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.
1.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

3.The drugs in special chicken eggs can ________.
A. treat lung cancer B. help reduce headache
C. change people’s DNA D. treat multiple sclerosis
4.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

Are the lives of city kids the same as those in villages? In lots of ways, they are very different. But what are those differences?
Hu Peng from Wuhan and four of his friends decided to find out. Earlier this month, they went to live for a week in Caidian, a village near Wuhan. Hu and his Junior l classmates went door to door in Caidian and asked kids lots of questions. They want to learn more about village kids' everyday lives, so they asked questions like this: Do your parents teach you how to do the housework? How much money do you usually spend on dinner? What would you do if a thief came into your house? They also asked 150 city kids the same questions.
On April 12, the team gave a report to their class. They told about many differences between children's lives in cities and those of children in villages. The biggest difference is about independence. Hu's team found that 60 percent of city kids can't do much housework, but 90 percent of village kids can care for themselves.
City kids told Hu they care about schoolwork a lot, and they have no time for washing clothes or making their beds. Village kids said they help their parents a lot : cooking, cleaning the houses and feeding pigs. Hu's team also found that village kids have less pocket money. Many have never used computers. They like playing in rivers or on mountains. Some don't even like to make new friends.
Hu and his friends said their trip gave them more self- confidence (自信) because they have done something by themselves. But it also worried them a bit because they found they still have a lot to learn. "When we grow up, our parents can't take care of us," Hu said. "We have to learn to take care of ourselves. " Shen Guanquan, one of Hu's friends said, "When people learn to care for themselves, they learn to do lots of difficult things. "
1.How many city kids went to learn about village kids' everyday lives?
A. Three. B. Four. C. Five. D. Six.
2.Their report showed that most city kids ＿＿.
A. help their parents a lot B. have less pocket money
C. can take care of themselves D. still have a lot to learn
3.The underlined word "it" in the last paragraph means ＿＿.
A. their trip B. their report C. a village kid D. a city kid
4. Hu Peng and his friends finished their report by ＿＿.
A. visiting schools in the village
B. questioning village and city kids from door to door
C. watching village and city kids' everyday lives
D. questioning village and city kids' parents

Cheating can happen in a lot of different ways. When people cheat, it’s not fair to other people, like the kids who studied for the test or who the true winners of a game were.
Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn’t solve the problem of not knowing the material and it won’t help on the next test---unless the person cheats again.
People lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and may be at home, too.
Some kids cheat because they’re busy or lazy and they want to get good grades without spending time studying. Other kids might feel like they can’t pass the test without cheating, even when there seems to be a good reason for cheating, cheating isn’t a good idea.
If you were sick or upset about something the night before the day and couldn’t study, it would be better to talk with the teacher about this. And if you don’t have enough time to study for a test because of swim practice, you need to talk with you parents about how to balance swimming and school.
A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions(解决办法) together. Talking about these problems and working them out will feel better than cheating.
1.The author thinks that when kids cheat in class, ______.
A.it is unfair to other people. B.it does harm to their health.
