in order to satisfy the desire, they may go so far as to abandon their sense of right and wrong. teens and young adults may feel forced to use drugs, or join gangs that encourage criminal behavior. mature adults may sometimes feel pressured to cover up illegal activity at the company where they work, or end up in debt because they are unable to hold back the desire to buy a house or car that they cant afford in an effort to “keep up with the joneses”.however, peer pressure is not always negative. a student whose friends are good at academics may be urged to study harder and get good grades. players on a sports team may feel driven to play harder in order to help the team win. this type of influence can also get a friend off drugs, or to help an adult take up a good habit or drop a bad one. study groups and class projects are examples of positive peer groups that encourage people to better themselves.schools try to teach kids about the dangers of negative peer pressure. they teach kids to stand up and be themselves, and encourage them to politely decline to do things that they believe are wrong. similarly, it can be helpful to encourage children to greet the beneficial influence of positive peer groups.what is peer pressure参考答案单项选择1.b考查强调句式。句意:到目前为止,还没有科学证据证明是什么导致了恐龙的死亡。这里强调了恐龙灭绝的原因,即what,因此这是一个特殊疑问句的强调句型,强调句式后面要跟that,故可排除c、d两项;另外,由于这个强调句是作介词about的宾语从句,因此要用陈述句语序,故b项正确。2.c考查名词性从句。of后缺宾语,且宾语从句缺主语,又有选择范围,所以用which。3.b考查状语从句。句意:在森林中,声音是远距离交流的最好方法,因为与光相比,它不会在传播过程中被树阻挡。故选择b项。4.c考查特殊句式。句意:相关权威部门肯定已经采取了更为严格的措施来确保来年的交通安全,是不是?是的,绝对是。此题考查的是反意疑问句,依据陈述部分所使用的时态可知反意疑问部分用完成时态,故 c 项正确。5.b句意:我猜想当emily描述这次事件时是在撒谎,因为我很了解她。本题考查名词性从句。suspect 后为宾语从句,从句结构和意义完整,而根据后面for引出的并列分句可知,说话人对emily撒谎这件事情是很肯定的,故选b项。6.d考查情景交际。a.why me为什么是我;b.what for为何目的;c.why bother 何苦;d.so what那又怎么样。句意:为什么不向你姐姐求助呢?她负责这个小组。那又怎么样?她总是建议我要依靠自己。根据句意可知答案为d。7.
