问答题

1.目前,北京市已经发展到了1000万辆自行车,而税收情况却与之不符,据统计:1995纳税的自行车为511万辆。1996年为498万辆,1997年为432万辆1998由379万辆,1999为316万辆。据税务局的同志介绍2000年征收的困难程度依然很大,情况不容乐观。一辆自行车的税费只有4元钱。加上0.5元的工本费。2.80年代末至90年代初.有人大代表和政协委员提议,北京是自行车的王国,如果对百万辆自行车征税可增加一部分财政收人。经过研究:北京市于1991年恢复征收自行车税,税额就定为4元加0.5元工本费。这样,当北京人还不太了解税为何物时。却突然要面对这一个事实:要自行车就得每年从腰包里多掏4元钱,叫“自行车税”。3.据安体富教授(人民大学财政金融学院的院长,身兼中国税务学会理事、中国财政会副会长等多职)介绍,自行车税由来已久,早在改革开放之前就曾出现过,后来有一段时曾停征。4.多年过去了,税费没有帐,而征税额却逐年下降、征收难度越来越难。市地税局处长顾某说,谁都会算这笔账,自行车税全收上来也不过4000万元.但国家制定了法律法规就要执行,这涉及到国家法制的严肃性。5.网友们谈及此事,谁都认为明星收入高,交纳个人所得税是天经地义。也许他们一次就要交个几千几万元,甚至传出过某明星一次纳税几十万元新闻,但多数人都没有想过,自己身边的这4元税款,和明星们几十万元的税款并没有本质区别。交与不交的界限在对于国家法律严肃程度的认知。在别人逃税时指着报纸大骂的人们,不知自己的4元税交了没有。6.有人说:“每年都交,可是那些没交的呢,不是也没有查吗?”7.还有人 “税是年年收。这自行车成天丢谁来管没准儿刚交了税车就丢了,我损失不更大了!”一个小伙子倒是直率:“反正也没人查得着我。好几年了我就没交过。”8.还有不愿交税的其他原因:A因为以前交了税后被人撕去税牌;B因为家里没钱;C因为车不常骑;D因为交税太麻烦,没时间……9.据《中国经济时报》报道,中国社会调查事务所在北京进行了一项街头拦截式调查,结果显示,有46%的人对自行车纳税持否定态度,也有29%的人拒绝接受调查,只有26%的表示自己或为家人购买了税牌,但调查时发现,其中仅有32%的人在自行车上贴了税牌,10.如果让你为了交4元钱的自行车税而去排长队,你愿意吗?如果让5000名地税的员工全部上街查税牌,1000万辆车,得查多少天!地税局干部上街检查,既危险又影响交通,结果还不明显。地税局现在改为到各主要存车处检查车辆,追根溯源查车主。即使这样.车海茫茫,漏网之鱼仍为数不少。11.有地税局干部说,“电话费不交可以停机.水电费不交可以断水断电.可这自行车税不交,不准他骑车出门也做不到啊!”12.自行车税是个小税种,却最不好征,大多数的地税局干部都有这个共识。

     A good hearing memory will help your child do better in school. Your child' s hearing ability is normal.

Yet, he may seem to be very poor at remembering and understanding what he' s heard at school.

     Why should this be? It' s because he' s not using his heating ability to help him to remember and

understand what he' sheen taught. Some children get into the habit of learning and remembering things by

what they hear. They' ve got good hearing memories. Other children find it easier to learn and remember

things by what they see, They' ve got good seeing memories.

     Some children have equally good ability of both seeing and hearing in learning things. Others, less

fortunate, seem to have poor hearing ~d seeing memories. Most children, I' d say, unwillingly prefer one

method over the other for learning and remembering. But this favoring of one sense over the other is a bad

habit and deprives (剥夺) the child of the full use of his natural senses.

     Mrs Allen was clearly incredulous when I told her there was nothing wrong with her son' s hearing. "But

he never seems to really understand what he hears. That' s what his teachers tell me," she said.

     "My psychological examination of William shows he' s weak in his heating memory ~" I said,"but he has

perfectly normal intelligence and can learn in school."

     "Our family doctor examined William and he said the boy' s hearing was all right. So, that proves you' re

right on that point." Admitted Mrs Allen."So how can we help him? My husband and I will do anything you

say, Dr. Dursteln."

     "You can do a lot to improve William' s hearing memory, but it' 11 take time. You must be patient and

not expect results immediately." I cautioned (告戒).

      I suggested a detailed program for the parents to use at home. I told Mrs Allen to come back and see

me every two weeks so that I could guide her in any problem she had in using my program.
