问题 解答题

甲、乙两位探险者到沙漠进行探险,没有了水,需要寻找水源,为了不致于走散,他们用两部对话机联系,已知对话机的有效距离为15千米,早晨8:00甲先出发,他以6千米/时的速度向东行走,1小时后乙出发,他以5千米/时的速度向北行进,上午10:00,甲、乙二人相距多远?还能保持联系吗?

答案

解:如图,甲从上午8:00到上午10:00一共走了2小时,

                  走了12千米,即OA=12;

      乙从上午9:00到上午10:00一共走了1小时,

                走了5千米,即OB=5;

     在Rt△OAB中,AB2=122十52=169,∴AB=13,

        因此,上午10:00时,甲、乙两人相距13千米;

        ∵15>13, ∴甲、乙两人还能保持联系。

答:上午10:00甲、乙两人相距13千米,两人还能保持联系。

阅读理解

要想成为最有吸引力的人,要注意生活中一些简单的细节。阅读下面六个有关如何成为最有吸引力的人的方法的描写,选出符合题中五个标题的选项,并在答题卡上将相应的选项的标号涂黑。选项中有一项多余选项。

_____1 Ask lots of questions

_____ 2. Great posture

_____ 3. Stay busy

_____ 4. Show your pearly whites ( or just smile)

_____5. Be interested in other persons

A.Don’t talk about yourself … remove attention from yourself. If you are interested in other persons, it will be helpful. And if you want to talk about yourself, you'll find that putting the other person first actually opens him up to return the favor and ask you questions. See how fun this is?

B.In other words, be humble. If you are a know-it-all (even if you really do know it all!), it really pushes people away. Rather, asking lots and lots of questions makes people feel like you care, you can be trusted, and you are... humble.

C.Walk like you know where you're going, and do so with good posture. Walk like you'll run over anyone who even attempts to hassle you. If you walk like this, you'll be spotted from a mile away.

D.Smile more, no matter how ugly your teeth are. I'm not kidding about this one. It's not all about the teeth. If you are smiling genuinely, you can draw everyone for 100 meters around to you.E. Perhaps you have seen someone who perhaps could be quite ugly but they have great posture and so suddenly they are really attractive? It's true. Your posture says a lot about you -- it says whether you have confidence, or simply if you really care. Talking physically, it is one of the most important physical characteristics you need !

F. Do you really know the power of this? We're told to stay busy to break away from  depression and feelings of anxiety. But did you know you should also stay busy to be really attractive? It's true. Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive. Always be busy with something, even if for some reason you have to make something up.
