Automobiles have, since their invention, revolutionized transportation, changing forever the way people live, travel, and do business. On the other hand, they have brought hazards, especially highway fatalities. However, today the application of computer 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.

3.Many products for sale seem to scream at us, "Buy me! Buy me!" Advertising is a big busin ess in our world with many products competing for our attention. Think of the last time you boug ht clothes. You probably noticed the variety of colors, patterns, fabrics and brands you could choo se from. Which kind of soft drink would you like to have today or what kind of computer do you want? Advertisers are skilled in the art of making their products look the best to appeal to our se nses. But products aren't always what they seem. Sometimes advertising is deceptive and as cons umers ,we must be careful about what we choose to buy. It is important to learn to compare prod ucts and identify our purpose in purchasing the things we need. But the good thing about advertising is that it helps people to make decisions and refine thei r choices. In the United States, the Ad Council creates timely public service messages to the nation. Th eir purpose is to raise awareness of public problems that citizens can respond to. Inspiring ads ca use individuals to take action and even save lives. Pollution in America, for example has been red uced over the years because of the creative Public Service advertisements that the council provid es" Please, please don't be a litter bug, 'cause every 'litter bit' hurts." Many families have taught t heir children to place litter in the trash can in response to this catchy phrase, which has affected g enerations as each succeeding generation has taught their children not to litter. 4.Nature imposes difficult conditions upon the earth from time to time . The tornado and fo rest fire destroy natural resources ,homes and other structures ,and very often harm or kill peopl e . Technological tragedies happen with little or no warning as we see trains crash and airplanes f all from the sky shortly after take-off. As tragic as calamities are , they seem to bring out the best in human nature . people trained in em ergency care arrive at the scene and begin assisting the inj ured .Others come with equipment to remove debris. Men , women ,and young people willingly c ome to the scene of an accident , hoping to be of help in some way . These selfless acts of kindne ss make our world a better place . compassion eases the wounds of calamities. American Airlines flight number 587 crashed less than three minutes after taking off from JF K Airport in New York in November,2001. Witnesses s aw an engine fire develop on the plane’s nu mber one engine located under the left wing of the aircraft .seconds later ,the airliner crashed int o eight homes ,completely destroying four of them .All 260 people aboard the airplane were kille d along with six people at the crash site ,leaving many people to mourn the loss of their loved on es .the residents (people who live in the area of the crash ) rallied together to comfort those griev ing, while others removed bodies from the wreckage and did the necessary clean-up. 工程实施困难的条件下在地上的时候。龙卷风和森林火灾破坏自然资源,房屋和其他建筑物,和经常伤害或杀死人。技术的悲剧发生在很少或没有预警,因为我们看到火车事故,飞机起飞后不久就从天空坠落。一样悲惨的灾难,他们似乎显示出人性中最好的。在急诊受训的人到达现场并开始帮助受伤的人则跟设备清除残骸。男人,女人,和年轻人自愿来到事故现场,希望能有帮助。这些无私的善举让我们的世界变得更美好。同情减轻灾害的伤口。 美国航空公司587号航班坠毁不到三分钟后从纽约肯尼迪机场起飞,11月2001。目击者看到一个引擎火灾发展在飞机上的1号引擎位于下飞机的左翼,接着后,客机坠毁八家,完全摧毁了四个260名乘客的飞机遇难连同6人在事故现场,造成许多人悼念失去的亲人,居民(住在崩溃的面积)聚集在一起,安慰那些悲伤,而另一些人则从残骸,并把尸体移走必要的清理。 5.Success can be reached in different ways by people in different careers. Bill Gates began at age to program computers,His vision for personal computing has been central to the success of M icrosoft Corporation, the company he founded with his childhood friend in 1975 . The former CEO of General Electric, Jack Welch, is a business legend. A famous quote by Mr. Welch is,” Chang before you have to. ”He believes in leading by example and encourages his empl oyees to do their best every day. Michael Jordan s aid,”I accept failure, but I can’t accept not trying.” He is one of the best athl etes to ever play team sports. His great smile, athletic achievements, and pleasant personality ha ve made him one of the most famous athletes in the world. Michael Jordan spent a lot of time pla ying basketball as a child but in senior middle school he was taken off the team . Instead of giving up , he worked through adversity and became the greatest basketball player yet .

In this way the author achieves coherence of text. 3.Students Analysis The class is made up of 56 students, with 30 girls and 26 boys ,who have a good knowledge of Basic English, but know very little about the American culture behind the language.
