There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community（医学界）{#blank#}1{#/blank#}a method of fighting heart disease, has had some unintended side{#blank#}2{#/blank#}(effect) such as overweight and heart disease—the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required{#blank#}3{#/blank#}(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt{#blank#}4{#/blank#}(remove) from food, the food tastes as if is missing something. As {#blank#}5{#/blank#} result, people will eat more food to try to make up for that something missing. Even {#blank#}6{#/blank#} (bad),  the amount of fast food that people eat goes up. Fast food {#blank#}7{#/blank#}  (be) full of fat and salt; by {#blank#}8{#/blank#} (eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be {#blank#}9{#/blank#} (care) not to go to extremes. Like anything, it is possible to have too much of both, {#blank#}10{#/blank#} is not good for the health.

    As Victor Hugo once said, “Laughter is the sun that drives winter from the human face”, and up to now nobody {#blank#}1{#/blank#}(be) able to do this better than Charlie Chaplin. He brightened the lives of Americans and British through two world wars. He made people laugh at a time {#blank#}2{#/blank#} they felt depressed, so they could feel more content {#blank#}3{#/blank#}their lives.

    Charlie was born in a poor family in 1889. His parents were both poor music hall performers. You may find it astonishing that Charlie {#blank#}4{#/blank#}(teach) to sing as soon as he could speak and dance. Such training was common in acting families at this time,{#blank#}5{#/blank#}(especial) when the family income was often uncertain. Unfortunately his father died, {#blank#}6{#/blank#}(leave) the family even worse off, so Charlie spent his childhood {#blank#}7{#/blank#}(look) after his sick mother and his brother. By his teens, Charlie had, through his humour, become one of the most popular child{#blank#}8{#/blank#}(actor) in England. He could mime and act the fool doing ordinary everyday tasks. No one was ever bored watching him－his subtle acting made everything entertaining.

    With time{#blank#}9{#/blank#}(go) by, he began making films. He grew more and more popular as his charming character, the little tramp, became known throughout {#blank#}10{#/blank#}world.

    First, reading books {#blank#}1{#/blank#}(be) fun. You can always keep yourself {#blank#}2{#/blank#}(interest) and it can help you have an enjoyable time if you like reading. This is especially useful when the weather is bad. It is a {#blank#}3{#/blank#}(relax) hobby too.

    Next，you can read a book anywhere：in a car，in a waiting room, on a plane, in bed—even in the bath.{#blank#}4{#/blank#} you need is a book! Reading is a convenient hobby as it is easy to stop and then start again.

    Another good reason for reading books is {#blank#}5{#/blank#} it is useful. If you read as a hobby，you {#blank#}6{#/blank#}(get) better and better at it. This means that you will read faster and will become {#blank#}7{#/blank#}(good) at understanding what you read. As your reading improves, you will probably find your school work becomes much easier. Many school subjects depend {#blank#}8{#/blank#} good reading and, as you read you learn more and more.

    Good readers are most likely to be good {#blank#}9{#/blank#}(write), too. They are usually good at{#blank#}10{#/blank#}(spell) as well, and have more things to write about. Reading books is really a wonderful hobby.

    Roofs and windows of buildings aren't the only surfaces that can be used to produce solar power. In China,{#blank#}1{#/blank#}（construct）has begun of the country's first solar highway, in which solar panels are placed underneath transparent concrete.

    The solar highway is a 2 km stretch（一段）of road{#blank#}2{#/blank#}（lie）on the Jinan City Expressway, and it's divided into three layers. The see-through concrete protects a set of solar panels of two{#blank#}3{#/blank#}（size）. Beneath the solar panels{#blank#}4{#/blank#}（be）a layer that separates them from the damp ground.

    The road{#blank#}5{#/blank#}（it）has already been completed, and now it's only a matter of connecting the grid（输电网）,{#blank#}6{#/blank#}is expected to be finished by the end of the year alongside the completion of the Jinan Expressway's south section.

    This isn't the first solar road China has worked on. Earlier this year, the Qilu Transportation Development Group, also handling the Jinan Expressway solar road,{#blank#}7{#/blank#}（build）a 160-meter- long solar road in{#blank#}8{#/blank#}city of Jinan. It has the ability of heating up to keep the highway clear{#blank#}9{#/blank#}snow and ice* and is able to{#blank#}10{#/blank#}（wireless） charge electric vehicles. The new solar highway is expected to one day be equipped with the same features.

    It was the spring of 1943 during World War Ⅱ. Standing among hundreds of new {#blank#}1{#/blank#}(soldier)at Camp Grant, Sam, just 18 years old, waited as a truck slowly drove by. {#blank#}2{#/blank#} full field pack was randomly thrown to each soldier.

    Sam received{#blank#}3{#/blank#} (he). After he opened the pack and looked at the things in it, he was greatly{#blank#}4{#/blank#}(astonish). He found his last name, Litrenti, was marked on each thing in his pack. "How strange!" Sam thought. He didn't think the one {#blank#}5{#/blank#} threw the field pack to him knew who he was.

    So why was Sam's last name marked on the things? You may not believe it, but it was the field pack that his father {#blank#}6{#/blank#}(use)during World War I.

    Sam {#blank#}7{#/blank#}(certain) didn't know that when he received it. It wasn't until after the war {#blank#}8{#/blank#} he found out why.

    After the war, he talked {#blank#}9{#/blank#}that with his father. After {#blank#}10{#/blank#} (talk)for a while, Sam's father became sure that the pack once belonged to him.

    Both the father and the son couldn't believe that! What a coincidence!
