Mr. Whitson taught sixth-grade science.In his first class,he gave us a __1__ about an animal called “cattywampus”,which died out during the Ice Age.He passed __2__ a skull (头盖骨)as he talked.We felt proud for feeling it,took __3__ and later had a quiz.

When my paper returned,I was shocked at the big red cross through __4__ of my answers.Why? I had written down exactly what he said.

Very simple.Mr. Whitson __5__.He had made up the story about the cattywampus.Needless to say,we were extremely __6__.

We could have _7__ him out,he said.__8_,he told us _9__ remains of the animal had ever been found at the very moment he was showing us the skull,_10__ a cat's.So,why didn't we __11__ his description(描述)about its color and other facts,especially the ridiculous(荒唐的)__12 _ he gave it? The zeros would be recorded in his __13__ book.He hoped we would learn something from this __14__.Teachers and textbooks were not always correct and we shouldn't let our mind sleep,but speak up what we thought _15__.

We _16__ our skepticism(怀疑主义)into other classed,but it caused __17__ for the teachers who weren't used to being challenged.I've kept in mind what Mr. Whitson gave me-the   __18__ to look people in the eye and tell them they were wrong.

Not everyone sees the __19_ in this.I once told a teacher about it and she was surprised,saying "He shouldn't have tricked(欺骗)you like that." I looked at her right in the __20__ and told her she was wrong.

Everybody hates rats.But in the earthquake capitals of the world-Japan,Los Angeles,Turkey-rats will soon be man's new best friends.

What happens after an earthquake? We send in rescue dogs.Why? Because they can smell people.Dogs save lives.They help rescuers to find living people.But dogs are big hand they can't get into small spaces.So now a new research project is using a smaller animal to save lives:the rat.

How does it work? First,the rat is trained to smell people.When this happens,the rat's brain gives a signal(信号).This is sent to a small radio on its back,and then the rescuers follow the radio signals.When the rat's brain activity jumps,the rescuers know that someone is alive.The rat has smelled that person.

Although there are already robots which can do this job,rats are better.Christian Linster at Cornell University—New York says,“Robots' noses don't work well when there are other smells around.Rats are good at that.” Rats can also see in the dark.They are cheaper and quicker to train than dogs,and unlike robots,they don't need electricity!

The “rat project” is not finished,but Julie Ryan of International Rescue Corps in Scotland says,“It would be fantastic.A rat could get into spaces we couldn't get to and a rat would get out if it wasn't safe.” Perhaps for the first time in history,people will be happy to see a rat in a building(but only after an earthquake,of course).

A three-year-old kid pressing all the right buttons used his mother's computer to buy a second-hand Japanese car on the Internet auction(拍卖)site eBay.

The parents of the boy,Jack Neal,were dumbstruck when the website sent them a message of congratulations for buying the Barbie pink Nissan Figaro,a collector's item.

“We couldn't understand what was happening.Neither of us had bought anything,” said Jack's mother,Rachel,36.“So we checked and saw it was a Barbie pink car which we'd bought for 8,999 pounds.We flew into a panic(恐慌).

The following morning,Jack told his parents,“I've bought a car.”

Rachel Neal said she thought she had left her eBay password(密码)in her computer.“Jack's good at computers and just pressed all the right buttons,” she added.Her husband John,37,explained it had all been a mistake when he called the seller of the soft-top,second-hand car.“Luckily he saw the funny side and said he would re-advertise,” Rachel Neal added.

Paul Jones,co-director of Worcester Road Motors who is selling the car,said he had been amused by the bid(出价).“I had a phone call explaining what had happened and as soon as I heard it was a young boy who had done it by mistake I canceled the bid and re-advertise the car which is very collectable,” Jones said.“He must have good taste in cars.We've all got children and they do silly things at times so it was no problem.”

The car,which had been imported from Japan,is available on eBay at a starting price of 7,999 pounds or a buy-it-now price of 8,999 pounds.

Celia was shocked.She had always been in good shape during high school,but now,in her first year of college,she was suddenly ten pounds heavier.“My friends and I often had pizza or ice cream when we studied late at night,” she said,“and I was always drinking Coke to stay awake.”

Celia's experience is common.Many students enter college and find it so different that they cannot deal with changes properly.They're away from their parents and in a new stressful(压力的)environment.Pressures(压力)together with freedom to sleep and eat however they please cause many students to experience the “Freshman 15”:gaining weight suddenly in their freshman year of college.

Most students do not realize that the “Freshman 15” can cause some serious health problems.Of course,college-age adults are still developing bone mass,so gaining some weight is normal.Sudden weight gain,however,puts too much strain(负担)on the heart and lungs,resulting in little energy and some difficult thinking and remembering.In later life,it can lead to heart disease,diabetes,obesity,and possibly cancer.

The solution to the “Freshman 15” is simple-pay attention to developing good habits! In general:

●     Eat normal-sized meals at regular times.Eat slowly and enjoy it,so you don't need to go back for more.

●     Keep only healthy snacks in your room-and don't snack too often!

●     Control drinking and smoking.Alcohol has a lot of calories,and smoking too much makes exercise difficult.

●     Exercise regularly! Even just 30 minutes a day-such as walking quickly to class from your dorm—will make a big difference!
