“What kind of rubbish are you?”This question might normally cause anger，but in Shanghai it bas brought about weary complaints over the past few months. On July 1st，the city introduced strict rubbish-sorting regulations that are expected to be used as a model for our country. Citizens must divide their waste into four separate categories and put it into specific public bins. They must do so at scheduled times, when monitors are present to ensure that rules are obeyed and to examine the nature of one's rubbish.
Violators could be hit with fines of up to 200 yuan ($29). For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain hank loans or even buy train tickets.
Shanghai authorities are responding to obvious environmental problem. It produces 9 million tons of garbage a year. But like other cities in china, it lacks a recycling system. Instead, it has relied on rubbish pickers to pick out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up. China produces 80 billion pairs of one-off chopsticks a year.
Many citizens appear to support the idea of recycling in general but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous（有害的），the distinctions among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and toss（投掷）it by hand, Most annoying are the short periods for throwing trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.
1.What's the purpose of Paragraph l?
A.To complain about rubbish dividing.
B.To explain the four categories of the waste.

3.What makes the citizens upset most about the rules?
A.Complex distinction among the four categories of rubbish.
B.Short scheduled time for tossing rubbish.
C.Being observed by monitors when throwing the garbage.
D.Being fined when blamed due to improper behavior.
4.What can be the best title for the text?
A.A Restart of Waste-sorting B.A New Age of Garbage Classification
C.Learning to Classify Rubbish D.Rubbish-sorting Benefits the World
Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
1.What does "these two killers" in the second paragraph refer to?
A.Gene technology and another treatment of the two diseases.
B.The two murderers who killed the cloned baby
C.The two diseases of cancer and heart disease
D.Hereditary diseases and cancer
2.What’s the main idea of the third paragraph?
A.How gene technology can be applied in the field of treating hereditary diseases.
B.Gene technology can be used to clone human babies.
C.Gene technology can help people to give birth of a baby.
D.Gene technology can help the English imperial family out
3.In what way gene technology can help to treat hereditary diseases?
A.Using gene technology, people with hereditary diseases can have more living days.
B.Using gene technology, scientist finds the wrong gene and corrects it.
C.Using gene technology, human babies can be cloned.
D.Doctors can cure cancer and heart disease with the help of gene technology.
4.What is the main purpose of writing this passage?
A.Expressing the writer’s idea that gene technology will benefit people
B.Telling people the advantages of gene technology
C.Telling the readers that gene technology will not benefit people
D.Explaining that gene technology will also do harm to the humanity
Your teenage best friend could be good for your long-term mental health，according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found．
“Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood，”the authors, led by Rachel K, Narr，a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.
A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. “My hunch（预感）was that close friendships compared to broader friendship groups and popularity may not function the same way,” Narr told Quartz. "Being successful in one is not the same as being successful in the other."
Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.
And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.
1.What is the benefit of having a close teenage friendship?
A.Excellent performance in high school. B.A larger group of friends.
C.Mental health by early adulthood. D.A large social network in the future.
2.What can we learn about the past research?
A.It attached great significance to adolescent friendships.
B.It was totally different from the new research.
C.It helped improve teenagers' mental health.
D.It compared broader friendship groups with popularity.
3.What did the researchers think might lead to the mental health benefits?
A.Not continuing to have a close relationship. B.Having a best friend in high school.
C.Understanding the world of social media. D.Knowing how to build a close friendship
4.What did the researcher Joseph suggest?
A.Learning to use social media.
B.Broadening your social circle.
C.Improving the skills of making friends.
D.Concentrating on high-quality relationship.
