A.x+y-2=0

B.y-1=0

C.x-y=0

D.x+3y-4=0

答案

答案:A

要使直线将圆形区域分成两部分的面积之差最大,通过观察图形,显然只需该直线与直线OP垂直即可,又已知P(1,1),则所求直线的斜率为-1,又该直线过点P(1,1),易求得该直线的方程为x+y-2=0.故选A.

第二节 读写任务(共1小题,满分25分)

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

Beijing is set to lift its12-year-old ban on fireworks for the traditional Spring Festival holidays, probably starting from next Chinese Lunar New Year in January 2006.

Zhou Jidong, director of the Legislative Affairs Office of the Beijing municipal government(市政府), told a press conference last Thursday that his office has completed the draft(草案) regulations on firework safety supervision.

Under the draft regulations , setting off fireworks will be allowed in the capital city’s eight downtown districts from the Eve of the Lunar New Year to Lantern Festival 15 days later. When the draft regulations were posted on the municipal government’s website for suggestions, local residents gave a total of 969 pieces of advice, with 70 per cent in favour of lifting the ban. Related surveys suggest local people who want to light fireworks during Spring Festival range from 50.4 per cent to 86.3 per cent.

In fact, the voice of opposition and criticism has never ended since the municipal government introduced the ban in 1993, considering pollution, noise, fire worries and personal injuries caused by letting off fireworks.

Opponents accused the government of introducing the ban only for the sake of facilitating its management role while disregarding the will of the people. Worse, they say, the ban threatened to break down the age—old traditions of celebrating Spring Festival among Chinese people.

Partly due to this endless objection, about 106 out of a total 282 Chinese cities that had followed Beijing’s lead in banning fireworks have already dropped the ban.
