Can; help 解析：can提前构成一般疑问句，动词用原形。 3. What should; do 解析：对动作提问用what，should提前，do代替原行为。 4. Could; eat some; Yes; could 解析：could委婉请求，疑问句保留some；肯定回答用could。 5. or get 解析：选择疑问句or连接两个选项，should后用动词原形。 6. the matter 解析：What’s wrong = What’s the matter with you。 7. aren’t supposed to 解析：shouldn’t = be not supposed to do；主语you，be动词用aren’t。 8. Does; have 解析：have为实义动词，主语he三单，助动词does，have变回原形。 9. rather than 解析：instead of = rather than 而不是。 10. If 解析：祈使句+or 转换为if条件状语从句。 11. mustn’t 解析：must否定mustn’t，意为禁止。 12. strong enough 解析：too…to…= not +adj.+enough to do。weak对应反义词strong。 13. What 解析：对句子主语（事件）提问用What。 14.

Protect 解析：这是祈使句。祈使句以动词原形开头，表示劝告；protect 是备选动词，protect your eyes保护你的眼睛；位于句首，首字母必须大写 → Protect。 3. rest 解析：should 属于情态动词，语法规则：情态动词后面必须接动词原形。rest 作动词意为 “使…… 休息”；rest your eyes让眼睛休息，因此直接填动词原形 rest，不需要变形。 4. could 解析：could 为情态动词，无词形变化，用来提出委婉建议，含义 “可以”。句意：此外，你可以调节屏幕亮度来适应周围的环境。 5. shouldn’t 解析：shouldn’t（=should not）情态动词否定形式，无变形。根据生活常识 “过马路不应该看手机”，表达不应当做的事，填 shouldn’t。 6. yourself 解析：考查反身代词。固定搭配 hurt oneself 伤到自己；句子主语是 you（你），第二人称单数，对应反身代词 yourself。 7. themselves 解析：考查反身代词。主语 Some students（一些学生），相当于人称代词 they；protect oneself保护自己；they 对应的反身代词是 themselves。备选词直接提供 themselves，无需变形。句意：他们不知道如何保护自己远离不良信息。 8. watching 解析：instead of 是介词短语，介词 of 后面，如果接动词，动词必须变为动名词doing 形式。 备选词 watch（观看），变动名词：watch → watching；watch videos看视频。句意：而不是一直看视频。 9. itself 解析：反身代词作同位语，用来加强语气，含义 “本身”。the phone 是事物、单数，对应反身代词 itself。The phone itself手机本身。备选词已有 itself，无需变形。 10. ourselves 解析：need to control oneself 控制某人自己；本句主语是 we（我们），we 对应的反身代词是 ourselves。 学科网（北京）股份有限公司 $
