Traffic rules help to keep order on the road. They also help to keep people s{#blank#}1{#/blank#}. The pedestrian (行人) has as many rules to f{#blank#}2{#/blank#} as the driver of a car. You should walk on the sidewalk (人行道) or at the side of the road. Always look {#blank#}3{#/blank#} (careful) before you walk across the street.

    If you like riding {#blank#}4{#/blank#} bike, don't ride in the middle of the road or run through red traffic lights. When you ride a bike w{#blank#}5{#/blank#} a friend, don't look around or talk.

    If you drive a car, you should s{#blank#}6{#/blank#} down at the traffic lights. You must always wear a seat belt (安全带), Without belts b{#blank#}7{#/blank#} the driver and the passengers may be badly hurt in a sudden accident.

    You may not need to take a bus, but look out if you have to travel in one. Get on or get off a bus only when it comes to a s{#blank#}8{#/blank#}. When it is full, don't try to get inside, o{#blank#}9{#/blank#} you may fall off.

    Traffic rules are also {#blank#}10{#/blank#} (call) Road Safety rules. The maxim (格言) for all road users is "Thinking about others".

    Sometimes we meet people who change us. They bring magic(魔法) into our lives. Bridge to Terabithia (《通往特雷比西亚的桥》), the latest movie from Walt Disney, tells us such a story.

    Jess Aarons is a different kind of kid. He doesn't have too many friends in school. He is distant (疏远的) from his family as well. Jess wants to be the fastest runner in his school. He spends all of his time training for a race.

    But something strange happens. He's beaten, not by a boy but by a girl! As you might think, his pride is hurt.

    You wouldn't think Jess, and the girl, Leslie, would become friends. But the two kids open up to each other. Leslie shares her love of magic with Jess. Jess loves drawing. But before meeting Leslie he's never told anyone about it.

    Together they discover a secret world. They get to it by using a rope to swing across a river. There they fight against their enemies, from the Dark Master to school bullies (欺负弱小者).

    Can the kids beat their enemies? See the film and find it out for yourself.

Do you feel lonely when your best friend isn't around? Here's our advice to you—and to all kinds who feel lonely sometimes. 

It's hard when a best friend isn't around—maybe because he or she moved to a different school or a different class. You may feelleft out during break（间歇）or lunchtime. You want to make new friends, but how do you find them? Maybe it seems like everybody else already has his or her own friends. But remember, there's always room for more friends. 

Start by looking around your classroom—think about which kids you'd like to play with during break. Look for chances（机会）to say hi to them, smile, and be friendly. Offer（主动提出）to share something or express（表达）your appreciation（欣赏）to them. Invite someone to play with you or say "Do you want to sit here?" in the lunchroom. When you're at break, walk over to kids you want to play with, act（举止）friendly, and say "Hi, may I join you?" or just join in. 

If you have trouble（问题）doing this or if you're feeling shy, ask your teacher to help you make new friends. Teachers are usually pretty good at matching（相配）people up. The best way to make friends is to be a friend. Being kind, being friendly, sharing, saying nice things, offering help—pretty soon, you'll have one, or two, or even more new friends. 

You might still miss that special best friend. But when you see each other again, you can share something you didn't have before he or she left: You can introduce him or her to your new friends!

Spider monkeys are New World primates(灵长类). They get their names because they have very long limbs(四肢) and tails, which make them look like spiders. They are often seen with their limbs on different branches.

Spider monkeys can be in tropical forests of Central and South America, from southern Mexico to Brazil. They are 35 to 66 centimeters long and weigh 13 to 26 pounds. They have long tails that they use to catch tree branches, kind of like a 5th hand.

Spider monkeys live in groups. One group usually has dozens of spider monkeys. They communicate with each other through screeches (尖叫声). At night, spider monkeys break off into smaller sleeping parties of about half a dozen or fewer. Unlike many other primates, males (雄性) stay together throughout their lives with the females. They leave their first groups to find another group.

When they go out to look for food, spider monkey groups take separate actions in order to avoid competition for it. They mainly eat fruit and nuts. They also eat other things like insects, honey, leaves, spiders and bird eggs. Spider monkeys actually play an important part in the spreading of seeds throughout the South American rain forests. Enemies that they need to keep an eye out for include animals like lions and crocodiles.

Spider monkeys are dying out. Woodcutting, which leads to the loss(丧失) of their natural living places, is playing a big role in their loss. These monkeys are also hunted for food, or to sell as pets. Spider monkeys are actually one of the most popular monkey pets around because of their look and their behavior. We must do something to protect them. After all, such good and interesting monkeys should live with humans for many years to come.

Leeks are so common that you have probably never thought much about them. They grow easily in our gardens and don't look very special, but that doesn't mean they are not interesting! Leeks belong to the Allium family of vegetables, which also includes onions. Like onions and other members of the Allium family, leeks are a kind of vegetable with white soft parts and leafy green tops. The bulb(鳞茎), however, is not round, but just slightly larger than the stem nearest the roots. The more rounded the bulb, the older the leek. Leeks are usually about 30 cm long, but they can grow much bigger. Do you know growing leeks can win you a prize? Some gardeners grow big leeks and hold competitions to find the biggest type of leek. The heaviest leek ever weighed more than 8 kg. 

People have been eating leeks for thousands of years. The Ancient Roman Emperor Nero ordered his cooks to serve him leeks every day, as he believed they would improve his singing voice! People in Wales loved leeks so much that they made them their national symbol. As the story goes, about 400 years ago, Welsh soldiers were fighting in a war. They put leeks in their hats so that they could tell their friends from their enemies. 

Leeks are especially loved by cooks all over the world, as they give flavor(味道) to lots of dishes. Leeks taste a bit like onions, but their flavor is much weaker. They taste especially good in soups. In France, a leek and potato soup is eaten cold. Leeks go well with meat. 

So now we know that leeks are delicious, but are they good for you? Yes! Leeks are full of iron(铁). Experts now believe that eating leeks and other members of the Allium family can also help people keep their blood pressure under control and their hearts healthy.
