The Dog and the Shadow 狗和它的影子
A DOG, crossing a bridge over a stream with a piece of flesh in his mouth, saw his own shadow in the water and took it for that of another Dog, with a piece of meat double his own in size. He immediately let go of his own, and fiercely attacked the other Dog to get his larger piece from him. He thus lost both: that which he grasped at in the water, because it was a shadow; and his own, because the stream swept it away.

Rewrite the sentences a required.（按要求改写句子）
16．Forests are very important because they provide food for animals. (对画线部分提问)
_____________ _______________ forests very important
17．The sun gives us heat and light.（保持原句意思基本不变）
We _______________ heat and light _______________ the sun.
18．We cut down trees to make furniture and paper.（对画线部分提问）
_____ _______ we cut down trees
19．People use wool for making clothes. （保持原句意思基本不变）
People use wool _______ ________ clothes.
【答案】16． Why are
17． get from
18． Why do
19． to make
【解析】
16．题目要求对画线部分提问。原句为Forests are very important because they provide food for animals。根据句子结构，画线部分为连词because引导的原因状语从句，表示直接的原因或理由，常用于回答why引导的特殊疑问句。故问句应用why开头的特殊疑问句，且主语forests为复数形式，be动词应用are，故应填(1). Why (2). are。
17．题目要求保持原句意思基本不变。原句为The sun gives us heat and light。根据句子结构，原句主语为The sun，句意为“太阳给了我们光和热”。改写后的句子主语为We，从原句的动作承受者变为了动作的施动者，故应对谓语动词进行替换，由原句的“太阳给予”转换为“从太阳那里得到……”。get … from意为“从……得到……”，符合句意，故应填(1). get (2). from。
18．题目要求对画线部分提问。原句为We cut down trees to make furniture and paper。根据句子结构，画线部分为不定式作状语，表目的，对此部分进行提问应用特殊疑问词why。改写句子谓语cut为实义动词，故前面应用助动词do，故应填(1). Why (2). do。
19．题目要求保持原句意思基本不变。原句为People use wool for making clothes。对原句进行同义句转换，只需对句中use sth. for doing sth.结构进行同义替换即可。use sth. for doing sth. = use sth. to do sth.，意为“使用某物做某事”，符合题意，故应填(1). to (2). make。
【点睛】
本题1、3小题解题方法一致。1、3小题题目要求对画线部分进行提问，此类型题问句通常为特殊疑问句，所以确定特殊疑问词是关键。1、3小题画线部分在句中作状语，表原因和目的，故改为特殊疑问句时应用特殊疑问词why。
