We believe every kid deserves a childhood. The opportunity to be a kid. Sunshine in dark days. That's why we've partnered with The Sunshine Kids?.
The non－profit Sunshine Kids?， established in 1982, is committed to bringing sunshine to young cancer patients' lives by providing positive group activities and emotional support, helping them do what kids are supposed to do—have fun and celebrate life. The foundation provides a variety of free programs and events for kids receiving cancer treatments in hospitals across North America.
Each year Berkshire Hathaway HomeServices network members raise $2 million＋ through a wide variety of fundraisers and community events, and through ticket sales and contributions made at our annual Sales Convention.
The Sunshine Kids? and Berkshire Hathaway HomeServices look forward to the day when the Foundation will no longer need to exist. But until that day, both organizations remain dedicated to the cause.
Talk to your Berkshire Hathaway HomeServices agent to see how you can bring sunshine into the lives of young cancer patients.

Researchers around the world interested in uncovering complex human disorders, such as Alzheimer's disease, could soon have access to cloned monkeys with genomes that have been edited to display these conditions in China.
On 24 January, scientists at the Institute of Neuroscience (ION) in Shanghai reported that they had used gene－editing to disable a gene in monkeys that is crucial to their sleep－wake cycle. The scientists then cloned one of those monkeys to produce five primates(灵长目动物) with almost identical(相同的) genes. It is the first time that researchers have cloned a gene－edited monkey.
Primates are the best animal model for studying higher cognitive(认知的) functions and brain disorders in humans, says neuroscientist Mu－ming Poo, ION's director and co－founder of the new 720 million yuan (US$106 million) centre. The advantage of creating cloned monkeys is that it reduces the number of animals needed for certain types of experiments, such as testing whether a drug works.
But some scientists think that experiments using monkeys should be a last approach because of their higher levels of cognition. Mitchell Lazar, who studies metabolic disease at the University of Pennsylvania, says that some experiments in mice—for example, research into the genes behind human diseases—are equally appropriate scientifically as in primates. Research in mice is also more accepted by the public, and the animals are cheaper and quicker to produce. Lazar worries that if scientists have ready access to populations of gene－edited monkeys, they might use them for experiments when rodents(啮齿动物) would do.
Poo says that mice are not a good substitute for studying higher cognitive functions and brain disorders in humans. He argues that cloning will reduce the burden on monkeys by cutting the number used in labs. The ION follows strict international guidelines for animal research, he says.
Poo's team will continue to study the effect of gene editing on their five cloned monkeys. The group disabled a gene, BMAL1, that has a crucial role in maintaining circadian rhythm(生理节奏), the internal clock that helps a healthy sleep－wake cycle. In people, BMAL1 mutations have been linked to diabetes, hypertension and depression.
The monkeys with the disabled BMAL1 genes move more at night and sleep less overall. They also display psychosis－related symptoms, such as fear and anxiety, when put in unfamiliar environments.
The team's next step is to look in detail at the neural(神经的) mechanisms that might create these problems. It will also take advantage of the genetically identical monkeys to hunt for diagnostic markers of circadian rhythm－related disorders and possible treatments.
( )58. Why were the genetically identical monkeys cloned?
A. To prove scientists' innovation in cloning animals.
B. To study the rare characteristics of cloned monkeys.
C. To explore many possibilities for monkeys' cognition.
D. To provide improved animal models of human diseases.
( )59. What does Mitchell Lazar think of cloning monkeys?
A. It is of little value.
B. It is of much practice.
C. It is hardly acceptable.
D. It is completely illegal.
( )60. From the passage we can know that Poo's team will ________．
A. continue to disable a gene on the monkeys
B. try to clone more monkeys and edit their genes
C. find the similarities between humans and monkeys
D. determine the cause of sleep disorders and find cures
( )61. What's the main idea of the passage?
A. Chinese effort to clone gene－edited monkeys kicks off.
B. Chinese dream to clone monkeys has finally come true.
C. Cloning monkeys is an important breakthrough in science.
D. Cloning gene－edited monkeys has caused some moral risks.
We are obsessed(迷恋) with ourselves. We study our history, our psychology, our philosophy. Much of our knowledge revolves(使旋转) around humankind itself, as if we were the most important thing in the universe.
But in the course of the centuries we have come to realize just how many wrong ideas we've had. We have learned of the existence of black holes, waves of space, and of the extraordinary molecular structures in every cell of our bodies.
The more we discover, the more we understand that what we don't yet know is greater than what we know. The more powerful our telescopes, the stranger and more unexpected are the heavens we see. The closer we look at the minute detail of matter, the more we discover of its profound structure.
In a famous story told by Plato in the seventh book of The Republic, some men are chained at the bottom of a dark cave and see only shadows cast upon a wall by a fire behind them. They think that this is reality. One of them frees himself, leaves the cave and discovers the light of the sun and the wider world. At first the light, to which his eyes are unaccustomed, stuns and confuses him. But eventually he can see and returns excitedly to his companions to tell them what he has seen. They find it hard to believe.
We are all in the depths of a cave, chained by our ignorance, our prejudices, and our weak senses reveal only shadows. If we try to see further, we are confused: we are unaccustomed. But we try. This is science. Scientific thinking explores and redraws the world, gradually offering us better and better images of it, teaching us to think in ever more effective ways. Its strength is its capacity to demolish(推翻) old ideas, to reveal new regions of reality, and to construct new, more effective images of the world. This adventure rests upon the entirety of past knowledge, but at its heart is change.
The incompleteness and the uncertainty of our knowledge, hung over the abyss(深渊) of what we don't know, does not make life meaningless: it makes it interesting and precious.

A. The new discoveries of the universe prove to be wrong.
B. Man has created splendid cultures in the course of centuries.

( )63. The story told by Plato is meant to ________．
A. make us aware of the cruelty of reality
B. encourage us to explore the unknown world
C. applaud the heroic deeds of chasing freedom
D. justify our ignorance and prejudice about the world
( )64. What does the author want to stress in the passage?
A. Exploring the universe makes our life meaningful.
B. Leaving things as they are makes our life perfect.
C. New discoveries of the universe will cause confusion.
D. Past knowledge prevents us constructing a new world.
It was 2012, and somewhere on a cassava (木薯) and banana farm in rural Tanzania, there were four of us standing in a circle: me, two farmers named Joyce and Elijah, and the former secretary general of the United Nations, Kofi Annan.
Elijah and Joyce did most of the talking. They told us how this farm was unlike any they had worked on; how there were improved crop varieties and new tools to process the harvest. There was even a daycare centre near the farm. This way, women could spend more time selling what they grew. I rattled off(不假思索地说出) some questions. Do you sell your cassava only here—or do you ship it somewhere else? How far is the market? Have you seen a difference in your yields? Kofi, though, mostly listened.
Later, after we left the fields and walked towards the daycare centre where there was a bigger crowd, Kofi started talking. He was telling jokes, trying to put everyone at ease, and doing a very good job of it. The man had the deepest, most infectious laugh I've ever heard and an incredibly commanding voice. He sounded like an actor playing himself.
Kofi and I had attended a lot of the same UN events, and he'd visited our foundation's offices in
