15．"USA？Britain？Which country is better to study in？"We often hear such discussions．As China open its door，it is a dream for many Chinese students to study abroad．They want to learn about the outside world．
It's true that studying abroad can help students develop themselves．Their foreign language skills will be improved and it may be easier to find jobs．
But there are problems that should be consideed．Language is the first．Students must spend a lot of time learnng another language．
Students must also learn to live without parents'care and deal with all kinds of things they haven't to do before，like looking after themselves．There are reports about Chineses students abroad running into an ocean of difficulties and giving up finally．When they have to take care of themselves，it is hard for students to study well．
Finally，studying abroad brings a heavy burden to the family．For most Chinese parents，the cost of studying abroad is very high．But is it worth it？
We know that there are many famous people who have achieved success through their hard work in China．Liu Xiang is a good example．Once an American teacher invited him there，but he refused．He kept training hard with his Chinese teacher．He surprised the world when he won a gold medal at the Athens Olympic Games．So when you wonder which country is better to study in，think it again．

16．"We are reading the first page of a book whose pages are endless…"
    I do not know who wrote these words，but I have always liked them．Our life is just like the book．It tells us that the future can be anything we want to make it．We can take the bright，unknown，unclear future and carve （雕刻） out of it anything that we can imagine，just as a sculptor （雕刻师） carves a statue from a shapeless stone．
    We are all in the position of the farmer．If we plant a good seed （种子），we'll get a good harvest．If our seed is poor and full of grass，we'll get a bad harvest．If we plant nothing at all，we'll get nothing at all．
    I want the future to be better than the past．I don't want it to be unclear because of the mistakes which history is filled with．We should all care about the future because we will spend the rest of our lives there．
    The past is gone．Nothing we can do will change it．The future is before us．Everything we do will influence it．Each day brings with it new starts in our homes and in our business if we realize them．We are just at the beginning in every field of human effort．
