修辭手法
常見錯誤
What are common mistakes with "Device"?Which "Device" sentences look correct but are wrong?
×I need a new electronic device.
✓I need a new electronic device.
雖然 'device' 是可數名詞，但此句本身文法正確。常見錯誤是誤以為 'device' 不可數而省略冠詞，例如說成 'I need new electronic device.'。正確用法是：單數時必須有冠詞 (a/the) 或所有格 (my/this)。
×We need to device a new strategy.
✓We need to devise a new strategy.
'device' 是名詞（裝置），而 'devise' 是動詞（設計、想出）。兩者發音相似但詞性與意思完全不同，切勿混淆。
×My new kitchen device can chop and blend.
✓My new kitchen gadget can chop and blend.
'device' 通常指功能較特定或複雜的裝置（尤其是電子或機械的），而 'gadget' 常指小巧、新奇或便利的小工具或小玩意。廚房用的多功能小工具更常用 'gadget' 或 'appliance'。
×All the device in the lab are connected.
✓All the devices in the lab are connected.
'device' 的複數形式是規則變化，直接加 's' 變成 'devices'。當主詞為複數時，動詞也必須使用複數形式。
×This is a device for measure temperature.
✓This is a device for measuring temperature.
介系詞 'for' 後面應接名詞或動名詞 (V-ing)，表示用途。不可接動詞原形。
