（6分）学习过“影响摩擦力大小的因素”后，李明同学想验证老师所讲的结论；小华同学发现实验室里有如图所示的铁块和木块。她想比较一下铁块表面和木块表面的粗糙程度，进行了如下实验：

a. 李明同学的实验：

（1）李明同学把长方体木块平放在水平桌面上，为了测出滑动摩擦力的大小，他用弹簧测力计水平桌面上          拉动木块运动．记下此时弹簧测力计的示数为F1。

（2）接着，他在木块上先后增加二个和四个钩码，重复步骤(1)，分别读出对应的弹簧测力计示数为F2和F3，发现F3>F2>F1，这说明                                                      。

（3）取下钩码．他又把该木块侧放在水平桌面上．按步骤(1)的方法再次读出弹簧测力计的示数．他这样操作是为了研究                                          。

b.小华同学的实验：

（1）因为要比较两者表面的粗糙程度，所以在同一水平桌面上做实验时，应保持            ___ ______不变。

（2）先将木块叠放在铁块上，用弹簧测力计匀速拉动它们。弹簧测力计的示数如图7所示，则桌面对物体的摩擦力为        N。

（3）然后，把铁块叠放在木块上，重复上述过程，这次测得的摩擦力为2.6N。通过上述实验现象可知：     ________的表面粗糙程度大一些。

Besides calling 911, here is what to do in some life-threatening emergencies when no one is around to help.

Lost in the wilderness

First, you’ve got to acknowledge you're in trouble. Stay where you can be seen, clearly and remember to rest. Keeping a sense of humor helps too -- it reduces strum and helps creative thinking. In a wide open area, make a colorful cress out of rocks to show your present position.

Choking

Aim to hit the top of the chair against your stomach, in the soft part below the bony upside-down V of the ribs (肋骨). Make a sudden push against the chair. If you still can’t breathe after six tries, call 911, even if you can’t talk. Write the word “choking” somewhere nearby, and leave the line open until help arrives.

Severe bleeding

Use your hand or clean cotton, or paper towels, or a scarf, or any cloth you can find, and push down on the wound until the bleeding stops. But if you put a band around your leg tightly, you’re going to close the vessels (血管) to the entire leg. In this way, you could loose foot.

Bear attack

If yon surprise a bear, don't run away. That invites an attack. Instead, stand up and back away slowly, without looking the bear in the eyes. If it does charge (猛冲) at you, stick out your chest, raise your arms, and spread your legs. Shout at the bear, to frighten it. If it's going to attack, lie facedown, with your hands held firmly behind your neck. Play dead until you're sure the bear is gone.

1. When you see a colorful cross made of rocks in the wilderness, you know ______.

A. someone is bleeding                  B. someone is choking

C. someone is lost                      D. someone is attacked by a bear

2. If you are still choking after six tries, you should ______.

A. keep a sense of humor                 B. call 911 and leave the line open

C. use your hand our clean cotton         D. lie down with your hands behind your neck

3. Don't tie around your bleeding leg tightly, or you could ______.

A. stop bleeding  B. reduce stress   C. loose your foot      D. cause breathlessness

4. The passage is mainly teaching us how to ______.

A. survive the emergencies                      B. avoid a bear attack.  

C. deal with a choke                         D. find our way
