Two years ago,the Funk family of suburban Chicago adopted a Chinese baby girl who had been abandoned on a sidewalk near a textile factory in Yangzhou.

Last year,the Ramirez family of suburban Miami adopted a girl who had been abandoned a week later on the same spot.

Both families named their daughters Mia.It turns out,a first name and Chinese heritage aren’t the only things the three-year-olds have in common.The girls’ mothers—Holly Funk and Diana Ramirez—met on a website for parents who had gone through international adoptions.After a lot of emails comparing photographs and biographical details,DNA testing proved the families’ suspicions: The girls are probably fraternal twins.

“I was in shock,” said Ramirez,who lives with her husband Carlos in Pembroke Pines,Florida.“Well,now this is for real.”

The Internet and Web groups revolving around international orphanages are increasingly being used to link adopted children with biological kin(亲属).The site that Funks and Ramirezes used has a membership of 137 people,with 15 sets of twins and 7 sets of siblings whose relationships have been confirmed.

At a reunion at Chicago’s O’Hare International Airport,Mia Diamond Funk and Mia Hanying Ramirez shyly surveyed each other,and then reached for each other’s hand.

DNA tests establish an 85 percent probability that the girls are at least half-sisters.Scientists do not have a biological parent to test and reach a greater certainty,but given their ages and physical similarities,experts say it is likely they are fraternal twins.

Douglas and Holly Funk hope to bring their Mia to Miami in October. Both sets of parents say they are committed to staying in touch and often let the two sisters talk to each other on the phone.

16.Both the adopted girls shared a first name ________.

A.because they both came from China

B.because of their physical similarities

C.because their US parents suspected they were twins

D.for no good reason

17.Why did the girls’ mothers meet on the Internet?

A.To compare photographs of the two girls.

B.To find the girls’ biological kin.

C.To test their suspicions.

D.To know how to adopt children.

18.Experts are still not 100 percent sure that the two girls are fraternal twins because ________.

A.DNA tests are still not accurate enough

B.the two girls were born in two different families

C.the DNA of a biological parent is still missing

D.one girl was born a week later than the other

19.What Ramirez said in Paragraph 4 suggests that she ________.

A.didn’t believe what had happened

B.was surprised at what had happened

C.didn’t want to accept the fact

D.was pleased with what they had done

20.What would be the best title for the passage?

A.Adopted Sisters Are Reunited

B.Adopted Sisters Live Happily in the US

C.Suspicion Turned into Reality

D.The Stories of Two Families

(建议用时8′)

The earth,moon,sun and all visible stars in the sky make up less than one percent of the universe.Almost all the rest is dark matter and dark energy,unknown forces that puzzle astronomers.

Observations in recent years have changed the basic understanding of how the universe evolved and have indicated how little is known about the major forces and substances that shaped our world.

Astronomers now know that luminous(发光的) matter—stars,planets and hot gas...accounts for only about 0.4 percent of the universe.Non-luminous components,such as black holes and intergalactic(星系间的) gas,make up 3.6 percent.The rest is dark matter,about 23 percent,and dark energy,about 73 percent.

Dark matter,sometimes called “cold dark matter”,has been known for some time.Only recently have researchers come to understand the key role it played in the formation of stars,planets and even people.

“We owe our very existence to dark matter,” said physicist Paul Steinhardt.“Dark matter dominated the structure formation in the early universe,”Steinhardt said.“For the first few billion years dark matter contained most of the mass of the universe.You can think of ordinary matter as a froth(泡沫状物) of an ocean of dark matter.The dark matter dumps and the ordinary matter falls into it.That led to the formation of the stars and galaxies(星系).Without dark matter,there would be virtually no structure in the universe.”

The nature of dark matter is unknown.It cannot be seen or detected directly.Astronomers know it is there because of its effects on celestial(天上的) objects that can be seen and measured.But the most dominating force of all in the universe is called dark energy, a recently proven power that astronomers say is causing the galaxies in the universe to separate at a faster and faster speed.

21.We know from the text that ________.

A.all visible stars are very important in the universe

B.the basic understanding of the universe evolution was totally wrong

C.dark matter is also known as dark energy

D.dark energy makes up about three quarters of the universe

22.The text tells us “dark matter” ________.

A.plays an important part in forming stars,planets and humans

B.has been fully understood by researchers

C.remains an unimportant force to the universe like dark energy

D.has nothing to do with the formation of the universe today

23.“The major forces and substances that shaped our world” (in Para.2) refers to ________.

A.luminous matter B.non-luminous matter

C.dark matter D.ordinary matter

24.According to Paul Steinhardt,our existence today ________.

A.depends mainly on dark matter

B.has something to do with ordinary matter

C.results from the formation of celestial objects

D.evolves from the mass of the universe

25.Which of the following is the best title for the passage?

A.Dark Matter or Dark Energy

B.The Formation of the Universe

C.Dark Forces Dominate the Universe

D.Unknown Forces Puzzle Astronomers

答案

Ⅰ.单项填空

1.B[考查独立主格结构在句中作伴随状语。teeth与set两个词之间含有逻辑上的被动关系,所以用过去分词;look这一动作是eyes所发出,所以用looking。] 2.B[struggle against同……作斗争,符合句意。]

3.B[第一空表示“泛指”某一职业,不需要用冠词。而第二空短语have a very easy life 意思为“过着简朴的生活”,需要用冠词。]

4.C[根据语境可知:去开吧,去做吧。所以答案为C。]

5.D[expand on sth.详细说明某事。]

6.A[考查非谓语动词的用法。根据句意可知苏珊尝试着过一个人的生活,但是不喜欢。]

7.D[regret doing sth.后悔做了某事。]

8.A[A项,“无可奉告”。]

9.A[be equipped with...装备有……,且and前后形式应一致。]

10.B

11.C[turn up出现;证明出;调大;fix up修补;解决;set up建立;成立;make up 编造;化妆。]

12.D[lead to致使,导致;better此处用来表示比较。]

13.D

14.C[do you think作插入语应置于特殊疑问词后,且特殊疑问词作主语。]

15.C

得分策略

得分点16:“独立主格”结构的正确判断与运用

[经典例题]Seeing her father,the little girl ran to him,her schoolbag________ behind her.

A.flying B.flew

C.to fly D.was flying

错因分析有些考生会把后面部分当作一个句子,而句子缺少谓语动词,于是误选B 或D。其实,前后两部分之间是逗号,说明后面部分不是一个句子,而选项C表示一个还未发生的动作,显然与语境不符,因此选A项。

[得分笔记]在英语中,一般来说,非谓语动词作状语时,其逻辑主语就是句子主语。如果它的逻辑主语不是句子的主语,就必须在其非谓语动词之前加上适当的名词或代词。这样“名词或代词+非谓语动词”就构成了独立主格结构,在句子中作状语。

Ⅱ.阅读理解

16.D[推理判断题。两位母亲都给女儿取了Mia这个名字,后来在网上交流时才发现两个女孩长得很像,因此断定两个母亲取名时是无意的,仅是一种巧合。] 17.B[细节理解题。从文章第五段中的“The Internet and Web groups...”可知答案。] 18.C[细节理解题。文章倒数第二段说科学家还没有女孩亲生父亲或母亲的DNA,因此不能作出确切的判断。]

19.B[细节理解题。从第四段Ramirez所说的话可以看出她非常吃惊,但还是相信眼前发生的一切。]

20.A[标题归纳题。这两个姐妹分别被两个家庭收养,最终得以团聚。A项最能体现本文的中心。]

21.D[细节理解题。根据第三段最后一句中的“...dark energy,about 73 percent.”可知,正确答案为D项。原文中的account for与make up同义,表示“占(比例)”。] 22.A[细节理解题。通读全文可知,近年来的观察改变了天文学家对于宇宙演变历史的认识,也就是直到最近天文学家才认识到:dark matter(暗物质)又称为“cold dark matter”,在宇宙早期结构形成的过程中起主导作用。其他选项的陈述都与原文不一致。] 23.C[推理判断题。根据第五段第二句话可知,暗物质(dark matter)在宇宙早期结构形成的过程中起着支配的作用。]

24.A[细节推断题。第五段第一句话告诉我们,我们今天的存在应归功于暗物质,即暗物质决定了我们的存在。]

25.C[标题归纳题。全文的内容可以概括为:科学家最近认识到暗物质被证明是存在的一种能量,这种能量正影响着整个宇宙的构成,并主宰着宇宙。]

得分策略

面对较难的阅读材料,该如何下手?(二)

[经典例题]

The latest research suggests that the key factor separating geniuses from the merely accomplished is not I.Q.,a generally bad predictor of success.Instead,it’s purposeful practice.Top performers spend more hours practising their craft.If you wanted to picture how a typical genius might develop,you’d take a girl who possessed a slightly above average language ability.It wouldn’t have to be a big talent,just enough so that she might gain some sense of distinction.Then you would want her to meet,say,a novelist,who coincidentally shared some similar qualities.Maybe the writer was from the same town,had the same family background,or shared the same birthday.

This contact would give the girl a vision of her future self.It would give her some idea of a fascinating circle she might someday join...

Then she would practise writing.Her practice would be slow,painstaking and error-focused...

The primary quality our young writer possesses is not some mysterious genius.It’s the ability to develop a purposeful,laborious and boring practice routine.The latest research takes some of the magic out of great achievement.But it underlines a fact that is often neglected.Public discussion is affected by genetics and what we’re“hard-wired” to do.And it’s true that genes play a role in our capabilities.But the brain is also very plastic.We construct ourselves through behaviour.

76.The passage mainly deals with ________.

A.the function of I.Q.in cultivating a writer

B.the relationship between genius and success

C.the decisive factor in making a genius

D.the way of gaining some sense of distinction

答案解析C该文章相对来说比较难,但是考生如果抓住首段和尾段,就能很快找到答案。因为有关主题思想试题的答案往往会在文章首段或尾段总结时给出,抓住首尾段的内容可以轻松克服阅读材料太难的问题。本文为议论文,结构清晰。首段给出讨论的观点,第二段和第三段列举了一个小女孩如何成为一位有天赋的作家的例子,在末段再次重述成功不仅仅取决于基因遗传,更多在于自身实践改变自我的道理。对于主旨大意题,考生应在了解文章结构后,重点寻找与主旨相关的句子,进行深层阅读,把握住关键词。本文的主题可在文章第一段中的第二、第三、第四句中找到。

2019高考英语一轮复习知识点总结

2019高考英语一轮复习知识点总结 一、在复习词汇时,学生要学会自我总结 通过自我总结,学生主动取得了知识的精华,并转化为适合自己 需要的东西。善于归纳中学教材中常用词汇的基本用法及相关知识点 的异同,如:mean一词,能够表示“意思是”、“意味着”,常用于mean something/doing something,而在“mean to do something” 结构中,则是“计划”、“打算”之意。善于对有共同用法或特点的 词汇实行归纳,形成相关的小知识链。如:suggest(建议), insist(坚持要求),demand(要求)、ask(请求)等后接的宾语从句中都 要用虚拟语气。善于归纳近义词、同义词,如:在复习join的用法时,能够联系join in,take part in,join sb in归纳复习之后,要做 对应练习。这样才能扩大词汇量,又能够提升实际使用英语水平。 二、句型复习应结合课本的例句实行 中学英语课本的句型很多,有强调句、祈使句、倒装句、省略句、反意疑问句、插入语等句型。这些都是高考的常考点。我们通过复习 课本的例句,总结归纳这些句型的特点、用法及它们的适用条件,既 掌握英语的基本句型用法,又能够促动我们的英语谴词造句水平。 三、语法复习要考虑语境 通过语境来训练我们的语言使用水平。每一个语法项目的复习可 分三个层次实行:复习要点、主要考点、精选练习。如果能做到这个点,定能做到学以致用。现在高考英语试题淡化了语法,但学好语法 却是准确和规范使用英语的保证。所以,语法复习不可轻视。 四、重视交际用语复习 如今高考试题越来越重视考查学生的英语交际水平,而且中学英 语教材的每一单元都有以交际功能贯穿的对话课。所以,学生在复习时,要注意对各单元的对话实行排列分类,整理归纳,总结出相关话

人大附中高中英语新高考语法一轮复习讲义(11)than,as和but作关系代词用法知识点总结整理

2021届人大附中高中英语新高考语法一轮复习讲义(11)than,as和but作关系代词用法知识点总结整理 than, as, but作准关系代词的用法 关系代词通常是用来引导定语从句的,than, as和but除了做 基本连词外还可以作准关系代词,但是与which,who,that等关系 代词不同,than, as和but引导的定语从句与典型的定语从句不太 相像,因此称它们为准关系代词。 Than,as,but作准关系代词条件是:前面必须有先行词(名词) 例: I have more money than you do (我比你有钱) He has as much money as I do (他和我的钱一样多) There is nothing but he knows(没有什么他不知道的) 我们分别进行详细说明: 1.Than 作准关系代词的用法 Than 之前若有名词,则than = than + the + 前面的名词+ 关系代词(who, whom, which),因此可以将than 视为关系代词。Than 作准关系代词通常出现在more …than,less…than, fewer…than等结构中,且在从句中可以充当主语,宾语和be动 词后得表语。 例1. I have more money than is needed.(than作从句的 主语)

= I have more money than the money which is needed (我现有的钱比所需要的多) 例2. I have more money than h e needs(than作从句的宾语) I have more money than the money which he needs (我现有的钱比他所需要的多) 例3. heis a better student than you(are ).(than 作从句的表语) 2.As 作准关系代词的用法 as之前若有名词,则as = as + the + 前面的名词+ 关系代词(who, whom, which),因此可以将as 可视为关系代词,并在所引导的从句中作主语,宾语和be动词之后的表语。但只用于下列短语中: as作为准关系代词只能用于下列短语: 1. Such+n. + as... 例: I don't like such a man as tells lies(as作从句的主语) 我不喜欢说谎的人 2. The same+ n. + as... 例: I have the same book as you bought yesterday(as作从句的宾语) 我有一-本书和你昨天买的-样

2021届新高考英语一轮复习阅读理解专项训练(3)健康环保类

2021届新高考英语一轮复习阅读理解专项训练(3) 健康环保类 1.From talking robots and video phones to rovers on Mars, technology has become so advanced that the previously impossible seems to occur on a daily basis. And yet – we still have no cure for the common cold. Why can’t we st op the common cold? According to Peter Barlow, a scientist at Edinburgh Napier University in the UK, the main challenge lies in the many different types of cold viruses that are produced by the rhinoviruses (鼻病毒). There are at least 160 types. They mutate (突变) so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isn’t likely to work on every type of cold. However, researchers from Stanford University and the University of California, San Francisco, have found a possible answer. They discovered a protein that the viruses need. Without it, they can’t spread inside your body. To identify the gene which produces the specific protein needed by the viruses, researchers used a gene-editing technique to test all genes in the human genome (基因组) one by one for thousands of cells. These modified (改变的) cells were then exposed to a range of enteroviruses(肠病毒), including the rhinoviruses which cause the common cold. All the viruses were unable to replicate (复制) inside cells without a gene that produces a specific protein, called methyltransferase SETD3. Then, they tested genetically modified mice, which were completely unable to produce the protein. The mice were able to live healthy, normal lives wit hout the protein. “Lacking that gene protected the mice completely from viral infection.” associate professor Jan Carette, from Stanford, told the BBC. “These mice would always die, but they survived and we saw a very strong reduction in viral replication and very strong protection.” Carette said the plan is to find a drug which can temporarily suppress (抑制) the protein, instead of producing genetically modified humans. “We have identified a fantastic target that all enteroviruses and rhinoviruses require and depend on.
