BLooking out of my window today reminded me of another day just like this one,a day when I wassearching for a special blue bird.I thought it had been talking to my grandmother about me.One day grandmother asked me to buy some bread.On the way home I gave my bread to a blackdog.I really wanted to keep her but I knew my mother would not allow.An idea occurred to me.I got to our back gate,carefully dug a hole under the fence,and left therest of the bread right at the hole.Then from the front door I went down the drive and through to thebackyard.I got there just in time.She was trying to reach the bread at the hole.I held her front paws andpulled her through.She ate up the bread and I was delighted that my idea had worked.When I got inside,I told my grandmother that my bread was eaten by a stray dog.I was verypleased with myself for not having to lie.We suddenly heard scratching coming from the back door.Seeing her,grandmother asked me,"Where did that come from?""She must have come in under thegate."I pointed out the hole under the back gate.Grandmother told me she thought it was I who broughtthe dog home.I looked at my grandmother's face and asked,"How did you know?"She said,"A littlebird told me,a little blue bird told me.”I reminded her I had not told a lie..She grinned(咧嘴笑)andsaid,"No you did not lie.But the truth you told was not the whole story either."I spent most of that summer making sure the blue birds stayed out of the yard.I remember watchinggrandmother giggling(咯咯笑)a little as she watched me..Years later I found out that grandmother had been looking out of the breakfast room window andwatched me dig the hole,run back into the yard and pull the dog through.She and my mother laughedabout it.Anyway,we kept the dog (even after she delivered 13 puppies)until she passed away withsnow-white on her snout and around her eyes.24.How did the dog get into the house?A.From the hole under the fence.B.From the bakery at the back door.C.From the front door and the drive.D.From the breakfast room window.25.What does the underlined word "that"in paragraph 4 refer to?A.The bird.B.The scratching noise.C.The dog.D.The hole.26.Why did grandmother grin?A.Because she knew the truthB.Because she once talked to the bird.C.Because she thought I told the truth.D.Because she loved the dog too.27.How did the writer feel about keeping the dog?A.Frightened and puzzled.B.Concerned and happy.C.Tolerant and sympathetic.D.Delighted and carefree.CHave you ever found picking out the face of a friend in a group photo is sometimes hard,especiallywhen everyone crowds together?In the same way,it can also be hard to read a passage of text when theletters are too close together.In fact,a new study shows that spacing the letters farther apart can help宣城市高三英语试卷第4页（共10页）

第二节主题语境：人与自然一一环境保护本文是说明文。文章介绍了中国对亚洲象的保护情况。56.for。考查介词。根据The Xishuangbanna National Nature Reserve和its biodiversity可知，西双版纳国家级自然保护区以它的生物多样性闻名，故填介词for。57.to survive。考查动词不定式。fail to do sth是固定搭配，意为“未能做到某事”。58.which。考查关系代词。设空处引导非限制性定语从句，修饰The Asian elephants,且在从句中作主语，故填which。59.mainly。考查副词。设空处修饰谓语动词，故填副词mainly.60.the。考查冠词。此处的species表特指，指代上句中提到的亚洲象，故其前用the。61.professional。考查形容词。设空处作定语修饰team,故填professional,意为“专业的”。62.saved。考查动词-ed形式。设空处作后置定语修饰elephants,.且save与elephants之间是逻辑上的动宾关系，故填saved。63.monitoring。.考查动词-ing形式。设空处作伴随状语，caregivers与monitor之间是逻辑上的主谓关系，且monitor表示的动作与谓语动作同时发生，故填monitoring。本句中与设空处并列的bringing也提示了答案。64.is。考查主谓一致。从句作主语时，谓语需用单数形式，且此处描述客观情况，故填is。65.has risen。考查现在完成时。根据in the last30 years可知，rise所表示的动作开始于过去且对现在有影响，且主语中心词是population,故填has risen。
