_______

1. B 【细节理解】由文章中的"Please look at the first sign. It's a sign with the number 30 on it. When you see this sign, you must not drive at more than thirty kilometres an hour."可知,它是一个带有数字30 的标志。当你看到这个标志时,车速不得超过每小时 30 千米。所以第一个标志是"限速30"。2. A 【细节理解】由文章中的"You must drive carefully when you see the second sign, because you are getting close to a crossing now."可知,看到第二个标志时必须小心驾驶,因为你正在接近一个十字路口。所以第二个标志是"十字路口"。3. E 【细节理解】由文章中的"The third sign tells you there is a steep hill here."可知,第三个标志告诉你这里有一个陡坡。所以第三个标志是"上陡坡"。4. D 【细节理解】由文章中的"The fourth sign shows that the road gets narrow..."可知,第四个标志表示道路变窄。所以第四个标志是"两侧变窄"。5. C 【细节理解】由文章中的"The last sign means 'School Ahead, Go Slow'. You must watch carefully and drive slowly to avoid hitting the children."可知,最后一个标志意思是"前方学校,减速慢行",你必须仔细观察并缓慢行驶,以防撞到孩子。所以第五个标志是"注意儿童"。6. B 【词义猜测】由文章中的"The fourth sign shows that the road gets narrow, so it is necessary for you to drive slowly."可知,道路变窄时,为了安全驾驶时一定要减速。由此可推知,necessary 意为"必要的"。7. C 【细节理解】由文章中的"The last sign means 'School Ahead, Go Slow'."可知,该标志的目的是提醒司机在学校附近减速。8. Yes, I know the "Go straight" sign. It means vehicles must go straight, and turning left or right is not allowed.(答案合理即可)
