Ask Dr？Jeffers	This month Dr．Jeffers is answering questions about the human brain and how it works．
Dear Dr．Jeffers， One of my colleagues，Felix Moeller，told me that scientists are learning to use computer to'read minds'．Is there any truth to this story？ -Jane Leon，New York，USA Dear Ms．Leon， Well，a lot of research is being conducted in this area，but so far，the brain scanning equipment and corresponding computer programs haven't been able to actually read thoughts．In one experiment，test subjects（受试者）were connected to scanning equipment and shown two numbers on a screen．They were then asked to choose between adding or subtracting（减）the two numbers．Using this method，researchers were able to follow brain processes and make the correct assumptions（假设）70percent of the time．It's not quite mind reading，but it's certainly a first step． -Dr．J．
Dear Dr．Jeffers， My three-year-old son loves it when I dig my fingers into his sides and tickle （胳肢）him until he laughs uncontrollably．The other day I noticed him trying to tickle himself but he couldn't do it．Why not？ -Glenn Lewis，Vancouver，Canada Dear Mr．Lewis， It's because of how the brain works．The brain is trained to know what to pay attention to and what to ignore．It causes us to ignore physical feelings we expect to happen，but it causes a mild panic reaction when there is an unexpected feeling．For example，you don't notice how your shoulder feels while you're walking down the street．But if someone comes up behind you and touches you lightly on the shoulder，you may jump in fear．It's that unexpected part that causes the tickle reaction． -Dr．J．

6．Microsoft founder Bill Gates has opened up about being a parent，stating that 13 is an appropriate age for a child's first cell phone．
     The 57-year-old，father-of-three，revealed on the Today Show that his children Jennifer and Rory were not allowed phones until their 13th birthday and his youngest daughter Phoebe is still waiting for one．
"We've chosen in our family that it's 13 where you get a phone，"the self-made billionaire explained．
    He said as a result his children often return home from school complaining，"All the other kids have it．I'm the only one without it．It's so embarrassing．"
    Asked if he keeps passwords to his son and daughters'email and Facebook accounts，Mr Gates said that he doesn't for Jennifer，16，who he describes as"independent"．
He admitted that monitoring online activity is"a very tough issue for parents now"．
    Despite their vast wealth Mr and Mrs Gates，who live in Lake Medina，just outside Seattle，Washington，have said they want to give their children as normal an upbringing（抚养） as possible．
    It was previously reported that their youngsters have to complete household chores and are given a modest amount of pocket money．
    And in 2010 Mr．Gates said that he intends to give most of his $61 billion fortune away rather than hand it down．"That wouldn't be good either for my kids or society，"he said．
    Also during the Today interview with Matt Lauer，Mr Gates，who stepped down from Microsoft in 2008 to concentrate on philanthropy（慈善事业），said that helping others gives him the same happiness as creating software．
"What you really feel is what you've achieved．If a piece of software gets out there and lots of people love it-it lets them get their work done in better ways-that's exciting，"he explained．
Mr Gates was previously the richest man in the world，but he got shifted down a spot in 2010 after he decided to give away 28 billion to good causes．

5．When the lazy days of summer arrive and the schedule is filled with swimming，camp，and family vacations，it can be a challenge to find time for learning．But kids'reading skills don't have to grow cold once school's out．Here are some ways to make reading a natural part of their summer fun：
Explore your library．Visit your local library to borrow books and magazines that your kids haven't seen before．Many libraries have summer reading programs，book clubs，and reading contests for even the youngest borrowers．With a new library card，a child will feel extra grown-up by borrowing books．
Read on the road．Going on a long car trip？Make sure there are some books at the back seat．When you're not at the wheel，read the books aloud．Get some audio books （many libraries have large selections）and listen to them together during driving time．
Make your own books．Pick one of your family's favorite parts of summer-whether it's baseball，ice cream，or the pool-and have your child draw pictures of it or cut out pictures from magazines．Stick the pictures onto paper to make a booklet and write text for it．When you're done，read the book together．Reread it whenever you like!
Keep in touch．Kids don't have to go away to write about summer vacation．Even if your family stays home，they can send postcards to tell friends and relatives about their adventures．Ask a relative to be your child's pen pal and encourage them to write each week．
Keep up the reading habits．Even if everything else changes during the summer，keep up the reading routines around your house．Read with your kids every day-whether it's just before bedtime or under a shady tree on a lazy afternoon．And don't forget to take a book to the beach！Just brush　the sand off the pages-it's no sweat!

1．Paracutin was born in Mexico in February，1943．At the end of one week Paracutin was 500feet high，and it is now over 9，000feet high．Today Paracutin is asleep．
What is Paracutin？It was the first volcano（火山） in the world which was seen from its birth right up to the present day．On February 20，1943，a peasant and his wife set out to work in their corn fields from the Mexican village of Paracutin．They were surprised to find the earth warm under their feet．Suddenly they heard noises deep in the earth and a small hole appeared in their field．In the afternoon there was a sudden loud noise and stones were thrown high in the air．The peasants ran from the field and turned to watch．They saw the birth of a volcano．
Large quantities of stone and lava（岩浆） broke out and a little hill began to form．By evening this hill was 100feet high and hot ashes（灰烬） were falling on the village．At night the strong light of the hot lava lit up the countryside．The trees near the village were killed and the villagers had to leave their houses．When the village was destroyed，its name was given to the volcano．The news quickly reached Mexico City，far to the east．Many people came to watch the scene．The volcano grew and grew for ten years and hundreds of square miles of forest were destroyed．Then Paracutin went to sleep．

19．"I'd like to be at a healthier weight，"a friend told me．"But we just don't have the money to buy expensive diet foods and there isn't enough money to join a gym．"Many people feel that way-that a healthy diet and exercise plan is out of reach because of their high cost．Don't lose hope!We'll be looking at ways to make healthy choices without spending too much money．
First you don't need to buy the expensive pre-prepared"diet foods．"Back in the early 1970s when I started housekeeping，90% of the food I bought was ingredients．Very few things were preprocessed （预处理的）．Now 90% of the food you find in the store is quick food．That's a bad thing．
Quick foods like boxed"just add hamburger"meals have had the fiber （纤维） removed to make them faster to prepare．Take a look at the label （标签） on that box．It often has low numbers listed under"fiber"because fiber takes longer to digest．If the low fiber meal is digested，the result is that your body begins to store fat．Besides，your body is short of nutrients （营养物质）．You will be driven to eat more to try to make up for the low quality of the food you are eating．
And then there are the chemicals the producers add to the quick meals to make them palatable．If not，the stuff would taste like cardboard and you wouldn't enjoy it．However，these chemicals certainly aren't good for your health．
What's the answer？Buy whole ingredients and give up the expensive，low nutrition，processed foods．Do the cooking yourself and you will have control over what is in your food-and it will cost less，too．
28．People who find it hard to get a healthier weight thinkD．

D．it takes longer to digest

31．The author suggests in the text that people shouldC．
A．control the amount of food
