采用国际单位制,在力学中B

A.长度、质量和力是基本单位

B.速度、加速度和力是导出单位

C.m/s、m/s2和N是导出单位

D.密度的单位kg/m3是基本单位

答案

答案:C

物理中基本物理量总共有七个,即长度、质量、时间、、热力学温度、物质的量、电流、发光强度。长度、质量和时间是力学部分的三个基本量(高中阶段要求),所谓基本单位就是指基本量的单位。例如mm,cm,dm,m都是基本单位,但只有m是长度这个基本量的国际单位。除了七个基本量外的物理量都是导出量,他们的单位都是导出单位。故本题选择C.

Only three local students won Chinese Blog Competition. And 15 of the 18 awards went to students from China.

170 students’ task: to get a fully-designed blog up and running, complete with many postings based on a theme of choice—all written in Chinese.

Themes ranged from local opinions-such as the usage of Singlish, education and whether Singapore can be a cultural centre-to food blogs.

The entries were judged on Language proficiency(熟练程度)and the quality of writing, as well as the design and level of exchanging ideas with readers.

Academics(学者) from the National University of Singapore and the SIM University IT experts, and a journalist from Chinese newspaper Lianhe Zaobao in Singapore made up the judges.

In the end, only three Singaporean students made it to the award list—the rest of the awards were swept up by students from China.

“No surprise, ” said Mr. Chow Yaw Long, 37, teachers in charge from Innova Junior College, which organized the event. “Although the topics were local subjects, the foreign students were generally better in terms of the content of the posts and their grasp of the Chinese language. ”

One of the three local students winning the first prize in the Best Language Award was blogger Christina Gao 19, from the Saint Andrew’s Junior College, who spared no effort in researching for and writing her blog. Each entry took her between five and seven days to produce, complete with pictures and even podcasts
