Scientists are fond of running the evolutionary clock backward, using DNA analysis and the fossil record to figure out when our ancestors stood straight and split off from the rest of the primate evolutionary tree. But the clock is running forward as well. So where are humans headed? Here's a thoughtless assessment of possible paths, ranging from similar humans to alien-looking hybrids bred for interstellar (星际的) travel.
Different populations of a species have to be separated from each other in order for those populations to diverge into separate species. Populations are increasingly in contact with each other, leading to greater gene-mixing. It's believable that separate species would appear. Evolution is still at work and the trend may well be accelerating. Cultural diversity is fading as human society becomes more interconnected globally.
The radical king of evolution moves much more quickly than biological evolution. High-tech improvements are ranging from Supermen, to camera-equipped flying drones(遥控飞机), to pills that keep soldiers going without sleep or food for days. To date, genetic medicine has focused on therapies that work on only one person at a time. The effects of those therapies aren't carried on to future generations. Tinkering with the germline could conceivably produce a superhuman species in a single generation-but could also conceivably create a race of monsters.
Today the rapid pace of cybernetic(计算机控制论的) change has led to worry that artificial intelligence may outpace human’s natural smarts. In some fields, artificial intelligence has already bested human. We're already making machines that can be assimilated (同化) including artificial limbs, mechanical hearts, and artificial retinas (视网膜).
If humans survive long enough, there's one sure way to grow new branches on our evolutionary family tree by spreading out to other planets. If humans established a permanent settlement on other planets, the radically different living conditions would change the evolutionary equation (方程式) What will be inconceivable millions of years from now? Two intelligent species, human and machine, definitely work together to spread life through the universe.
Scientists study the evolution according to      .

A.different populations of a species
B.DNA analysis and the fossil record
C.cultural diversity and greater gene-mixing
D.high-tech enhancements and biological evolution

Which is NOT true about human beings' evolution?

A.New species will appear.
B.Human's evolution is faster than biological evolution
C.Cultures will become more colorful.
D.The evolution might create a race of monsters.

What might bring threat to human beings?

A.Supermen. B.Monsters.
C.Alien. D.Artificial intelligence.

Which of the following must happen in the future?

A.Humans survive long enough.
B.Humans spread out to other planets.
C.Human and machine work together.
D.Living conditions change the evolutionary equation.

I had this exchange with my 6-year-old last week.
Him: Mom, we have to start buying Danimals.
Me: Why?
Him: So, I can bring it to |school for lunch.It's yogurt .
Me: Why do you want it so badly?
Him: Because Danimals i|s giving away five fantastic Caribbean vacations.
I had to explain that there was little chance that he would win a vacation.It's a strategy used to encourage kids to beg for artificially-colored (人工着色的) yogurt that costs a lot.
Marketing follows my kids —and yours—wherever they go .It comes via TV commercials. Store displays and websites are also constantly selling at our kids .But the most powerful means in kids" lives is the presence of licensed characters on every product imaginable.
Children can begin their day in character clothing.There's even character -themed wall paint available.A breakfast in a character bowl can be followed by a character toothbrush and character toothpaste(牙膏), character soap and shampoo, and a character wash cloth and towel .Then, they can put on character clothing and character shoes.Check that, character clock on the wall: Is it time for characier-shaped fruit snacks yet?
Surround kids with enough of the characters and they'll come to believe they need them.Most of us, of course, don't buy all those items.But say no to four products out of five and your home can still get filled with these tiny items encouraging brand loyalty (品牌忠诚)
At this time of year, parents buy licensed school supplies.With so much marketing around us, it can be tough to stop the tide.
"One thing that helps parents'is that they can talk to other parents about, this kind of thing," Linn suggested ."If you decide you want to buck this, it helps to find other people who will do the same thing .That way, if your child says."Everyone's doing it," you can really have a sense of whether everyone is." |

An old problem is getting new attention in the United States—bullying.Recent cases included the tragic case of a fifteen-year-old girl whose family moved from Ireland.She hanged herself in Massachusetts in January following months of bullying.Her parents criticized her school for failing to protect her.Officials have brought criminal charges against several teenagers.
Judy Kaczynski is president of an anti-bullying group called Bully Police USA.Her daughter Tina was the victim of severe bullying starting in middle school in the state of Minnesota.She said, "Our daughter was a very outgoing child.She was a bubbly personality, very involved in all kinds of things, had lots of friends.And over a period of time her grades fell completely.She started having health issues.She couldn't sleep.She wasn't eating.She had terrible stomach pains.She started clenching her jaw and grinding her teeth at night.Didn't want to go to school."
Bullying is defined as negative behavior repeated over time against the same person. It can involve physical violence.Or it can be verbal — for example, insults or threats.Spreading lies about someone or excluding a person from a group is known as social or relational bullying.
And now there is cyberbullying, which uses the Internet, e-mail or text messages.It has easy appeal for the bully because it does not involve face-to-face contact and it can be done at any time.
The first serious research studies into bullying were done in Norway in the late 1970s.The latest government study in the United States was released last year.It found that about one-third of students age twelve to eighteen were bullied at school.
Susan Sweater is a psychologist at the University of Nebraska-Lincoln and co-director of the Bullying Research Network.She says schools should treat bullying as a mental health problem to get bullies and victims the help they need.She says bullying is connected to depression, anxiety and anti-social behavior, and bullies are often victims themselves.
From the case of Tina, we can know that.

A.bullying is rare B.victims suffered a lot
C.schools are to blame D.personalities are related

Which of the following is NOT bullying?

A.To beat someone repeatedly. B.To call someone names.
C.To isolate someone from friends. D.To refuse to help someone in need.

Why is cyberbullying appealing to the bully?

C.Because it is more convenient. D.Because it can avoid cheating.

According to Susan Sweater,.

A.bullies are anti-social B.bullies should give victims help
C.students are not equally treated D.bullies themselves also need help

Which of the following can be the best title of the text?

A.Bullying—Old Irish Girl Committed Suicide

Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child’s physical, sensory, communicational and social development.Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for Kindergarten.
There are good reasons for the government to push early childhood education.Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life.Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail.
There are also negative parts to putting a child in formal education programs too early.Time Magazine online explains that “the younger the child the less his chances of catching up with first-grade work.” I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school.Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier.
Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a “false start”, as the gains are lost in middle and high school years.It seems that environment is a bigger factor on life’s success than early education.Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children.Perhaps it is time to find other ways to close that gap.
The purpose of the government valuing the early childhood education is ________.

A.to develop the children’s communication
B.to give orphaned children good care and education
C.to get the children prepared for the kindergarten
D.to train the children formally and regularly

Breathe, wave and smile. Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.
It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement (graduation ceremony).
Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.
Our principal, Mr. Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).
Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”
Then came the core (the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.
To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.
A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.
What’s the article mainly about?

A.An American high school’s graduation ceremony.
B.The opening ceremony of a sports meeting.
C.A presentation of college diplomas.
D.A US college’s farewell party.

Which of the following statements about the author is FALSE?

A.She was one of the graduates. B.She was a foreign exchange student.
C.She was excited to receive her diploma. D.She felt it great to be at the ceremony.

The right order of the following events is______.
a. Diplomas were presented to graduates.b. Students gave farewell speeches.
c. The US national anthem was played. d. The principal gave a short, warm speech.
e. Seniors went into the stadium.

A.b,c,a,d,e B.c,d,b,e,a C.d,b,e,a,c D.e,d,c,b,a

From the text, we can conclude that_______.

A.a diploma ensures a good job
