We see with our eyes and taste with our tongues. Ears are for hearing, skin is for feeling and noses are for smelling. Would anyone say that ears can smell, or that tongues can see? Actually, yes. Paul Bach-y-Rita, a scientist at the University of Wisconsin, believes that the senses can changeable. For example, a tongue can be used for seeing. The brain, as we know, is a complex organ(复杂的器官). Even when part of it is hurt, it will try to carry out the same function by sending the function to another area of the brain.
A college student was asked to take part in an experiment. In the experiment, his eyes were covered with a small video camera. The camera was connected to a long plastic line which went into his mouth. A computer would change the video’s picture. The picture would travel through the plastic line as an electric current(电流), reaching the electrodes(电极板) inside the student’s mouth. The scientist would roll a ball towards his right side, left side, or centre, and the student would have to catch it. When the scientist rolled the ball, pain passed over the student’s tongue. For the position of the pain on the tongue, the student reached out his hand and caught the ball.
If the brain can see a ball through a camera and a wet tongue, blindness and deafness can be overcame.How many senses are talked about in the first paragraph?
| A．4. | B．5. | C．3. | D．2. |
What is the right order according to the experiment?
①The scientist rolled a ball.
② The student caught the ball.
③ The student felt pain on his tongue.
④The scientist connected the camera to a long plastic line.
| A．①②③④ | B．②①④③ | C．④①③② | D．④③①② |
What could be the best title for the passage?
| A．Senses Are Important |
| B．An Interesting Experiment |
| C．A Famous Scientist |
| D．Senses Are Changeable |

What would you do if you felt anxious（焦虑的）？Would you feel better if someone else could share his or her experiences with you？ In the United States，two teenage girls set up a mental health camp called" Healing（治愈） Hearts" to help people deal with anxiety．
The idea of creating the camp came from Dinah Martinez，17，and her schoolmate Janet Martinez，
18．Both girls suffered from anxiety．
Dinah Martinez always did well in school．" But then I just started to collapse（崩溃），" Dinah Martinez said．She stopped talking to her friends，stopped going to school for three weeks and stayed at home．
Janet Martinez was anxious in elementary school．Things got even worse in junior high．"It was a lot of pressure（压力）I put on myself．I would wake up in the morning and it was like my heart was racing，she said．
The girls' camp idea got support from Girls Leading Our World（ GLow）in the US．The organization awarded them ＄5，000 to put on the camp for other teenage girls．
The " Healing Hearts" camp was created to "help deal with anxiety，especially with girls in high school because that's when they are the most vulnerable（脆弱的），" Janet Martinez said．
On the first day of the camp，10 girls were there．Experts at the camp talked about anxiety．They
helped girls who were experiencing anxiety．The girls learned how to calm themselves when they are
anxious．They learned about calming methods like deep breathing and guided mediation （调节）．
" It's good to know that someone else is going through the same thing as me and we can both help
each other out，" Dinah Martinez said．

The human body is a machine that can raise lots of interesting questions．Why，for example，are yawns（呵欠）contagious（传染的）？What's up with ice﹣cream headaches？ Here are answers to these and other questions about our bodies．
Why do I get a headache when I eat ice cream too quickly？
Scientists aren' t exactly sure what causes the brain freeze when we eat ice cream or other super﹣cold foods too quickly，though some believe it's the result of changed blood flow in the nervous stem．Blood vessels in the head tighten to stop the loss of body heat and then relax to let blood flow rise；that sudden rush of blood is what causes the headache．You can improve an ice﹣cream headache by rapidly rubbing your tongue across the roof of your mouth to help warm up things．
What causes my stomach to make a low continuous noise when I'm hungry？
Actually，your stomach makes noise whether you're hungry or full；you just hear it more clearly when you're hungry．Think of your digestive tract（消化道）as a really long tube lined with smooth muscle tissue． These muscles move food，fluids and gas through your digestive tract． A ．It can make you feel embarrassed（尴尬的） but is nothing to worry about．
Why do I blush when I'm embarrassed？
When you're embarrassed，your brain releases a shot of adrenaline（肾上腺素），which makes your heart race and blood vessels become larger in size．All this happens to increase blood flow and oxygen delivery throughout the body in a fight﹣on﹣ flight reaction（对抗反应）．There are a lot of tiny blood vessels in your face，which turn noticeably redder from this sudden rush of blood．As for the actual function of blushing，researchers are still trying to find that one out．
Why are yawns contagious？
Have you ever yawned in front of someone，only to have them yawn right back？ It's a common thing but researchers don't have a good explanation for it．They do，however，know this happens only with humans and chimpanzees（ 黑猩猩）．A bigger question puzzling scientists is why we yawn at all It used to be thought that yawning showed that oxygen to the brain was not enough，but that's just a myth．A growing body of research now shows that yawning is nature's way of keeping our brains cool．

You think it's " cool " to carry your backpacks and head out to school．But if you don' t know exactly how to choose，load，lift and wear them﹣these all﹣important accessories（配件）can be a pain in the back．Not to mention the neck，head and shoulders．
Backpacks can influence your health．Carrying a heavy load improperly can lead to
poor body position；and even hurt the spinal column（脊柱）．This can cause muscle strain，headaches，back，neck and arm pain．
For example，if it is carried on one shoulder，a heavy backpack forces the muscles and spine to balance the unequal weight．This may increase the possible back problems later in life．
More than 50 percent of young people suffer back pain by their teenage years．Research shows that this could be mainly caused by improper use of backpacks．
Here's some advice to help you carry backpacks comfortably and safely．
Choose the right backpack．Forget leather（皮革）! It looks great，but it's far too heavy．Go for canvas（帆布）．Pick a pack that has two wide，adjustable，comfortable shoulder straps（带子），along with a hip or waist strap，and plenty of pockets．Make sure the pack fits properly and its size is suitable for the wearers body．
Packing it properly．Only put in the pack what is needed for that day．It's a good idea to know what each object weighs．The total weight of the filled pack should be no more than 10 to 15 percent of the wearer's own body weight．Pack heaviest objects close to the body，and place little ones outside， away from the back．
Putting the backpack on．Put the pack on a smooth surface，at waist height．Put on the pack，one shoulder at a time，then adjust（调整）the straps to fit comfortably．Remember when lifting a backpack， or anything，to lift using the arms and legs and to bend at the knee．
The right way to wear a backpack，Both shoulder straps should be used，and adjusted so that the pack fits the body，without hanging to one side．Backpacks should never be worn over just one shoulder．You should be able to move your hands between the backpack and your back．The waist strap should also be worn．
