篇章結構題
此類題目能全面地、深層次地考查考生的閱讀理解能力。
[解題技巧] 把脈絡看結構
篇章結構題主要是針對文章的整體篇章結構或某一段落的展開層次所設置的問題。高考對篇章結構的考查主要涉及兩個層次：一是按段落的組織方法理解文章的結構；二是按寫作手法(論證方法)理解篇章的結構。設問形式常有：
(1)Which f the fllwing shws the develpment f ideas in this passage?
(2)Which f the fllwing shws the rganizatin/structure f the (whle) passage?
因此這類題的解題方法也分為兩種：
注意：
1．文章的段落組織通常采用“總—分；分—總；總—分—總”的框架。
2．內容的展開則常用以下手法：
(1)時間順序：按時間先后順序說明某一事物的發(fā)展情況。
(2)空間順序：按照事物的空間結構順序進行描寫或說明。
(3)例證關系：所列舉的事物用來論證觀點，通常是數據、事例等。
(4)對比或類比關系：這類文章通常以對比各事物之間的共同點或差異為主。

Whales，seals and sme penguins have thick fat layers.This is a little like cvering yurself in a blanket，but n the inside.In sme animals this is even further imprved，with the animals selectively able t reduce the bld flw t the fat layers.The further the bld is frm the skin surface，the less the heat is lst.Fat layers can als be used as energy reserves，fr example，male elephant seals can live ff their fat reserves during summer.
The term “extremities” is used t mean any bdy part that is furthest away frm the main bdy.In humans，ur hands and feet cunt as “extremities”．These are ften the first places t feel cld in winter.The same applies t animals.Emperr penguins have very small bills(喙) and feet，which means less bld is required t these areas.
