The sweet music of that laughter 5 (bring) back a hundred memories of winters past. I remembered 6 (catch) snowflakes on my tongue , building snowmen , making snow angels , sledding 7 hills, and always losing the snowball fights with first my brothers and then my own children. Standing there in that warm coat of remembering made the wind a little less cold. I turned up my head, stuck out my tongue , 8 for the first time in years caught a snowflake on it.

情态动词 情态动词是一种本身有一定的词义，但要与动词原形及其被动语态一起使用，给谓语动词增添情态色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后面加动词原形。 情态动词有四类： ①只做情态动词：must,can(could),may(might)…… ②可做情态动词又可做实义动词：need，will ③具有情态动词特征：have(had,has) to,used to，ought to ④情态动词表猜测：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。） 注：mustn't代表强烈禁止 must表示主观，have to表示客观。 常用的有：can may could must have use . 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。 情态动词表推测的用法小结 （一）情态动词表推测的三种句式 1．在肯定句中一般用must （一定），can,could（可能），might /may（也许，或许）。 e.g:(1)He must/can/may,might know the answer to this question. 他一定/可能/也许知道这个问题的答案。 (2)It is cold in the room. They must have turned off the heating. 屋里很冷，他们肯定把暖气关了。 2．否定句中用can’t / couldn’t（不可能），may not/might not（可能不）。
