If it _____ tomorrow, I _____ _____ at home. rains will stay If it ____ sunny tomorrow, they _____ _____ a trip. It will be sunny tomorrow.

I’ll go with you if you don’t want to go alone. 2) 主句是含有情态动词 may/ might/ can/ must/ should 等的句子。从句要用一般现在时。 （主情从现） eg: If you want to be healthy, you should eat less meat. If you finish your homework, you can go home now. 3) 主句是祈使句时，从句也用一般现在时。 （主祈从现） eg: Please let me know if someone calls me. Don't play basketball if you don't finish your homework. 注意： 为了避免重复，条件状语从句中常使用do( does, did ) 来代替上文提到的动作。 - I think I will ride my bike. - If you do, you'll be late. 条件状语从句 其他引导词： unless(除非，如果不)=if...not so/as long as(只要) in case(万一) once(一旦) 1.You will never gain success you are fully devoted to your work. 2.The doctor share his phone number with the patient _____ they need medical assistance. 3. you have a dream, keep working hard and you will succeed. 4.You will be successful in the interview _____ you have confidence. unless 如果不，除非 in case 以防万一 As long as 只要 once 一旦 Task 2:Find the precious.
