You are walking over the tan-colored（棕褐色的）sand of the empty desert when a rattlesnake appears out of the sand in front of you. Luckily it had warned you of its presence. Imagine if that same snake were moved to a green leafy rainforest. The colors that helped the snake blend into（融合）the desert would make it stand out against the green environment.
This just goes to show you that camouflage（保护色）doesn't work everywhere. Let's take a look at one animal species that is famous for changing over time to stay camouflaged: the peppered moth. Moth collectors in England noted that most peppered moths collected in the early 1800s were light gray peppered with bits of black. Many years later most of the moths collected were almost completely black. What could have caused the more common light colored moth to become rare?
During the 1800s, Europe and America experienced the Industrial Revolution. One of the new fuel sources that were heavily used during this time period was coal. As the trees darkened with soot（煤烟）, the light-colored moths were easier to see. They were eaten by birds more and more, while the rare dark colored moths blended in better on the darker trees. This made them have a higher survival rate and thus they were more likely to pass their dark colored genes onto their children. Over time, the dark colored moths became the more common of the two color forms. Natural selection favored the dark moths, so they were more successful after the trees changed.
Sound a little hard to believe? Well, more changes have come about since these conditions started to reverse（转变）, starting in the 1950s. Then, a Clean Air Act was introduced. Since that time, technology and cleaner burning fuels have started to decrease pollution in the areas where the peppered moth lives. The black soot no longer settles on the trees. As expected, the light peppered moth has recently been more common in the population. This is because it is better camouflaged.

For some years，my mother worked for a charity as President and Secretary.Selling raffle tickets(兑奖券) was her main means of bringing in the charity’s muchneeded funds.We girls would accompany her，selling tickets with great success.My father made and donated beautiful wooden toys，jewellery boxes and other lovely items as prizes.
Now my sister was always coming up with “good ideas”，most of which didn’t work out to plan.But that didn’t deter her.She had many just waiting to be tested.When she was eight and I was just five，we had a wonderful idea for a business adventure.We decided we would sell raffle tickets for charity，and that charity was us!
So one afternoon，we told our mother we were going to play in the park with our cousins as we did most days after school.But instead，we walked around the streets armed with a raffle book，a pen and a large cloth bag to carry the money.
We’d accompanied our mother many times when she sold tickets，so people were familiar with us when we appeared at their doors.Despite the blank looks they received when asking about the prizes on offer，they were very generous.Although there were no actual prizes，our mother’s previous track record enabled us to sell nearly the whole book of raffle tickets.
Like a little pair of lottery(彩票) winners，we walked home and proudly showed off our takings.But our enjoyment of this sudden wealth was shortlived，and our plans for spending it quickly failed.Our angry mother took us back to every ticket buyer，making us apologise and give the money back.Thankfully，our sweet neighbours didn’t make a big deal of our “clever” misbehavior and thus my mother’s
fundraising career could continue safely.We were taught a good lesson by our mother that day.Also I remember my sister’s entrepreneurial(企业家的) spirit dried up a bit after that.

Pumpkins of almost any variety have flesh high in fiber and beta carotene(β-胡萝卜素). But we don't eat the vast majority of the pumpkins grown in the U.S. Instead, we, of course, carve faces into them, light them and perhaps leave them to sit outside for days. And then we threw them. But could we be eating more pumpkins?
The Howden pumpkin-the most common variety for decorative uses-has been produced for its size, shape, color and having a handle-like stem for easy carrying, according to Katie Kammler, gardening specialist with the University of Missouri Extension. “If it was my choice, carved pumpkins are not what I'd want to eat,” Kammler says. Instead, she'd prefer one of the smaller and sweeter varieties-like the jack-be-little, Hubbard or kabocha, which have been selected over time for taste.
“You could puree(把……研成糊状) your pumpkin,” she tells The Salt by email. “If you go that route, I'd recommend using the puree for baking; sugar and spices will go a long way in improving the taste.”
Now, admittedly, eating your Halloween pumpkin this way means not carving it. So what if you have already carved it?
We asked the Food and Drug Administration (FDA) whether they recommended eating Halloween pumpkins. Spokeswoman Lauren Sucher said, “They may have been left outside for days and exposed to dirt and insects, and possibly wax and smoke. But we recommend that consumers who want to use their pumpkins for food set aside some parts, such as pumpkin seeds, and roast them soon after carving.”
But this doesn't mean after Halloween there aren't better things to do with your pumpkin than putting it in landfills(垃圾填埋地). Kammler says those in good condition make great farm animal feed.
Another suggestion from Chef Dan Barber. “Donate your pumpkin to compost(堆肥) at your local farmers' market. So if it doesn't feed us at least it's helping crops grow.”
1.What do we learn about the Howden pumpkin?
A.It is most suitable for Halloween. B.It is mainly used for food products.
C.It is more delicious than the jack-be-little. D.It is Kammler's favorite variety of pumpkin.
2.What does Kammler mainly tell The Salt?
A.How to puree your pumpkin. B.How to eat Halloween pumpkins.
C.How to cook uncarved pumpkins. D.How to improve the taste of pumpkins.
3.What is the FDA's attitude to eating carved Halloween pumpkins?
A.Disapproving. B.Dissatisfied.
C.Uncertain. D.Uncaring.
4.What should we do to deal with unwanted pumpkins according to the text?
A.Eat those in good condition. B.Bury them under the ground.
C.Sell them at local farmers' market. D.Give them to farms to improve soil.

阅读下面短文, 根据所给情节进行续写, 使之构成一个完整的故事。
It was late spring When my mom and I were driving through the countryside. Back then I was 13 years old and always felt unhappy with Mom. However, little did I know that this trip was going to be a special one.
A pot of flowers sat in her back seat, whose pleasant smell filled the car . Suddenly, in the middle of nowhere, my mom pulled over. “What are you doing? “I cried, fearing that the car had broken down and we’d be stuck there, so far from home. Fortunately, that wasn’t the case. My mom hopped out of the car, grabbing the flowers from the back seat. “It’ll just be a minute, ”she called back through the open windows.
Impatiently, I cast my eyes towards the edge of the road before they settled on a little sign showing that it was a nursing home. I looked back to the building, somewhat annoyed, as my mom reappeared empty-handed.
Before she started the car, curiosity drove me to ask, “Do you know someone there?” She shook her head. “Then what did you do with the flowers?” She smiled slightly, “I gave them to the receptionist（前台接待员）. ”“What？”She laughed at my confusion. “I told the receptionist to give the flowers to whoever needed them, especially those who haven’t received any in a while. ”
I kept silent for a moment. Not long after we went on with our driving, I spoke again, “Did you leave your name? “To this she answered instantly, “No. Leaving flowers there for someone who will appreciate them makes me feel good, which is enough of a thank for me. ”
Suddenly, still thinking about Mom’s deeds, I heard something burst loudly. It was our car that broke down! Nothing could be worse, because neither my mom nor I understood how to repair it, and we didn’t know where the garage was. It also seemed impossible to wait for any passerby, since we had seen so few along the way.
