A flying car。2. Four wheels and two wings。3. By voice / Shout “Fly!”。4. Traffic jams。5. B。6. No. It is an idea, and some details still need testing. 说明功能构想不等于证明现实产品已安全可用。 二 示例：The users are students. The problem happens when they bring wet umbrellas into the classroom. 允许任何具体、合理的校园或家庭需要。 三 设计示例：Umbrella Home；students；a narrow stand with a tray；holds umbrellas upright；a removable tray catches water；keeps the floor dry；needs space near the door。不强求所有学生选相同物品。 四 B。它写出了部件、动作与结果。改写示例：It keeps small things in separate pockets, so students can find them quickly. 用读者能想象的用途替代空泛赞美。 参考习作 96词 Umbrella Home My invention is Umbrella Home, a small stand for wet umbrellas. It is designed for students on rainy days. It has six narrow spaces and a tray at the bottom. First, put your umbrella into an empty space. Water then runs into the tray instead of onto the floor. After school, take out the tray and empty it. The stand would keep our classroom entrance dry and tidy. However, it can hold only six umbrellas. I would make a larger version for our class and test whether it stays steady when all the spaces are full. 评价建议 共10分 维度 得分依据 内容 4分 名称与用户1分；外形1分；用法1分；好处及局限1分。 组织 2分 顺序清楚1分；句子之间衔接自然1分。 语言 3分 词语基本准确1分；句子基本完整1分；拼写标点基本正确1分。 修改 1分 回应一个读者问题，作出实质性修改。 第 页 学科网（北京）股份有限公司 $
