A.有四季现象

B.全年皆夏

C.四季如春

D.全年皆冬

答案

小题1:B  

小题2:A

题目分析:

小题1:由于地球是围绕地轴自转的,所以在地球上不同的纬度自转线速度不同,赤道上线速度最大越往两极越小,至南北极点,自转线速度为0。地球的平均半径为6371km,由此可计算出赤道的周长是4万千米,地球一天旋转一周,所以在赤道上一天运行的距离应是地球赤道的长度4万千米(八万里),由图可知,c在赤道上,所以应为c点的自转速度,选项B正确;a、b和d自转速度应小于8万千米/天。

小题2:地球上不同纬度范围,一年四季表现不同。热带地区,终年高温,全年皆夏;寒带地区,终年低温,全年皆冬;温带地区,夏季高温,冬季寒冷,四季分明;所以选项A正确;四季如春主要发生在低纬度的高原上,由于海拔高导致夏季不热;由于纬度低导致冬季不冷,从而形成四季如春的气候。

阅读理解

     Loma just had to get in touch with someone: "I had to tell my best friend something important. I tried

calling her but I couldn't get through. So I sent her an e-mail and then I spoke to her on MSN. Without

technology I would not have been able to tell her. "

     Staying connected with friends and family is important for us. That's why we asked our readers to tell

us how cell-phones, e-mail, blogs, text messaging, and personal pages help them keep in touch. More

than 1,500 responded.

     Most of them told us they couldn't live without technology: 80%of teens said they need technology to

stay in touch. Almost 30%said they'd be completely out of their friends without their cell-phones and

other methods of communication.

     What do they do when they've got news they need to share now? Most teens say they try to reach

their friends by phone. But if they don't reach them, they use QQ, e-mails, and text messaging to get the

words out.

     Lots of people use one way of communication-like text messaging-to get a friend's attention and then

use another where they can talk more. "My friends and I always tell each other everything that happens.

So I send them text messages to tell them to come online so we can talk about it," said Sabeiha.

     "When planning to get together with friends", Julian said, "the easiest and fastest way I know is to

send a text message to my contact group." Jocelyn said. "If I want to go to see a movie with a few

friends, I usually send text message to them. By telephone, you have to call every single friend one by

one. But text messaging allows you to send the same message to as many as you'd like, which saves a lot

of time."
