Ⅱ.阅读理解

A

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 three­year­olds 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 half­sisters.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

B

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.Non­luminous 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．non­luminous 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
