4．Dear Highlights，
       My sister is always in a bad mood，which gets me in a bad mood．What should I do？
Tessa，Virginia
    It can be hard to be around someone who is in a bad mood．Since you can't change another person's mood，try to focus on what you can control：your own mood and reaction．
    You might find it easier to stay in a good mood if you leave your sister alone when she feels grumpy （脾气暴躁的）．The next time she is in a bad mood，go to a quiet place in your house．Read，exercise，draw，listen to music-do something that makes you feel happy．
    Your parents might have some good suggestions for you，too．

    In addition to practicing with teammates，you can work on drills on your own．
    Learning more about the sport may help too．Your coach can likely direct you to some good resources on skills development．

14．Humans have sewn by hand for thousands of years．It was said that the first thread was made from animal muscle and sinew （腱）．And the earliest needles were made from bones．Since those early days，many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency．
Charles Wiesenthal，who was born in Germany，designed and received a patent（专利权） on a double-pointed needle that eliminated（消除） the need to turn the needle around with each stitch （缝合） in England in 1755．Other inventors of that time tried to develop a functional sewing machine，but each design had at least one serious imperfection．A Frenchman Barthelemy Thimonnier finally engineered a machine that really worked．However，he was nearly killed by a group of angry tailors when they burned down his garment factory．They feared that they would lose their jobs to the machine．
American inventor Elias Howe，born on July 9，1819，was awarded a patent for a method of sewing that used thread from two different sources．Howe's machine had a needle with an eye at the point，and it used the two threads to make a special stitch called a lockstitch．（双线连锁缝纫法） However，Howe faced difficulty in finding buyers for his machines in America．In frustration，he traveled to England to try to sell his invention there．When he finally returned home，he found that dozens of manufacturers（制造商） were adapting his discovery for use in their own sewing machines．
Isaac Singer，another American inventor，was also a manufacturer who made improvements to the design of sewing machines．He invented an up-and-down-motion mechanism that replaced the side-to-side machines．He also developed a foot treadle（脚踏板） to power his machine．This improvement left the sewer's hands free．Undoubtedly，it was a huge improvement of the hand-cranked machine of the past．Soon the Singer sewing machine achieved more fame than the others for it was more practical，it could be adapted to home use and it could be bought on hire-purchase．The Singer sewing machine became the first home equipment，and the Singer company became one of the first American multinationals．
However，Singer used the same method to create a lockstitch that Howe had already patented．As a result，Howe accused him of patent infringement（侵犯）．Of course，Elias Howe won the court case，and Singer was ordered to pay Howe royalties（版税）．In the end，Howe became a millionaire，not by manufacturing the sewing machine，but by receiving royalty payments for his invention．

4．Which of the following is NOT TRUE according to the passage？B
A．Singer is an American inventor and manufacturer．
B．The Singer sewing company became more practical．
C．The foot treadle helped to make the sewer's hands free．
D．Singer made improvements to the design of sewing machines．
5．Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties？B
A．Because the judge was against Singer for his surly attitude．
B．Because Howe had already patented the lockstitch used by Singer．
C．Because Singer had borrowed money from Howe and never repaid it．
D．Because Singer and Howe had both invented the same machine．
6．Which of the following would be the best title for this passage？D
A．A Stitch in Time Saves Nine
B．The Case between Howe and Singer
C．Patent Laws on the Sewing Machine
D．The Early History of the Sewing Machine．

1．Narrow（狭窄的） streets easily cause many traffic accidents．

18．With global warming and melting ice，it isn't easy being a polar bear anymore．Some studies have predicted that polar bears could die out by the end of the century．The good news is not all researchers think the bears are absolutely disappearing．Scientists at the American Museum of Natural History（AMNH） have published a new paper indicating that things might not be as bad for polar bears as some scientists expect．
To understand the reason for the researchers'cautious optimism，we must first understand the factors that are threatening the polar bear's existence．Polar bears consume a diet of mainly young seals．In order to hunt these seals，polar bears need to rest at the top of sea ice---the same ice that is increasingly melting for most of the year thanks to climate change．In another 50years，experts expect that the Arctic will be too warm for sea ice to form for half of the year，leaving polar bears without a reliable food source and in serious danger of starvation．
As it turns out，alternative food sources for the polar bears aren't completely out of the question．For as long as biologists have tailed after the animals，they've seen polar bears eating animals found on land like caribou（驯鹿） and snow geese---as well as the snow geese's eggs．
Can polar bears actually survive off these alternative food sources for long periods of time？To figure this out，researchers calculated the nutrients that a caribou and snow geese diet would provide．They found that even adult male polar bears would be able to obtain more calories than they would burn in hunting these meals．Moreover，the food would provide the food necessary to avoid starvation during the summer months．
Unfortunately，not all polar bears have tended to seek food on land．That said，the researchers expect that necessity would push more polar bears to hunt on land to avoid starvation．They also expect that the bears could learn from their fellow bears how to hunt on land until the practice becomes second nature．

19．There is a time when Karyn Bosnak couldn't pay a＄59bill at the grocery store．She was officially broke．She didn't have enough money to get on the subway，but she looked rich．She was a television producer，earned＄900a week，and had a closetful of designer labels like Gucci and Louis Vuitton．But she also had a＄20，221.40credit card bill and an empty bank account．Karyn decided that it was time for a change．She built a website and simply asked people to help her out by sending her a dollar or two．
On the site，Karyn honestly explained her situation．"If 20，000people gave me just＄1，I'd be home free．"Amazingly，it worked．Her website was visited by more than a million people．Although most donors just gave a few dollars，one generous donor sent＄1，000．She was on TV and in newspapers and magazines．She was offered a book deal and a movie contract．And of course，she was able to pay off her credit card debt．She also sold her designer clothes on eBay．In her closet，where the Gucci purse once sat，Karyn keeps all the letters that people have sent her．
It's hard to understand why so many people helped a total stranger pay off her huge credit card bill．Karyn explains，"I was just honest about what happened； I didn't make up some sob story （悲伤的故事） about saving the world．"Her donors think it's funny and original，and view it less as a charity than as an entertainment site．Imitators have appeared all over the Internet，some with extremely selfish requests for things like a BMW or a house．
Actually，Karyn was not the first person to put up a website asking strangers for money．The practice has a name："cyber-begging．"Most sites receive little traffic and even less cash．Karyn also had thousands of enemies and critics．People sent her hate mail and scolded （斥责） her on websites．Karyn says she never let this anger bother her．"They are probably jealous （嫉妒的） they didn't think of it．"She explains．
