People often believe that certain harmless snakes are poisonous. Try to find out which of the snakes in your ares are truly poisonous and which are not. Please do not kill non-poisonous snakes, because they do no harm. On the contrary, they kill mice and other pests that do lots of damage. Some even kill poisonous snakes.

Here is some treatment for poisonous snakebite:

*Stay quiet: don’t move the bitten part. The more it’s moved, the faster the poison will spread through the body. If the bite is on the foot, the person should not walk at all. Send for medical hep.

*Remove jewellery because swelling can spread rapidly.

*Wrap the bitten are with a wide elastic bandage or clean cloth to slow the spread of poison. Keeping the arm or leg very still, wrap it tightly, but not so tight that it stops the pulse（脉搏）at the wrist or on top of the foot. If you cannot feel the pulse, loosen the bandage a little.

*Wind the bandage over the hand or foot, and up the whole arm or leg. Make sure you can still feel the pulse.

*Carry the person, on a stretcher（担架）if possible, to the nearest health center. If you can also take the snake, because different snakes may require different antivenoms（抗毒血清）.

*Poisonous snakebite is dangerous. Send for medical help----but always do the things explained above at once. Some treatments, such as cutting the skin around the bite and sucking the venom out of the bite, can cause infection. And remember: Never drink alcohol after snakebite. It makes things worse!

As is known, some students have breakfast regularly. Therefore, others don’t, or even skip it. Among of the students who have breakfast every day, only a few have a balanced diet which includes breads, milk and eggs. There is several reasons. First of all, many students don’t know an importance of breakfast. Besides, many parents have limited knowledge about that a balanced diet is. Finally, teachers give students too much tasks, so they have no time have breakfast. In a word, every student should had breakfast regularly. The more balanced diet one has, the healthy he will be!

It is important for parents to know how to help their kids eat healthy. Here are a few easy ways:

Parents control the supply lines.

【1】 Though kids may keep asking for less nutritious foods, parents should decide which foods are regularly provided in the house. Kids won’t go hungry. They’ll eat what’s available in the fridge at home.

Say goodbye to “clean-plate club”.

【2】 Lots of parents grew up under the clean-plate rule, but that way doesn’t help kids listen to their own bodies when they are full. When kids feel full, they’re likely to overeat.

【3】

Food preferences are developed early in life, so try to offer different kinds of food. Likes and dislikes begin forming even when kids are babies. Parents may need to serve a new food on several different occasions(时机) for a child to accept it.

Food is not love.

Find better ways to say “I love you.” When foods are used to reward kids and show love, they may start to turn to food when feeling worried or unhappy. 【4】

Kids do as you do.

【5】 When trying to teach good eating habits, try to set the best example. Choose nutritious food, eat at the table, and don’t forget breakfast.

A. Start them young.

B. Rewrite the kids’ menu.

C. Be a role model and eat healthy yourself.

D. Offer praise and attention instead of food treats.

E. Let kids stop eating when they feel they’ve had enough.

F. You decide which foods to buy and when to serve them.

G. Let kids choose what to eat and how much of it they want.

As the species migrates (迁徙) from Central Asia to Southeast Asia every autumn, it must cross over the Himalayan range. These mountains force the bar-headed goose to fly at around 30,000 feet above sea level, which is the highest altitude for migratory birds.

These geese have special adaptions that allow them to survive at the altitude. For example, a special protein (蛋白质) in blood cells that transports oxygen throughout the body allows their blood cells to combine with oxygen. Their circulatory system provides a constant supply of fresh, oxygenated blood to their wing muscles (肌肉). They have much larger lungs than other birds, which give them the ability to take in more air.

Scientists initially believe that the geese flow at an extremely high altitude for the full length of their migration. But later the data suggests that the birds use a much more effective way of travel. Instead of remaining at an extremely high altitude to fly over the mountain range, the geese hug the mountains, flying up and down depending on the obstacles (障碍物) in their way. This works better for them because they don’t have to use all their energy flying in an area with low oxygen; they can spend time flying at lower altitudes.

The geese also make use of nature to make this work easier. To fly down, they simply allow gravity to pull them. To fly back up, they make use of orographic (地形的) lift, which happens when flowing air meets an obstacle, such as a mountain. The mountain forces the air up, creating an upward draft. The birds take advantage of this draft, expending less of their own energy to fly up the mountain.

The way these birds have adapted to flying across the Asian continent during their annual migration is certainly an amazing way to see nature at work.
