The last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at homewith her parents. But through working as a part-time skating instructor and restaurant server, she isn't able to earn enough to live anywhere other than home.
To some degree, multigenerational households have always been a part of American life. However, the number of young adults who have been moving back in with their parents — or never leaving home in the first place — has been growing steadily.
UBS Financial Services released a report that even suggests one reason for the growing number of young adultsstill living at home could be that their family doesn't want them to leave.
The report shows that 74 percent of millennials (千禧一代)get some kind of financial support from their parents after college. It finds that millennials have redefined the ties that connect parents and children. Millennials see their parents as peers,friends and instructors. Nearly three quarters talked with their parents more than once a week during college. In return, their parents happily provide financial support well into adulthood, helping fund everything for them.
Stuart Hoffman, chief economist for the PNC Financial Services Group in theUS, said the number of young adults striking out on their own fell during the Great Recession. Although job growth for millennials since 2014 has improved, that doesn't necessarily mean that millennials are starting to fly the nest. He said, “They may like living at home and being able to save money.
“ There's no doubt it has held back household formation and purchases of things people spend money on related to household formation and perhaps related to child-raising," Hoffman explained. "But they are probably traveling more and eating out more if they don't have a house expense or marriage. I don't know if it represents a change in moral values. But it's much more common for adult children to live in their parents’ homes because it's becoming part of the culture.
1. What can we learn from the UBS Financial Services' report?
A. Millennials are on good terms with their parents.
B. Millennials are financially independent after college.
C. Parents are unwilling to give their young adults allowance.
D. Parents want their kids to stay with them forever.
2. What does Hoffman think of young adults' living at home?
A. It increases the consumption of household products.
B. It may continue despite job growth.
C. It is a sign of shift in moral values.
D. It is new in American culture.
3. What is the author's purpose of writing this passage?
A. To introduce millennials' living habits.
B. To stress the importance of financial independence.
C. To explain why American young adults still live at home.
D. To inform people of a social trend in theUS.

Medha Gupta sometimes felt worried about making the 20-minute walk from the corner where the school bus dropped her off to her home in Herndon -especially during the colder months in winter.
Her mother, Divya Gupta had a suggestion: write an app. Shewas half-kidding,but Medha didn't take the challenge lightly. So she set out to work.

She temporarily has her app-development ambitionson holdbecause she's busy teaching herself artificial intelligence to help deal with improper words on Facebook. Yes,she knows that there are teams of engineers probably doing the same thing. But she figures it can't hurt her own part, too.

Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February,said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects areimportant prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change
and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is ly easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.
8. What is discussed in the passage?
A. Causes of declining insect populations.
B. Consequences of insect population collapses.
C. Light pollution: the key bringer of insect declines.
D. Insect declines: the driver of the collapsed ecosystem.
9. What is the 5th paragraph mainly about?
A. How light travels in space.
B. How light helps insects find food.
C. How the food chain is interrelated.
D. How light pollution affects insects.
10. What does the underlined word"analogues"in Paragraph 6probably mean?
A. Selective things.
B. Similar things.
C. Variations.
D. Limitations.
11. What is the purpose of the last paragraph?
A. To offer solutions.
B. To give examples.
C. To make comparisons.
D. To present arguments.
D
Kenyan mother Beth Mwende heard her sleeping child cry out, but did not worry after the three-year-old quickly quietened down. The next morning, however, she found her daughter, Mercy, nearly unconscious with two bite marks in the neck. “I didn’t know that it was a snake,” Mwende said.
Although snakebites are common in her hometown, antivenom medication is difficult to get. Mwende lives about 160 kilometers east of Nairobi, Kenya’s capital. So she took her daughter to a traditional healer. He placed stones over the bites. Mercy died within hours. She was one of about 700 Kenyans killed by snakebites each year,
notes a report in the scientific publicationToxicon.
The Kenya Snakebite Research and Intervention Center (KSRIC) is working to change that. The KSRIC hopes to have East Africa’s first antivenom medication on the market within five years. It estimates the cost will be about 30 percent of an imported product, which often sells for about US $ 30.
More than 70, 000 people are bitten in East Africa each year. Climate change and deforestation are worsening the problem as snakes get pushed out of natural surroundings into populated areas.
Nearly 100 snakes live at the research center in a forest near Nairobi. Researchers take venom from snakes and study it before injecting small amounts into other animals, such as sheep. The animals then create antibodies that can be made into antivenom.
“Up to now, no one has made any kind of antivenom in Kenya,’’ said Geoffrey Maranga Kepha, a senior snake handler.
Two effective antivenoms are available in Kenya, from India and Mexico, the center says.
The center is teaching communities that using antivenom immediately after receiving a snakebite can save lives, said head researcher George Adinoh.
“After seeing how people died in Kenya from snakebites I decided to devote my life to coming up with a rescue measure that will help or prevent people from dying from snakebites,” snake handler Kepha added.
12. How does the author introduce the topic of the text?
A. By telling a story.
B. By listing figures.
C. By referririg to documents.
D. By making a comparison.
13. Why did Mwende take her daughter to a traditional healer?
A. She couldn’t afford any modern treatment.
B. She lived where antivenom medication is not available.
C. The traditional way is very effective to treat snakebites.
D. She believed a traditional healer could cure her daughter.
14. What is causing more snakebites to happen in East Africa?
A. Lack of antivenom medication.
B. Environmental damage and climate change.
C. People’s low awareness of the danger of snakes.
D. People’s pursuit of traditional cures for snakebites.
15. What do we know about antivenom in Kenya from the text?
A. Itis taken from antibodies of sheep.
B. There is only one effective antivenom available.
C. KSRIC is trying to develop a local antivenom now.
D. People refuse to use antivenom after being bitten by snakes.

Sometimes our classmates talk about that we can do for our school before graduation. We have different kinds of advices. Some think it is a good idea donate some reference books but notebooks to the school library. By doing so, the fellow students will be able to read it if necessary. Others thought it good to plant trees next to teaching buildings to make the school more beautiful.
On my opinion, we can do something meaningfully in honor of our school life. For the example, we can do some voluntary work or send the school some pictures drawing by ourselves, which can remind us of the golden memories.

Overcoming Adversity
On the bus headed to the United States from Mexico, I experienced the saddest and longest ride I ever had. The thoughts of me not seeing my friends and family again were taking over my mind and causing a strong sense of depression. As I headed to a place I didn’t want to call home, minutes felt like hours and the hours felt like days.
“Welcome to the United States,” the driver said at the immigration checkpoint. The Officers repeatedly asked me for my passport, but I didn’t understand a single word coming out of their mouth. After we sorted out all the confusion we were on our way. With 3 hours left, a new thought took over my mind: stupidity. Not being able to understand a new language was the cause of my feeling. This filled me with a burning rage that I had never felt before.
Not understanding the new language I was introduced to was always a problem that I struggled with alone. In school, I felt like the problems were growing rapidly and I was losing control. The transition from being a straight-A student in Mexico to being a straight F student in the United States wasn’t easy and left me wondering if I could ever belong here. I was always known as the weird（怪的）Mexican in the classroom. Making friends was always hard because no one wanted to hang out with the weirdo（怪人）in the class.
I told myself that if I wanted to overcome my problem I had to practice it more. When it came to group assignments, I thought that it was the perfect moment to carry out my plan to hold a conversation with someone else. The moment arrived, I was nervous that it was my time to speak in the group. With a stutter（结巴）, my first words came out of my mouth. “Hey my name is Jesus,” I said with a strong Mexican accent. Everyone in the group
burst out laughing and the cause of their joy was my strong Mexican accent. This made me want to crawl up into a little ball and start crying in front of everyone.
