Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly.

    The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.

    In any case, parents should make clear what, if anything, the child is expected to pay for with the money.

    At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget demands choices between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics.

    Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save and maybe even invest (投资) it.

    Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A savings account is an excellent way to learn about the power of compound interest (利息). That may not seem like a lot. But over time it adds up.

    I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. There was a time when I thought I would never have that sort of career.

    I wasn't an excellent student because I didn't do much schoolwork. In my final term I started thinking what I might do and found I didn't have much to offer. I just accepted that I wasn't the type to have a career.

    I then found myself a job, looking after two little girls. It wasn't too bad at first. But the problems began when I agreed to live in, so that I would be there if my boss had to go out for business in the evening. We agreed that if I had to work extra hours one week, she'd give me time off the next. But unfortunately, it didn't often work out. I was getting extremely tired and fed up, because I had too many late nights and early mornings with the children.

    One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification if I wanted to work with children. I didn't think I would be accepted because I didn't take many exams in school. She persuaded me to phone the local college and they were really helpful. My experience counted for a lot and I got on a part-time course. I had to leave my job with the family, and got work helping out at a kindergarten.

    Now I've got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that you could have a career, even if you aren't top of the class at school.

Climbing Without Ropes

    The popular image of the mountain climber is of a person carefully climbing a steep cliff with a network of safety ropes, but it is not the only kind. Many climbers now enjoy bouldering. It's more accessible and better for the environment.

    Here is an example of a climber addressing a bouldering problem.

    Figure 1: The climber has two routes she could take, one to the left and one to the right. The left one appears easier because it has a jug within easy reach, but look what happens if she chooses that direction. She gets stuck on the rock and has to go back down. Sometimes that is even difficult than going up.

    Figure 2: The climber takes the one to the right this time. using a foothold and placing her right hand in a crimp, she is able to life herself up and locate other handholds. After only a few moves, she is able to throw her leg over the top of the boulder and pull herself up.

    Welcome to one of the largest collections of footwear(鞋类)in the world that will make you green with envy. Here at the Footwear Museum you can see exhibits from all over the world. You can find out about shoes worn by everyone from the Ancient Egyptians to pop stars.

    Room 1

    The celebrity(名人)footwear section is probably the most popular in the entire museum. Started in the 1950s there is a wide variety of shoes and boots belonging to everyone from queens and presidents to pop stars and actors! Most visitors find the celebrities" choice of footwear extremely interesting.

    Room 2

    Most of our visitors are amazed-and shocked-by the collection of “special purpose” shoes on exhibition here at the Museum of Footwear. For example, there are Chinese shoes made of silk that were worn by women to tie their feet firmly to prevent them from growing too much！

    Room 3

    As well as shoes and boots, the museum also exhibits shoe­shaped objects. The variety is unbelievable. For example, there is a metal lamp that resembles(类似于) a pair of shoes, and Greek wine bottles that look like legs！

    The Footwear Library

    People come from all over the world to study in our excellent footwear library. Designers and researchers come here to look up information on anything and everything related to the subject of footwear.

    On Sept. 19 the Westchase Elementary PTA（Parent-Teacher Association）will hold its Wizard Walk. The Wizard Walk is a locally organized, healthy alternative to traditional product sales that will raise money to support all PTA programs and events for the year. Remaining money will be applied to an on-going capital campaign to build a new playground.

    The Wizard Walk will take place on Wednesday, Sept. 28, from 8 a. m. to noon at the Westchase Recreation Center Field.  Volunteers will be needed throughout the event.  Look for more Wizard Walk information and volunteer sign-up links in your student's folder, or contact（联系）Laura Kohler at president＠ westchasepta. org.

    The PTA is also holding a year-long Spirit Stick fundraiser（资金筹集活动）. Spirit Sticks are small and students can display them on a key ring on their backpacks, which represent a variety of interests and accomplishments. There will be many ways to earn a Spirit Stick （good grades, great behavior, exceptional attendance, etc.）and opportunities to purchase the limited edition sticks for just $1 every Friday in the courtyard. For more information, contact Nikki Pivnichny at fundraising@ westchasepta. org.

    In addition to new fundraising programs, the PTA is partnering with our Guidance Counselor, Mrs. Kiersten Rivenburg, on a new campaign called Kindness Counts. Look for new recognitions and rewards as we continue to promote kindness from our children, staff and parents throughout the year. For more information, contact Laura Smith at kindnesscounts@ westchasepta. org.

    Now in its eighth year, the After-School Enrichment Program（ASE）is bringing back some favorite programs and offering some new ones. Students will have the opportunity to explore and develop a variety of new interests. Class schedules will be available soon. Registration starts on Sept. 7. Fall session begins Sept. 21 -22. For more information, contact Jennifer Newman at ase@ westchasepta. org.

    The largest genetic study of mosquitoes has found their ability to resist insecticides(杀虫剂) is evolving rapidly and spreading across Africa, putting millions of people at higher risk of contracting malaria(疟疾).

British scientists who led the work said mosquitoes' growing resistance to control tools such as insecticide-treated bed nets and insecticide spraying, which have helped cut malaria cases since 2000, now threatens "to disturb malaria control" in Africa.

    "Our study highlights the severe challenges facing public efforts to control mosquitoes and to manage and limit insecticide resistance," said Martin Donnelly of the Liverpool School of Tropical Medicine, who worked on the study with a team from Britain's Wellcome Trust Sanger Institute.

    Latest World Health Organization (WHO) data show that 216 million people were infected last year with the malaria parasite(寄生虫), which is transmitted by blood-sucking Anopheles mosquitoes. The disease killed 445,000 people in 2016, and the majority of them were children in sub-Saharan Africa.

    To understand how mosquitoes are evolving, the researchers sequenced the DNA of 765 wild Anopheles mosquitoes taken from 15 locations across eight African countries. Their work, published in the journal Nature on Wednesday, created the largest data resource on natural genetic variation for any species of insect.

    Analyzing the data, the scientists found that the Anopheles gamblae mosquitoes(冈比亚疟蚊)were extremely genetically diverse compared with most other animal species. This high genetic diversity enables rapid evolution, they said, and helps to explain how mosquitoes develop insecticide resistance so quickly.

    The data also showed the rapid evolution of insecticide resistance appeared to be due to many previously unknown genetic variants(变体)within certain genes. The scientists said these genetic variants for insecticide resistance were not only emerging independently in different parts of Africa, but were also being spread across the continent by mosquito migration.

    Michael Chew, an expert at Britain's Wellcome Trust global health charity which helped fund the research, said the finds underlined the importance of pushing scientific research ahead to control malaria.

Global efforts to control malaria through effective vaccine, insecticides and the best drug combinations require urgent, united action by scientists, drug companies, governments and the WHO.
