Electronic Teaching

The potential of closed-circuit television and other new electronic teaching tools is so great that it is fascinating to visualize " the school of tomorrow ".

Televised lessons will originate from a central building having perhaps four or five master studios. The lessons will be carried into classrooms all over a city, or even an entire country.

After a televised lesson has been given, the classroom teacher will take over for the all-important " follow-up" period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion.

The teacher in the classroom will have additional electronic tools. On the teacher's desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students' levels of ability. For instance, while the class as a whole studies history, each student will receive an individual history lesson, directed to his particular level of ability.

Should question arise, the students will be able to talk directly to the teacher on individual " intercoms " without disturbing the rest of the class. In this way, the teacher will be able to conduct as many as three classes at the same time.

With the rapid development of computer science, students will be aided with specially prepared multi-media software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teacher's and get the score instantly. They will get certificates or diplomas if they pass all the required examinations. Experts believe that this type of education will be very popular in the years ahead.

參考答案:

1.A 第二段第一個(gè)句子是問題的答案。語音識別芯片嵌入(built.in)信用卡，當(dāng)信用卡使用者輸入口令時(shí)，就會自動(dòng)被識別。

2.C 第四段告訴我們，工程師們還未完全達(dá)到他們的預(yù)想目標(biāo)(Theyarenotquitethereyet。參見“注釋”6)，也就是說，他們對這種信用卡還不滿意，原因是，盡管和普通信用卡在長度和寬度~NN，但是厚度卻有普通信用卡的三倍。因此，c是正確答案。

3.D 第七段告訴我們，this earlier technology cannot prevent fraudulent use of stolen cards.Thenewonecan.第八段第一句中的also說明，先前的語音信用卡也同樣有發(fā)聲系統(tǒng)，所以，B不是正確選項(xiàng)，C也不是正確選項(xiàng)，因?yàn)橄惹暗恼Z音信用卡也需要使用者輸入身份信息。惟一不同的新技術(shù)是使用語音識別系統(tǒng)，只有在該系統(tǒng)確認(rèn)121令是使用者本人發(fā)出的才繼續(xù)工作。所以，D是正確答案。

4.c 第八段的第二句告訴我們，小偷即使知道口令，要模仿信用卡主人的聲音是幾乎能的。

5.A B、C和D的內(nèi)容都是使用語音信用卡時(shí)要經(jīng)過的程序。Switching on the electronics to maximize the battery life與文中的意思不符，更不是信用卡使用者使用時(shí)的操作程序，所以，A是答案。
