1 . If you were to throw, say, a banana skin out of your car while driving along the motorway, that would be a completely harmless action, due to the fact that it’s part of a fruit—right? Actually, no. A banana skin can take up to two years to be naturally processed, and a third of drivers confess they litter while driving, that’s a lot of thrown banana skin. An orange skin and a cigarette butt (烟蒂) have similar biodegrading (生物降解) time to that of a banana skin, but tin cans last up to 100 years; and plastic bottles last forever, as do glass bottles.
Despite the fact that longer-lasting materials will serve to damage the environment and its animals for longer, we can’t measure the danger of a certain type of rubbish by its lifetime. For example, despite having a fairly short length of biodegrading time, more than 120 tons of cigarette-related litter is thrown in the UK every day.
It’s not a cheap habit either: to keep our streets clean annually costs UK taxpayers £500 million, and when you include our green spaces, that goes up to £1 billion. So, it’s not surprising that if caught throwing rubbish, you could face a £20,000 fine or even prison time and, if you threw something dangerous, the court could give you five years to serve. Regardless of how serious these punishments might seem, however, among the reported cases only 2,000 were found guilty out of 825,000, so we still have some way to go in making sure people obey the rules.

2 . A sleepover (过夜) program, which is designed to make kids believe that their favorite toys enjoy reading, can help encourage children to pick up more books, a new study suggests.
Toys sleepover programs are designed to get children interested in books. Children take their toys to a library for the night. At this point, workers and volunteers take photos of the toys which explore the library and read books. The next day, the children collect their toys and the photos of what the toys did during the night. They are given the books their toys chose to read.
It was found that before the sleepover the children did not spend time looking at the books in their play area at preschool. Immediately after the sleepover, the number of children who read to the toys was higher than the number who did not, but after three days the effect decreased gradually.
The researchers also tested a method for sustaining the effect. They reminded the children of the sleepover a month later, by hiding the toys and showing them the photos again the next day. This simple method brought an increase in the number of children reading to their toys.
The study proves for the first time that children who take part in sleepover programs read picture books to their toys more. “We wanted to know if there really was an effect, and if so, how long it lasts. Surprisingly, not only did the children show interest in the books, but they also began to read to their toys. This means that a new behavior pattern appeared that the children hadn’t had before. We did not expect anything like this,” said one of the researchers.
Reading is important for the development of children’s language skills and imagination. When parents read to their children, it is a passive way of reading for the child. However, when children read to their toys, it is a more active, self-directed way of reading, helping them develop into more active readers, researchers said.

3 . Saving Money
Where you save your money often depends on what you are saving for. If you are saving to buy a dictionary or to go to a concert, then you probably keep your money somewhere in your room.
If you are saving for a big purchase like a mountain bike or a school trip, where would you save your money?
One place to save money is the bank. Putting your money in a savings account will help your money earn more money. If you put your money in a piggy bank (猪形储蓄罐子), one year later you'll still have the same amount of money you put in. If you put your money in a savings account, one year later, you'll have more money than you put in. Why?
When you keep your money in a bank, your money earns interest. Interest is the amount of money a bank pays you to use your money. The bank uses your money (and the money of other people, too) to loan money to people and businesses.
The bank will send you a statement several times a year. A bank statement tells you how much money there is in your account. It also tells you how much interest you have earned. If you leave your money in the bank, you can watch it grow!
Another way you can save money is to buy a certificate of deposit or CD. If you have some money that you don't need to use for a long time, this is a good way to make your money grow.
You can buy a CD at a bank. You agree not to use the money for a certain period of time. That period might be from six months to five years. You can't touch your money during that time. If you do, you must pay a penalty, or fee.
Since the bank is using your money for that time period, it will pay you interest. You will earn more interest with a CD than in a savings account. Can you guess why? It's because you promise to leave your money in the bank for a certain period of time. Banks pay different rates of interest. So, you may want to compare rates in newspaper ads before buying a CD.
1. Which way will help your money earn more money?| A．Putting your money in your room. | B．Putting your money in a piggy bank. |
| C．Putting your money in your pocket. | D．Putting your money in a savings account. |
| A．a bank lends to people | B．a bank loans to businesses |
| C．a bank pays you | D．a bank uses |
| A．the amount of money you have in the bank |
| B．the current rates of interest |
| C．the current rates of exchange |
| D．the best way to save your money |

4 . “Serena, don’t forget your promise to me that you will mow (割) Mrs Matin’s yard this weekend,” said Dad, “Don’t let me down.” Serena was the oldest child in the family, and one of her chores was to mow their yard. Mrs Martin, their elderly neighbor, was unable to take care of her yard, so Serena’s dad had volunteered Serena for this job. Since Mrs Martin’s yard was not very big, Serena knew the job would go quickly.
However, she still resented her dad’s promise.
“Why didn’t you ask me first?” Serena had complained.
“Did you ask me first when you volunteered me to be in the school festival last fall?” asked Serena’s father.
“Well, no, I didn’t ask you first, but you would have done those things anyway. You’re always willing to help.”
“I try when I can,” Dad answered.
“Serena, we have known Mrs Martin for a very long time. She has often helped our family. Now we can do something for her. Besides, the feeling you get from helping someone makes you wonder who is really helping whom.”
“I don’t know, Dad,” said Serena. “The only feeling I get from mowing our yard is tired.”
“Just you wait and see,” said Dad.
After breakfast, Serena made her way to Mrs Martin’s yard. She was good at her job and soon had Mrs Martin’s yard looking tidy. Mrs Martin came outside with a big glass of orange juice and offered it to her. Serena stopped her work and gratefully enjoyed the drink, while Mrs.Martin talked to her about all of the flowers in her yard. Seeing the joy in Mrs Martin’s eyes, Serena began to understand how much the yard meant to Mrs. Martin.
After finishing her drink, Serena returned to work with a new attitude. A warm feeling began to spread through her body. Her dad was right. It was hard to tell who was helping whom!
1. The underlined word “resented” (Paragraph 2) means___________.| A．understood | B．welcomed |
| C．broke | D．disliked |
| A．Through Dad’s words. | B．Through Serena’s actions. |
| C．Through Mrs Martin’s behaviour. | D．Through the author’s statement. |
| A．Annoyed. | B．Surprised. |
| C．Guilty. | D．Pleased. |
| A．Serena likes the job of mowing her family’s yard. |
| B．Mrs. Martin and Serena did the work together. |
| C．Mrs Martin shared her love for the yard with Serena. |

5 . When homework and tests keep you up late at night, you may plan to make up for your lost sleep during the weekends. But is it useful?
A study published in the journal Current Biology shows that the habit of sleeping in on weekends doesn’t fix the damage that has been done by a lack of sleep during the week. Even worse, it may damage your health.
In the study, which was conducted over 10 days, 36 healthy young men and women with different sleep requirements were divided into three groups. The first group were asked to sleep nine hours a night and the second group five hours a night. The members of the third group slept for five hours on weekdays but rested as long as they wanted on the weekend.
The researchers found that people who lacked sleep ate more snacks and gained weight quickly. However, this wasn’t the case for the first group.
That could be partially due to the shifting of the biological clock and changes to certain body hormones, especially hunger hormones. In order to catch up on their sleep during weekends, people in the third group would eat later as a habit. So their biological clocks shifted, which also changed the production of hunger hormones.
“The hormone leptin(瘦素) decreases appetite(胃口), while the hormone ghrelin(饿素) increases appetite,” explained US researcher Vsevolod Polotsky. “Sleep shortage causes leptin to drop and ghrelin to rise, so you’re hungry and eat more.”
And even if they tried to sleep for as long as they wanted to during weekends, according to researchers, it was still not enough because they found it difficult to fall asleep.
Moreover, short and insufficient sleep schedules will lead to an inability to change blood sugar and increase the risk of metabolic(新陈代谢) disease in the long term.
1. Which of the following is true about the study?| A．Participants were divided into two groups. |
| B．Researchers studied 36 children and adults. |
| C．It lasted for more than two weeks. |
| D．Each group follow different sleep requirements. |

| B．There is less leptin in their bodies. |
| C．They have a lower blood sugar. |
| D．Their bodies produce less hormones. |
| A．Appetite Affects our Sleep Quality |
| B．Sleeping in Causes Weight Loss |
| C．Catching up on Sleep Harms Our Body |
| D．Men and Women Sleep Differently |
6 . How often do you exercise? A new study finds that most kids aged 12 to 15 aren't getting enough physical activity. The results are based on about 800 kids. As part of the study, the young teens tracked and reported on their own activity levels, and took physical exams.
The US fitness guidelines recommend an hour or more of physical activity every day. According to the study, only 1in 4 kids in the US get enough physical activity.
“It's certainly very worrying to see that our kids are engaging in such a limited amount of physical activity each day,” said Dr. Stephen Pont. He is an expert on children's health.
Few kids in the survey met the guidelines for physical activity that raises the heart rate and makes them breathe harder. Overall, about 25% said they got an hour of that kind of violent exercise every day. Kids also reported on which activities they did most often outside of the school gym class--basketball for boys and running for girls.
The study found that obese（肥胖的） teens were less active than normal-weight girls and boys. Overweight girls were slightly less active than normal-weight girls, but levels were similar among overweight and normal-weight boys. The study also said that the overall obesity rate for children aged 2 to 19 is 17%, or about 12.5 million kids.
“There's always room for improvement,” said health expert Tala Fakhouri, who was the lead author of the study. She also said the results provide useful information to help with fitness campaigns such as Lets Move, which was launched by Michelle Obama in 2010. To inspire kids to eat right and get in shape, Michelle visited schools and held exercise events. She also called on schools to offer regular gym classes.
The study also suggests kids who get physical education at school may get better grades.

7 . A year ago, I decided to create a more environmentally friendly kitchen, focusing on reducing the single-use products such as plastic bags and paper towels. I’m not going to sugarcoat my experience. It takes com mitment and a willingness to change long-held habits. In creating my kitchen, I tried a lot of different alternative products and some plain old com mon sense； the result, however, has been worth the effort. I’m recycling more and relying less on single-use products and I’m saving money too.
I’m not kidding when I say that I used to really love plastic storage bags, so this was, perhaps, the biggest challenge for me. Switching to reusable storage bags is a financial investment, but the cos is reasonable considering that I previously spent at least $ 100 annually on single-use plastic bags and wrap. I willcheck online periodically for recycling updates, where a zero-waste box for kitchen items is offered, from party supplies to mixed-materialfood containers.
I’m a clean freak (怪人) and used to go through an amount of paper towels on a daily basis, butit’s easy enough to take old T-shirts ortowels and cutthem up to use to wipe down surfaces. I’m also a fan of bamboo paper towels, which have the look and feel of traditional paper towels, yet are made from a highly renewable source and also break down in just 45 days. Better yet, they can be reused up to 100 times. As for kitchen sponges (海绵擦), I keep an eye out for those made with natural and recyclable materials.
When purchasing household items online from companies like Amazon or Jet, I will ask to have them shipped in as few boxes as possible or as small a box as possible if a single item is to be sent. I’ll let the company know that they should pay more attention to how It is packaging items for delivery.

8 . By now it's almost common knowledge that spending time in nature is good for you. Areas with more trees tend to be less polluted, so spending time there allows you to breathe easier. Spending time outdoors has been linked with reduced blood pressure and stress and seems to motivate people to exercise more.
“So it'll come as surprise that there's research showing that spending time in nature is good. There are dozens of papers showing that,” University of Exeter Medical School researcher Mathew P.White said.“We get this idea-patients are coning to us and they are asking, ‘Doctor, how long should I spend? ’And the doctor is saying,‘I don't really know.’”
So White and his team decided to find out by using data collected from nearly 20,000 people in England through the Monitor of Engagement with the Natural Environment Survey. And their answer? Two hours a week. People who spent at least that much time in nature either all at once or totaled over several shorter visits were more likely to report good health and psychological well-being than those with no nature exposure.
Remarkably, the two-hour standard applied to men and women, to older and younger folks, to people from different ethnic backgrounds, occupational groups, socioeconomic levels, and so on. Even people with long-term illnesses or disabilities benefited from time spent in nature- as long as it was at least 120 minutes per week.
While the findings are based on a vast number of people, White cautions that it's rally just a correlation. Nobody knows why of how nature has this benefit, or even if the findings will stand up to more strict investigation.
“I want to be rally clear about this. This is in very early stages.We're not saying everybody has to do 120. This is really to start the conversation, saying, what would athresholdlook like? What research do we need to take this to the next step before doctors can have the true confidence to work with their patients? But it's certainly a starting point.”

9 . They're life jacket orange, they’re robots and they're capable of sailing the high seas without human intervention.
On Tuesday the National Oceanic and Atmospheric Administration (NOAA) launched a pair of Saildrones(海洋无人机) in Pacific Northwest waters for the first time. Their summer long sailing journey will stretch from Vancouver Island to California. The Saildrone operators will collect data to help set future fishing seasons. The government wants to see whether seagoing. robots can extend fishery surveys now performed by expensive manned ships.
Nora Cohen from NOAA said,“The 23 foot tong seagoing robots can follow a remotely programmed course for up to a year at a time. And they don't require any fuel. We use wind and solar power to drive the sensors.”He added,“It means that we're able to go to places where we don't really want to send people, and go into weather that we really don't want anyone ever to be in, and be able to send back measurements.”
The primary mission is to investigate the species and number of fish in existence and the places where they are. Larry Hufnagle, scientist of NOAA Fisheries in Seattle, said a traditional big NOAA research ship-based survey costs around $25，000 per day. By comparison, one Saildrone runs $2,500 per day.
“It could be a significant saving,”Hufnagle said. “But like anything else, there is a tradeoff in what you get and what you don't get. On the manned ship, we have limited time. It takes a lot of people. We spend a fair amount of money. But there is one thing the Saildrone can't do that humans can: cast a net to catch and positively identify the fish detected below. The Saildrones are going to give us additional data, not replacement data.”
Nora Cohen said Sail Drone, a venture capital-backed company based in Alameda, California, expects to launch a total of 11 of its seagoing robots to survey different water bodies for NOAA this year. The Bering and Arctic seas, coastal California and Gulf of Mexico will be the locations of additional missions.

10 . Young children often “read” picture books. They’re attracted by the colorful scenery and the realistic characters that contribute to fascinating plots.
Unfortunately, some children can’t use these resources, even if they do know how to read. Take three-year old Elodie Bateson, for example. Elodie was born with under-developed eyes and has retinal detachments（视网膜脱落），making her visually impaired.
It is because of people like Elodie that Tom Yeh, head of the Tactile Picture Books Project, has started printing 3D books, so they can feel the illustrations in picture books.
The first book Tom Yeh printed was Goodnight Moon, a popular children’s book about a rabbit going to sleep and wishing good night to his surroundings. In the 3D version of this book， children can feel each thing that the rabbit says good night to, whether it is a cow jumping over the moon, a balloon, or a dollhouse.
Generally, when children grow older, they read by using Braille, a language that was invented by Louis Braille in 1824. It uses different patterns of raised dots representing different letters. Readers can then feel the dots and mentally translate the patterns they feel into words. The only problem is that many blind children do not start learning Braille until they are about six years old.
Another reason why 3D printed books are such a valuable resource is that children don’t have to know how to read to understand them. However, without these, visually impaired kids are losing six developmental years vital to their growth since they can ’t take advantage of picture books.
When 3D picture books are printed, plastic is layered（分层放置）repeatedly over a single shape: the shape of the illustration. These raised pictures created through layered plastic serve as substitutes for the Braille letters that little children have no knowledge of.
