四位同学
食物类型牛肉干蛋糕水果

A.甲

B.乙

C.丙

D.丁

答案

蛋白质是构成人体组织细胞的基本物质,人体的生长发育、组织的更新等都离不开蛋白质.糖类是人体最重要的供能物质,人体进行各项生命活动所消耗的能量主要来自于糖类的氧化分解,脂肪也是供能物质,但是人体的大部分脂肪作为备用能源储存在皮下等处,属于人体备用的能源物质.水、无机盐、维生素不能为人体提供能量.

 甲中的牛肉干主要含蛋白质,乙中的糖是主要的供能物质,丙中的蛋糕主要提供淀粉、脂肪和糖类,其中淀粉和脂肪也能提供能量,但速度较糖类慢,丁中的水果主要提供维生素和无机盐.

      Computer technology (技术) has become an important part of people's life. This technology has its

own special words. One well-known computer word is Google. It is the name of a popular "search engine

(引擎)" for the Internet.

      People use the search engine to find information about almost any subject on the Internet. The people

who started the company named it Google because in math Google is a very large number-one hundred

zeros follow the number one. When you "Google" a subject, you can get a lot of information about it.

      If you Google someone, you might find that person's name on a blog. A blog (博客) is short for a Web

log. It is a personal Web page. Some people write blogs to express their opinions and ideas over the Internet.

Some use them to share their lives with faraway friends or family. Others write blogs to help them deal with

sickness, money problems or to choose movies to see or books to read. Some people add information to their

blogs every day. People who have blogs are called bloggers.
