用连词填空
i often help him___he often help me
tom is verygood at chemistry____his brother does well in history
为什么比如第一个为什么要用and 不能用while。\(≧▽≦)/~
要在and but or while although 范围内
最好讲讲她们分别在什么情况下用

第一个填写and 第二个填写while
再问：为什么呢？大虾救我啊
再答：第一个填and表示一种顺接关系，就是很简单的我帮他，他也帮我第二个填while表示一种对比关系，Tom擅长化学而他的哥哥（或弟弟）擅长历史。
再问：那第二个用and的话呢为什么不行那就是，Tom擅长化学并且他的哥哥（或弟弟）擅长历史。我这样说对吗？
再答：这样的汉语你觉得通顺吗
再问：好吧。也谢谢Tracy_sun0101 尤文10皮队 empirequeen 蓝色的战争的回答
