Studio Classroom- August 28- [How Stuff Works] How Golf Greens Work

【Grammar on the Go】

• 本日討論例句：
  A backhoe digs a nice big hole the size of the green.
• "the size of the green" is describing the hole.
  How big is the hole? It's the size of the green.
• Having the adjective phrase "the size of the green" immediately after a noun is quick and effective way to let people know how big or small the thing is.
• ex:
  1. Mr.Simmons has a guard dog outside his house. The guard dog is as big as a bear.
  We can say: Mr.Simmons has a guard dog the size of a bear outside his house.
  2. The actress wore a ring with a big stone. The stone was about the size of a ping-pong ball.
  We can say: The actress wore a ring with a stone the size of a ping-pong ball.
• There are other ways to describe things other than just talking about sizes.

【Chat Room】

• 本日討論重點例句：
  A "backhoe" is used to dig "a nice big hole" the size of the green.
• both engineering vehicles:
  ┌backhoe：怪手，挖土機
  ---A backhoe has an arm in the bucket which can be used for digging.
  └bulldozer：推土機(車頭裝有鐵板)
  ---A bulldozer is a large and powerful crawler tractor that is usually equipped with a front blade that is used to move large amounts of soil, rubble and rock.
• a "nice" big hole
  - That's a different definition of "nice", the size be likeable or pleasing, '"nice" can be used for emphasis. 此處"nice"用來加強原本的含意，表示"非常的"
  So, a nice big hole is just a really big hole! 一個"非常大"的洞
  ex:
  1. That's a nice mess! 真是一團糟!
  2. There is a big cut on your hand. I might say: That's a nice cut! 很深的傷口
