短文改错Ann and Cindy became rival since their first day at school.Wanting to sit on same chair...

Answer 1

Ann and Cindy became rival since their first day at school.Wanting to sit on same chair had started it. All through its school years they fought for be number one in academic work and sports.At the Christmas party they compete to win the prize for the best cake.

第一句rival应该是rivals(对手都是成对出现的，所以要用复数哦)。
第二句的那个，sit on the same chair,（同一张椅子，the same，same在表示同一个的时候，都是the same这样出现的）
第三句fought for后边应该接sth，所以那个be直接删除就是了。
第四句，时态有问题——上文全部都是过去时，所以那个compete变成competed就是了。

我看到你之前的追问，已经修改了答案了，应该都是一句一错的改错吧，呵呵~~

Answer 2

wanting改having wanted,want应该用过去时，但ed形式开头的不能放句首，只能用having done?

Answer 3

Ann and Cindy became rivals（应该用复数形式） since their first day at schoo.

追答

Wanting to sit on "the" （same的前面要加定冠词the，表示“同一把椅子”）same chair had started it.
All through its schood years they fought "to"(一种改法是把 for 改成 to，用动词不定式符号to才能连接下面的另一个动词 be）be number one in academic work and sports. 另一种改法是把be去掉，fought for number one
At "a" Christmas party(如果前文没有提到过这次圣诞聚会，就不能用定冠词the，而要用不定冠词a，表示“在一次圣诞聚会上”；否则，如果前文提到过这次聚会，那么用the是正确的 ), they “competed”（既然是已经都发生过的事情了，谓语动词自然应该使用过去式） to win the prize for the best cake.
