Aids today

  Aids is caused by a virus called HIV which enters a person’s blood and attacks the body’s immune system.There is no cure for HIV or Aids, and after a person has been infected, he or she will always carry the virus.Sometimes, infected people have no outward symptoms.

  HIV and Aids are spreading across the world at a frightening rate, with about 14,000 people being infected daily.The virus is spread in three ways-through unprotected sex, blood-blood contact and mother-to-child transmission.Unprotected sex is the most common way that the virus is spread, accounting for 75 percent of adult infections worldwide.

  Although many people are familiar with Aids and how it is transmitted, more than a few people hold the view that HIV and Aids are an African problem because the infection rates there are very high.However, HIV and Aids are a problem all over the world.Since the disease was discovered in the 1980s, it has become a serious problem in many places, infecting over 60 million people worldwide.According to the World Health Organization estimates from 2005, more than 4 million children had died from Aids, and more than 14 million children had lost their parents to Aids.All of this makes it clear that something must be done to stop this deadly disease.

  The government is working hard to control the Aids epidemic and has opened labs to test and monitor the disease.In 2003, the government also started providing free drugs for Aids patients in need.

  The United Nations has been very involved in fighting Aids and HIV around the world for many years now.UNAIDS, an organization founded in 1996 helps prevent the spread of Aids.The work includes providing infected people with help from doctors and testing for people.The organization also offers programs that teach Aids prevention to young people and sets up treatment centers.

阅读下列短文,从每题所给的四个选项(A、B、C、D)中,选出最佳选项。

  Besides this question of the time given to pronunciation,there are two other requirements for the teacher:the first,knowledge;the second,technique.

  It is important that the teacher should be in possession of the necessary information.This can generally be go form books.It is possible to get from books some idea of the speech;and of what we call general phonetic rules.It is also possible in this way to get a clear mental picture of the relationship between the sounds of different languages,between the speech habits of English people and those,of your students.Unless the teacher has such a picture,any explanations he makes on his students'pronunciation are unlikely to be of much use,and lesson time spent on Pronunciation may well be wasted.

  But it does not follow that you can teach pronunciation successfully as soon as you have read the necessary books.It depends,after that,what use you make of your knowledge;and this is a matter of technique.

  Now the first and most important part of a language teacher's technique is his own performance,his ability to show off the spoken language,in every detail of sound as well as in fluent speaking,so that the student's ability for imitation is given the fullest space and encouragement.The teacher,then,should be as perfect a model in this field as he can make himself.And to make his own performance better,however satisfactory this may be,the modern teacher has in his hand recordings and a radio,to supply the real voices of native speakers,or,if the teacher happens to be a native speaker himself,or speaks just like one,then to change the method of presenting the language material.

  However,the process of showing pronunciation,whether by personal ex-ample or with the help of machines,is only the beginning of teaching pronunciation.The technique of teaching each sound also needs to be considered.

1.How might the teacher find himself wasting lesson time?

[  ]

A.By spending lesson time on pronunciation.

B.Bu making ill-informed explanations upon pronunciation.

C.By not using books on phonetics in the classroom.

D.By not giving students a clear mental picture of the difference between

sounds.

2.Students have an ability for imitation which is________.

[  ]

A.plain and obvious

B.well developed

C.not yet developed

D.too weak to be useful

3.What is the main point the author makes about imitation of the teacher?

[  ]

A.It is a matter of secondary importance.

B.Students should be given every chance for it.

C.It depends on the student's ability.

D.Teachers are perfect models for students to imitate.

4.TO Someone teaching his own language to foreigners mechanical aids can________.

[  ]

A.improve his own performance

B.replace his own performance

C.provide examples of native speech

D.make his voice louder

5.Showing pronunciation is to be regarded as ________.

[  ]

A.a part of teaching pronunciation

B.an exercise of value in itself

C.an example of the use of mechanical aids

D.a technique for teaching separate sounds
