     Feb.3,2006-According to CCTV 4,Chinese scientists have recently taken the lead in building the first

full super-conducting experimental nuclear fusion (核聚变) device known  as"artificial sun"in the world,

which will produce energy like the sun.

    It is reported that this device consists of five layers of components(成分)from inside to outside and the

circulating magnet container in the innermost layer looks like a giant" swim ring". In experimental tests,the

temperature of inner" swim ring" will reach as high as 100 million degrees Celsius. Therefore,such

component is a significant part to stimulate solar fusion reactions.

    Wan Yuanxi,who is in charge of the project called Experimental Advanced Super-conducting

Tokamak( EAST) ,an important scientific project under China's ninth five-ycar plan,explained the reason

why the sun always gives off light and why the energy it produces will not decrease. Under high pressure

and high temperature, fusion reactions will take place from inside to outside of the sun.

     Such fusion reactions will give rise to a great deal of energy to enable the sun to continuously emit light

and heat. However,fusion reactions on the sun are uncontrollable,just like an H-bomb explosion seen on

the earth. A huge amount of energy will be produced in a minute,which may be destructive. In order to

make use of such energy,a transformation from the process of energy production to a stable,sustainable

and controllable process is needed. EAST is serving to initiate such a transformation. Under magnetic

force,the op-

eration of hydrogen plasma isotope (同位素) will be restrained in the" swim ring" and high density

collision will happen, namely the fusion reactions. The hydrogen isotope got from one liter of seawater

can produce energy equal to 300 liters of gasoline through complete fusion reactions.

    Wan said that we can get endless clean energy by producing such a device for accomplishing fusion

reactions,which is equal to one or a few small suns made by human beings themselves so that they can

ceaselessly obtain energy from nuclear fusions.

In our society, we must communicate with other people. A great deal of communicating is performed on a person-to-person (1) by the simple means of speech. If we travel in buses, stand in football match (2) , we are likely to have conversations (3) we give information or opinions, and sometimes have our views (4) by other members of society.

Face-to-face contact is (5) the only form of communication, and during the last two hundred years the (6) of mass communication has become one of the dominating factors of contemporary society. Two things, (7) others, have caused the enormous growth of the communication industry. Firstly, inventiveness has (8) advances in printing, photography and so on. Secondly, speed has revolutionized the (9) and reception of communications so that local news often (10) a back seat to national news.

No longer is the possession of information (11) to a privileged minority. Forty years ago people used to (12) to the cinema, but now far more people sit at home and turn on the TV to watch a program that (13) into millions of houses. Communication is no longer merely concerned (14) the transmission of information. The modern communications industry influences the way people live in society and broadens their horizons by allowing (15) to information, education and entertainment. The printing, broadcasting and advertising industries are all (16) with informing, educating and entertaining. (17) a great deal of the material communicated by the mass media is very valuable to the individual and to the society (18) which he is a part, the vast modern network of communications is (19) to abuse. However, the mass media are with us for better, for worse, and there is no turning (20) .
