英语填空~~~要解释~~~有奖励啊~~

1.What language is the most widely _spoken__(speak)in the world?(这里需要speak的名词形式,而spoken恰好符合!
2.Yesterday a friend of __mine_(I)came to see me.(这里需要名词型物主代词,表明"我的……”
3.Kate is busy practising__running_(run)in the morning.(be practising doing sth.)
4.Zhao Mei is the _sadder__(sad)of the two sister.（这里是两个人,所以要用比较级,别一看见了the就只想着最高级）
5.The class 3 player _dropped__(drop)his stick on the growed and lost the race.（这是句由and引导的并列句主从句时态要一致,从句用过去式,主句也要用过去式）
6.The _death__(die)of his dog made him very sad.（这里要用die的名词形式,一定要搞清楚“die.dead.death.died"之间的区别）
7.__Luckily_(luck)the woman didn't hurt herself badly.（这题很简单,这里只是把副词提前,所以用"luckily")
8.Three quarter is another way of saying three _fourths__(four).（这里涉及到几分之几的用法,前面是复数,右面得用序数形式并加s)
9.In the gate _keeping__(keep)room,I meet one of my best friend.(这里表示在打扫房间时遇见了我的好朋友,表示的是动作的进行,所以加ing.)
