2021年贵州专升本考试考试真题卷（5）本卷共分为1大题50小题，作答时间为180分钟，总分100分，60分及格。一、单项选择题（共50题，每题2分。每题的备选项中，只有一个最符合题意） 1.Most dictionaries will tell you a number of (21) about a language. There are three things in particular that (22) important. These three things are spelling, pronunciation, and meanings. 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.25（）AbooksBpeopleCthingsDthing2.Most dictionaries will tell you a number of (21) about a language.
