We are often warned by our teacher not to waste precious (宝贵的)time, because time lost will never return. I think it quite true. What does time look like?  {#blank#}1{#/blank#}. Time is abstract (抽象的), so we have to think about it.

Time passes very quickly. {#blank#}2{#/blank#}.  It is because they don't know how to make use of their time. They waste it in going to theatres, cinemas and parks, and doing other things. Why do we study every day? Why do we work? Why do most people would rather take buses instead of walking? The answer is very simple. {#blank#}3{#/blank#}.

Today we are living in the 21st century. {#blank#}4{#/blank#}. When a person dies, his life ends. Since life is short, we must devote our time and energy to our study so that we may be able to serve the people well in the future. {#blank#}5{#/blank#}, for it does not only bring us failure but also does us other harm. If it is necessary for us to do our work today, let us do it today and not leave it until tomorrow.

Remember time is much more valuable (珍贵的)than money.

A. We look upon time as life

B. Nobody knows because we can't see it or touch it and we can't buy it with money

C. Some students say they don't have enough time to review all their lessons

D. Laziness is the thief of time

E. We wish to save time because time is precious

Dear Peter,

Welcome to our school!

Yours,

The polar bear lives inside the Arctic near the North Pole. It has a very warm coat because the weather is cold at the north of the Arctic. A grown﹣up polar bear is usually about three metres long，and weighs 450 kilos. The food of the polar bear i{#blank#}1{#/blank#}fish，seals and other sea animals. It can stand up on its back legs because it has very wide feet. It can use its front legs like arms. The polar bear can swim very well. It can e{#blank#}2{#/blank#}swim 120 kilometres out into the water. Some people kill the polar bear for its beautiful white coat. S{#blank#}3{#/blank#} are calling on people to protect polar bears. The governments of Canada，the USA and Russia say that n{#blank#}4{#/blank#} is allowed to hurt﹣polar bears now. They say that these beautiful animals are d{#blank#}5{#/blank#} out. 

Emilio Santana is a fourteen-year-old boy. He is a ninth grader. He spends two hours a day playing 1 every day. He has been preparing 2 something since the third grade. 

He was at the beach. A little girl at the beach was going to the 3 . She took her hat off and her hair went with 4 . She was so 5 and felt embarrassed (尴尬的), and that picture 6 in Emilio's mind for a long time. The young girl's struggle (挣扎) 7 him to do something helpful. He started keeping his 8 to help sick children. They have lost their hair because of illness. 

For many years, Emilio grew his hair 9 one goal (目标) in mind: to give it to people who need it and truly help someone. "Knowing that I could 10 a big part in somebody else's life and bring joy to them, it made me want to change other people's lives into 11 ones," he explained. 

Growing his hair wasn't always 12 . Emilio faced difficulties because he is an athlete (运动员). Keeping long hair while being active in sports was very difficult. He also heard bad words from 13 . "Even when I got some words like 'boys shouldn't have long hair' and things like that, I decided to do it because I get to see 14 smile and make his or her life better." Emilio said. 

He kept going even though he met many difficulties, and he 15 made his dream come true. His hair has been given to children with hair loss (脱发) for free. 

When I turned nine, my parents surprised me with a bird from a pet shop. I named him Bubba, and I was {#blank#}1{#/blank#}( excite) to have a new friend. 

But soon, the excitement went away. As a kid, I didn't know how much work it takes {#blank#}2{#/blank#} ( look) after a bird. My parents didn't know, either. Bubba lived in {#blank#}3{#/blank#} small, dirty cage. He couldn't fly around as he wanted. The bird ended up living a much {#blank#}4{#/blank#}( short) life than living in the wild. It's a sad story. {#blank#}5{#/blank#}( unlucky), it's a common story. Birds shouldn't be living in cages, but lots {#blank#}6{#/blank#} them do. Many people don't look after these birds {#blank#}7{#/blank#}( good) and they die young. 

A lot of people buy birds without thinking too much, just like my family did. Birds can get really sad and lonely in cages, and sometimes they even hurt {#blank#}8{#/blank#}( them) by pulling out their feathers. 

So, {#blank#}9{#/blank#} can we help? It's easy! Please don't go to the stores that just put birds in cages as {#blank#}10{#/blank#}( pet). And tell your friends and family that birds are for the sky, not for cages.
