常见错误

❌ 错误:I saw a ray light in the dark room.
✓ 正确:I saw a ray of light in the dark room.

错误在于缺少介词 of。ray 表示“一缕”时,必须与 of 连用,构成固定搭配 a ray of light。

❌ 错误:The sun rays are very hot today.
✓ 正确:The sun's rays are very hot today.

错误在于名词所有格使用不当。在英语中,表示所属关系时,常用 's 或 of,这里应改为 sun's rays 或 rays of the sun 以更自然。
