Ⅰ.阅读理解

When doctors urge overweight kids to pick up more activities,reading probably isn’t what they have in mind.Y et a new study by fatness researchers at Duke University finds that the simple act of reading—depending on the choice of material—can cause weight loss in teenage girls.

The study’s experimental group included 31 fat girls aged 9 to 13,who took part in the Healthy Lifestyles Program at Duke Children’s Hospital.The girls read a novel called Lake Rescue,whose protagonist (主人公) is an overweight teenager who struggles with low self-esteem,feelings of loneliness and teasing because of her size.A group of 33 girls read a different book called Charlotte in Paris,which did not have an overweight character,and another group of 17 girls read neither book.

At the end of the six-month experiment,all the girls who read books had lost weight,but the

girls who read Lake Rescue lost more.They lowered their body mass index (BMI) by 0.71,compared with 0.33 in the Charlotte group,an average 0.05 increase among the nonreaders.

The idea behind the study,says Dr Sarah Armstrong,director of Healthy Lifestyles,was to find a way to encourage the girls without adopting the restrictive and often authoritative voice of so many other nutrition and diet https://www.wendangku.net/doc/6816876121.html,ke Rescue was the perfect instrument,says Armstrong;it presents a likable character to whom the girls could relate and whom they could learn from.As the book progresses,its protagonist learns to make healthier lifestyle choices and finds an advisor to help keep her on track.Armstrong says,“She learns that she can become healthier,and the ‘I can do it’ feeling resonates (产生共鸣) with the teenage girls.”1.What’s the main idea of the passage?

A.There are different ways to help overweight kids lose weight.

B.Lifestyle is important for kids.

C.Lake Rescue is the perfect weight-losing instrument.

D.Reading can help kids lose weight.

2.How many girls took part in the experiment?

A.31. B.33. C.64. D.81.

3.What does the underlined word “She” in the last paragraph refer to?

A.Armstrong.

B.The protagonist in Lake Rescue.

C.A character in Charlotte in Paris.

D.A girl in the first group.

4.According to the passage we can know that .

A.overweight girls are living unhappily

B.reading is the best way to lose weight

C.different reading materials play different roles in losing weight

D.people will become fat if they don’t read

5.In which part of a newspaper can we read the above passage?

A.Education. B.Entertainment.

C.Health. D.Advertisement.

Ⅱ.读写任务

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

Forming good study habits is a great start on a path to success.Even small changes can make a big difference and,over time,will change not only your approach toward studying and organizing but your overall outlook on school and work.

Having effective study habits creates a more efficient academic environment.Planning your study schedule in advance and faithfully sticking to it saves time.Even giving consideration to small details makes a difference.Developing an efficient study plan can make your academic life go much more smoothly.

When you have good study habits,you tend to be less stressed.Students who are anxious on exam day are typically those who came unprepared.Students who organize their lives and stick to their study schedules are confident and relaxed at test-taking time.

Regardless of whether you are setting a good example for classmates or for friends,showing good study habits can have a positive effect on those around you.Y our friends and classmates may turn to their own studies as you study.Y our roommates may be inspired to organize their own rooms and study plans.

英语简单句的结构

英语基本句型有五个:S+V,S+V+Cs,S+V+O,S+V+Oi+Od,S+V+Od+Co,其共有特征是主谓结构(S+V)。

一、(S+V)主谓结构(主语+不及物动词)

1.此句型中,“V”是不及物动词,后面无宾语,如:My right arm hurts.。但通常有后续成分或称状语(A),即S+V+A,如:

She lived happily.

The sun rises every morning.

2.在有些句子中,主语或谓语或某一部分可以省略,如:

Hope to see you again soon.(省略主语)

—Who called?

—Jane (did).(省略谓语)

二、(S+V+Cs)主系表结构(主语+系动词+主语补足语)

1.此句型中的“V”是连系动词,“Cs”是主语补足语,或称表语。充当主语补足语的有名词、代词、形容词、副词、数词、介词短语、动词-ing形式或-ed形式、不定式及名词性从句等,如:My first name is Bill.;Life is colorful.;Seeing is believing.;Our belief is that things will improve.。

2.常见的连系动词有下列几类:(1)表示“判断”:be;(2)表示“变得”、“成为”:become,come,go,fall,get,grow,prove,turn等;(3)表示“保持着某一状态”:hold,keep,lie,remain,rest,sit,stay等;(4)表示“看起来”、“好像”:appear,look,seem等;

(5)表示“实感”:feel,sound,taste,smell等。

She is a teacher and I am a doctor.

Spring comes and all trees turn green.

He stayed awake all night.

Y ou don’t look happy.What’s the matter?

Their plan sounds wonderful.

三、(S+V+O)主谓宾结构(主语+及物动词+宾语)

1.“V”是及物动词,后面需跟一个宾语,可充当宾语的有名词、代词、数词、不定式、v.-ing结构及名词性从句等,如:

I understand the program.

She asked to see the manager.

2.这种结构有时必须跟状语,意义才完整(即S+V+O+A),如:

We accepted their advice in buying a new car.

She completed the assignment just as the bell was ringing.

四、(S+V+Oi+Od)双宾语结构(主语+双宾动词+间接宾语+直接宾语)

1.此句型中的“V”称为双宾及物动词,其后需跟间接宾语“Oi”(通常指人)和直接宾语“Od”(通常指物或事)。

2.此类动词大都具有给予的意义,常见的有:allow,award,bring,buy,choose,fetch,find,get,give,hand,leave,lend,offer,owe,pass,pay,promise,recommend,refuse,render,return,sell,send,show,take,tell等,如:

I gave him the book.

I’ll return you the dictionary soon.

3.有时间接宾语可移至直接宾语之后,但要加相应的介词,如to,for,of等,试比较:Betty gave her daughter an apple.

→Betty gave an apple to her daughter.

Father bought him a bike.

→Father bought a bike for him.

He asked me a question.

→He asked a question of me.

五、(S+V+Od+Co)复合宾语结构(主语+宾补动词+宾语+宾语补语)

该句型中,谓语动词虽有宾语,但句子意义仍不完整,需加补语“Co”补足其意义。充当宾语补语的有名词、形容词、副词、介词短语、不定式短语及分词等,如:We found the house empty.

Our neighbors built their wall high.

常用的这类动词有:appoint,believe,call,catch,choose,consider,elect,fancy,feel,find,hear,imagine,judge,keep,leave,make,name,need,prefer,prove,

see,think,vote等。

By developing good study habits,you will work more efficiently and experiencing less stress in the learning process.Having good habits and skills can also influence those around you.

As for me,I benefit a lot from my good habits like getting up early to read English aloud,going over what I have learned before going to bed,and listening to some English programs every day.

In the past,I dared not speak English because I was poor in pronunciation.Thanks to my good habits,however,I have been making progress in my English speaking.Now I’m actively involved in the discussion in English classes,and also,I’m doing much better in English exams.

Therefore,I think it is of great significance to cultivate good study habits.When you have made a plan,stick to it for at least one week,no matter how hard it is.Then you may find it is not as difficult as it appeared.Besides,finding a partner to study together with is also a good way to keep you motivated.

第二章第5讲【2016化学大一轮步步高答案】解析

第5讲氧化还原反应的计算及方程式的配平 [考纲要求] 1.掌握常见氧化还原反应的配平和相关计算。2.能利用得失电子守恒原理进行相关计算。 考点一氧化还原反应方程式的配平方法 氧化还原反应的实质是反应过程中发生了电子转移,而氧化剂得电子总数(或元素化合价降低总数)必然等于还原剂失电子总数(或元素化合价升高总数),根据这一原则可以对氧化还原反应的化学方程式进行配平。 配平的步骤: (1)标好价:正确标出反应前后化合价有变化的元素的化合价。 (2)列变化:列出元素化合价升高和降低的数值。 (3)求总数:求元素化合价升高和降低的总数,确定氧化剂、还原剂、氧化产物、还原产物的化学计量数。 (4)配系数:用观察法配平其他各物质的化学计量数。 (5)细检查:利用“守恒”三原则(即质量守恒、得失电子守恒、电荷守恒),逐项检查配平的方程式是否正确。 [典例]根据FeS2+O2―→Fe2O3+SO2,回答下列问题: (1)氧化剂________,还原剂________,氧化产物________,还原产物________。 (2)元素化合价升高的元素为________,元素化合价降低的元素为________。 (3)1“分子”还原剂化合价升高总数为________,1“分子”氧化剂化合价降低总数为________。 (4)配平后各物质的系数依次为____________________。 答案(1)O2FeS2Fe2O3、SO2Fe2O3、SO2 (2)Fe、S O(3)114 (4)4、11、2、8 失误防范配平氧化还原反应方程式的关键是正确标出化合价,找准1“分子”氧化剂化合价降低总数,1“分子”还原剂化合价升高总数,在计算时,往往容易忽略氧化剂、还原剂中的粒子个数。 题组一正向配平类

考点一物质分离、提纯的常用方法及装置 1.物质分离、提纯的区别 (1)物质的分离 将混合物的各组分分离开来,获得几种纯净物的过程。 (2)物质的提纯 将混合物中的杂质除去而得到纯净物的过程,又叫物质的净化或除杂。 2.物质分离、提纯的常用方法及装置 (1)常规实验装置 ①过滤:适用条件:不溶性固体和液体的分离。说明:操作中a.一贴:滤纸紧贴漏斗内壁;二低:滤纸上边缘低于漏斗边缘,液面低于滤纸边缘;三靠:烧杯紧靠玻璃棒,玻璃棒轻靠三层滤纸处,漏斗下端尖口处紧靠烧杯内壁;b.若滤液浑浊,需更换滤纸,重新过滤。浑浊

的原因可能是滤纸破损、滤液超过滤纸边缘。 ②蒸发:适用条件:分离易溶性固体的溶质和溶剂。说明:蒸发结晶适用于溶解度随温度变化不大的物质;而对溶解度受温度变化影响较大的固态溶质,采用降温结晶的方法。 在蒸发结晶中应注意:a.玻璃棒的作用:搅拌,防止液体局部过热而飞溅;b.当有大量晶体析出时,停止加热,利用余热蒸干而不能直接蒸干。 ③蒸馏:适用条件:分离沸点相差较大的互溶液体混合物。说明:a.温度计的水银球放在蒸馏烧瓶的支管口处;b.蒸馏烧瓶内要加沸石;c.冷凝管水流方向应为“逆流”。

④萃取和分液:适用条件:分离互不相溶的两种液体。说明:a.溶质在萃取剂中的溶解度大; b.两种液体互不相溶; c.溶质和萃取剂不反应; d.分液时下层液体从下口流出,上层液体从上口倒出。 ⑤升华(如下左图):适用条件:除去不挥发性杂质或分离不同挥发程度的固体混合物。说明:利用物质升华的性质进行分离,属于物理变化。

⑥洗气(如上右图):适用条件:除去气体中的杂质气体。说明:长管进气短管出气。 (2)创新实验装置 ①过滤装置的创新——抽滤 由于水流的作用,使图1装置a、b中气体的压强减小,故使过滤速率加快。

Students who feel anxious are likely to experience problems like difficulty in concentrating while studying, confusion, feeling stressed while looking at difficult questions, feeling blank, sweating, sleepless, etc. Under such circumstances they end up scoring less than they could have. Therefore, it’s extrem ely important for students to learn about how to overcome fear, so that they can take their examination confidently, finally earning good grades .Here are a few tips on ways to overcome exam fear. There are many students who take studies lightly, leaving everything to be studied at the last minute. As a result, when exams are around the corner, they feel scared, as they don’t know where to start, and what to study. So the easiest way of overcoming this problem is to start studying much before the exam. Another common mistake that many students make is that they don’t make an effort to understand the subject. When they have memorized things without understanding them, the chances of forgetting are more. Therefore, it is vital to understand
