10、 four times a year等，它们准确地表达出事情发生的频率。I drink milk and eat vegetables every day. 我每天喝牛奶，吃蔬菜。I exercise once a week. 我每周锻炼一次。I visit my grandmother four times a year. 我一年看望我奶奶四次。二、易错点：sometimes. sometime, some time, some timessometimes意为“有时”，多用于一般现在时，对它进行提问常用how oftensometime副词，同some time，意为“在某时（过去或将来）
