III. Cloze Test （16-25 題，共 10 題） A. 16-20 English has 1,120 different ways of spelling its 40 phonemes, the 16 required to pronounce all its words. 17 , Italian needs only 33 combinations of letters to spell out its 25 phonemes. 18 , reading Italian takes a lot less effort, and that’s probably why the reported rate of dyslexia in Italy is barely half that in the U. S., where about 15% of the population is affected to varying degrees. 19 , Americans spend more than $1 billion a year to help their kids cope with dyslexia. Many Italian dyslexics, 20 , aren’t even aware they have a problem—and would notice it only if given a battery of psychological test.
