As we all know there are all kinds of clubs in US middle schools, such as music club, sports club, chess club, swimming club. But do you know homework club? It is a popular club in many US middle schools. More and more students spend(花费) their afternoons at homework clubs. The US middle school students need a quiet place to study. But games, computers and TVs are all around kids at home. So the homework club is just for them to do their homework. The club is quiet and it's good for students to study. Some teachers are there, too. They can answer students' questions and help with their homework.

    After the students finish their homework, they can go home. Then they can play games or watch TV happily.

Last summer,Cathy's whole family went to New York City for their summer vacation. They stayed there for two weeks.

New York City has more than seven and a half million people.{#blank#}1{#/blank#} It is also the home of the United Nations.

First they visited the Statue of Liberty. The Statue of Liberty is one of New York's most well-known places.{#blank#}2{#/blank#} On the second day they went to the Empire State Building. {#blank#}3{#/blank#}From the top of the building, they saw most parts of New York. On the third day they visited the Metropolitan Museum.{#blank#}4{#/blank#} During the rest time of the week, Cathy went to Bronx Zoo with her younger brother and sister. There they were glad to see a lot of their favourite animals-tigers, lions, monkeys, and elephants.

{#blank#}5{#/blank#} On the island, they spent most of their time swimming sunbathing and playing on the beach. They all had a good time.

    In my life, the person who has influenced me most is my father. He is a role model for me. Now I'll tell you something about him. My father is in his{#blank#}1{#/blank#}(fifty). He never smokes or drinks. He{#blank#}2{#/blank#}(work) in a local factory for years. You will not find anything{#blank#}3{#/blank#}(usual) about him until you learn more. He works{#blank#}4{#/blank#}(care) all the time, so he{#blank#}5{#/blank#}(respect) by his colleagues. My father has always been kind and helpful. He has fun{#blank#}6{#/blank#}(talk) with old people. He gave our TV to a family who could not afford one. He cares for the children who have lost their parents. Whenever he has some money left, he {#blank#}7{#/blank#}(give) it to someone in need.

    My father has donated blood many times since we{#blank#}8{#/blank#}(move) here. The blood he has donated is much enough{#blank#}9{#/blank#}(save) over 70 lives. He has donated blood cells to people with blood cancer. To my surprise, he has decided to donate his body for medical research after his{#blank#}10{#/blank#}(die).

    When I was a little girl, I could not understand why my father always seemed to be{#blank#}11{#/blank#}(kind) to others than to his own families and why he thinks of others more than{#blank#}12{#/blank#}(he). Now I realise that he owns a heart full of love.

Astronauts would face dangers both getting to and surviving (生存) on Mars. Let's learn about surviving a trip to Mars.

What would it take to keep people safe and healthy on a trip to Mars? Scientists are already working on it, though the trip may be many years later.

Over the last 60 years, many spaceships have flown by orbited（沿轨道运行）and even landed on the Red Planet. However, machines cannot replace humans. That's why the United States, China and other countries want to send people to Mars. But surviving on this trip would not be easy.

A trip to Mars would be the farthest journey in human(人类) history. Mars is about 225 million kilometers away, so it would take astronauts at least 180 days to reach there. However, it only takes a few days to get to the Moon.

Space travel is dangerous. For one thing, staying in space for long periods makes the human body weak. Also, it puts pressure behind the eyes and causes eye problems. But gravity(重力) machines could help.

Then there's space radiation(辐射) to worry about. It is bad for astronauts when they have long journeys. Scientists are working out the issue. They have found that taking certain vitamins can help.

Astronauts will have to pack light to lift off from the earth. But they won't be able to get the things they need easily. Astronauts on the space station practice for this by growing lettuce and other food in space. Engineers are developing 3D printing techniques（技术）which can allow future Mars astronauts to build what they want.

Is your food and drink healthy? A lot of ice-cream, hamburgers and cola are unhealthy（不健康的）. Meat is healthy but too much meat is not good for children. Cola and candy are very sweet, and too much sugar is bad for you. Eat the right food and be healthy. Carrots, eggs and sweet potatoes are good for your eyes. Milk, cheese and fish are good for your teeth. A bit tired? Have lots of delicious chicken soup! It is important to remember: eat well, stay healthy, and don't get fat!

The following are some suggestions on healthy eating.

● Eat noodles or rice, not hamburgers.

● Have a good breakfast every morning.

● Drink juice, water, tea and milk, not cola.

● Eat lots of fruit and vegetables, not candy or ice-cream.
