答案
电影院座位够;栅栏需要20米;英语选择:1.B 2.B 3.B 4.C 5.C 6.B 7.A 8.B 9.C 10.C;写作示例:My good friend is Amy. She is 9 years old. She likes drawing pictures. She is good at dancing. We often play together.
解析
1. 电影院座位问题:先计算电影院总座位数,排数×每排座位数=21×26=546(个),将总座位数与学生人数500比较,546>500,所以能坐下。2. 栅栏问题:花园为长方形,长10m,宽8m,栅栏需围花园三边(减去房子占的5m),再减去1m的门,计算得:10 + 8×2 -5 -1=20(米)。3. 英语选择填空:根据语法、词义逐一分析:1. 问句主语是you,回答用I,选B;2. 主语classmate是第三人称单数,like为动词原形,用doesn't,选B;3. 修饰名词name用形容词性物主代词her,选B;4. 描述苦味用taste,选C;5. 前后为转折关系用but,选C;6. 主语horse是第三人称单数,feel为动词,用does,选B;7. 表示“六月的第一天”用of,选A;8. 结合语境选your,选B;9. old以元音音素开头,用an,选C;10. friends为复数,用They are,选C。4. 写作部分:围绕朋友的身份、年龄、爱好等写5个符合要求的句子即可。
