15.“做足够的运动”是do enough exercise，“做眼部运动”是do eye exercises ，什么时候作不可数名词，什么时候作可数名词？这里exercise泛指“运动、锻炼”，是不可数名词。“做眼部运动”是do eye exercises，这里exercises指具体的运动与锻炼项目，是可数名词。另外，exercise作“练习、习题”解时也是可数名词。
I have a lot of exercises to do.我有许多习题要做。
16.该上课了。
It's time for the class. 错误
It's time for class.正确
17.三班是获胜者
Class 3 was the winners. 错误
Class 3 were the winners. 正确
class在这里是集合名词，指“三班的运动员”，作主语时 动词用复数形式。在英语中，class, family, team等集合名词作主语，当做一个整体看待时，Be动词用单数形式，指其中的各个成员时，Be动词用复数形式。试比较
My family is a large one.
我家是个大家庭。
My family are having supper.
我们一家人正在吃晚饭
Class 3 is a good class.
三班是个好班级。
Class 3 are having an English lesson.

photo-photos照片 kilo-kilos 公斤
词尾为两个元音字母的词加-s，如：
zoo-zoos（动物园）radio-radios收音机
19.他们有多少只鸡？
How many chicken do they have? 错误
How many chickens do thay have? 正确
chicken在这里作为家禽的鸡时，是可数名词复数形式是chickens，作为食品的鸡肉时，是不可数名词，没有复数形式。
I like chicken very much.
我非常喜欢吃鸡肉。
20“一杯水”和“一杯茶”应该怎样说？
英美人喜欢用玻璃杯喝水，用瓷杯喝茶，所以“一杯水”习惯说：a glass of water一杯茶”习惯说：a cup of tea不可以说a cup of water或a glass of tea
21.请给我一瓶柳橙汁。
Please give me a bottle orange juice. 错误
Please give me a bottle of oranges juice.错误
Please give me a bottle of orange juice.正确
当orange juice作“柳橙汁”时是不可数名词，没有复数形式，表示“一瓶柳橙汁”应说a bottle of orange juice不可数名词需要计数时，前面需加表示单位的量词。如：
a piece of paper一张纸 a glass of milk 一杯牛奶
a bag of rice 一袋米 two cups of tea两杯茶
22.今天是九月十日，教师节。
Today is September 28th, Teachers' Day.错误
Today is September 28th, Teacher's Day.正确
表示人或有生命的东西的名词，其所有格加“ 's ”，所以“教师节”应为Teacher’s day。若复数名词不是以-s结尾的，仍需加-'s,如Children's Day 儿童节 Women’s Day妇女节
23.请你告诉我去公园的路好吗？
Can you tell me the road to the park?错误
Can you tell me the way to the park?正确
way 是指为了到达指定地点必须经过的地方，可以是街道、森林、田野、沙漠等。指抽象意义的“方向”“途中”只能用way，不能用road，road指两个地方中间能通车的大道。
24.What's the date today?和 What day is (it) today?分别是什么意思？
What's the date today?是问日期，意思是“今天是几号？”回答为Todayis May 1st今天是 5月1 日。另一个是是问星期几，意思是今天是星期几，回答是It’s Monday.“今天是星期几？”回答是：It’s Monday.
25.我去过纽约很多次。
I have been to New York many time.错误
I have been to New York many times.正常
time作“时间”解时是不可数名词，但作“次数”解时是可数名词，所以“很多次”应为many times或a lot of times “两次”要用twice不说 two times
