    The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid-we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

    However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard(蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we'd need huge feet that we could bring up to our ears in order to create adequate "hitting."

    But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a tot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子) in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.

    Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink and take a shower afterward!

(1)、Walking on water hasn't become a reality mainly because humans         .
A、are not interested in it B、have biological limitations C、have not invented proper tools D、are afraid to make an attempt
(2)、What do we know about Basilicus basilicus from the passage?
A、It is light enough to walk on water. B、Its huge feet enable it to stay above water. C、It can run across water at a certain speed. D、Its unique skin keeps it from getting wet in water.
(3)、What is the function of the cornflour according to the passage?
A、To create a thick liquid. B、To turn the water into solid. C、To help the liquid behave normally. D、To enable the water to move rapidly.
(4)、What is the author's attitude toward the idea of humans' walking on water?
A、It is risky but beneficial. B、It is interesting and worth trying. C、It is crazy and cannot become a reality. D、It is impractical though theoretically possible.

When something is troubling us, it's natural to try and make it go away. We might head to the doctor or make a trip to the local drug store for medicine. Unluckily these methods can be expensive and it takes time.

But have no fear, because you might be able to come up with useful home remedies (治疗方法)with nothing more than a few simple ingredients from your house.

At one time or another, it seems everyone comes down with the flu. Along with taking it easy and getting plenty of rest, you can tur to chicken soup to make you feel better. Mothers from around the world have been making it for thousands of years for sick relatives. The hot soup warms you up and its pleasant smell helps to clear up your nose. It's often prepared with onions, carrots ... which all provide vitamins.

Nothing drives people mad quite like getting the hiccups (打嗝). In some cases, nothing seems to drive them away. Next time you've got a bad case of the hiccups, try this sweet solution. Take a full teaspoon with sugar and swallow it down. The sugar is thought to get your throat muscle (肌肉) to relax. Just don't overdo it, or you might have to take a trip to the dentist.

Headaches are another trouble. If you get one, try putting a pencil in between your teeth. A major cause of headaches is stress, and when we're worried, we often tighten our jaws (咬紧牙关), which pulls a muscle that connects to our head, and this action causes the pain, By placing a pencil in our mouths, we are giving our minds a signal to relax our jaws. This can reduce (减轻) the headaches almost immediately, But just remember not to bite(咬) it hard.

 阅读短文,从每小题所给的四个选项中,选出能回答所提问题或完成所给句子的最佳答案。

If you wake up one day and decide to build a house, how will you begin? Get some tools and build it at once? Or think carefully and prepare everything first? Of course, the second way is better. Why? Because you make a plan for your goal (目标)!

Many people have goals like getting better grades or finding a better job. But without a plan for reaching those goals, only 8 percent of these people will finally be successful. ____? First, it stops you spending time on meaningless things. Also, it helps you know better what to do step by step. What's more, if you make a good plan, you'll be surprised at how much you can reach. Last, by making a plan, you will know the problems you meet on the way to success and try your best to solve them.

The importance of having a plan is now clear, but do you know how to make your own plan?

Step 1: Put your goal down on a piece of paper. In this way, you will be more sure about it.

Step2: Cut your goal into small parts and make plans for them. So you will be clearer about what you can do step by step.

Step 3: Read your plan every day. Believe it or not, a plan is no good if you never look at it.

Step 4: Tell a friend about your plan. You may need his or her help when you can't follow it.

Remember: "A goal without a plan is just a wish." Once you make a plan for your goal and try your best to follow it, you will hardly fail.
