“200人的班级中只有三人获奖”英文怎么说？

有很多种说法,看你想用什么试：
1） There are (only) 3 people out of 200 that were awarded this honor in the class(你忘了这个）.

only可要可不要，如果你想强调这个句子那就用only!

2)The honor is(Present tense)/was(Past tense) awarded to only 3 people out of 200 in the class.

3)The honor has been won by only 3 people out of 200 in the class.

4）3 people, out of a class of 200, have won the honor.

5) A class of 200 people, but only 3 won the honor!

还有很多，我就不一一的说了~~~~ 不过有一点我想说说-最好把那个奖加上去，例如：
the honor of being environment friendly(爱护环境奖）

希望能帮到你！

其实英语翻译很随便的 你那个也行
我的翻译是
There are only three winners of a 200 person class.

Only three out of a class of 200 have won the prizes.

你的说法也行， 把 was 改成 were

In 200-person class,the number who won awards is only three.
