Immediately Josh stopped the car，jumped out，seized the kid and pushed him up against a parked car.He shouted at the kid，“What was that all about and who are you? Just what the heck are you doing？！”Building up a head of steam，he went on，“Thats my new Jag，that brick you threw will cost you a lot of money.Why？”“Please，mister，please.Im sorry! I didnt know what else to do！”begged the youngster.“I threw the brick because no one else would stop！” Tears were streaming down the boys face as he pointed around the parked car.“Its my brother，mister，” he said.“He fell out of his wheelchair and I cant lift him up.” Sobbing，the boy asked the businessman，“Would you please help me get him back into his wheelchair? Hes hurt and hes too heavy for me.”Moved beyond words，the young businessman felt no anger.He lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts，checking to see that everything was OK.He then watched the younger brother push him down the sidewalk.It was a long walk back to the cara long and slow walk.Josh never did fix the side door of his Jaguar.He kept the dent(凹痕)to remind him not to go through life so fast that someone has to throw a brick at him to get his attention.Feel for the bricks of life coming at you.1The boy threw a brick at the businessmans car because _.Athe businessman drove at a high speedBhe envied the brandnew car very muchChe wanted to ask for some moneyDhe wanted to get help from the driver2Which of the following is the right order of the story?aThe younger brother threw a brick at Joshs car.bThe elder brother fell out of his wheelchair.cThe younger brother begged Josh for help.dJosh lifted the elder brother back into his wheelchair.eJosh shouted at the younger brother.Ab，a，e，c，d Ba，c，d，b，eCb，a，c，e，d Da，c，b，e，d3What can we learn about Josh?AJosh would accept the money from the kids.BThe two kids were Joshs neighbors.CJosh was a kindhearted man.DJoshs new car broke down easily.4John checked everything was OK _.Ain order to make sure the little boy wasnt lyingBin case that the boys should need more helpCso as to make clear the boys were poorDin an effort to prove the elder brother was hurt5By the last sentence the author wants to say that _.Atrying to get ready for the trouble in your future lifeBdriving fast in a neighborhood street is dangerousCtrying to be more considerate of others troublesDprotecting oneself from being hurtUnit 2Growing pains.1解析：本文是介绍头发的文章，如头发的结构，组成和生长周期等。答案：Our hair2解析：第三段是在介绍头发的结构，它由两部分组成：一部分是可以看见的shaft，另一部分是root部分。答案：Structure3解析：由第三段第二句可知，root是living part。答案：living part4解析：由第二段第一句可知，头发的平均数量是120 000。答案：120,000 strands5解析：由第二段第一句可知，每根头发的寿命是大约3年。答案：Life expectancy6解析：由第四段第三句话后部分可知，头发的生命周期是由三个阶段组成：第一阶段是一两个长而活跃的生长阶段，第二个阶段是非常短的过渡期，第三个阶段是休眠期。答案：Growth cycle7解析：由第四段第四句可知，第一个阶段是长而活跃时期，时长大约三年。答案：long a
