【篇一：大学英语综合教程6 课后练习答案】

i first came into contact with online teaching,i had questions about the validity of this instructional medium.i would not know whether the student submitting the work was the same person who registered for the course.

online teaching also required rethinking how i deliver the subject matter,without face-to-face communication,can i,via computer,make the students feel the same kind of enthusiasm and appreciate my sense of humor?

my shy daughter’s experience proved to be very inspiring.she never spoke in class,but in the two online courses she took,she dived into discussions and posted her opinions.

the online course began and things ran better than i had expected.the students all followed the directions well,and the discussion board was lively.i’ve never met any of my students but i got to know them by their work and i saw their learning attitudes develop before my eyes.

i found that online education worked best with students who were very comfortable with the computer and willing to become part of a community built around the subject matter.and it required teachers to be willng to help build that sense of

community and make the students feel the teacher was always there.

刚接触网络教学时，我质疑过这种教学方式的有效性。我无从知道提交作业的学生和注册的学生是不是同一个人。

网络教学也要求我重新思考讲授课程内容的方式。没有了面对面的交流，只通过计算机，我还能使学生感受到同样的热情和幽默感吗？

一向腼腆的女儿给我很大启发。她从来不在课堂上发言，但是她报的两门网络课程上，她却全身心投入讨论，发表意见。

网络班开班了，情况比我预想的要好，学生都能很好的遵守指令，讨论版也很热闹。虽然我没见过任何一个学生，但我可以通过他们的功课来了解他们，看到他们的学习态度在我眼前慢慢形成。

我发现，对于那些电脑使用得心应手并且愿意融入围绕课程内容形成的团体之中的学生来说，这种学习的效果似乎更好。而老师需要愿意帮助建立起这种团体意思，让学生感觉到老师就在身边。 unit2

sloppy people are not really sloppy.it is just that the plan they carry in their mind’s eye is too precise,too stupendous and too perfect to be achieved in this world or the next.they aim too high and wide.they save everything ,planning someday to file and order.when they finally set about handling things,sloppy people just can’t bear to part with anything.after hours of

work,the place looks exactly the same.so sloppy people never get neat.

neat people place neatness above everything else.they like results and don’t care about process.they have cavalier

attitudes toward possessions.if anything collects dust,it’s got to go.they are incredibly wasteful.anything that is not of immediate use goes into the trash.they are insensitive and there is no sentimental salvaging of birthday cards or the last letter a dying relative ever wrote.neat people operate on two unvarying principles:never handle any item twice,and throw everything away.so the only thing messy in a neat person’s house is the trash can.

so neat people are lazier and meaner than sloppy people.the distinction between them is moral.

邋遢人其实不是真的邋遢，只是他们心目中的计划太周密，太宏伟，太完美，今生来世都无法实现。他们把目标定得太远太高。他们把东西都留起来，等有一天去处理、归档。终于着手清理时，又什么都舍不得扔。折腾了几个小时后，一切看上去还跟原来一模一样。所以邋遢的人永远整洁不起来。

整洁人把整洁放在至高无上的地位，只顾结果，不管过程。他们对财物漫不经心，只要会沾灰的东西就扔掉。他们挥霍起来令人难以置信，一时用不上的东西都丢进垃圾桶。他们麻木不仁，绝不会多凑善感地留着生日贺卡或某亲戚的临终绝笔。整洁的人有两条雷打不动的原则：任何东西绝不处理第二次；把东西都扔掉。所以整洁人家里唯一凌乱的就是垃圾箱。 由此可见整洁人比邋遢人懒惰、刻薄。他们之间的差别是品行层面的。 unit3

her daughter smoked and she felt a deep hurt as her

mother.she rememberd how as a child she sat by,through the years,and watched her father,who smoked like a

chimney,wheeze through most of his life feeling half his

strength,and she remembered how carefully she ate when she was pregnant,how patiently she taught her daughter how to cross a street safely.she had a feeling of futility when she saw her daughter repeating the mistake of her grandfather.

she did not want to see in the family another victory for the tobacco companies,but she was faced with powerful rivals.:the tobacco industry and hollywood.the too collaborated to win over completely people like her father and made them hopelessly addicted to cigarettes.

it is not easy to quit smoking,but things may become easier if smokers realize that smoking is a form of selfbattering that also batters those who must sit by,and if we can really make”every home a smoke-free zone”.

女儿抽烟，让当母亲的她觉得伤痛不已。她想起自己从小就一直看着烟瘾很重的父亲大半辈子有气无力地挣扎呼吸；也想起自己当年在孕期如何小心翼翼地饮食，又如何不厌其烦地教女儿过马路。而如今看到女儿在重蹈外公的覆辙，她有种无能为力的感觉。

她不愿意看到烟草公司在她家里取得另一场胜利，但她要面对的是非常强大的对手：烟草业和好莱坞电影。正是这二者联手，把像她父亲那样的人完完全全争取了过去，使她们无可救药的染上了烟瘾。 戒烟不容易，但如果吸烟者们意识到抽烟不仅是一种自我毁灭，而且也毁灭着那些不得不坐在他们身边的人。如果我们能真正做到“家家都是无烟区”，事情也许可以变得容易些。 unit4

marriage has always been difficult. why has it become so hard for couples to stay together in today’ society?

on the one hand, our modern social fabric is thin, and the permissiveness of society has created uealistic expectations and thrown the family into chaos. on the other hand, marriage requires sexual, financial and emotional discipline, but people today are unwilling to exercise the self-discipline that marriage requires. besides, couples today must also deal with all the cultural changes brought on in recent years by the women’s movement and sexual revolution. these and other realities of life erode the visions of marital bliss. if we lack adaptability, flexibility, genuine love and kindness, and an imagination strong enough to feel what the other is feeling, if we cannot bring difficulties out into the open, then marriage may come to the end of the road.

of course, divorce is not an evil act. for some people, it provides salvation and it can be a step toward a good life. however, marriage that do not fail but improve, that persist despite
