our home was a complete zooa joyous zoo. not surprising, i never did make it back to college fulltime. but i never gave up on the dream either. i had only one choice: to find a way. that meant taking as few as one class each semester. the hardest part was feeling guilty about the time i spent away from the boys. they often wanted me to stay home with them. there certainly were times i wanted to quit, but i knew i should set an example for them to follow through the rest of their lives.in 2007, i graduated from the university of north carolina. it took me over 21 years to get my college degree!i am not special, just singleminded. it always struck me that when youre looking at a big challenge from the outside it looks huge, but when youre in the midst of it, it just seems normal. everything you want wont arrive in your life on one day. its a process. remember：little steps add up to big dreams.16. when the author went to howard university, her dream was to be_.aa writer ba teacherca judge da doctor17why did the author quit school in her second year of college?ashe wanted to study by herself.bshe fell in love and got married.cshe suffered from a serious illness.dshe decided to look after her grandma. 18what can we learn about the author from paragraphs 4 and 5?ashe was busy yet happy with her family life.bshe ignored her guilty feeling for her sons.cshe wanted to remain a fulltime housewife.dshe was too confused to make a correct choice.19what does the author mostly want to tell us in the last paragraph?afailure is the mother of success.blittle by little，one goes far.cevery coin has two sides.dwell begun，half done.20which of the following can best describe the author?acaring and determined.bhonest and responsible.cambitious and sensitive.dinnocent and singleminded.基础写作近年微博(microblog)在中国越来越流行。假设你是校报记者，请根据下列提示为校报写一篇介绍微博的英语短文。写作内容1非常方便，人们可以随时利用微博来表达心声，交流想法；2给人们提供了一种释放压力的方式；3与朋友分享心情，增进人与人之间的了解；4也有潜在的危险，有可能泄露个人隐私或其他重要信息；5综上所述，使用微博要谨慎。写作要求1只能用5个句子表达全部内容；2短文的开头已给出，不计入总句数。评分标准句子结构准确，信息内容完整，篇章连贯。microblog has become part of our life._课时作业(三十二).1.because因“这孩子躲在了床底下或柜子里”与“没有救出孩子”是因果关系， 引导原因状语从句，用because。2dead3a固定搭配：catch a glimpse of看见。4they指代他那个社区的children。5which引导定语从句并在从句中作with的宾语，先行词是the oxygen mask。6in表示“用”某种语言，用介词in。7other表示“另外的，别的”，作定语，用other。8saves/has saved指客观事实，可用一般现在时；也可理解为告知性演讲“已经挽救了”许多生命，因此，也可用现在完成时。9fortunately修饰后面的整个句子，作状语，用副词。10taught过去分词作定语；由by可知此处表示被动含义。.a文章向我们介绍了一种新型的机器人，它能在身体受损的情况下进行自我调节、自我修复。11c细节理解题。由第三段的can sense injury to itself and adapt可知，这台机器人能够自己发现问题，并进行自动修复。12d细节理解题。由该段的from the information it collects, the robot creates its own programs that allow it to adapt to different situations.可知，随后所举的例子就是为了说明其能够搜集信息、适应新的环境变化。13c词义猜测题。下文把这种类型的机器人比作starfish，并把它的性能和真正的starfish进行了比较：a real starfish is much better than our robot at recovering from injury，由此可以得出答案。14a细节理解题。用排除法。最后一段告诉我们，机器人不能和真的海星(starfish)一样长出新腿，故排除c；由最后一段前三句话可知：科学家正在寻找地方来试验这种机器人，也就是说还没有在海底使用，所以d项错误；由倒数第二段的最后一句话可以看出，这种机器人具有自我修复功能，即使是在一条腿受损的情况下，用三条腿也能走路，故b项错误。15b主旨大意题。文章向我们介绍了最近研发出来的一款智能机器人，其独特之处在于能够在部件损坏的情况下进行自我诊断、自我修复。由此可以看出b项最能概括全文。b作者为了照顾自己的奶奶(姥姥)，不得不放弃了继续在大学深造的机会。在忙碌的生活中，作者依然坚守着自己当初上大学的梦想，用21年的时间获得了大学学位。16c细节理解题。由第一段的aiming at a legal career and dreaming of sitting on a supreme court bench somewhere可以看出，作者当初上哈佛大学的目的是：学法律、当法官。由此可以确定答案。17d细节理解题。第二段告诉我们，作者的奶奶(姥姥)得了癌症，作者withdraw from college to care for her，即：退学照顾奶奶(姥姥)。18a推理判断题。
