is greatly emphasized with the rapid development of global commuiiicaticm，tbe defects that exist in the current educational system are open to more criticism- It is widely acknowledged that a thorough reform of college English education should be under way.
People ask for English education reform mainly because of the Inadequacy of college English education under the current system. On the one hand, many coilege English teachers underestimate the role interest plays in English learning and keep preaching in class. On the other h^nd, under the current system, most Chinese students tend to separate vocabulary memorizing, grammar, Hsteniiig, speaking, reading, and writing ftom each other and therefore their English is also “broken” in this way. This has also greatly contributed to the “dumb English” of many Chinese students.
In my view, to reform English education, colleges and universities should encourage students to speak English in class and hold more activities to promote students' oral English. Teachers should focus on attracting students with vivid teaching and arouse students* enthusiasm in learning English. With the collaboration, the reform of college BngHsh education will surely yield pleatifu] fitiits.
Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's flight one of the scientists wrote in his book, 'Look here for probable metal' Scientists in another airplane, flying over a mountain region, sent a message to other scientists on the ground,'Gold possible.' Walking across hilly ground, four scientists reported,'This ground should be searched for metals.' From an airplane over a hilly wasteland a scientist sent back by radio one word,'Uranium'.
None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of location minerals in the ground - using trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing.
This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxed were filled with small banches from te trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.
Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.
If the trees had not indicated that there was gold in the ground, the scientists would not have spent money to pay for digging into the deeper. They did dig and found more fold below. They dug deeper. They found large quantities of gold.
1. Scientists were flying over a desert or hilly wasteland or a mountain region in order to search for ________ in the ground.
2. The study of trees, branches and roots indicates that ________.
a. there were larger amounts of gold in the branches than in the seeds.
b. there were small amounts of gold in the roots than in the branches
c. there were larger amounts of gold in the seeds growing nearest to the tree trunk than seeds growing on the ends of branches.
d. there were more gold in the branches than in the roots
3. Which is the best title?
a. Scientists searching for metals with sepcial power
b. New methods of searching for minerals
c. Gold could be found by trees and plants
d. A new method of searching for minerals - using trees and plants
4. Which of the following is not mentioned as part of a tree that can help find minerals?
5. The scientists were searching for minerals by using ________.
b. magic power
c. a special instrument
d. trained eyes
In the United States, it is not customary to telephone somenone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p. m.. If someone receives a call during sleeping hours, he assumes it's a matter of life or death. The time chosen for the call communicates its importance.
In social life, time plays a very important part. In the U. S. A. guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of thime differs in different parts of the world. Thus, misunderstandings arise between peopel from cultures that treat time differently. Promptness is valued highly in American life, for edample. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U. S. no noe would think of keeping a business associate waiting for an hour, it would be too impolite. A person who is 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.

Liberia, the oldest independent Negro state in West A frica, has been struggling for survial ever since its foundation in 1822. Progress has been hampered by constant hostility between the American Negroes whose families returned there in the early 19th century, and the West Africans whose ancestors never left the continent. Though the two groups are of the same race, they are divided by language and outlook and regard each other with deep suspicion creating a conflict which was not foreseen by Liberia's founders.
In addition, neighboring states, native tribel, disease, and poverty have made life dangerous and difficult. The government has tried desperately, through loans and a trickle of trade, to make ends meet. Anxiety about financial matters lessened somewhat when, in 1910, the United States accepted responsibility for Liberia's sruvival. However, not until Harvey Firestone, the American rubber king, decided that the United States must produce itsown rubber - with Liberia as the site of the rubber plantations - did liberia have much hope of paying its debts and balancing its budget.
The rubber industry, founded in the 1920's, and the activity that followed it brought both progerss and profit to Liberia. Before that time Liberia had no roads, no mechanical transport and no good port; its people had little education and few tools. Liberians feel that the country is being ruled by rubber. For this reason, the recent discovery of iron ore is important. Liberian leaders are trying to moderate the power of the ruvver industry and to estaglish the country's political and economic independence.
1. Liberia has been in idffculty since its independence mainly because ________.
a. the american negroes do not want to help the country.
b. there have been constant hostillity and suspicion between different tribes in the country.
c. there haven been constant hostility and suspicion between two groups of the same tride.
d. the goverment has adoped a wrong policy

b. the goverment has to lend money to others
c. the goverment doesn't have to borrow or lend money
d. the goverment has either to borrow or to lend money
3. The country's finance began to improve a bit in ________.
4. The Liberians's attitude on to improve a bit in ________.
a. a total agreement
b. a total disagreement
c. a hostility
d. not a total agreement
5. The best title for this passage is ________.
a. American Negroes in West Africa
b. liberia - a poor country
c. liberia and its development
d. liberia - a country with rich rubber and iron
The accuracy of cientific observations and calculations is always at the mercy of the scientist's timekeeping methods. For this reason, scientists are interested in devices that give promise of more precise timekeeping.
In their search for precision, scientists have turned to atomic clocks that depend on various vibrating atoms or molecules to supply their "ticking". This is possible because each kind of atom or molecule has its own characteristic rate of vibration. The nitrogen atom in ammonia, for example, vibrates or"ticks" 24 billion times a second.
One such atomic clock is so accurate that it will probaly lose no more than a second in 3000 years. It will be of great improtance in fields such as astronomical is a sesium atom that vibrates 9.2 billion times a second when heated to the temperature of boiling water.
An atomic clock that operates with an ammonia molecue may be used to check the accuracy of predictions based on Einstein's relativity theories, according to which a clock in motion and a clock at rest should keep time differently. Placed in an orbiting satellite moving at a speed of 18000 miles an hour, the clock could broadcast its time readings to a ground station, where they would be compared with the readings on a similar model. Whatever differences develop would be checked against the differences predicted.
1. Scientists expect that the atomic clocks will be ________.
a. more precise
b. absolutely accurate
c. more durable
2. The heart of the atomichron is ________.
a. acesium atom
b. an ammonia molecule
c. a nitrogen atom
d. a hydrogen
3. From theselection, we may assume that temperature changes ________.
a. affect only ammonia molecules
b. may affect the vibration rate of atoms
c. affect the speed at which atoms travel
d. do not affect atoms in any way
4. Identical atomic clocks may be used to check ________.
a. the effect of outer space on an atomic clock
b. the actual speed of an orbiting satelite
c. the accuacy of predictions based on theories of relativity
d. all of Einstein's theories
5. Implied but not stated: ________.
a. Precise timekeeping is essential in science
b. Scientists expect to disprove Einstein's relativity theories
c. Atomic clocks will be important in space flight
d. The rate of vibration of an atom never varies
China boasts a long history in bridge construction.With wood and stone as the major buildingmaterials, Chinese ancient bridges vary in forms andare highly distinct.Constructed in the Sui Dynasty, Anji Bridge, which is located in Zhao County, HebeiProvince, is the oldest existing bridge in China.Anji Bridge, also named Zhaozhou Bridge, is akey national protected cultural relic measuring a length of 50.82 meters and a width of 9meters.In the late years of the Qing Dynasty, Huanghe Iron Bridge in Lanzhou was completed,symbolizing that China's bridge construction stepped into an era of adopting steel andconcrete as the main materials for bridges.Now, bearing many world records, China standsamong world giants in bridge construction.
1.第二句中的“以……为主要建筑材料”可处理为状语，用介词短语with……as the major building materials表达，而“中国古代桥梁”宜译为“形式多样，极富特色”的主语，谓语部分“形式多样，极富特色”可处理为并列内容，用and连接，表达为vary in forms and are highly distinct.
2.第三句“中国现存最古老的桥梁…位于河北省赵县”的定语较多，可以拆译成两句。首先译出主要结构Anji Bridge is the bridge，“现存最古老的”有两个形容词，英语中的比较级或形容词通常在其他形容词之前，故译为oldest existing.“隋代建造的”可处理为过去分词短语constructed in the Sui Dynasty 或which引导的定语从句。
3.第四句的主干是“安济桥为国家重点保护的文物”，故把“又名赵州桥”处理为插入语also named…;将“桥长50.82米，桥宽9米”处理为伴随状态的状语，用分词短语measuring a length of…and a width of…译出。
4.倒数第二句中的“兰州黄河铁桥”与“建成”之间是被动关系，翻泽时需把“建成”译为被动式wascompleted.“标志着中国…”是结果，故可处理为状语，用现在分词短语symbolizing that…表达。定语“以钢铁和混凝土为主要材料的”较长，可处理为后置定语，用现在分词短语adopting…as the main materials 表达，也可用介词短语with…as the main materials翻译。
