考點分析
"英語說明文",顧名思義,就是一種以"說明、解釋"為主要表達(dá)方式的英語文體。它是對客觀事物的性狀、特點、功能和用途等作科學(xué)解說的。它既不像故事那樣重在情節(jié)的敘述和描寫,也不像議論文那樣,重在闡明主張和論點論據(jù);更不像科幻作品那樣富于想象和虛構(gòu)夸張。說明文是通過解說事物、闡明事理,使人們增長知識和技能。說明文是高考英語閱讀理解題中的重點內(nèi)容之一。說明文具有與自己特點相適應(yīng)的說明方法,因此說明文結(jié)構(gòu)復(fù)雜,專業(yè)術(shù)語多,易于拉開考生分?jǐn)?shù)檔次,便于高校分層次選拔人才。然而對于考生來說說明文抽象度高,解題難度大。高考對說明文的考查多為科普知識,動植物特性、自然現(xiàn)象和新產(chǎn)品、新工藝介紹以及人文地理、風(fēng)土人情等方面的說明文,文中解釋性、定義性、說明性的句子居多。因此考生要掌握說明文的命題特點,敘述方式,以冷靜的心態(tài)閱讀原文,重點突破長句結(jié)構(gòu)特點和邏輯關(guān)系,以便對其做出準(zhǔn)確的語意理解。
知識梳理
說明文閱讀理解的特征
一般說來,英語說明文與其他文體一樣,文章所涉及的內(nèi)容不外乎以下幾個方面,即wh → what → when → where → hw → why。
1. wh:問的是這篇文章的主體是誰?(即所要說明和描述的人或事物)
2. what:問的是主體做了什么事情?(即主體表現(xiàn)出的特性、功能和用途)
3. when和where:是在何時何地發(fā)生的?(即何時何地所表現(xiàn)出的特性、功能和用途)
4. hw:通過什么方式表現(xiàn)出來的?
5. why:這種特性功能用途的原因是什么?
做說明文閱讀理解題的時候,一定要記住上面的wh-wrd。邊閱讀,邊搜記,牢記要點,把握全文。

When yu think f the Arctic (北極), yu imagine an icy land f pure white snw. Others imagine it as the last really clean place left n earth. We have plluted the deepest ceans with plastic rubbish. “And nw”, CNN says, “It’s the Arctic’s turn.”

The blue whale (鯨) is the largest animal alive tday. And ne f these whales has been caught making a big jurney thrugh the Suth Pacific. The whale was first recrded near the Galapags Islands, west f Csta Rica. Years later, that same whale was phtgraphed ff the cast f Chile in Suth America, a new study reprts. The tw places are separated by abut 5,200 kilmeters. That means the whale, nicknamed Isabella, swam farther than the distance between New Yrk and Ls Angeles.
Blue whales are fund in all the wrld’s ceans but live in deep waters. S there are few places where they can be fund easily. What’s mre, they were nearly driven by whaling a century ag. Ppulatins are increasing. But because there are s few f the animals, they are still cnsidered endangered.
One blue whale may lk like any ther t the untrained eye. But each animal has special spts (斑點). “We use thse spts as the fingerprints f blue whales,” Trres Flrez says. T make the cmparisn jb easier, scientists fcus n the area arund a whale’s drsal fin (鰭), which is n its back. “Cmparing thse spts we are able t tell if a whale is the same whale we saw in different places r if the same whale is seen during different years in the same place,” he says.
Isabella is prbably nt the nly blue whale t travel s far, the researchers say. Members f her ppulatin likely migrate regularly frm Chile t the Galapags. In summer mnths, Trres Flrez ntes, waters in the far suthern Pacific are laded with krill, but that fd disappears in winter. That’s when the whales travel nrth t warm, trpical (熱帶的) waters near the Galapags. There, instead f feeding, the whales prduce babies. Scientists dn’t yet knw why whales prefer t prduce babies in trpical lcatins. But the cean there may be warmer and calmer and have fewer killer whales that wuld feed n baby blue whales, Trres Flrez says.
11.What can we infer abut blue whales in Paragraph 2?
A.They are n lnger at the risk f dying ut.
B.It’s difficult fr scientists t study them.
C.They can’t live well in a new envirnment.
D.It is cmmn fr peple t see them wrldwide.
12.What is Paragraph 3 mainly abut?

A.there is enugh fd fr baby blue whales
B.they dn’t have enemies there
C.it’s easy fr them t find a mate there
D.it’s easy fr baby blue whales t remain alive there
