1．指示代詞(1)定義：指示代詞是用來指示或標識人或事物代詞。指示代詞表示“這個”、“那個”、“這些”、“那些”等含義。指示代詞有名詞和限定詞功效。常見指示代詞有________，________，________，________等。thisthatthese

those4/24(2)使用方法：①指示代詞可在句中作主語、賓語和定語。如：________isadesk.這是一張書桌。(作主語)________boyismyfriend.這個男孩是我朋友。(作定語)②this和these表示所指人或物距離說話人比較近，而that和those表示所指人或物距離說話人比較遠。如：________isanorangeand________isanapple.這是一個橙子，那是一個蘋果。ThisTheseThisthat5/24③從數上來看，this和that指單數，these和those指復數。如：________ismymother.這是我媽媽。________aremyparents.這是我父母。④this和that用作電話用語時，this指自己，而that指對方。如：Hello,________isMary.Is________Xiaoli?你好！我是瑪麗。你是小麗嗎？ThisThesethisthat6/24⑤當指示代詞在疑問句中作主語時，其答句主語改變：this,that→it;these,those→they。如：—Is________abook？這是一本書嗎？—Yes,________is.是，它是?！狝re________yourfriends?那些是你朋友嗎？—Yes,________are.是，他們是。thisitthosethey7/242．單數句與復數句轉換(1)將單數句中指示代詞、人稱代詞、名詞及be動詞等變為復數形式This/Thatisaruler.→These/________arerulers.SheisinChina.→TheyareinChina.I'maboy.→We________________．Thoseareboys8/24(2)將單數句中不定冠詞a,an去掉(一些固定搭配除外)。Itisanapple.→________________apples.Thatisapencil.→________________pencils.(3)單數句中形容詞、定冠詞、副詞、疑問詞、介詞等保持不變。Thepenisred.→Thepensarered.Whatcoloristhejacket?→Whatcolorarethejackets?TheyareareThose9/24【注意】名詞作定語時，普通用單數形式，被修飾名詞變復數時，普通情況下，作定語用名詞不需要變為復數形式，但由man或woman作定語修飾名詞變成復數時，兩部分皆要變為復數形式。如：Thatisanorangequilt.→Thoseare________________．
