(4)根据古马里帝国所处的地理环境,分析其兴盛的可能原因。 

    _________________________________________________________________________________________

答案

(1)变化趋势:水量减少。原因:该河段所处区域降水量少,蒸发量大(流经半干旱、干旱地区);少

    支流汇入;河水下渗严重。

(2)主要差异:甲地降水明显多于乙地。原因:甲地受来自海洋的西南气流和沿岸暖流影响,地处山地

    迎风地带,降水丰富;乙地地形平坦,西南气流受地形抬升不显著,并受离岸寒流影响,降水较少。

(3)水稻种植经验不足,生产技术落后;水利设施不完善,机械化程度低;传统生产观念和主食消费习

    惯的影响。

(4)地形平坦;草原广阔;河流水资源较丰富;灌溉农业及牧业较发达;处于古代贸易的交通要道。

     This year in your grade you will have a lot of reading to do. You can do more of it in less time if you learn

to read rapidly.

     Perhaps you have been told about some habits which keep a person from reading fast and have been strongly

asked to break those habits which you might have.

     Do you still have any of these bad habits? Check yourself by answering "yes" or "no" to these questions:

     a. Do you move your lips when reading silently?

     b. Do you point to those words with your fingers as you read?

     c. Do you move your head from side to side as you read?

     d. Do you read one word at a time?

     If you answer "yes" to any of these questions, start at once to break the habit. If you move your lips, hold

your fingers over them, or hold a piece of paper between your lips while you are reading. Then if your lips

move, you will know it and stop them moving.

     If you point to words, hold the two sides of your book, one side with your left hand, the other side with your

right hand. Then you won't have a free finger to use in pointing while reading. If you move your head, place

your chin in one hand, and hold your head still.

     If you read no more than one or two or three words at a time, you need to work very hard in learning to take

in more words at each glance when your eyes are traveling across the lines of words.

     Even if you do read fairly fast now, you can learn to read even faster. As you probably have been told, the

secret of fast reading is to take in whole groups of words at each glance. Read in groups and force your eyes

along the lines of words as fast as you can make them go. Anyone who practices doing these two things will

be able to read faster.

1. While reading, you should _____.

A. not hold your books with your hands

B. not keep your head still

C. not use your finger to point to the words

D. do all of the things mentioned in A, B and C

2. You may hold your fingers over your lips when you read so as _____.

A. to feel whether your lips move or not

B. to tell others to be silent

C. to keep yourself from talking to others

D. to hold a piece of paper between them

3. When your eyes travel across the lines of words, _____.

A. you need to read the words out

B. you need look at every word carefully

C. you need to remember every word

D. you need to read several words at a time

4. If you can read fairly fast now, _____.

A. you don't need to learn to read faster

B. you can learn to read even faster

C. you can go on reading like that

D. you can enjoy reading
