武汉到南京的动车共3趟,每趟运行时间约3.5小时。把动力装置分散安装在每节车厢上,使其既具有牵引动力,又可以载客,这样的客车车辆叫做动车。而动车组就是几节自带动力的车辆(动车)加几节不带动力的车辆(也叫拖车)编成一组,就是动车组,假设动车组运行过程中受到的阻力与其重力成正比,每节动车与拖车的质量都相等,每节动车的额定功率都相等。

(1)若1节动车加3节拖车编成的动车组的最大速度为120 km/h;则6节动车加3节拖车编成的动车组的量大速度为多少?

(2)若动车组在匀加速运动过程中,通过第一个50 m所用时间是10 s,通过第二个50 m所用时间是6s,则动车组的加速度为多少?

Young drivers are over-represented in alcohol--related driving accidents. In recent years, people aged 16 to 24 were involved in 28 percent of all alcohol--related driving accidents, although they make up only 14% of the U. S. population. Young people are also over--represented in drinking driver injuries and deaths. Even when their blood alcohol contents (BACs) are not high, young drinkers are involved in driving accidents at higher rates than older drivers with similar BACs.

Fortunately, driving accidents have been declining among young people, just as they have among the general population. And deaths associated with young drinking drivers (those 16 to 24 years of age) are down, having dropped 47% in a recent 15--year period.

In contrast to popular belief, drinking among young people is dropping and has been doing so for many years. For example, statistics demonstrate that within a period of about 20 years, the proportion of American high school seniors who have ever consumed alcohol is down 13%;the proportion of those who have consumed alcohol within the previous year is down 15%.

Exaggerating the degree of drinking problems of young people may create an unexpected problem. When young people go to college falsely believing that most others are drinking heavily, then they may try to follow suit. Thus, those who exaggerate the problem of alcohol abuse actually contribute to the problem and make it worse. However, when students find out that most others don’t drink as much as they incorrectly believed, they are very likely to drink less and even give up. So, honest accuracy rather than dishonest exaggeration is the most effective way to reduce alcohol abuse and the problems it causes.

A. in the U. S. people aged 16 to 24 caused half of the alcohol--related driving accidents

B. it’s a fact that young people are drinking more nowadays

C. the number of high school students in the U. S is dropping

62. The underlined phrase “follow suit” in the last paragraph means ____.

A. stop drinking
