Mrs Smith have been teaching us about kites．She told us that they were invented in China in more than 2，300years ago．When our teacher asked us to design a kite it could fly，we started our pairs work at once．
First，we collected the materials we need．Tara brought the big plastic bag to school．I persuaded my dad to let me have some masking tape that left over last week where we had been spraying the rusty （生锈的） patch on the car．I also found some thin poles．But either Tara nor I could find any string at home，so we will get some for our pocket money on the way home tonight．
1．have﹣has．考查主谓一致．主语是Mrs Smith 所以谓语动词用第三人称单数．
2．去掉in．考查介词．表示"一段时间以前"用"…ago"，in用于将来时，表示一段时间以后．
3．it﹣that/which．考查关系词．从句子 our teacher asked us to design a kite it could fly可知 it could fly是定语从句，先行词是a kite，表示老师要求我们设计一个能飞的风筝，所以用that/which代指先行词，做从句的主语．it不能引导定语从句．
4．pairs﹣pair．考查名词复数．pair做定语修饰work，所以不能用复数．
5．need﹣needed．考查动词的时态．根据上文可知作者讲述曾经做风筝的经历，所以用need的过去式．
6 the﹣a．考查冠词．第一次提到big plastic bag，表示一个大塑料袋，用不定冠词．
7．left前加was．考查被动语态．在I persuaded my dad to let me have some masking tape that left over last week中 that left over last week是定语从句，先行词是 some masking tape，表示胶带是上周剩下的，所以谓语用was left．
8．where﹣when．考查关系词．在I persuaded my dad to let me have some masking tape that left over last week where we had been spraying the rusty （生锈的） patch on the car．中，we had been spraying the rusty （生锈的） patch on the car是定语从句，先行词是last week，表示在上周，我们修补汽车的生锈部分．所以用when．
9．either﹣neither．考查不定代词．either…or表示"或者…或者"；neither…nor表示"既不…也不"，本句 either Tara nor I could find any string at home表示Tara和我都不能找到铁丝，所以用neither…nor．
10．for﹣with．考查介词．本句we will get some for our pocket money on the way home tonight．表示我们用零花钱买铁丝，所以for改为with，表示"用"．
