    No one knows exactly how the earth began, as it {#blank#}1{#/blank#}(happen) so long ago. However, according to a {#blank#}2{#/blank#}(wide) accepted theory, the universe began with a “Big Bang” that threw matter {#blank#}3{#/blank#}all directions. After that, atoms began to form and combine to create stars and other {#blank#}4{#/blank#}(body). For several billion years after the “Big Bang”, the earth was still jus {#blank#}5{#/blank#}cloud of dust. What it was to become was uncertain {#blank#}6{#/blank#}between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so {#blank#}7{#/blank#}(violence) that it was not clear {#blank#}8{#/blank#} the shape would last or not. It exploded loudly with fire and rock. They were in time {#blank#}9{#/blank#}(produce) carbon, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even{#blank#}10{#/blank#}(important) is that as the earth cooled down, water began to appear on its surface.

    In the age of the smart phone, there seems no reason to ask questions about: the weather forecast, a business's phone number or directions, {#blank#}1{#/blank#} can be easily found on Google, but very often people {#blank#}2{#/blank#}(actual) ask these things by {#blank#}3{#/blank#}(make) a phone call. Your answer may be replied to with a thank­you e­mail. This isn't the first time that great changes {#blank#}4{#/blank#}(take) place in our manners due to technology. In {#blank#}5{#/blank#} late 1870s, when the telephone {#blank#}6{#/blank#}(invent), people didn't know how {#blank#}7{#/blank#}(greet) a caller. Often there is just {#blank#}8{#/blank#}(silent). Alexander Graham Bell, the inventor, suggested that people say "Ahoy", {#blank#}9{#/blank#} finally "Hello" went out. The greeting is now used in everyday face­to­face communications. Try to be respectful no matter who you communicate {#blank#}10{#/blank#}. Just keep it in mind that politeness never goes out of fashion.

    One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he {#blank#}1{#/blank#} (find) that he had run out of salt. So Nick called to his son, "Go to the village and buy some salt, but pay a fair price for it: neither too much {#blank#}2{#/blank#} too little."

    His son looked surprised. "I can understand why I shouldn't pay too much, Father, but if I can pay less, {#blank#}3{#/blank#} not save a bit of money?"

    "That would be a very {#blank#}4{#/blank#} (reason) thing to do in a big city, but it could destroy a small village like ours," Nick said.

    Nick's guests, {#blank#}5{#/blank#} had heard their conversation, asked why they should not buy sale more cheaply if they could. Nick replied, "The only reason a man would sell sale {#blank#}6{#/blank#} a lower price would be because he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect {#blank#}7{#/blank#} the sweat and struggle of the man who worked very hard to produce it."

    "But such a small thing couldn't {#blank#}8{#/blank#} (possible) destroy a village."

    "In the beginning, there was only {#blank#}9{#/blank#} very small amount of unfairness in the world, but everyone added a little, always {#blank#}10{#/blank#} (think) that it was only small and not very important, and look where we have ended up today. "

Many people think that fat-free cookies are a healthier option than a regular cookie, and that{#blank#}1{#/blank#}(choose) a salad is a much better choice than a cheeseburger. But in fact, there are a lot of foods considered as "healthy"{#blank#}2{#/blank#}are packed with hidden calories and sugar. Maybe you are trying your best to pursue healthier snacks,{#blank#}3{#/blank#}many choices are still harmful to your health.

Ideally, snack choices should be based{#blank#}4{#/blank#}the same principles as meal choices. After all, snacks make up an important part of people's daily food intake.

In addition, every person is unique. There isn't a{#blank#}5{#/blank#}(recommend) amount for snacking. It depends on a person's activity level, body size, medical situation, schedule and personal preferences. Some people{#blank#}6{#/blank#}(rare) snack at all, while others gain a{#blank#}7{#/blank#}(significance) part of their daily food intake from snacks throughout the day.

Keeping track of snacking habits can be beneficial, especially if you include notes that mention how each snack{#blank#}8{#/blank#}(contribute) to your personal goals. For example, if eating{#blank#}9{#/blank#}afternoon snack helps you avoid overeating at dinner time, then it may be a wise choice{#blank#}10{#/blank#}(make).
