30秒搞懂 英文的比較 什麼跟什麼一樣 as…as 用法

as xxx as 是一個常用的句型,用來表示英文的比較,例如兩個事物或人之間、或什麼跟什麼之間、或數學上的比較。例如:

  • The eraser is as long as the beads.
  • The broom is as tall as the tree.
  • The key is as heavy as the rock.

上面這張圖片我本來第一眼還覺得沒什麼問題,看第二次之後才發現原來是要寫:

  1. The eraser is as long as seven beads.
  2. The broom is as long as seven straws.
  3. The key is as long as five pins.
  4. The nail is as long as seven screws.

  1. 用來表示兩個數值相等。例如:
