    You carry a 1.3 kg mass of fatty material in your head that controls everything you will ever do. This fantastic control center lets you think, learn, create, and feel emotions. It also controls everything your body does. What is this amazing machine? It's your brain — a structure so amazing that the famous scientist James Watson called it "the most complex thing we have yet discovered in our universe".

    Imagine your kitten jumped onto the kitchen counter, and was about to step onto a hot stove. You would have only seconds to act. In situations like this, your brain reads the signals from your eyes and quickly calculates when, where and at what speed you need to run to save her. Then it tells your muscles to move. No computer can match your brain's great ability to download, process, and react to the flood of information from your eyes, ears and other sensory organs.

    If a bee lands on your foot, sensory neurons(神经元) in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses motor neurons to send a message back to your foot: Shake the bee off quickly! Motor neurons can send this information at more than 320 kilometers per hour!

    Your brain contains about 100 billion tiny cells: neurons — it would take you more than 3,000 years if you tried to count them all. Whenever you dream, laugh, think, see or move, tiny chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways. Believe it or not, the activity in your brain never stops. Countless messages fly around inside it every second, like a super-fast game of table tennis. Your neurons create and send more messages than all the phones in the entire world. And although a single neuron generates only a tiny amount of electricity, all your neurons together can generate enough electricity to power a light bulb.

(1)、By "the most complex thing", James Watson means __________.
A、a supercomputer B、the universe C、human brains D、our emotions
(2)、Which of the following statements is true according to the 2nd and 3rd paragraph?
A、Brains can download more information than any computer. B、The kitten plays an important role in testing human brain power. C、Motor neurons in human brains serve to send countless messages. D、Your brains can use neurons to send messages back faster than bees'.
(3)、The author mentions "to power light bulbs" (Para. 4) to show __________.
A、neurons can send lots of messages B、how many active tiny cells brains contain C、how much electricity brains can generate D、there is countless information in the brain
(4)、What is the main idea of the passage?
A、Powerful brain is a wonderful machine. B、Brains work well in controlling body movements. C、Brain is the most complex structure in the universe. D、Human brains are composed of numerous neurons.

    My 17-year-old daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production, one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night light, she takes one last look at the bedroom and says, “Dear night lights, protect my sleeping children.” As a mother, I know how much she loves her children.

    It has been several weeks since we took our daughter to college and she seems to be adjusting  well after a short period of homesickness. For us, though, it's another story. Like most parents, I love checking in on my children at night. But now she's gone, and I find night times the hardest. I miss her most at night.

    In my neighborhood, most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. One friend talked about getting this sick feeling in her stomach as she prepared for the college drop-off. We complained that many of us were too busy to truly enjoy being with our children while we had them.

    For us moms, seeing Toy Story 3 only made the sadness worse as we watched the character Andy, who is the same age as our kids, say goodbye to his childhood as he prepares to leave for college. And it's not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn't get any easier. “You feel like something has been taken away from inside you” said one of them.

    I imagine things will get easier with time, especially as I see my daughter adjust to college life. Meanwhile, as I keep my cell phone close to me in bed and text my daughter goodnight and sweet dreams every night, I like to think that messages serve as a night light that keeps her safe.

    In a historic moment on June 26, the US Supreme Court ruled that same-sex marriage is a legal right across all 50 states. The Supreme Court justices ruled states cannot deny gay men and women the same marriage rights. The decision means the 13 states with bans on same-sex marriage are no longer able to enforce them.

    Same-sex couples “ask for equal dignity in the eyes of the law”. Justice Anthony Kennedy wrote in the majority opinion: “The Constitution grants them that right.”

    The decision came after decades of litigation(诉讼) and activism. It set off celebrations across the US. In affected states including Georgia, Michigan, Ohio and Texas, same-sex couples rushed to wed, while officials in Mississippi and Louisiana said marriages had to wait until procedural issues were addressed, reported the BBC.

    According to “The New York Times”, the ruling came against the backdrop of fast-moving changes in public opinion in the US, with polls indicating that most Americans now approve of same-sex marriage.

    US President Barack Obama welcomed the ruling, saying it “affirms what millions of Americans already believe in their hearts.” “Today,” he said in a press release, “we can say, in no uncertain terms, that we have made our union a little more perfect.”

Another win.

    This was the second time the Supreme Court took up same-sex marriage, according to an article in “Business Insider”. The first time, in June 2013, the court made a decision that allowed the US federal government to recognize same-sex marriages in states where they were already legal.

    But at that time, the Supreme Court declined to rule on the broader question about gay marriage: Is there a constitutional(宪法的) right to same-sex marriage? The June 26 ruling gave a positive answer to that question.

Justice Kennedy wrote in the majority opinion that the Constitution should evolve with societal changes.

    “The nature of injustice is that we may not always see it in our own times,” he wrote. “The generations that wrote and ratified the “Bill of Rights” and the “Fourteenth Amendment(修正案)” did not exactly know the extent of freedom in all of its dimensions, and so they hoped the future generations can protect the right of all persons to enjoy liberty as we learn its meaning.”

    The Fourteenth Amendment addresses citizenship rights and equal protection of the law. In the June 26 ruling, the Supreme Court declared that the equal protection clause of the amendment requires marriage rights be extended to same-sex couples, too.

    Good Morning Britain's Susanna Reid is used to grilling guests on the sofa every morning, but she is cooking up a storm in her latest role-showing families how to prepare delicious and nutritious meals on a tight budget.

    In Save Money: Good Food, she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste, while preparing recipes for under £5 per family a day. And the Good Morning Britain presenter says she's been able to put a lot of what she's learnt into practice in her own home, preparing meals for sons, Sam, 14, Finn, 13, and Jack, 11.

    "We love Mexican churros, so I buy them on my phone from my local Mexican takeaway restaurant," she explains. "I pay £5 for a portion(一份),but Matt makes them for 26p a portion, because they are flour, water, sugar and oil. Everybody can buy takeaway food, but sometimes we're not aware how cheaply we can make this food ourselves."

    The eight-part series(系列节目),Save Money: Good Food, follows in the footsteps of ITV's Save Money: Good Health, which gave viewers advice on how to get value from the vast range of health products on the market.

    With food our biggest weekly household expense, Susanna and Matt spend time with a different family each week. In tonight's Easter special they come to the aid of a family in need of some delicious inspiration on a budget. The team transforms the family's long weekend of celebration with less expensive but still tasty recipes.

    The faces of the four U. S. presidents on Mount Rushmore will likely last for centuries. But at a newly opened exhibit in Japan, you can catch them only for about eight months. This year, the annual sand sculpture event at the Sand Museum in Tottori, Japan, is focused on another country. This is the 10th anniversary of the event. Artists came from 19 countries to shape sand into different sculptures that represent events in U. S. history and American landmarks.

    Tottori is a remote city in western Japan. In the past, not many tourists traveled to it. To attract more visitors, Tottori officials decided to use a natural resource: sand. They decided to create a sand museum that would house a series of sand sculptures based on different geographic areas of the world. The sand from each year's exhibition is used again the next year. The project has been a success. About 500,000 people visit the museum during the eight months. Some return year after year to see the new sculptures.

    The city is now a popular spot for sand sculpture artists too. Sculptors from around the world come to Tottori each spring, spending a few weeks working on their masterpieces. They use special tools to smooth the sandy surfaces, cut angles and details. They use only sand and water to create the huge sculptures, some of which tower over their creators.

    Originally, the artists built their creations outside. But the works lasted less than two months outdoors. So the museum built a permanent structure 10 house the artworks, which extended their life to eight months. Now many more tourists get to see the sculptures. Still, the fact that this art is not permanent is part of the appeal. The temporary sculptures reflect the Japanese value of appreciating the fleeting(稍纵即逝)nature of the world.

    Tottori is not the only Japanese town that shows temporary art like this. Sapporo, in northern Japan, hosts a similar exhibit in the winter, using snow instead of sand. Thai will be just about the time that the U. S. sand sculpture exhibition is taken apart, and the sand is saved for next year's show.

Hair Loss (Alopecia)

    Information about male pattern baldness(秃顶) causes, triggers and treatment in the UK.

    In contrary to popular belief, hair loss­or alopecia­can start at any age. While it is associated with mature males, and statistics show it does mainly affect men above 40, the reality is you can notice symptoms in your 30s, or even 20s and teen years.  The NHS statistics state that 25% of men start losing their hair by the time they reach 30. The most common form of hair loss is male pattern baldness­also known as androgenic alopecia­that affects more than half of men around the world.

    One option many men seek is treatment to avoid further hair loss, especially early on in the process. With treatments, such as Propecia, that specifically target male pattern baldness, it is possible to stop hair loss completely and even encourage fresh new hair growth.

    What is alopecia?

    Alopecia is the medical term for hair loss. Most commonly affecting males, hair loss in men is caused by an increased sensitivity to the male sex hormones (androgens). The type of alopecia you have (as well as hereditary and external factors) can influence levels of hair loss. The most common type of hair loss (alopecia) is male and female pattern baldness. Other types include:

    * Alopecia areata (patches of baldness, usually on the scalp)

    * Scarring alopecia (hair loss directly affecting the hair follicles)

    * Telogen effluvium (hair thinning over a larger area on the top of the head, rather than bald patches)

    * Anagen effluvium(most commonly caused by cancer treatments such as chemotherapy and radiotherapy)

    The Secretary-General of the U.N. has always been chosen in private meetings. But for the first time in its 70-year history, part of the selection process is taking place in public.

    At least eight countries have announced their candidates (候选人) for the position, among whom are women, including Irina Bukova from Bulgaria, Susana Malcorra from Argentina and Helen Clark from New Zealand. 56 countries says the next U.N. chief should be a woman. There have been eight U.N. chiefs, none of whom was a woman.

    All member states were permitted to ask the candidates questions during two hour-long meetings last week in the U.N. General Assembly (联合国大会). The candidates were also asked some of the 1,000 questions written by people on social media.

    They were asked questions about development, how they would improve efforts to create peace and how they would protect human rights.

    The U.N. Security Council will examine the candidates' backgrounds. Then the 15 members will vote secretly until one person is chosen. The General Assembly will then vote on whether to accept the choice.

    Britain, China, France, Russia and the United States are the five permanent members of the Security Council. Experts say they are likely to have more influence on who will be the new secretary-general than the 10 non-permanent nations on the council.

    The Security Council will begin to discuss who will be named the next secretary-general in July. A new secretary-general may not be confirmed until as late as November.

    The U.N. has a tradition of choosing its new leader from a part of the world different from its current leader. U.N. Secretary-General Ban Ki-moon is from Asia. The previous U.N. chief was Kofi Annan, who was from Africa.

    Dan Thomas is a spokesman for the president of the General Assembly. He says there is no rule that says where a new secretary-general must come from. But most observers say the new U.N. chief will not be from Asia or Africa.
