常见错误

❌ 错误:The rate of the car is very fast.
✓ 正确:The speed of the car is very high.

rate 表示“速度”时多指比率或频率(如心率),不直接描述物体运动快慢;应用 speed 表示具体速度。

❌ 错误:I rate him as a good friend.
✓ 正确:I consider him a good friend.

rate 作“认为”时侧重评估等级或排名,不用于一般的人际关系判断;consider 更自然表示“认为”。

近义词辨析

speed

speed 强调物体移动的快慢,而 rate 多指比率、频率或变化速度(如增长率)。

The car's speed is 60 mph. (具体速度) vs. The unemployment rate is rising. (比率)

evaluate

evaluate 是正式评估,强调全面分析;rate 更侧重打分、排名或简单评价。

We need to evaluate the project's overall impact. (全面评估) vs. Customers rate the service 5 stars. (打分)
