The first and most obvious thing is that a dictionary will【23】you the spelling of a word. If you' re not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in alphabetical order--a, b, c, and so on .For example, on a dictionary page the word "poor" p, o, o, r--comes before "poverty"--p, o, v, e, r, t, y and the word "poverty" comes【24】the word "power'--p, o, w, e, r. The words are always given in alphabetical Order.
The second thing a dictionary will tell you is【25】. Most dictionaries give the pronunciation of a word in a special kind of alphabet. This special alphabet is called a phonetic, or sound alphabet. The phonetic spelling will tell you generally【26】a word is pronounced. There are a few different phonetic alphabets. Many dictionaries use the International Phonetic Alphabet to show pronunciation.
The【27】thing a dictionary will tell you is the meanings of words. You can【28】a word and find out what it means. Many words have more than one meaning, and a good dictionary will ex plain all of the word' s meanings. For example, in English the common word" get" has over 20 different meanings. The meaning, of course,【29】the sentence in which the word' is used.
These three things--spelling, pronunciation, and meanings--are some of the important【30】that you learn from dictionaries.

The source of the sun' s inconstancy is magnetism. Professor William Livingston has developed new theories about its magnetic nature.
"We don' t yet know what causes sun spots, "he says, "but we now think they ' re areas of high level magnetism that come up from the sun' s interior. So strong is their magnetic pull that the highly ionized gas nearby is not able to transmit energy out. "As a result these areas send out less heat and light and thus appear from Earth to be almost dark irregular surface patches.
Sun spot activity generally fluctuates in steady, 11-year cycled. Scientists have long formed the o pinion that as the size and number of sun spots increased, the overall energy sent out by the sun would de crease. Indeed, recent studies confirmed it, revealing that during peak periods of sun spot activity, the Earth experiences a small drop that can be seen clearly in received solar energy.
Could such a small drop in energy have an effect here on earth? Perhaps some scientists think the world temperature could fall by' as much as 0.2 during periods of high solar magnetism.., enough to cause significant fluctuations in weather patterns.
According to the passage, it is believed that the sun ______ .
A.moves in a quick but steady way year after year
B.sends out less and less heat and light with each passing year
C.radiates the same amount of light every year
D.might have a strong influence on the weather patterns
Societies differ in how they structure marriage relationships. Four patterns are found: monogamy, one husband and one wife are found; polygyny, one husband and two or more wives; polyandry, two or more husbands and one wife; and group marriage, two or more husbands and two or more wives. Although monogamy exists in all societies, Murdock discovered that other forms may be not only allowed but preferred. Of 238 societies in this sample, only about one-fifth were strictly monogamous.
Polygyny has been widely practiced throughout the world. The Old Testament reports that both King David and King Solomon had several wives. In his cross-cultural sample of 238 societies, Murdock found that 193 of them permitted husbands to take several wives. In one-third of these polygynous societies, however, less than one-fifth of the married men had more than one wife. Usually it is only the rich men in a society who can afford to support more than one family.
In contrast with polygyny, polyandry is rare among the world's societies. And in practice, polyandry has not usually allowed freedom of mate selection for women; it has often meant simply that younger brothers have sexual access to the wife of an older brother. Thus where a father is unable to afford wives for each of his sons, he may secure a wife for only his oldest son.
