Don't sit in the office all day .You should take more ___ (exercise).

1、Don't sit in the office all day .You should take more (exercise).别整天坐办公室.你应该多锻炼.more的后面是名词形式,不可数.2、Second,I take （C.exercise） every day.其次,我每天锻炼.take exercise,锻炼...我们老师说exercise要加s。。如果exercise指练习题、做操，可以加s，如do exercises。如果exercise指锻炼，则不加s，如take exercise。不可以 take exercises吗？一定要do exercises？是这样。
