Many people believe that, by the year 2100, we will live on the planet Mars(火星). Here is what life could be like.
    First of all, transport should be much better. By 2100, spaceship can travel at half the speed of light. {#blank#}1{#/blank#}
    Secondly, humans need food, water and air to live. Scientists should be able to find plants that can grow on Mars. These plants will provide us with food and air.
{#blank#}2{#/blank#} We could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
    Life on Mars will be better in many ways. {#blank#}3{#/blank#} It is possible to live in a large building with many bedrooms. Then, robot will do most of the work, so we have more time for hobbies.
{#blank#}4{#/blank#} Every student can study, do their homework on the computer and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
    However, in some ways, life on Mars may not be better than that on the earth today.  {#blank#}5{#/blank#} Meals will probably be in the shape of pills(药片) and will not be as delicious as they are today. Also, space travel will make many people feel ill.

Many people like{#blank#}1{#/blank#} . Children like animals{#blank#}2{#/blank#} . Usually we can only see dogs, cats, ducks or chickens around us. We{#blank#}3{#/blank#} see other animals such as elephants, tigers, pandas or monkeys. On Sunday, {#blank#}4{#/blank#} often take{#blank#}5{#/blank#} children to the zoo. How happy the children are! They{#blank#}6{#/blank#} from one place to another. They give animals all{#blank#}7{#/blank#} of good food to eat.
They{#blank#}8{#/blank#} there hour after hour. They don't want to go{#blank#}9{#/blank#} . Children {#blank#}10{#/blank#} have a good time in the zoo.

    Animals are {#blank#}1{#/blank#} (people) friends. But many wild animals are {#blank#}2{#/blank#}(face) the danger of{#blank#}3{#/blank#}(die) out. There're many reasons. First, their living environment change a lot because of the {#blank#}4{#/blank#}(develop) of many cities. Also, {#blank#}5{#/blank#}(pollute) becomes worse and this make wild animals lose {#blank#}6{#/blank#}homes. Second, some people are killing animals {#blank#}7{#/blank#}getting their fur, skin, teeth and meat.

    People should do something to help protect {#blank#}8{#/blank#}(endanger) wild animals. For example, people can build some nature reserves to save wild animals' homes. Animals can live {#blank#}9{#/blank#}(free) there. Besides, people are not allowed {#blank#}10{#/blank#}kill wild animals. If we start protecting our animal friends, our world will become much better.

    There are a number of ways to help improve your memory, so you shouldn't{#blank#}1{#/blank#}sad.

    My first way is that if you want to remember something, you have to review it{#blank#}2{#/blank#}.You may want to go over the material two days after you have{#blank#}3{#/blank#}it, then a week later, then two weeks later, and then a month later. After a month you will find that you can remember the material.

    My second{#blank#}4{#/blank#}is to use a colored pen to highlight(用颜色标出) the important parts on your book. This will help you in two ways. First, it will help you focus on the{#blank#}5{#/blank#}parts when you learn the knowledge. It is always{#blank#}6{#/blank#}than remembering everything.{#blank#}7{#/blank#}this will make reviewing better. When you open your book, the color parts will show you the most important things immediately.

    Another good time for remembering information is in the morning because you have just {#blank#}8{#/blank#}the whole night and your brain is fresh and clear. So it's easy to remember the important information in the morning.

    We can't remember{#blank#}1{#/blank#}(clear) since when we started to take our mobile phones to a dinner table. This happens a lot, especially when we eat out. Once d{#blank#}2{#/blank#} come, we take out our mobile phones and take photos i{#blank#}3{#/blank#}of lifting our chopsticks. Later, we post the photos onto Weibo or Wechat, {#blank#}4{#/blank#}(wait) to be "liked”. Then we checked our mobile phones from time to time during the meal, to see w{#blank#}5{#/blank#} we get “liked” or not. We just cannot leave our mobile phones for simply a meal.

    Does that sound familiar to you? Do you do that often? If not, how do you feel when others do that when having dinner with you?

    A recent study {#blank#}6{#/blank#}(suggest) that what we are used to doing is not that good. Spending time taking photos of food makes the food less pleasant So, w{#blank#}7{#/blank#} not stop taking photos and just enjoy the food ahead of you?

    Besides the {#blank#}8{#/blank#}(science)result, there are also some other bad influences of taking photos of food before meals. After posting the photos onto the Internet, one will be unable to control himself and check his mobile phone many times." Does everyone accept my photos? I hope a lot of people like them!" It seems like your mobile phone secretly calls your name all the time, even when you are w {#blank#}9{#/blank#}real people.

    So, next time you go out to have dinner, how about not taking photos of food? Let the food be delicious as it is and share your life with others. Trust me, and it will be a {#blank#}10{#/blank#}(wonder) time.
