我们该上英语课了.It's time _____us_____ ______English.

如果有class i think using a "take or attend" would be better. we can't say to study or learn English class, we can say to study/learn English; 也就是说我们不能说学习learn英语课，只能说上take/attend 英语课 而也不用have,because 1.have/has后的class 一般变单复数，eg. has an English class or have English classess 这是形式上 2。意义上（这是最重要的）have 永远都有一种“有什么”的这个意思在里面（特别是当他作为实义动词时。而上句不是能说是时间有英语课，这显然不太好，而是说是时间上课了，take **class or attend **class means The teacher will be coming, we should go and to study now.So we say it's time for us to take/attend(attend is more formal) English class. 你也会见到这样说的we say " it's about time/ high time (for sb.) to do sth. 补充：有朋友如果用虚礼语气可以说It's time /about time /high time (that可省） we took （一定用过去式，也就是说此句子意思要是用重句时，重句一定用虚礼语气句型）attended English class.
