One kind of female butterfly mates only once in its life —and then closes its wings to avoid
"harassment" when pursued by persistent and unwanted males, a Japanese researcher said.
     Observations of the Small Copper Butterfly, a colourful orange and black butterfly, showed that some
females closed their wings when males flew by, but only when they were males of their own species, said
Jun-Ya Ide, an associate professor at Kurume Institute of Technology in Fukuoka, western Japan.
     "When we looked into why, the males were courting the females. They do this very stubbornly, so the
females sometimes try to get away-or prefer to stay unobserved," he added.
     Ide and his colleagues brought a model of a male butterfly near the females to test their reactions and
found that young females that had yet to mate kept their wings open, but those that had already mated
closed them.
     Not only can the persistent attentions of unwanted suitors harm the delicate females, fleeing from them
—with the male often in pursuit —uses up strength and can even shorten their lives, he added.
     "Closing their wings makes them less visible, helping them avoid communication with their own species. We figured they were trying to avoid harassment by males," Ide said.
1. What does the word "harassment" mean in the paragraph?
A. sexual invasion  
B. embarassment  
C. attack  
D. threat
2. Why some some females closed their wings when males flew by?
A. because the female butterfly mates only once in its life.
B. because they close their wings to avoid "harassment" when pursued by persistent and unwanted
males.
C. because they don’t like the male butterfly at all.
D. because they are afraid of the male butterfly.
3. According the the passage, which is correct?
A. The females closed their wings when males flew by.
B. The female butterfly mates only once in its life.
C. Only the model of a male butterfly can make the young female butterflies to keep their wings open.
D. Not only can the persistent attentions of wanted suitors harm the delicate females, fleeing from them
—with the male often in pursuit -- uses up strength and can even shorten their lives.

It’s a goal for millions and millions of families every year——keep the Christmas spending within a certain amount, but can still afford the gifts that your loved ones will enjoy. Never has this concern been greater in recent years than right now. Even so, there are several things that you can do to help.
Hit the sales.
No one wants to get up at four o’clock in the morning and fight to get the best deal on Black Friday, and it’s surely very tough to pick up the courage and get out there in the cold for a good deal, but sometimes——it can be well worth. Many retailers(零售商) offer specials all through the day——and some even offer online Black Friday specials, so you may still be able to get a great deal on Black Friday.
Pay close attention to advertisements.
Once the Christmas shopping season is coming, retailers hungry for business will do just about whatever to get you in the store. Pay very close attention to weekly advertisements of sales among the major retailers and you may be lucky enough to find different prices for the same thing in different shops.
Shop online.
Some of us don’t like running from store to store in order to get the best price on the perfect gift, and some of us don’t like to go out in the cold at all——thankfully for us, we can do online shopping.
The world of online shopping lets people visit all the major retailers as well as some specialty stores that could only be found on the Internet. Customers can find exactly what they are looking for, at the best possible price without ever having to leave the house. With traditional Christmas shopping consumers are sometimes limited to what’s left in stock if they wait too long to get to a particular store.

    Last night was the last game for my eight-year-old son's soccer team. It was the final quarter. The score was two to one, my son's team in the lead. Parents surrounded the playground, offering encouragement.
With less than ten seconds remaining, the ball suddenly rolled in front of my son's teammate, Mickey O'Donnel. With shouts of "Kick it!" echoing (回響) across the playground, Mickey turned around and gave it everything he had. All around me the crowd erupted (沸騰). O'Donnel had scored!
Then there was silence. Mickey had scored all right, but in the wrong goal, ending the game in a tie. For a moment there was a total hush.

The silence was finally broken when Mickey, his face filled with joy, hugged my son tightly and shouted, "I scored! I scored. Everybody won! Everybody won!" For a moment I held my breath, not sure how my son would react. I need not have worried. I watched, through tears, as my son threw up his hand in the classic high-five salute and started chanting, "Way to go Mickey! Way to go Mickey!"
