Question

18．When you take a walk in any of the cities in the West，you often see a lot of people walking dogs．（61）It is still true that a dog is （62）the most useful（use） and faithful animal in the world．（63）But the reasons why people keep a dog （64）have changed（change）．In the old days people used to train dogs to protect themselves against animal attacks．And later they came （65）to realize（realize） that a dog was not only useful for protection but willing to obey his master．For example，when people used dogs for hunting，the dogs would not eat （66）whatthey caught without （67）permission（permit）．But now people in the city need not protect （68）themselves（they） against attacks of animals．
Why do they keep dogs，then？Some people keep dogs to protect themselves from robbery．But the most important reason is for companionship．For （69）achild，a dog is his best friend when he has no friends to play with．For a young couple，a dog is their child when they have （70）nochildren．For old couples，a dog is also their child when their real children have grown up．So the main reason why people keep dogs has changed from protection to friendship．

Answer 1

分析 本文主要介紹狗是世界上最有用和最忠實(shí)的動(dòng)物．但現(xiàn)在人們養(yǎng)狗的原因已經(jīng)變了．在過(guò)去，養(yǎng)狗是為了保護(hù)他們自己免受動(dòng)物的攻擊，狗不僅有用而且愿意服從主人的命令．現(xiàn)在，養(yǎng)狗最主要的原因是為陪伴．

解答 61．It  考查it的用法．It在這里作形式主語(yǔ)，指代真正的主語(yǔ)"that the dog is the most useful…"．
62．the most useful 考查形容詞最高級(jí)．根據(jù)句意：狗是世界上最有用和最忠實(shí)的動(dòng)物．用形容詞最高級(jí)．
63．But 考查連詞．前后兩個(gè)分句之間是轉(zhuǎn)折關(guān)系，用連詞but．
64．have changed  考查動(dòng)詞的時(shí)態(tài)．根據(jù)句意：人們養(yǎng)狗的原因已經(jīng)變了．此處用現(xiàn)在完成時(shí)表示結(jié)果．
65．to realize 考查非謂語(yǔ)動(dòng)詞的用法．根據(jù)句意：后來(lái)他們逐漸認(rèn)識(shí)到…．come to realize意為"認(rèn)識(shí)到，開(kāi)始意識(shí)到"，是固定搭配．
66．what 考查連詞．由動(dòng)詞 eat和caught缺少賓語(yǔ)可以判斷此處需用what引導(dǎo)賓語(yǔ)從句．
67．permission 考查名詞．without是介詞，后接名詞作其賓語(yǔ)．
68．themselves 考查代詞．根據(jù)句意：現(xiàn)在城市中的人們不必保護(hù)他們自己免受動(dòng)物的攻擊．用反身代詞themselves．
69．a(chǎn)  考查不定冠詞的用法．此處用不定冠詞表示泛指，意為"對(duì)于孩子來(lái)說(shuō)，當(dāng)他沒(méi)有朋友一起玩時(shí)狗是他最好的朋友"．
70．no 考查形容詞．根據(jù)句意：當(dāng)他們沒(méi)有孩子時(shí)．用形容詞no．

點(diǎn)評(píng) 在一篇200詞左右的語(yǔ)篇（短文或?qū)υ挘┲辛舫?0處空白，部分空白的后面給出單詞的基本形式，要求考生根據(jù)上下文填寫空白處所需的內(nèi)容或所提供單詞的正確形式，所填寫詞語(yǔ)不得多于3個(gè)單詞．要做好語(yǔ)法填空題，理解短文是解題的前提，扎實(shí)的詞匯、句型和語(yǔ)法知識(shí)是基礎(chǔ)，英語(yǔ)國(guó)家的背景知識(shí)是必要的補(bǔ)充．考生須靈活運(yùn)用語(yǔ)法知識(shí)，如單詞詞性、單詞時(shí)態(tài)、名詞單復(fù)數(shù)、連接詞、代詞、冠詞等判斷各空白處應(yīng)填寫的內(nèi)容．答完后，還要通讀全文，核對(duì)所填單詞形式是否正確，是否符合語(yǔ)境．
