【题目】全世界范围内的石油和天然气资源正在日渐枯竭,煤炭再次成为了各国的能源重心。作为我国重要的煤炭基地,山西的煤炭资源已经仅剩能够维持200余年的储量,如何合理利用和有效开发越来越成为中国能源安全中一个不容忽视的关键问题。据此完成下列问题。

【1】在能源基地建设方面,晋中和晋北地区的主要限制性因素是( )

A.对外通道比较狭窄

B.环境污染比较严重

C.水源紧张

D.人地关系紧张

【2】山西能源基地建设有利于( )

北煤南运

西气东输

西电东送

西部开发

A.①②③

B.①③④

C.②③④

D.①②④

【3】属于缓解交通压力措施的是 ( )

加强铁路运输建设

辅以公路建设

变输出煤为输出电力

大力发展炼焦业

A.

B.①②

C.①②③

D.①②③④

【答案】

【1】C

【2】B

【3】C

【解析】

试题分析:

【1】山西省是我国重要的能源基地能源基地建设中会扩大开采规模;增加产量,同时把输煤为输电等;而煤炭开采、发电等耗水量大,晋中、晋北缺水严重,水资源紧张,故选项C正确。

【2】山西能源基地是我国北煤南运的输出地;同时也是西电东送的北部通道的电力来源地;山西能源基地有利于我国西部开发;西气东输的主气源在塔里木盆地,与山西能源基地建设无关,故选项B正确。

【3】加强山西能源基地建设,煤炭输出以铁路为主,应该加强铁路运输建设,辅以公路建设,可以缓解交通压力;变输出煤为输出电力,即减少了煤炭的运输量,可以缓解铁路等交通压力;大力发展炼焦业,焦炭等产品仍然需要输出,对缓解交通压力影响不大,故选项C正确。

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

How can a teen set themselves up for success? Here are some important points that you may find helpful.

Figure out your goals in life and work toward them. Start thinking about careers you would like to be in, but make a good choice based on your interests and strengths. 1 You could also work towards non-career related goals, such as creating your own fundraiser, getting good grades in school, joining in a team sport, etc. Challenge yourself and you’ll be surprised at what you can accomplish!

Don’t get into any trouble, legal or otherwise. It could ruin your future plans. Avoid the peer pressure and keep away from the cigarettes, alcohol, and drugs. 2 If you’re being pressured into anything, walk away. If you can avoid these things during your teen years, they’re a lot easier to avoid once you’re out of high school and away from peer pressure.

Have good friends to help you out! 3 Be with people who make you happy. Create a group of supportive, loving friends that can help you succeed in life and live your dreams. Find a few really good friends that will stick with you once you leave high school.

4 Join a sports team at school or out of school. Take your dog for a nice, long walk. Join a yoga group, go swimming at the local recreation center, or do sit-ups during commercial breaks on TV! Just exercise! 5 Studies show that people who are actively involved in activities in their teen years will be more active when they’re adults.

A. Get active!

B. Go for a run around your neighborhood.

C. This could be your job for the rest of your life!

D. You will start forming your own ideas this way.

E. It helps you feel better, mentally and physically.

F. Friends are there to support you and lift your spirits.

G. Obey the law and avoid ending up in the back of a police car.
