My wife is addicted to shopping on the Internet. {#blank#}1{#/blank#} seems that she can't control herself well, just clicking constantly with the mouse. Let me tell you what happened last night. It was the fourth time she {#blank#}2{#/blank#}(shop) online for hours. I had already reminded her {#blank#}3{#/blank#}(think) twice before buying anything, but my wife ignored {#blank#}4{#/blank#}I said and replied confidently, “With the New Year {#blank#}5{#/blank#}(approach)”, preparation is necessary. Besides, I haven't bought things on the Internet for a whole week.” Hearing her words, I was really speechless. In most cases, the things she bought aren't good value for money. Maybe she just enjoys {#blank#}6{#/blank#}process of buying online.

    Nowadays, {#blank#}7{#/blank#} the development of technology, online shopping is becoming more and more convenient. Those {#blank#}8{#/blank#}stay at home can buy whatever they want. In the meanwhile, it causes a series of problems. One of them {#blank#}9{#/blank#}(be) more spending than before, because people are {#blank#}10{#/blank#}(easy) attracted by the discount. So how to keep a good state of mind in front of temptation（诱惑）is an important lesson many people need to learn.

    When China's astronaut Zhai Zhigang carried out the spacewalk on September 27, he was wearing a spacesuit developed by Chinese scientists. Being worth more than 30 million yuan, the Feitian (飞天) spacesuit is not {#blank#}1{#/blank#}ordinary one.

    It {#blank#}2{#/blank#}（take）Chinese scientists four years to develop it. But what is special about the suit? First Let's take a look at why{#blank#}3{#/blank#}（astronaut） need to wear spacesuits.

    When you visit a world with little or no atmosphere, not{#blank#}4{#/blank#}(wear) a spacesuit, the following things would happen:

    You would become unconscious within 15 seconds because there is no oxygen.

    Your blood and body fluids(液体) would “boil” and then “freeze” {#blank#}5{#/blank#} there is little or no air pressure.

    You would receive various types of radiation.

    You could{#blank#}6{#/blank#}(hit) by dust or rock that moves at high speeds.

So, to protect you{#blank#}7{#/blank#}these dangers, a spacesuit must:

    Have a pressurized atmosphere;

    Give you oxygen;

    Keep a(n) {#blank#}8{#/blank#}(comfort) temperature;

    Let you see clearly and move easily.

    The Feitian suit did all that and what it {#blank#}9{#/blank#}（do）made it like a mini-spaceship in{#blank#}10{#/blank#}the astronaut stayed alive in outer space and carried out tasks.

    The Great Wall of China{#blank#}1{#/blank#}(list) in the World Cultural Heritage(世界文化遗产) by UNESCO in 1987. Just{#blank#}2{#/blank#} a huge dragon, it winds up and down across deserts grasslands and mountains, covering{#blank#}3{#/blank#} (approximate)6, 700 kilometers from the east to the west of China.

    In ancient China, many people built walls around their states to protect their land. It was Emperor Qing Shihuang who had the walls{#blank#}4{#/blank#}(join) up. The project cost much money and hundreds of thousands of people worked on{#blank#}5{#/blank#} wall. On top of it, it is wide enough for five horses or ten men{#blank#}6{#/blank#} (walk) side by side. Along the wall are watchtowers, {#blank#}7{#/blank#}soldiers used to keep watch. With a history of more than 2000 years, some of the sections of the Great Wall are now in ruins or even disappeared. However, it is still one of the most{#blank#}8{#/blank#} (attract) spots around the world because of its wonderful buildings and historical{#blank#}9{#/blank#}(important). Many of the tourists have come to know the famous Chinese saying— "He who does not reach the Great Wall {#blank#}10{#/blank#} (be) not a true man.”

    If you're on a dark countryside hill some night, {#blank#}1{#/blank#} (look) up at the sky. A band (束) of light may appear that looks like milk spilled (洒落) across the sky. The ancient Romans called the band via lacteal which means "milky road" {#blank#}2{#/blank#} "milky way."

    The band of light that you see isn't actually milk, of course—it's a galaxy (星系). A galaxy can contain many millions of stars held together by the force of gravity. Our solar system, {#blank#}3{#/blank#} includes the sun. Earth, and other planets, is part of this galaxy called the Milky Way.

    The Milky Way {#blank#}4{#/blank#} (make) up of hundreds of billions of stars like our sun. And like our sun, most of these {#blank#}5{#/blank#} (star) have at least one planet moving around {#blank#}6{#/blank#} (they). Earth is located about halfway between the center of the Milky Way and its outer edge.

    At the center of the Milky Way is one of the {#blank#}7{#/blank#} (strange) and deadliest things in the universe: a black hole. {#blank#}8{#/blank#} (scientist) believe a black hole lies at the center of most galaxies. The Milky Way's black hole is called Sagittarius A*. Its gravity is {#blank#}9{#/blank#} strong that it pulls in anything that gets too close including stars. So we're {#blank#}10{#/blank#} (luck) that Earth is located far away from the center!

Up to 82 percent of children with healthy mothers are not easy to be obese(肥胖的), according to research. A mother, {#blank#}1{#/blank#} has a healthy weight, exercises regularly, eats a healthy diet, doesn't smoke and only {#blank#}2{#/blank#}(drink) wine in moderation, is significantly less likely {#blank#}3{#/blank#}(have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育){#blank#}4{#/blank#} nature, as a mother's lifestyle appears {#blank#}5{#/blank#}(direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity {#blank#}6{#/blank#}(reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine {#blank#}7{#/blank#} fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child {#blank#}8{#/blank#}(be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical {#blank#}9{#/blank#}(active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having {#blank#}10{#/blank#} obese child.
