二、单句改错
1.(2013·新课标，5)This custom soon became another meal of day.
答案：day前加the day此处意为“时期，时代”，特指某一时期，故用定冠词the。
2.(2013·四川，7)The teacher was angry because we had same answers in the test.
答案：same前加the same意为“相同的，同样的”，其前必须有定冠词the。
3.(2013·浙江，7)Tomorrow is first day of school.
答案：first前加the或my 表示顺序的序数词前要加定冠词或物主代词、名词所有格等限定词。
4.(2012·浙江，10)As a result, nobody knew truth.
答案：truth前加the 特指前面提到的事情的真相，因此用定冠词the。
5.(2014·新课标)As result, the plants are growing everywhere.
答案：As后加a as a result意为“结果，因此”，是固定短语。
6.(2015·新课标)Now I'm living in a city，but I miss my home in countryside.
答案：countryside前加the in the countryside意为“在农村”，是固定短语。
7.(2015·云南昆明质检)I think it good habit that in our spare time we read more books of great use.
答案：good前加a habit意为“习惯”，是可数名词，此处为泛指，故用不定冠词a修饰。
8.(2015·甘肃武威一模)Three years ago I failed an important exam in my life and became a student in a ordinary school.
答案：第二个a→an ordinary是以元音音素开头的形容词，故其前应用不定冠词an。
9.(2015·辽宁葫芦岛一模)Last Sunday I saw a worst storm in years. It came suddenly and went on for over three hours.
答案：a→the 根据in years可知，此处表示“最严重的暴风雨”，形容词最高级前应加定冠词the。
10.(2014·河南开封二模)When children are ill, I try my best to take a good care of them.
答案：去掉good前的a take good care of...为固定搭配，意为“精心照顾……”，care前不加冠词。
三、语法填空

A journal __3__(call)Annals of Family Medicine recently published an article，__4__ called for doctors to start treating children's contact to secondhand smoke as abuse.In that case，contact to secondhand smoke would be viewed much like physical abuse or neglect.The author of the article，Dr.Adam Goldstein，is __5__ professor at University of North Carolina School of Medicine.He says secondhand smoke __6__(cause)many diseases in children.

1.______ 2.______ 3.______ 4.______ 5.______
6.______ 7.______ 8.______ 9.______ 10.______
答案：
文章大意：吸二手烟的危害显而易见。人们应该对此多加关注。
1.However 考查连词。前后句之间是转折关系， 空后有逗号，所以填however。
2.regularly 考查形容词与副词。此处修饰动词smoke，故用副词。
3.called 考查非谓语动词。journal与call之间构成逻辑上的动宾关系，所以用过去分词。
4.which 考查定语从句。从句中缺少主语，所以填关系代词;先行词是article，所以填which或that;再由逗号可知，此处是非限制性定语从句，所以填which而非that。
5.a 考查冠词。Dr.Adam Goldstein是University of North Carolina School of Medicine的一位教授，此处表泛指，所以填不定冠词。
6.causes 考查时态。此处是该教授说的研究结果，所以具有真理性，故用一般现在时;主语是secondhand smoke，所以用单数第三人称。
7.without 考查介词。此处是两组人员比较，一组是父母吸烟的，一组是父母不吸烟的。所以填without，与后一句中的with反义对应。
8.more 考查比较级。此处与前面的smaller照应，所以使用比较级。
9.the 考查冠词。have the right to do sth.有做某事的权利。
10.until/before 考查连词。句意：直到烟草公司关闭我们才会停止战斗。
四、短文改错
(2015·日照市二模)
My grandparents live in the countryside.They keep a dog calling Ah Bao.One day my grandparents go to work in the fields，taking along my little brother and Ah Bao.My brother and Ah Bao came to a river nearby and enjoyed himself. My brother was trying to catch a butterfly while he fell into a river.Ah Bao barked and immediate jumped into a water.Hearing about him barking，my grandparents hurried there and saw Ah Bao swimming towards the bank carrying my brother. Ah Bao did all he could save my little brother，that moved all the people present.Everyone praised Ah Bao for his brave and kindness.
答案：
My grandparents live in the countryside.They keep a dog Ah Bao.One day my grandparents to work in the fields，taking along my little brother and Ah Bao.My brother and Ah Bao came to a river nearby and enjoyed . My brother was trying to catch a butterfly he fell into a river.Ah Bao barked and jumped into water.Hearing about him barking，my grandparents hurried there and saw Ah Bao swimming towards the bank carrying my brother. Ah Bao did all he could save my little brother， moved all the people present.Everyone praised Ah Bao for his and kindness.
解析：
第一处：calling→called 考查非谓语动词。根据dog是call的动作承受者，应用过去分词作定语。
第二处：go→went 考查时态。由全文可知，应该使用一般过去时。
第三处：himself→themselves 考查代词。根据该句的主语my brother and Ah Bao判断反身代词应用themselves。
第四处：while→when 考查连词。be doing...when...是固定句式，意为“正在做……(就在这时)突然……”。
第五处：immediate→immediately 考查形容词与副词。修饰动词jumped应该用副词。
第六处：a→the 考查冠词。river在前文已经提到，应用定冠词表特指。
第七处：去掉about 考查介词。hear听到;hear about听说。此处是hear sb doing听到某人正在做某事。
第八处：could后加to 考查非谓语动词。句意：为了救那个小男孩，Ah Bao尽了最大的努力。由句意可知，此处使用不定式作目的状语。
第九处：that→which 考查定语从句。此处是非限制性定语从句，不能用that引导。
第十处：brave→bravery 考查名词。分析句子， his后应加名词形式，与and后的kindness并列。
