Across America, libraries used to reach out to readers by sending bookmobiles into school parking lots, street corners and rural byways (侧道). Now, those rolling reading rooms are becoming fewer.

One town in northern New England just lost its bookmobile. The Cobleigh Public Library in Lyndonville, Vt., had managed to keep its van (有蓬货车) rolling until about a month ago, when it died.

If you want to hear first-hand what it’s like to go through a whole month without a single visit from the bookmobile, just ask the preschoolers at a daycare centre.

“We miss the bookmobile,” one child says. “Yeah, we miss the bookmobile until it comes here,” says another.

Now that the bookmobile has broken down, librarians have to bring books in their own cars for story hour. Daycare provider Anneka Bickford says it’s not as exciting as having a big, brightly painted van roll into the driveway and open its doors so the kids can choose their own books.

“It’s getting the children involved with what a library is, how to check out books and how to return books,” Bickford says. “They would do programs with the children; singing, dancing, themes—so it’s the excitement of the library that we can’t give to the children.”

It’s not the first bookmobile to bite the dust. Over the years, Vermont’s large number has reduced to three or four. Lyndonville’s head librarian, Cindy Karasinski, says replacement costs have risen quickly.

“New bookmobiles are expensive; just one of them costs $90,000,” she says, “so that seems not the way we are going to go.” Sadly, Karasinksi says, money that used to support bookmobiles has nearly dried up.

However, not everyone hopes the Cobleigh bookmobile gets a second chance. Some in town feel the bookmobile has served its purpose and become a financial burden (财政负担).

6 . I did have a really amazing time in Rio! I worked as a volunteer there to promote (提高) the local people’s awareness (意识；认知) of their own health. Therefore, I stayed there for a period of time. During this period of time, I learnt how to take blood pressure and how to give advice in Portuguese to people with high or low blood pressure. I also gave some English lessons at the building or clinic (诊所) I was in when I was not very busy.

When I think of those days in Rio, I would say that really a volunteer should stay at least for four weeks in order to have time to settle in and see progress in their work, especially since volunteering is only four days a week. Also, on the health program, I found that there wasn’t work to do unless you made work. For example, the volunteer I was working with had set up a blood pressure awareness program. So some days we went around the poor areas in the city where only the poorest local people live. I went there to measure people’s blood and give them advice about their life. We felt quite full while other days could be very quiet if we sat in the clinic waiting for people to come to us to get measured. Volunteers should also be aware that things don’t always happen that fast and it can be hard to see progress in only four weeks, so try to stay longer if you can.

Also, people in the poor areas can be very friendly! A local woman that another volunteer and I worked with for a few weeks invited us to her family’s picnic. She and her husband cooked and a lot of her family came — it was really lovely. I found my volunteering in Rio a rich and unforgettable experience.

7 . People are so busy these days that they hardly have time for small household matters like cleaning the house and windows, gardening, and looking after their babies or old ones. It is really difficult for them to manage between their households and professional life. They wish they could have an Angel who could help them out. Do such Angels really exist? Of course, yes! You just need to find them!

Angels don’t need to have wings and a halo (光环). They can be anyone who is ready to help you in need. And in this fast-paced world when everyone is so busy, such people who help you are really no less than angels. Your life would be definitely wonderful if you could find an angel doing cleaning for you. There are definitely various service providers who can easily provide you with such angels. Won’t you just take it if you can get all these services from one single provider?

Task Angels is one of such service providers that provide you with helpful angels who offer services that will not disappoint you at all. Established with the purpose of helping people, this has been playing an important role in domestic cleaning and other services. You may join the team as well if you want to help the people in need and are good at cleaning, gardening, babysitting or even event planning. Task Angels definitely waits for you.

Everyone needs love and care, the more the love and care you share, the more they grow in your family. This is what Task Angels believes. It will help you in the area to make your life easier. Wouldn’t you like to try its service once and encourage it for its good work?

When William Erasmus Darvin was born in December 1839, his father Charles Darwin began to carefully record observations of his firstborn in a notebook. Now housed at Cambridge University Library, it reads more like a research paper.

Today we know a good deal about Darwin s theories. We know far less about how his private life-particularly his family- contributed to his work. But his notebook shows another side of the founding father of evolution: Darwin as a family man.

Darwin’s son William was born a year after the scientist first met London Zoo’s first orangutan(猩猩), Jenny. “The orangutan for Darwin was like a window into the origins of mankind,” says John van Wyhe, director of Darwin Online.

At this time, Darwin was already forming ideas about where humans came from, but he had never met one of our close ape(猿)relatives to test these theories. His meeting with Jenny helped build up his idea that we shared a common ancestor(祖先). with apes. He was already looking for a “real relationship between humans and apes”, says van Wyhe. When he saw Jenny’s facial expressions and noticed her social behaviour, he knew his ideas were right.

What stood out to him was how human-like some of her behaviour was, which he wrote about in a letter to his sister Susan: “The keeper showed her an apple, but would not give it to her, whereupon she threw herself on her back, kicked and cried, just like a mischievous child.”

When his son was born soon after, it meant that he could see first-hand how a human child developed, and consider the relationship between humans and animals. The notebook shows Darwin as a good-humoured though curious father who is “playing with his young baby like he s another ape, says van Wyhe.

His observations about both his family and Jenny the ape went on to influence his 1871 book. The Descen of Man and The Expression of the Emotions in Man and Animals, published in 1872.

10 . Social media use has been linked to mental health, especially in teenage girls. But a new study argues that the situation may be more serious than experts think.

The research involved interviews once a year from 2013 to 2015 with almost 10, 000 children between the ages of 13 and 16 in England. They would report how many times a week they used social media on average. Based on the results,researchers would lean how dependent they were on the social media. Researchers noted that they did not get how much time those children spent on the websites, which is a limitation of the study.

“Our results suggest that social media itself doesn't cause harm, but that frequent use may subvert activities that have a positive influence on mental health such as sleeping and exercising. And then it will increase exposure (接触) of young people to harmful content, particularly the negative experience of cyber - bullying (网络欺凌),” study co - author Russell Viner said in a statement. Researchers found that social media may harm girls' mental health. However, for boys, the influence on their mental health seems to be due to other reasons, so further research is needed.

In 2014 and 2015, researchers asked about the teens' psychological sufferings and their personal happiness. The researchers found that, in both sexes, very frequent social media use was connected with greater psychological sufferings. The effect was especially clear among girls. The more often they checked social media, the greater their psychological sufferings would be.

Bob Patton, a psychologist from the University of Surrey, said the research showed strategies focusing only on reducing social media use as a tool to improve mental health might not help. “Building strategies to increase resilience (适应力) to cyber - bullying and improve the sleep and exercise behaviors may help reduce both physical and psychological harm,” Patton, who was not involved in the research, said in a statement. “If teenagers can change their unhealthy lifestyle and cyber - bullying can be reduced, the positive effects of social media use can be supported,” he added.
