Automobiles have, since their invention, revolutionized transportation, changing forever the way people travel, and do business. On the other hand, they have brought hazards, especially highway fatalities. However, today the application of puter technology and electronic sensors in designing and manufacturing cars makes it possible to eliminate most of traffic accidents. For example, electronic sensors mounted in your car can detect alcohol vapor in the air and refuse to start up the engine. They can also monitor road conditions by receiving radio signals sent out from orbiting satellites and greatly reduce your chances of getting stuck in traffic jams.Text B Comprehension Check 2. a c c d b bTranslation 5. 這類系統(tǒng)易受氣候變化的影響， 提供的數(shù)據(jù)不夠精確，但他們不需要特別的道路設(shè)施，只需要將車道標(biāo)志維護好就行了。Unit 1 Text ALanguage Sense Enhancement1. the fierce resistance 2. the long march 3. the devastating enemy 4. bleak 5. launched 6. military might 7. mowed down 8. campaign 9. a painful lesson 10. the aid Language FocusVocabularyI.1. 1) alliance 2)at the cost of 3) stroke 4)limp 5)minus 6) regions 7) declaration 8) siege 9) raw 10) bide his time 11) have taken their toll 12) in the case of 2. 1) is faced with 2)get bogged down 3) is pressing on/pressed on 4) drag on 5) get by 6)dine out 7) have cut back 8) get through 3. 1) head to the conquest of cancer in the near future 2) has been brought to a halt by the delayed arrival of raw materials due to the dock worker’s strike 3) will/should never get in the way of her career 4) caught the foreign minister off guard 5) of the electronic calculator has rendered the slide rule out of date/obsolete4. 1) Being faced with/the occupation of/regions 2) crucial to/efficient/to reckon with/weaken/be brought to a halt 3) a heroic/the decisive/turned the tide/siege/by launchingII.
