读图回答下列问题。(共9分)

(1)要在海边建油港码头,应建在A处还是B处?为什么?  (3分)

                                                                                  

                                                                                  

                                                                                  。

(2)欲从油矿区向油港铺设输油管道,线路如图中虚线所示,请说明理由。(2分)

                                                                                 

                                                                                 

                                                                                 。 

(3)C、D两地高程相等,从C地登上甲山顶,有什么有利和不利条件?(2分)

                                                                                 

                                                                                 

                                                                                  

(4)B处在甲山顶的什么方向?          ,D、G两地的相对高度是多少?              。(2分)

答案

(1)B处 (1分) ① 该处等深线密集,水深;②是小港湾,易于避风;③离油矿近,运输方便 (2分)

(2)①铺设工程简单方便;②要从高处向低处自流(2分)

(3)C处有利条件是直线路程短     不利条件是坡度陡 (2分)

(4) 东    0~50米之间(2分)

题目分析:

(1)港口建设要考虑航行条件和停泊条件。航行条件主要考虑水深,等深线密集处,从海岸向外深度下降快,沿海的水比较深,便于船舶的航行和停泊;港湾便于船舶停泊和避风,利于建设港口;另外靠近货物地,可以减少货物运到港口的运输费用,从上述三个方面考虑油港码头适合建在B处。

(2)沿等高线修筑输油管道,可以减少铺设管道的工程量,减少工程的投资;地势由高到低铺设输油管道,可以减少输油的运输费用,铺设的理由也就主要从这两个方面说明。

(3)登山的有利条件和不利条件主要从登山的路程和登山的坡度两个方面说明。从C、D两处到山顶的距离远近,得到C处登上山顶直线距离短的有利条件,但C到山顶的等高线较密,坡度较陡对登山不利,由此得到第(3)题的答案。

(4)根据图中的指向标确定B在山顶的什么方向,图中与指向标相反的方向为南方,与南北方向垂直的左侧是西方,右侧是东方,B在右侧,所以B在山顶的东方。D点在100米等高线上,G点在100米、150米两条等高线之间,因此D、G两地的相对高度在0~50米之间。

In 2006, a large number of new Internet sites became popular around the world. Some of these are for communication, others for entertainment(娱乐).

The blog is one form of communication that increased in popularity. Through these personal websites(网址), people can share their lives, ideas and opinions on the Internet. People of all ages have their own blogs. For young people, they are a way to show their writing and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas with other teachers’, as well as experiences and concerns about their work.

YouTube is another Internet site that became more popular last year. This website lets anyone create, share and watch short videos.

The industry earns more than one billion(十亿) dollars each year from publications, memberships and other costs.
