    China has announced it's abolishing its one-child policy. What difference has it made, statistically speaking?

    400 million births prevented. The one-child policy, officially in place since 1979, has prevented 400 million births. Parents have faced fines and other punishments for having more children.

    The majority of the decrease in China's fertility(生育)rate happened in the 1970s.It dropped from 5.8 children per woman in 1970 to 2.7 in 1978. Despite the one-child policy the rate had only fallen to 1.7 by 2013. 21:28 baby death rate. Since the one-child policy was introduced, baby girls have become more likely to die than boys.

    In the 1970s, according to the United Nations, 60 males per 1,000 live births died under the age of one. For girls the figure was 53. In the 1980s, after the one-child policy became official, the rate for both was 36. By the 1990s, 26 males per 1,000 live births died before the age of one-and 33 girls. The 2000s saw 21 boys per 1,000 live births dying and 28 girls.

    1.16 boys born for every girl

    Sexually selective abortions have been considered as a major cause of China's unusual sexual imbalance.

    Gietel-Basten, associate professor in social policy at Oxford University, says the births of many girls are not registered if parents have broken the rule by having two children, adding officials often turn a blind eye. It's estimated there are now 33 million more men than women in China.

    4:2:1 families

    With the ageing of China's population and the continuation of the one-child policy, a “4: 2 :1”home is the description given to households in which there are four grandparents cared for by two working age parents, who themselves have one child.

    By 2050, it's predicted that a quarter of China's population will be 65 or older. The predicted decline in the number of people of working age is thought to have persuaded the government to drop the one-child policy.

(1)、When was the baby death rate for both boys and girls equal?
A、In the 1970s. B、In the 1980s. C、In the 1990s. D、In the 2000s.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余项。

    Before going outside in the morning, many of us check a window thermometer (温度计) for the temperature. This helps us decide what to wear.

    {#blank#}1{#/blank#}. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don't feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.

    Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale. Both systems use the freezing and boiling points of water as their guide. {#blank#}2{#/blank#}.

    The most common kind of thermometer is made with mercury inside a clear glass tube. As mercury (or any other liquid) becomes hot, it expands. As it gets colder, it contracts. That is why on hot days the mercury line is high in the glass tube. {#blank#}3{#/blank#}.

    First, take a clear glass juice bottle that has a cap; fill the bottle with colored water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw through the nail hole.

{#blank#}4{#/blank#}.

    Finally, place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.

    {#blank#}5{#/blank#}. As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

A. Now that you know this rule you can make a thermometer of your own that will work.

B. People use thermometers which are made by themselves when travelling around the world.

C. We use and depend on thermometers to measure the temperature of many other things in our daily lives.

D. The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.

E. Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.

F. Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal them together.

G. They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degree and boils at 100 degrees.

    Last year I ruined (毁) my summer vacation by bringing along a modem convenience that was too convenient for my own good: the iPad. Instead of looking at nature, I checked my email. Instead of paddling a small boat, I followed my Twitter feed (推特简讯). Instead of reading great novels, I stuck to reading four newspapers each morning. I was behaving as if I were still in the office. My body was on vacation but my head wasn't.

    So this year I made up my mind to try something different: withdrawal (退出) from the Internet. I knew it wouldn't be easy, since Fm bad at self-control. But I was determined. I started by giving the iPad to my wife.

    The cellphone signal (信号) at our house was worse than in the past, making my attempts at cheating an experience in frustration (沮丧). I was trapped, forced to go through with my plan. Largely cut off from email, Twitter and my favorite newspaper websites, I had few ways to connect to the world except for radio and how much radio can one listen to, really? I had to do what I had planned to all along: read books.

    This experience has had a happy ending. With determination and the strong support of my wife, I won in my vacation struggle against the Internet, realizing finally that it was I, not the iPad, that was the problem. I knew I had won when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi. “I don't need it,” I said.

    However, as we return to post-vacation life, a harder test begins: Can I continue when Fm back at work? There are times when the need to know what's being said right now is great. And I have no intention (愿望) of giving up my convenience completely. But I hope to resist (抵抗) the temptation (诱惑) to check my email every five minutes, which leads to checking my Twitter feed and a website or two.

    I think a vacation is supposed to help you reset your brain to become more productive. Here I hope this one worked.

    An 18-year-old US girl gained unexpected appreciation and a surprise after she gave “extra help” to an elderly man in the restaurant she was working.

    It's social media that made her seemingly small action go viral and brought her appreciation from hundreds of thousands of strangers and a scholarship to Texas Southern University.

    The heroine Evoni Williams has reportedly been working full-time to earn money for further study in a restaurant in La Marque, Texas,the United States. It was last week when an old man named Adrian Charpentier asked for help to chop his ham for his hands were weak because of illness. On that busy morning when she had loads of work on shoulder, Williams helped the man without hesitation. The moment she was leaning over the counter and cutting the ham was shot by a customer known as Laura Wolf.

    Wolf posted the picture on the Internet and wrote, “I'm thankful to have seen this act of kindness and caring at the start of my day while everything in this world seems so negative. If we could all be like this waitress and take time to offer a helping hand…” According to local reports, Wolf didn't know Williams, neither did Williams know her act was shot and shared on the web. However, the small act of kindness soon accumulated its own power on and outside the Internet.

    Besides praise from netizens and media reports across the United States, a 16000-dollar scholarship to Texas Southern University was recently granted to Williams to support her study plan on business management.

    “We wanted to reward Evoni's act of kindness and let her know that good deeds do not go unnoticed,” said Melinda Spaulding, an administrator at Texas Southern University.

    People have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, jiving for around 50 to 70 years.

    Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

    According to the research, the extra copies of the gene improved the animal's sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

    "An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals," the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.

    This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox (悖论)”". Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.

    The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.

    "Nature has already figured out how to prevent cancer," said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. "It's up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people."
