Mike is an American boy. At an American school,(student/students) meet their class teachers at the start of the (day/days).

Mike is in the science (club/clubs).At the club, he makes (friends/friend) with students from America and other(country/countries). 答案：students, days, classrooms, activities, club, friends, countries 解析： 1. “student”是单数形式，根据句意，这里说的是很多学生，所以用复数“students”。 2. “day”指一天，这里说的是在学校的每一天，所以用复数“days”。 3. “classroom”是单数，根据“different”可知要用复数“classrooms”。 4. “activity”是单数，“club activities”指俱乐部活动，不止一个活动，要用复数“activities”。 5. “science club”是指科学俱乐部，是一个整体，用单数。 6. “friend”是单数，“make friends”是固定短语，表示“交朋友”，要用复数“friends”。 7. “country”是单数，“other”后接复数名词，所以用“countries”。 Activity 1: Pair work. Read the conversation.Pay attention to there be. What's in the big box? There are some bottles in it. Is there any water in the bottles? No, there isn't. But there is some juice. Are there any toys in the small boxes? Yes, there are. 思考与总结： 1. “there be”句型的结构是怎样的？ 2. 如何区分“there is”和“there are”的使用？ Activity 2: Complete the table and learn how to use there be. Singular noun Plural nounPositive There is (There’s)...Negative There is not (There isn't)...Question Is there a/an/any...?Yes Yes, there is.Short answer No, there isn't.用法总结： 1. “there be”句型表示“某地有某物”，其中“be”动词的形式要根据其后所接名词的单复数来决定。 2. 当名词是单数或不可数名词时，用“there is”；当名词是复数时，用“there are”。 3. 否定句在“be”动词后加“not”；疑问句将“be”动词提到句首。 练习巩固： 用“there is/there are”填空： 1. ________ a pen and two pencils on the desk. 2. ________ some apples in the basket. 3. ________ any water in the bottle? 4. ________ no books on the shelf.
