【2】RS主要功能是拍摄遥感图像,GIS主要功能是分析处理信息。如果墨西哥湾出现了严重的石油泄漏污染事件,利用RS的遥感图像和GPS技术对信息进行分析、处理,可以监测石油污染的海区范围,对。无法监测海底漏油点的石油日泄漏量,错。可以监测石油污染物扩散的速度,对。不能监测污染海区海洋生物种类的变化,错。C对。A、B、D错。

【3】投资商在某城市内进行大型购物中心区位选择时,可利用该城市的GIS系统作综合分析,主要是分析交通通达度高,人口密度大的区域。所以调取的主要参考图层是交通图层和人口图层,D对。地形图层、供应商分布图层、服务企业图层、通讯图层、工业区图层不是商业区的主要影响因素,A、B、C错。

【题目】 请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

注意:每个空格只填1个单词。

I used to be the messiest person alive.Over the years, through watching others and by trial and error, I have finally found ways to come up with plans, organize them and follow through with them.

Make an outline of everything you need to have and do to make your plan happen.Make a list of all of the steps that need to be accomplished and think about what needs to be done.

Detail everything thoroughly and read over it so you can start coming up with some mental solutions of how to carry out your plans.

You should ensure that if for some reason way one doesn’t work, you have way two and way three to lean back on.Therefore, different ways are needed at hand.It’s just a matter of being organized.Chances are that there is always more than one way of doing things, and chances are that if one of those ways doesn’t work, one of the other ones will.

Committing yourself to finishing at least part if not all of your plan at once is also necessary.It will show that you not only have initiative to get things rolling, but that you are interested in the results obtained with making the move to get everything done.

If you make a commitment to finish before a specific time, make sure that you carry that out, and be sure to do everything in the way you said you would, within the time-frame you set for yourself.

Don’t try to tackle more things all at a time.All that does is delay your progress, distract you and make you lose your interest, motivation and energy.

Carrying out an effective plan requires being as organized as possible.You will only achieve this by sticking to the order of the plan and not deviating or trying to do more at a time.

Last but not least, you should never abandon things mid-project.It will only annoy everyone around you including yourself.Unfinished plans are a waste of time, energy and, in some cases, even money.

So, don’t be afraid of organization.The older we get, the more necessary it becomes to have the skills to follow through with confidence and to be able to carry through plans in an organized and manageable way.It pays to be organized, after all.

More and more foreigners like to come to China. Last Friday our school was invited a foreign teacher in our city give a class to the students of Senior Grade Two. We found his class interested. I learned a lot from him. The teacher had a free talk to us with easy English. He spoke slow so that we could understand him well. Sometimes he repeated what we don’t understand. My classmates were all active in the class. To his joy, I understood everything the teacher said. And I was able to ask question in English. This class encouraged me very much. I’m sure that until we keep on practicing, it will be easy for us to learn speaking English well.

How can a person recover from emotional problems? A popular opinion suggests that he watches

humorous films. And a recent study proves this to be wrong. The study also shows

that watching at sad films can make getting over a negative mood a easier job. Emotional

experiences is important to people’s well-being. People are less likely to share their feelings

with these who have had similar experiences. Similar, people prefer movies that reflect their

mood. That’s the reason a sad film can contribute to comfort a sad person more than a

pleasant one.
