    Homework is a problem for students all over the world. As a student, you have a lot of homework to do every day. {#blank#}1{#/blank#}. And it helps you understand important knowledge. Luckily, there're several things you can do to make homework less difficult.

    {#blank#}2{#/blank#}. Write your homework down in your notebook if you need to. Don't be afraid to ask questions about it. Understand why you should do your homework.

    {#blank#}3{#/blank#}. Many schools have study halls. The students can study there. It's more interesting to play with your friends. But the more homework you finish at school, the less you'll have to do that night at home.

    {#blank#}4{#/blank#}. It is difficult to hold your attention for too long. So take some breaks while doing your homework. Taking a 15-minute break every hour is a good idea for most people.

    {#blank#}5{#/blank#}. If you don't finish your homework at school, think about how much you have left. It's a good idea to make a homework plan, especially when you want to enjoy sports or other activities.

    Experts in nutrition(营养) suggest that we should eat at least five different kinds of vegetables and fruit a day. They are very necessary for our health and help our bodies work well. They can help reduce (减少) the risk of getting ill. There are a lot of vegetables and fruit to choose from and they taste delicious. {#blank#}1{#/blank#}

    It's easy to buy our food from the local supermarket, so why do we go to the trouble of growing our own? Here are several good reasons: 

{#blank#}2{#/blank#} You can pick and eat it at once. When you have tried it, you will agree that vegetables and fruit that are eaten straight from the garden taste better than anything you can buy in a supermarket.

    You may want to cut down on your "food miles"-the distance that a product has travelled before it reaches your kitchen. Many food packages are flown halfway across the earth. {#blank#}3{#/blank#}

    Homegrown food is likely to be healthier. Food producers often use fertilizers(化肥) and pesticides (农药) which can end up in your food. If you grow your own, things are different.{#blank#}4{#/blank#} You might also choose to grow some traditional vegetables and fruit. These often have more of the vitamins, minerals(矿物质) and protein(蛋白质) that keep you healthy.

    {#blank#}5{#/blank#} And you can grow your own even if you only have a small backyard or a balcony(R E). Some food can grow well in pots, including lettuce, tomatoes, potatoes and carrots. You can recycle plastic bottles and cups to grow something. Just make sure there are holes for drainage (排水) and a small plate under them to catch drops of water.

Happy gardening!

    How important is your appearance? Although everyone wants to be good-looking, are beautiful people always happier people? For example, it must be a problem to be a really beautiful woman, because some people may be more interested in looking at you than talking to you. They think of you as a picture rather than a person.

    Some people think that women who are exceptionally(格外地) pretty and men who are particularly handsome must be stupid. They believe that only unattractive(无魅力的) people can be intelligent(智慧的).

    On the other hand, no one wants to be really ugly, and have a face that even your mother doesn't want to look at; and no one wants to be plain, either--that is, to be neither attractive nor unattractive, and have a face that is easily forgotten. Being attractive is like being rich. It can help you find happiness, but it doesn't always make you happy.

    So maybe the best thing is not to worry too much about how you look, but simply try to be an interesting person. For interesting people have interesting faces, and interesting faces are almost always attractive.
