判断以下英语句子的正误,说明原因.1.They wii arrive in Beijing on the morning.2.It's hot in the room,plesse keep the door open.3.Which bus does he need to take?4.The glass is full of hot water.5.We needn't to go to school on May 1st.6.He went to the party without inviting.第一个应是They will arrive in Beijing on the morning of March 5th.

1.正确。如果单是在早晨、下午、晚上，要用介词“in”，但要特指某一天的早晨，就得用介词“on”
2.please 拼写错误
3.正确。‘need’此处为实义动词，不是情态动词，后边跟动词要加“to”
4.正确
5.错误。去掉“needn't”后边的“to”，此处“need”为情态动词，后边跟动词原型。
6.错误。应该是被动形式“被邀请”，且without是介词，后边要跟动词的ing形式，所以是“without being invited”
