Medicine comes in lots of different packages. Painkillers in a tablet can make your headache go away. Antibiotic cream (抗菌素膏) from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?
A team of scientists from Scotland say “yes”. They’ve engineered special chickens that lay eggs with disease-treating drugs inside.
These eggs come from chickens that have been engineered to produce certain drugs inside their egg whites.
These drugs are made of molecules called proteins(蛋白质). Animals make thousands of proteins — they’re the main element in skin, hair, milk and meat. Since animals can make proteins easily, they’re good candidates (候选者) for making protein drugs.
Researchers have already made cows, sheep and goats produce protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. Those qualities could make chickens a better choice to become living drug factories, says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA — the code that tells cells how to make proteins — so that the birds’ cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis (多发性硬化).
The scientists changed the chickens’ DNA so that the birds made these drugs only in their egg whites. This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs. If you cut your finger, you may use ________ to cure it.
| A．painkillers in a tablet | B．antibiotic cream from a tube |
| C．chicken eggs | D．protein drugs |
Which of the following statements is NOT true?
| A．Scientists from Scotland have succeeded in packing medicine into chicken eggs. |
| B．The drugs are made of molecules called proteins. |
| C．Scientists chose chickens for their experiments because chicken eggs taste delicious. |
| D．The animals are good candidates for making protein drugs. |
The drugs in special chicken eggs can ________.
| A．treat lung cancer | B．help reduce headache |
| C．change people’s DNA | D．treat multiple sclerosis |
We can infer from the passage that ________.
| A．eating eggs is the best choice for the patients now |
| B．scientists changed the chicken’s DNA and put all the drugs in chicken eggs |
| C．we may eat special eggs as drugs when we are sick in the future |
| D．the drugs produce harmful effects on the chicken’s bodies |
The best title for the passage is ________.
| A．Chicken Eggs to Replace Medicine | B．Chicken Eggs as Drug |
| C．Chicken Eggs and Medicine | D．Chicken Eggs and Animal Milk |
How do apology languages work? Have you ever tried to apologize, only to be refused? It may be that you were offering a partial apology in a “language” , that was foreign to your listener．The five languages of apology include:
Apology Language 1: “I am sorry.”
List the hurtful effects of your action．Not “I am sorry if …”, but “I am sorry that…”．You might ask if they want to add any points that you have not recognized.
Apology Language 2:“I was wrong.”
Name your mistake and accept fault．Note that it is easier to say “You are right” than “ I am wrong”, but the latter carries more weight.
Apology Language 3: “ What can I do to make it right?”
How are you now? How shall I make amends(弥补) to you? How can I restore your confidence that I love you— even though I was so hurtful to you?
Apology Language 4: “I’ll try not to do that again.”
Engage in problem-solving．Don’t make excuses for yourself such as, “Well, my day was just so…” Instead, offer what you will change to prevent yourself from putting them in the same bad situation again．
Apology Language 5: “Will you please forgive me?”
Be patient in seeking forgiveness．They may need some time or greater clarification of your input from Apology Languages 1-4.
Finally, your apology may not be accepted, but at least you know that you 
have been faithful in offering a sincere olive branch of peace.The passage mainly talks about___________

A research by the National Center for Health Statistics is seen as an important confirmation of the“Hispanic mortality paradox（西班牙裔死亡率悖论）.”
On average，Hispanics outlive whites by 2.5 years and blacks by 7.7 years. Their life expectancy at birth in 2006 was 80.6 years，compared with 78.1 for whites，72.9 for blacks and 77.7 years for the total population.
The report shows that the Hispanic population has higher life expectancy at birth and at almost every age despite a socioeconomic status lower than that of whites.“Mortality is very correlated with income，education and health care access，”says Elizabeth Arias，author of the report.“You would expect the Hispanic population would have higher mortality，”in line with the black population.
The Hispanic paradox has been documented for more than two decades，but this is the first time the government has had enough data to issue national numbers. Researchers are struggling to explain why Hispanics live longer.
“We don’t know，”says David Hayes-Bautista，director of the Center for the Study of Latino Health and Culture at UCLA’s David Geffen School of Medicine.“We thought it was a problem in the data，but we can pretty much say this is real.”
Potential factors:
·Culture and lifestyle. Support from extended family and lower rates of smoking and drinking.Latino groups in particular have very strong family and social ties.
·Migration. The“healthy migrant effect”argues that healthy people are more likely to emigrate. And when immigrants become ill，they might return home and die there.
Solving the puzzle may help the nation deal with health care issues because Hispanics use health services less—they make fewer doctors visits and spend less time in hospitals，Hayes-Bautista says.“It’s clearly something in the Latino culture，”he says.In 2006，Hispanics’life expectancy is years longer than the average of the total population.
| A．2.5 | B．7.7 | C．2.9 | D．80.6 |
What does the underlined word“outlive”in the second paragraph probably mean？
| A．To live longer than… | B．To live shorter than… |
| C．To die out. | D．To expect to live. |
What is the main idea of paragraph three？
| A．Hispanics were born better than whites. |
| B．Morality is closely related with health care access. |
| C．Whites should have longer life expectancy. |
| D．Even experts can’t explain the phenomenon. |
What is Mr.Hayes-Bautista’s opinion about the paradox？
| A．He supports there is a problem with the data. |
| B．He intends to trust the cultural factor. |
| C．He believes in the“healthy migrant effect”. |
| D．He thinks health care the most important factor. |
Which of the following inferences is true according to the passage？
| A．Black people suffer the lowest social status in America. |
| B．Hispanics might have healthier ways of life. |
| C．Only healthy people can immigrate into America. |
| D．White people don’t have strong family ties. |
NEW YORK—Microsoft on Monday made another effort to challenge Apple’s iPhone and Google’s Android in the exploding smartphone market—launching a wireless operating system，Windows Phone 7.
Consumers will consider it“always delightful and thoroughly mine，”Microsoft CEO Steve Ballmer said at a launch event. Ballmer said last year that Microsoft had“screwed up”with its Windows Mobile operating system.For example，it failed to keep up with touch-screen innovations that make iPhones and Android phones easy to use.
Microsoft fell from third to fourth place in market share this year，behind BlackBerry，iPhone and Android. Only 10.8% of smartphone owners used Microsoft’s system in August，down from 18% last December.
But Windows Phone 7 is“a total departure from anything they’ve done”.Microsoft says it sought to simplify common activities. For example，you can instantly take a picture with a phone’s camera by pushing a button on the device. You don’t have to first awaken it from its sleep mode and launch the camera application. You also can program the phones to automatically upload photos to Facebook or other social network sites in a couple of seconds. Users can easily work with Microsoft Office contact and calendar information as well as documents created in Microsoft’s Word，Excel and PowerPoint.
The phones will not show videos built on Adobe’s Flash platform，widely used by services including YouTube and Hulu.
AT&T will offer the first Windows Phone 7 smartphone，the Samsung Focus，on Nov.8.Soon after，it will have the LG Quantum and HTC Surround. Each will cost S| 199.99 with a two-year service contract. T-Mobile will have two Windows Phone 7 models out for the holiday shopping season：the HTC HD7 and Dell Venue Pro. It did not say how much they’ll cost.What is the main idea of paragraph 4？
| A．Why Microsoft fell behind others. |
| B．How to use Windows Phone7. |
| C．Advantages of Windows phone7. |
| D．Speed of Windows phone7. |
What does the underlined phrase“screwed up”in the 2nd paragraph probably mean？
| A．To make a bad mistake. | B．To make big progress. |
| C．To achieve main goals. | D．To keep up with others. |
Which of the following phones will NOT use Windows Phone 7 operating system？
| A．Quantum. | B．Surround. | C．Android. | D．Focus. |
Why did Microsoft see a drop in market share last year？
| A．Because its operating system didn’t catch up with changes. |
| B．Because its phones can’t show videos from YouTube. |
| C．Because it was inconvenient to take photos using its phones. |
| D．Because its system was based only on Microsoft soft wares. |
Which of the following can be the best title of the passage？
| A．Smartphone Market Welcomes New Giant |
| B．Microsoft to Fight Back on Smartphone |
| C．Mobile Phones Getting Smarter and Easier |
| D．Microsoft Proved a Failure in Smartphone |
Surveys of American teenagers find that about half of them do not get enough sleep on school nights. They get an average of 60 to 90 minutes less than experts say they need.
Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups. Yet many schools start classes as early as seven in the morning.
As a result，many students go to class feeling like Danny，16 years old. He plays two sports，lacrosse and football. He is an active teen—except in the morning. DANNY：“Getting up in the morning is pretty terrible. I’m just very out of it and tired. And through first and second period I can hardly stay awake.”
Michael Breus，a clinical psychologist with a specialty in sleep disorders says：“These aren’t a bunch of lazy kids—although，you know，teenagers can of course be lazy. These are children whose biological rhythms，more times than not，are off.”Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night. He says sleepy teens can experience a form of depression that could have big effects on their general well-being. It can affect not just their ability in the classroom but also on the sports field and on the road because any tired driver is dangerous，especially a teenager with a lack of experience.
So what can schools do about sleepy students？The psychologist says one thing they can do is start classes later in the morning.
Eric Peterson，head of St.George’s School in the northeastern state of Rhode Island，says，“In the end，schools ought to do what’s the right thing for their students，first and foremost.”And he wanted to see if a 30-minute delay would make a difference. It did.According to the passage，which of the following is the chief cause of sleepy teenagers？
| A．Persona haibits. | B．Early school hours. |
| C．Sports activities. | D．Too much home work. |
According to Michael Breus，.
| A．Teenagers are too lazy to get up early for school. |
| B．Teenagers should change their biological rhythms. |
| C．Lacking sleep can cause serious problems. |
| D．Sleepy teenagers shouldn’t drive to school. |
What is Eric Peterson’s opinion on the issue？
| A．Schools should try their best to help students. |
| B．Students should adjust to their school’s schedule. |
| C．Changing school schedule is their last choice. |
| D．Something has to change at the end of a school day. |
What does the underlined word“It”in the last sentence might refer to？
| A．St.George School. | B．Rhode Island State. |
| C．Students in St.George School. | D．30-minute delay of school day. |
What can you infer might follow the passage immediately？
| A．Some positive changes in St.George’s school. |
| B．Some complaints from teachers and parents. |
| C．Some tips on how to help students foremost. |
| D．Some unexpected outcome of the delay. |
“It was cool，because I got a chance to be in a studio and see how a record is made，”says 14-year-old Javon Martin，who joined the music clubhouse 3 years ago.“It has impacted my life in a big way. People are actually starting to see me as an artist.”Ten-year-old Akheylah Hunter didn’t play an instrument when she became a club member last year. Now，she plays piano and sings with the band. What she likes best，she says，is performing.“We performed in different places，”she says.“We go on trips and it is fun.”
Since the Music Clubhouse opened three years ago，it’s served almost 500 kids.Aggeler says performing in front of different audiences helps the young musicians build self-esteem.Coming to the club to prepare for those performances helps them learn how to deal with their personal problems and concerns.
“I can see what it does for them and it just develops confidence，”he explains.“It’s also an escape from the big problems we have in the neighborhood. So whether they feel embarrassed about a zit on their face，or they feel embarrassed because they’re not as tall as somebody，they can rap about it and let it out a little bit.”
To expand the club and help more kids learn music，Aggeler sought the support of the community. The Berklee College of Music and local music stores have provided free equipment. The club has also gotten support from the Music and Youth Initiative，a nonprofit that develops after school music education programs in underserved communities in Massachusetts. All these have made it possible to provide kids who may not have the means to get private music lessons the opportunity to still learn music and get all the benefits that music education brings.”Why does the writer mention the two children in the first paragraph？
| A．To tell readers that all children like music. |
| B．To provide examples of how children like the club. |
| C．To convince readers that music can solve many problems. |
| D．To show readers how to discover children’s potentials. |
Which of the following was NOT mentioned as a benefit of joining the club？
| A．Helping the youngsters to build self-confidence. |
| B．Helping its members escape from problems. |
| C．Learning to deal with personal problems. |
| D．Learning to get help from nonprofit groups. |
What is Mr.Aggeler’s possible post？
| A．An organizer of the club. | B．A conductor of the band. |
| C．An expert in child problems. | D．A parent of one of the children. |
What does the writer intend the passage to be？
| A．An advertisement for a club. |
| B．A promotion of some non-profit groups. |
| C．An introduction of a music club for children. |
| D．A try to call for attention on children’s needs. |
Which of the following might NOT be included in activities of the club？
| A．Putting on performances. | B．Making records. |
| C．Traveling to different places. | D．Giving private music lessons. |
