常见错误

❌ 错误:There are many insect in the forest.
✓ 正确:There are many insects in the forest.

insect 是可数名词,表示复数时需加 -s。中文学习者常忽略单复数变化,导致语法错误。

❌ 错误:I don't like insect because it is dirty.
✓ 正确:I don't like insects because they are dirty.

当泛指昆虫类别时,应用复数 insects,代词也需一致用 they。单数 insect 通常指特定一只昆虫,易造成指代不清。
