　　advantages and disadvantages of private tutoring
　　nowadays， private tutoring is popular around us．a recent investigation shows that about 80％of pupils have private tutors．like everything else，private tutoring has both favorable and unfavorable aspects．generally，the advantages can be listed as follows．
　　first，private tutoring is usually one-to- one，the teacher knows the strong points as well as the weak points of the students；and teaching is ，in most cases，directly to the point．private tutoring benefits a lot of pupils，indeed．
　　but every coin has two sides．the negative aspects are also apparent．to begin with，it takes up so much of the pupils’ time that they can hardly find enough time for rest and entertainment，which are essential for their physical and mental health．besides，some teachers，busy“shuttling”from one family to another，tend to neglect their regular teaching duties．most important of all，some teachers are eager to help pupils do well on the test，offering the so-called tips for test—taking rather than help them acquire what is most needed．
　　through the above analysis，i believe that the disadvantages outweigh the advantages．greater emphasis should be laid on classroom teaching and practice，on the improvement of teaching quality and on the tapping of the pupils’ potentialities．only in this way can a new generation be healthily brought up．

　　should it be necessary to enlarge the private car market? why or why not?
　　nowadays，enjoying the luxury of owning a private car is popular around us．a recent investigation shows that about 80％ people desire to have private car．like everything else，having a car has both favorable and unfavorable aspects．generally，the advantages can be listed as follows．
　　first，having a car of your own means no more traveling to work on crowded buses or subway trains, and you can drop off the children at school on the way. moreover, it also means that you can enjoy the weekends and holidays better, because with a car you can go to places where the regular buses and trains do not go, and so you can find a quiet scenic spot with no crowds.
　　but every coin has two sides ( however, there are drawbacks to owning a car)．the negative aspects are also apparent ( for one thing )．to begin with，the roads are becoming more and more crowded because the increase in car ownership in recent years. it makes the journey to work like a nightmare. besides ( for another )，it is not cheap to run a car, as the prices of gasoline and repairs are constantly rising, not to mention the prices you have to pay for a license (办牌照) and insurance coverage (保险费). most important of all，driving a car means risk life if car accident happens.
　　through the above analysis，i believe that the advantages outweigh the disadvantages ( i have come to the conclusion the advantages of owning a car outweigh the disadvantages)．greater emphasis should be laid on how to regulate the private car driving. it seems to me that that china should increase its output of automobiles and enlarge the private car market. the result would be that cars would become cheaper, while at the same time the extra demand would encourage the auto industry to produce more efficient and family-oriented vehicles.

　　should it be necessary to study at home? why or why not?
　　nowadays，studying at home using such technology as computers is popular around us．a recent investigation shows that about 40％ people desire to study at home．like everything else，studying at home has both favorable and unfavorable aspects．generally，the advantages can be listed as follows．
　　first，as advances in the electronic media have brought the whole world of scholarship into the home via the internet and educational courses on tv, the classroom is no longer the only place for acquiring knowledge. moreover (second), a person studies better in the familiar surroundings of his own home and when he can arrange his own study time. in addition, studying at home would save you a lot of time.
　　but every coin has two sides ( however, there are drawbacks to studying at home)．the negative aspects are also apparent ( for one thing )．to begin with，it is difficult for some people to concentrate on study in the midst of disturbances from visitors and telephone calls. besides ( for another )，studying alone at home is boring for many people. most important of all，there can be no substitute for a good teacher, who must not only be able to impart facts and theories, but also to appraise and encourage his students.
　　through the above analysis，i believe that the disadvantages outweigh the advantages ( i have come to the conclusion the disadvantages of studying at home outweigh the advantages)．greater emphasis should be laid on how to adapt to personal studying habits.
