题目内容
18．We will insist on it until shechanges （change） her idea．分析 直到她改变主意之前，我们都将会坚持它．
解答 答案：changes 根据until前后都是句子，可知此处的until是作为连词的．并且主句"We will insist on it"为一般将来时．故从句中应用一般现在时．（主将从现原则）．根据主语she，可知其后的动词应该用第三人称单数形式．故答案为changes．
点评 本题考查从句中的时态问题．符合主将从现原则的连词还有if、as soon as等．

9．Many earthquakes happen every year．Some of these earthquakes are very strong．When they happen in cities，they can be very serious．Many people will be hurt or die in the earthquakes．Knowing some ways to protect yourself will help to keep you safe in the earthquake．
If you are indoors when the earthquake happens，the safest place is under a strong table or desk．Sitting on the floor in a doorway or close to a wall is safer than standing in the middle of a room．Remember to protect your head and neck with your arms．Stay away from windows，tall furniture and pictures or anything that may fall on you．Do not try to run out of the building．
If you are out of doors，move to clear areas．Get away from buildings and trees．Be very careful of fallen power lines．
The danger is not over when the strong shaking stops．There will be some shocks after most earthquakes．We call them aftershocks and they sometimes can be more dangerous than the first earthquake．
When it is safe for you to move around，check the people near you．Some may need help．You may feel afraid，but you should try to stay calm．That is the most important thing to do in the earthquake．
