Most people are very familiar with the traditional cars being driven by burning fuel. And many have heard of electric cars,     1     are kind to the environment, but few people know about Tesla.

Tesla is a world-famous brand of an electric car made by Tesla, Inc.,     2     (devote) to the design and production of high quality luxury electric cars. Now it has become     3     second name for the electric car.

Tesla electric cars are     4    (wide) considered as the safest, the most luxurious and fashionable cars. They are free of pollution; they are quick     5     (speed) up and quiet to travel in. Furthermore, they’re easy to drive and comfortable to sit in. Their     6     (big) advantage is that once charged, they can travel as far as 500 kilometers.

Like many other new energy car makers, Tesla also     7     (come) across many barriers(阻碍) in terms of technology in the beginning, but they didn’t give up. They overcome the     8     (difficulty) one by one and eventually produced the first Roadster(跑车) successfully in 2008.

2010 was no doubt a vital year     9     Tesla, in which the company was successfully registered on the NASDAQ stock exchange(纳斯达克股票交易市场). Today, Tesla electric cars     10     (sell) all over the world. Most of their owners are buyers who are rich and crazy about protecting the environment.

Once upon a time, there was a man named Lazy. He wanted to have a big house and it took him over a year     1    (build) one. The house was so beautiful     2    all of his neighbors admired him very much.

But as time went by, his house started to have some     3    (problem). One day, an old neighbor went past it and said, “Your house is beautiful, but the grass in the yard is a bit overgrown.” Lazy answered quickly, “I know, but it’s OK. I     4    (cut) it tomorrow.”

A few days later, a mailman came by with a letter for Lazy. The mailman said, “Sir, your house is wonderful, but the windows are a bit dirty. You can make it more wonderful by     5     (clean) them.” Lazy replied reluctantly (不情愿地), “I know, but it’s OK. I will do that tomorrow.”

Weeks passed by. Lazy’s yard was in     6    mess. The paint was falling down and the windows were covered with dirt. One day, his brother came over to visit him. He was     7    (surprise) at what he saw and scolded him     8    (angry), “Lazy, I know why you’re called Lazy. You’re just like your name! What have you done for your house? It could fall apart at any second!”

Just the next day, after a heavy rainstorm, Lazy’s house fell down!

There are many Lazys around     9    (we). Are you lazy, too? Have you ever put off “something” to “tomorrow”, “next month” or even “next year”? It’s much better to just deal with things today     10    to wait until some imaginary (想象的) “tomorrow” that might not actually come.

The Silk Road derives (获得） its name from the profit-making trade in silk that     1     (carry) out along its length beginning during the Han Dynasty in China. The Silk Road trade played a significant role in the development of Eastern and Western civilizations, opening long-distance political and economic relations.

Though silk was the major item     2     (trade) from China, many other goods and ideas were exchanged, including religions, philosophies, scientific discoveries in astronomy and mathematics, and technologies like paper-making, printing and gunpowder.     3    , the Silk Road was a route not only for culture as well as economic trade among the civilizations that used it. Many artistic influences were also spread via the Silk Road, particularly through Central Asia,     4    Hellenistic (希腊风格的），Iranian, Indian and Chinese influences could intermix. Buddhist art represents one of the most vivid examples of this interaction. The     5     (mix) of Greek and Indian elements can be found in later Buddhist art in China and throughout countries on the Silk Road.

In     6     present day, trade takes places on the Silk Road on land and on its sea routes. There are several projects under the name of “New Silk Road”     7     (expand) the transport infrastructure in the area of the historic trade routes. The best known is     8    (probable) the Chinese Belt and Road Initiative. In June 2014,UNESCO listed the Chang'an-Tianshan corridor (走廊） of the Silk Road     9     a World Heritage Site. The UNWTO has been working since 1993 to develop     10     （sustain) international tourism along the route with the goal of promoting peace and understanding.

The Flynn effect，first described in the 1980s by researcher James Flynn，refers to the finding that scores on IQ tests       1    （increase）in the past century. One research paper，published by psychologist Lisa Trahan and her colleagues，combined the results of other     2    （publish）studies and found that IQ scores have indeed increased since the 1950s.    3    there have been exceptions，IQ scores have generally increased over time. Trahan and her colleagues observed，“The existence of the Flynn effect is     4    （rare）disputed. ”

Researchers have put forward several theories to explain the Flynn effect. One explanation has to do with improvements in health and nutrition. For example，the past century has seen     5    decrease in smoking and alcohol use in pregnancy，improvements in the prevention and treatment of     6    （infection）disease，and improvements in nutrition. As Scott Barry Kaufman writes for Psychology Today，“The Flynn effect serves     7    a reminder that when we give people more opportunities to prosper，more people do prosper. ”

Another explanation for the Flynn effect     8    （relate）to societal changes. In a TED talk，Flynn explains that the world today is “a world where we've had to develop new mental habits，new habits of mind”. Flynn has found that IQ scores have increased the most rapidly on questions that ask us to find     9    （similar）between different things，and more abstract types of problem-solving，both of     10    are things that we need to do more of in the modern world.

He was so unfit that, during his time at Ajax, Cruyff would hide in the woods     7     his teammates did running training, only rejoining them for the last lap. Mr Messi, by contrast, credits a mostly vegetarian diet with prolonging his career and has benefited from his club's focus on     8     science of nutrition, sleep and psychology.

This is     10     in Chinese culture, long noodles are a symbol that people will live long.

“He passed away today at 91 (due to illness) but his mission     3     (end) hunger will live on and his legacy     4     (remember) for generations,” it said.

Having spent over five decades in hybrid rice research, Yuan, an academician with the Chinese Academy of Engineering, has helped China work     5     great wonder-feeding nearly one fifth of the world's population with less than 9 percent of the world's total land.

Qu Dongyu, Director-General of the UN Food and Agriculture Organization, on Saturday expressed his sadness over Yuan's passing.
