问题 问答题

(1)图中位于热带的是______,判断的依据是______.

(2)图中位于寒带的是______,判断的依据是______.

(3)图中位于南半球的是______,判断的依据______.

(4)四图中,气温曲线的弯曲程度是不一样.请你计算:A和B地的气温年较差分别是______℃和______℃.因此,气温曲线越弯曲,气温年较差(气温变化)越______.

(5)从气温变化看:A地是四季分明,B地是______,D地是______.

答案

(1)热带是最低月平均气温在15℃以上,B图最冷月平均气温在15℃,所以B为热带地区.

    (2)寒带是最高月平均气温小于10℃,D图最高月平均气温小于10℃,所以D为寒带地区.

    (3)12、1、2三个月气温最高为南半球,C图12、1、2三个月气温最高,所以为南半球图.

    (4)气温年较差=一年中最热月平均气温-一年中最冷月平均气温,A图最热月平均气温为25℃,最冷月平均气温为-5℃,气温年较差=25-(-5)=30℃,B图最热月平均气温为28℃,最冷月平均气温为25℃,气温年较差=28-25=3℃,从计算结果可以看出,气温曲线越弯曲气温变化就越大.

    (5)从A.B.D三幅图可以看出,A温带地区四季分明,B热带地区终年高温,C寒带地区终年严寒.

故答案为:(1)B;冬季最冷月平均气温在15℃以上;(2)D;最热月气温在10℃以下;(3)C;12、1、2三个月气温最高;(4)30;3;大;(5)终年高温;终年严寒.

Do you know how to prepare for and survive a major earthquake? According to Department of Conservation scientists, it is important to have the right answer to that question.

How to Be Prepared

Electricity, water, gas and telephones may not be working after an earthquake. The police and fire departments are likely to be tied up. You should be prepared to fend for yourself at least three days,preferably for a week. You’ll need food, water and so on. It’s also a good idea to decide ahead of time how and where your family will reunite if separated during a quake. You might choose an out-of-the-area friend or relative that family members can call to check on you.

________

If you’re indoors, stay there. Get under a desk or table. The kitchen is a particularly dangerous spot. If you’re in an office building, stay away from windows and outside walls and do not use the elevator. If you’re outside, get into the open. Stay clear of buildings, power lines or anything else that could fall on you. If you’re driving, move the car out of traffic and stop. Avoid parking under or on bridges or overpasses.

After an Earthquake

Check for fire. If you smell gas, shut off the main gas valve(阀). If there’s sign of damage to electricial wiring, shut off the power at the control box. If the phone is working, only use it in case of emergency(紧急情况). Avoid driving if possible to keep the streets clear for emergency vehicles. Be careful that things may fall out of cupboards when the door is opened, and also that chimneys can be weakened and fall with just a touch. Listen to the radio for important information and instructions. Remember that aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes. If you leave home, leave a message telling your friends and family your location.
