布鲁塞尔的第一市民

       一进布鲁塞尔市的中心广场,你必定会看到一座十分有趣的雕像,那是一个(zhì chì)气可掬的小男孩。他高高地立在一个喷泉中央,提着小裤衩,叉开双腿,聚精会神地在(sā shǎ)尿,这根尿柱成了喷泉的小水柱。这个小男孩就是布鲁塞尔的第一市民。     

       为什么布鲁塞尔的第一市民既不是王公贵族,也不是功臣英雄,而是这个普通的小男孩呢?这事说来话长。     

       17世纪末,法国企图把布鲁塞尔纳入自己的统治之下。他们出动大批军队,向布鲁塞尔疯狂进攻,但每次都被英勇的布鲁塞尔人民击退。法军恼羞成怒,决定炸毁城墙。一天晚上,市民和将士们都呼呼大睡,沉入了梦乡。法军趁机(qián  tì)到城边,在城墙脚下安放炸药,点燃了导火线。在这千钧一发之际,一个家住城墙边的小男孩,被尿憋得急,从屋里跑出来,扯开裤子准备撒尿。突然,他看见墙脚下有一条亮闪闪的火花,还吱吱地响着,顺着火光看过去,竟是一大堆炸药。他急忙把尿撒在导火线上,等到火熄灭后,他马上跑回家叫醒睡着的大人们。大家从床上一跃而起,纷纷投入战斗。在全市人民和将士的英勇抗击下,法军被彻底击败了。     

       布鲁塞尔得救了,布鲁塞尔人民又一次保住了自己的家园。人们在兴高采烈之余,找出这个小男孩,把他连连抛向空中。     

       在全市人民的一致要求下,市长亲自授予这个小男孩“布鲁塞尔第一市民”的荣誉称号,并给他挂上了奖章,戴上了桂冠。之后,市长又下令(sù  suò)了这座十分精致、有趣的雕像,矗立在市中心广场上,以纪念这位小男孩的救城之举。 

1.给文中画线的字选择正确的读音。 

2.替下列词语找出近义词。

     英勇——(       ) 精致——(       ) 急忙——(       ) 矗立——(       )

3.照样子,用画线的词造句。    

     布鲁塞尔第一市民既不是王公贵族,也不是功臣英雄,而是这个普通的小男孩。

                                                                                                                                                   

4.读文填空。

       布鲁塞尔的第一市民是             。17世纪末,           军进攻              ,他们深夜潜到城边,在城墙脚下安放炸药,点燃了导火线。在这              的时刻,          把尿撒在                上,救了全城的居民。小男孩是个                    的孩子。

      Tens of thousands of Chinese have joined a debate on whether students should be separated into science

and liberal arts (文科) classes in high school, a practice that allows them to stay competitive (有竞争力的) in

college entrance exam by choosing preferred subjects. The debate came after the Ministry of Education began

to ask for opinions from the public on Friday on whether it was necessary and possible to stop the dividing

system, which has been accepted for decades.

      In a survey started by www. qq. com, more than 260 000 people cast their votes, with 54 percent of

those voted for the abolishment (废除) and 40 percent against.

       A netizen from Chengdu said:"Sciences can activate the mind, while arts could strengthen their learning

ability."

       But some people disagreed with him. A netizen nicknamed "gentle scholar" said the students would have

more burden if they have more subjects to study. "You don't even know how difficult the courses are. I

suggest a survey among students."

       "Abolish the current system of division? We have to study nine subjects? Finally we will study everything

and have learnt little," wrote another netizen.

       Li Yanling, an education expert in Beijing, called on education authorities to consider students' school

burden. Chinese students are required to choose either arts or sciences subjects after ten years' education,

which include six years in primary school, three years in junior high school and one year in senior high

school.

       Besides the Chinese language, mathematics and English, which are must for everyone, science students

are required to take physics, biology and chemistry, while arts students study politics, history and geography.
