In his Annual Letter 2015, Gates made the prediction that Africa’s agriculture industry would increase productivity by 50% by 2030. Now the continent buys about $50 billion worth of food from other countries each year, although 70% of people in Africa are farmers. “In the next 15 years，however，creations in farming will solve the food problem in Africa,” Gates wrote. “The world has already developed crops that are more productive; with all the technologies, African farmers could possibly double their harvests.”

By 2035, there could be almost no poor countries. In his Annual Letter 2014, Gates bravely predicted that continued levels of foreign help could mean there would be almost no more poor countries by 2035. “Almost all countries will be what we now call lower-middle income or richer,” Gates explained. “Countries will learn from their most productive neighbors and benefit from things like better seeds and the digital revolution. ”

By 2030, the world will discover a clean-energy breakthrough to power our world. One of Gate’s more hopeful predictions which came in 2016 said that wind, solar, or some other renewable resources would power most of the world within 15 years. “The difficulty we face is big, perhaps bigger than many people imagine,” he wrote in his letter. “But so is the chance to make things better.” Many of the poor countries he visited had no running water or electricity. At night this meant they couldn’t light or power their homes, and keep businesses open.” If the world can find a type of cheap, clean energy, it will do more than prevent climate change,” he wrote. “It will change the lives of millions of the poorest families.”

At one point along an open road, I came to a crossing with a traffic light. I was alone on the road by now, but as I drove near the light, it turned red and I made a stop. I looked left, right and behind me. Nothing. Not a car, no suggestion of car lamps, but there I sat, waiting for the light to change, the only human being for at least a mile in any direction.

I started wondering why I refused to run the light. I was not afraid of being caught, because there was clearly no policeman around, and there certainly would have been no danger in going through it.

Much later that night, the question of why I’d stopped for that light came back to me. I think I stopped because it’s part of a contract we all have with each other. It’s not only the law, but it’s an agreement we have, and we trust each other to honor it: we don’t go through red lights.

Trust is our first inclination. Doubting others does not seem to be natural to us. The whole construction of our society depends on mutual trust, not distrust. We do what we say we’ll do; we show up when we say we’ll show up; and we pay when we say we’ll pay. We trust each other in these matters, and we’re angry or disappointed with the person or organization that breaks the trust we have in them.

I am so proud of myself for stopping for the red light that night.

My fiance(未婚夫）and I were excited about shopping for our first home.But our funds were limited,and none of the houses in our price range seemed satisfactory.

One agent recommended a house in particular..Although her description sounded wonderful,the price was beyond our range,so we declined.But she kept urging us to have a look at least.

We finally did and it was love at first sight:It was Our Home,small and charming, overlooking a quiet lake.Walking through the rooms and talking with the owners,a nice elderly couple,we felt the warmth and happiness of the marriage within that home.As perfect as it was,the price remained too high for us.But every day,we would sit by the lake, looking at the house and dreaming of what it would be like to live there.

Days later,we made a(n)offer-far below the asking price.Surprisingly,they didn't laugh at us.They renewed their offer instead.It was also much more than we could afford,but far less than the original asking price.

The next day,we got a disappointing message that another buyer had offered a much higher price.Even so,we decided to talk with the owners directly.We made our final offer, which still was thousands of dollars 'less than' the other buyer's bid.We knew it,but we had to try.Nobody knew if we could get it.

Paragraph 1:We went to the owners' home after we made our final offer.The other buyer came to visit the owners too.

Paragraph 2:The owner looked at us and said,"I want to sell my house to you!"

Pushing people into ever-higher levels of formal education at the start of their lives is not the way to handle the problem. Just 16% of Americans think that a four-year college degree prepares students very well for a good job. Although a vocational education promises that vital first hire, those with specialized training tend to withdraw from the labor force earlier than those with general education perhaps because they are less adaptable.

At the same time on-the-job training is shrinking. In America and Britain it has fallen by roughly half in the past two decades. Self-employment is spreading, leaving more people to take responsibility for their own skills. Taking time out later in life to pursue a formal qualification is an option, but it costs money and most colleges are meant for youngsters.

The market is innovating to enable workers to learn and earn in new ways. Providers from General Assembly to Pluralsight are building businesses on the promise of improving careers. Massive open online courses (MOOCs) have turned away from lectures on Plato or black holes in favor of courses that make their students more employable. At Udacity and Coursera self-improvers pay for cheap, short programs. By offering degrees online, universities are making it easier for professionals to polish their skills. A single master’s program from Georgia Tech could expand the annual output of computer-science master’s degrees in America by close to 10%.

Lifelong learning starts at school. As a rule, education should not be narrowly vocational. The curriculum needs to teach children how to study and think. A focus on “metacognition” (元認(rèn)知) will make them better at picking up skills later in life.

【1】Which is the reason why traditional education is failing?

A.It bursts educators’ bubble in the beginning.B.Companies can’t afford training fees.

C.Old skills can’t meet the present needs.D.It fails to develop one’s brain.

【2】What can we infer from the text?

A.The more knowledgeable one is, the more likely he is to be employed.

B.Most Americans are poor at their studies in the college.

C.More than 80% of Americans have to be self-employed now.

D.Returning to college after working is not considered worthwhile.

【3】What does the underlined word “innovating” in Paragraph 4 mean?

A.Reforming its system.B.Declining little by little.

C.Booming all at once.D.Wasting time and energy.

【4】How do colleges adapt to the present education model?

A.They open online courses.B.They provide easier access to updated skills.

C.They pay for cheap short programs.D.They lower the standard for master’s degree.

Our model of which a garden should be goes back to childhood. My sister and I like to visit Grandmother when we were young. After rushing out of car, we ran to our grandmother’s garden. It was interested that, with seasons changing, the garden would to take on different looks. They were neat paths and a wooden bridge over a pool. She used to keep a small garden, including ducks and another animals, but later she made it much large. Grandmother looked after the garden with great care. We often helped Grandmother grow several row of plants or pick vegetables. Being with her was real enjoyable. That’s our dream garden, a place full of love of Grandmother.

Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

Night milk quickened the start of sleep and caused the mice to sleep longer.

While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.
