Q 答案详解
一、1. B 种子是无意中粘到衣服上的，所以用“stuck”表示粘附。而“put”（放）和“packed”（打包）都是有意识的动作，不符合语境。故选 B。
2. B 后文提到“他花了很长时间才弄掉种子”，这说明这个过程很困难，所以选“difficult”。而“easy”（容易的）和“fast”（快的）都不符合语境。故选 B。
3. A 乔治想模仿种子上钩子的结构来发明东西，所以用“copy”表示模仿、复制。而“receive”（收到）和“repeat”（重复）不符合逻辑。故选 A。
4. B Velcro 用于防止物品在宇宙飞船中漂浮。所以用“prevent ... from”这一常见搭配，表示“阻止……（做某事）”。而“make”（使）和“have”（有）不符合语法和语义。故选 B。
5. C Velcro 在日常生活中很实用，所以用“helpful”表示有用。而“famous”（著名的）和“pleasant”（令人愉快的）不符合语境。故选 C。
二、1. B 根据短文提到的内容，“George de Mestral, a Swiss engineer”，乔治·德·梅斯特拉尔是一位瑞士工程师。故选 B。
2. A 短文指出“There were many tiny hooks on the seeds.”，正是这些小钩子让种子能够粘附在衣服上。故选 A。
3. B 乔治通过观察种子上的小钩子发明了 Velcro，这种模仿自然现象来创造发明的方式属于仿生学范畴。短文中提到他“copy this idea”，即模仿种子的钩子结构，因此选项 B 为正确选项。故选 B。
