上述仪器还有的共同特点是:(只要求写出2个)

(1)______;

(2)______.

答案

因为刻度尺是用来测量长度的、温度计是用来测量温度的、量筒是用来测量体积的多少的、测力计是用来测量力的大小的、电流表是用来测量电流的大小的、电压表是用来测量电压的大小的,因此他们都是用来测量不同物理量的仪器,即它们都是测量仪器,并且他们都有分度值,刻度线分布也是均匀的等.

故答案为 它们都是测量仪器;它们都有分度值;它们刻度线的分布都是均匀的.

Yao Ming edged Kobe Bryant as the top votegetter in fan ballotingfor the 55th NBA All-Star game Thursday, and Shaquille O’Neal became the fifth player in league history to earn 13 consecutiveselections for the midseason showcase.

Yao and Tracy McGrady give the host Houston Rockets two starters in the Feb.19 game. They were joined on the Western Conference squad by Bryant, San Antonio’s Tim Duncan and reigning MVP Steve Nash of Phoenix — who will be a first-time All-Star starter.

Yao edged Bryant by 71,107 votes for the top overall spot in the balloting, despite missing 21 games following surgery to clean out an infection in his left big toe. It’s the fourth All-Star trip for the 7-foot-6 center from China and the eighth for Bryant, who leads the NBA in scoring and had an 81-point effort — the second-biggest night in NBA history — last month in the Los Angeles Lakers’ win over Toronto.

Yao finished with 2,342,738 votes; Bryant had 2,271,631 in the closest finish among the top two players in All-Star balloting since Vince Carter, then of Toronto, edged Miami’s Alonzo Mourning by 33,385 votes in 2000.

①    ballot  vi. 投票

②    consecutive  adj. 连续的
