Does 3. run 4. look 5. doesn't push 6. cross 7. feed 8. Be 9. can't 10. take 1. wait 解析：情态动词must后接动词原形，此处表示“必须排队”，故填wait。 2. Does 解析：句中often是一般现在时标志，主语your sister是第三人称单数，一般疑问句需用助动词Does开头，首字母大写，故填Does。 3. run 解析：Don't是祈使句的否定形式，后接动词原形，此处表示“不要跑或大喊”，故填run。 4. look 解析：情态动词should后接动词原形，look left and right是“左右看”，故填look。 5. doesn't push 解析：句中every morning是一般现在时标志，主语he是第三人称单数，否定句需用助动词doesn't，后接动词原形push，故填doesn't push。 6. cross 解析：Let's后接动词原形，是固定用法，cross the street表示“过马路”，故填cross。 7. feed 解析：情态动词mustn't（禁止）后接动词原形，feed the animals表示“喂动物”，故填feed。 8.

B 解析：考查情态动词辨析。must（必须）、mustn't（禁止）、should（应该）。句意“你禁止在公交车上跑，很危险”，结合语境选B。 3. A 解析：考查一般过去时的一般疑问句。助动词Did后接动词原形，remember是原形，remembers是第三人称单数，readed是错误形式（read过去式为read），故选A。 4. B 解析：考查一般现在时的一般疑问句。主语your brother是第三人称单数，助动词用Does，后接动词原形watch；Do用于复数主语，watches是第三人称单数形式，不符合，故选B。 5.

C 解析：考查一般过去时。yesterday afternoon是过去时标志，谓语动词用过去式，stand原形、are standing现在进行时、stood过去式，故选C。 8. C 解析：考查动词时态。结合句意“爸爸告诉我要遵守良好行为规范”，“告诉”的动作发生在过去，用过去式told；tell原形、tells第三人称单数，不符合语境，故选C。 9. B 解析：考查there be句型的否定句和时态。at midnight yesterday是过去时标志，排除A；any用于否定句，people是复数，be动词用were，否定式为weren't，故选B。 10. C 解析：考查动词时态。第一句陈述客观事实“他是个有礼貌的男孩”，用一般现在时，主语he是第三人称单数，be动词用is；第二句always是一般现在时标志，say的第三人称单数是says，故选C。三、句型转换 1. didn't follow 2. Should; cross 3. How important 4. weren't any 5. How long did; wait 6. What did; point 7. Was; quiet 8. were; signs 9. waited; for 10. What beautiful 1. didn't follow 解析：原句是一般过去时，改为否定句需加助动词didn't，后接动词原形follow，故填didn't follow。 2. Should; cross 解析：原句含情态动词should，改为一般疑问句时将should提前，后接动词原形cross，句首首字母大写，故填Should; cross。 3.

How long did; wait 解析：划线部分“for twenty minutes”是时间段，用how long提问；原句是一般过去时，需加助动词did，后接动词原形wait，故填How long did; wait。 6. What did; point 解析：划线部分“the 'No smoking' sign”是事物，用what提问；原句是一般过去时，需加助动词did，后接动词原形point，故填What did; point。 7. Was; quiet 解析：原句是含be动词was的一般过去时，改为一般疑问句时将was提前，后接形容词quiet，句首首字母大写，故填Was; quiet。 8. were; signs 解析：改为复数句时，be动词was变were，a sign变复数signs，故填were; signs。 9. waited; for 解析：用this morning改写，句子变为一般过去时，are waiting的过去式是waited，wait for是固定短语，故填waited; for。 10. How useful 解析：原句中的形容词是 useful，所以用 How 引导，后面直接跟形容词 useful，再接主语 traffic rules 和谓语 are。 四、补全对话 1. B 2. E 3. C 4. D 5. A 1. B 解析：根据答语“I saw a lot of signs...”可知，问句询问“在那里看到了什么”，选项B（你在那里看到了什么？）符合语境，故选B。 2.
