do的动作“做”，它的承受对象是my homework；而be是系动词“是”，没有宾语，它和my homework连接起来的话不符合逻辑，翻译为“我需要成为我的作业今晚”
2.you seem___in a good mood today.
“你今天显得情绪是不错的”答案是:to be.；do是一个动作，不能用介词短语的in a good mood 做承受对象
需要表达“是、成为”时候该用to be ；需要表达“做、干某事”时候该用to do
1. 做作业需要do这个词。
2.这是系表结构，后面是一个介词短语，表示状态。
如果后面是需要做的事情，那就必须要用做啊！
记住do,doi,do就是做的意思。
be只有是的意思。
很高兴为你解答！
老师祝你学习进步！
请及时采纳哦！多谢你的问题！^_^
这个要看后面的词组是什么
1. do my homework 做家庭作业
2. be in good mood 心情好
Hi，很高兴为你解答！
如果帮到您，记得及时采纳哦O(∩_∩)O
还有其他疑问的话欢迎一起讨论！
1. do my homework。做作业。固定词组。
2. seem to be固定词组。似乎做某事。
你应该多熟记固定用法，你问的这些都是死记住的。祝学习进步，望及时采纳！~~~
一般来说 to do 表示一种动作，行动，是动态的；to be 表示一种状态，是静态的‘
第一题意思是我今晚需要完成家庭作业，是表示做家庭作业这一动作，故用to do;第二题意思是你今天看上去心情很好，表示的是一种状态，即心情好这一状态。故用to be。
清楚了吗？
