美国宇航局和欧洲航天局3日发布了哈勃太空望远镜对矮星系NGC4449拍摄的一张照片,它展现了这个星系中恒星诞生的情景。在照片上,数以百计的蓝色和红色恒星闪闪发光,由大恒星组成的蓝白色星簇遍布各处,新的恒星正在弥漫的红色尘云中诞生。NGC4449是猎犬座方向上一群星系中的一个,天文学家认为这个星系里恒星的诞生受到了一些邻近星系的影响。恒星在星系中诞生是很普通的事,但目前NGC4449里的恒星诞生活动格外剧烈,达到了“星暴”的程度。据分析,这可能是该星系与另一个较小星系碰撞融合所致。

     In June, 2007, a group of students from eight high schools in Winnipeg, the capital of Canada's Manitoba

province, will begin test-launching (试发射) a satellite the size of a Rubik's cube.

     The one-kilogram Win-Cub satellite, named for its home city and its shape, will be put into low orbit. Once

in space, it can perform for a few months or up to several years, communicating information that could help

find the signs of earthquakes.

     There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind

in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in

cooperation with aerospace (航空航天的) experts and 10 students from the University of Manitoba, and with

support from two other organizations.

     The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing

high school students to have an opportunity to learn more about the exciting world of engineering through their

participation in this challenging program. It is also taken as a wonderful example of the unique partnerships

within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-

class educational project into reality and Manitoba closer to space.

     "These Manitoba high school students deserve congratulations for their enthusiasm, innovation (创新), and

a strong love for discovery," said Education, Citizenship and Youth Minister Peter Bjomson. "We want to make

science more relevant (相关的), interesting and attractive to high school students by showing them how

classroom studies can relate to practical experience in the workplace or, in this case, in space," Bjomson added.

     The Win-Cube program is mainly named at inspiring a strong desire for discovery on the part of the students.

It also shows Manitoba's devotion to research and innovation and the development of a skilled workforce-all

important drivers of knowledge-based economic growth.

D. scientific research is too far away from high school students

3. The primary purpose of the project is to _____.

A. find the early signs of earthquakes

B. relate studies to practical

C. help high school students study real-world engineering

D. inspire a strong desire for discovery among the students

4. The best title for this passage may be _____.

A. Manitoba School

B. Win-Cube Program

C. Space Co-operation

D. Satellite Launching
