    A new study, a project of the researchers from the University of Pittsburgh in Pennsylvania, finds the fitness tracker probably does not help with weight loss.

    The devices are designed to record your physical activity. They are usually worn around the wrist, where they measure a person's heart rate. The research team looked at two groups of individuals. The first wore a fitness tracker and took part in health counseling (咨询) with experts to consider the best weight-loss plan. The researchers compared this group with people who only got health counseling.

    The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic, the lead researcher, questioned the use of electronic devices for weight control in place of "effective behavioral counseling for physical activity and diet."

    The study involved 470 subjects aged between 18 and 35. Some of them were overweight, while others were considered obese (肥胖的). Over three fourths of the subjects were women. All the subjects were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly counseling, while members of the other group were given a fitness tracker. Eighteen months later, both groups "showed significant improvements in fitness, physical activity, and diet," with no major difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.

    Jakicic said, "the study's findings are important because effective long-term treatments are needed to address America's obesity." More information is needed, he added, to learn how to best use these devices to change "physical activity and diet behaviors" in adults who want to lose weight.

(1)、All the subjects in the study were asked to ________.
A、start on a high-calorie diet B、wear a fitness tracker C、increase physical activities D、record their heart rates
(2)、Why does Jakicic think the findings are important?
A、Wearing fitness trackers hardly helps people lose weight. B、Physical activity and diet have no effect on weight loss. C、Handling obesity requires effective long-term treatments. D、There are great differences in fitness between both groups.
(3)、What can we infer about the study mentioned in the text?
A、The study went on for about two years. B、More than 120 men took part in the study. C、Health counseling helps lose almost 6 kilograms. D、Wearing a fitness tracker is useful for keeping slim.
(4)、The purpose of the text is to ________.
A、describe how the researchers were conducting the study B、indicate regular counseling for weight control is necessary C、convince readers to wear fitness trackers for weight control D、warn women are more likely to suffer from weight problems

    Finding time to read is an important part of developing reading and writing skills for all kids. And there are many easy and convenient ways to make reading a part of each day — even when it's tough to find time to sit down with a book.

    Car trips, waits in checkout lines and the doctor's office are all opportunities for reading. Keep books or magazines in your car, or backpack to pull out whenever you're going to be in one place for a while. Even if you can't finish a book, read a few pages or discuss some of the pictures.

    Encourage kids to bring favorite books and magazines along wherever you go. While it's attractive to provide electronic games and readers, be sure to alternate electronic media with plenty of opportunities to read traditional print books.

    Reading opportunities are everywhere you go. While riding in the car, for example, encourage kids to spot words and letters (on billboards, store signs, etc.), turning it into a game (“Who'll be the first to find a letter B?”).

    Even daily tasks like cooking can provide reading moments. Kids can assist you as you cook by telling you how much flour to measure. Give your child a catalogue to read while you sort through the mail. Ask relatives to send your child letters, e-mail, or text messages, and read them together. Help your child create letters or messages to send back to the relatives. These types of activities help kids see the purpose of reading and of print.

    Even when you're trying to get things done, you can encourage reading. While cleaning, for instance, you might ask your child to read a favorite book to you while you work.

    Make sure kids get some time to spend quietly with books, even if it means cutting back on other activities, like watching TV or playing video games.

    Most important, be a reader yourself. Kids who see their parents reading are likely to imitate them and become readers, too!

    Japan has made a lot of noise in recent years about removing the traditional view that women should stay at home while men go out to work. So it was shocking when, on August 7th, Tokyo Medical University (TMU), a distinguished medical school, admitted marking down the test scores of female applicants to keep the ratio of women in each class below 30%.

    Their defence was that women are more likely to drop out to marry and have children. To judge female applicants to medical school purely on their academic performance would leave Japan with a shortage of doctors, they said. The admission has caused outrage.

    "Doctoring has long been a male field. But it is not the only one. Discrimination is common in banks and trading firms, where stamina (耐力) and loyalty, qualities somehow associated with men, are prized," says Mari Miura, a political scientist at Sophia University. All this embarrasses a government that has promised to make women "shine". The policy seems based on the need for more workers rather than on genuine concern for women.

    Shinzo Abe, the prime minister, says he wants to bring millions more women into the workforce to make up for a labour shortfall caused by its ageing and declining population. In the field of politics, the record under Mr. Abe's premiership (首相任期) is disappointing. Just two members of his 20-strong cabinet are women, including Seiko Noda, in charge of women's rights. Ms. Noda, who makes little secret of her ambition to beat Mr. Abe in a leadership contest next month, has just published a book called "Grab the Future", her public declaration for pulling Japan into line with "global standards". She has almost no chance of winning.

    The search engine Google celebrated on Thursday the 110th birthday of the first Native American woman engineer. Google honored Mary Ross with a special Google Doodle on its homepage.

    Ross was born on August 9, 1908, in the state of Oklahoma. She was the great-granddaughter of John Ross, the longest—serving chief of the Cherokee Nation. Her work is considered important to the early stages of the age of space travel.

    Ross showed special abilities in math and science from an early age. As a student, she developed an interest in aviation, or the practice of flying aircraft. She went on to earn a master's degree in mathematics from Colorado State Teachers College, now called the University of Northern Colorado.

    During World War II, Ross began working for the Lockheed Aircraft Corporation as a mathematician. She earned a special certification in the field from the University of California in1949.Ross was later chosen to join Lockheed's top—secret Skunk Works team that worked on aircraft designs. The name refers to a group that is permitted to work independently on advanced projects. She was the only female engineer among the team's 40 members.

    Early on, she researched defense systems. By the late 1950s, her work centered on satellites and a series of space rockets called Agenda. The rockets were extremely important in the 1960s during the Apollo moon program.

    Ross also helped develop early design ideas for space travel between planets, including flyby space flights to study Venus and Mars. Ross retired from Lockheed in 1973.But she continued to give talks at high schools and colleges to encourage more women and Native Americans to study engineering. She died in 2008, a few months before her 100th birthday.

    Many celebrated Ross' life on social media. Twitter user Aaron Perez, for example, wrote: “Mary Ross was an engineer who pioneered in the field of satellites. I never would have known if it wasn't for the doodle. Women engineers deserve more recognition.”

    Have you ever wished you could grow fresh fruit in your garden but worry about there not being enough space, or it won't look pretty, or it's too difficult?

    What if I was to tell you that even a beginner can successfully grow a wide variety of fruit from apples and pears to cherries, blueberries and raspberries, and possibly even figs or nectarines?

    The first thing you need to know: the sweeter the fruit, the more sun it will require. If you have a sunny wall it's an ideal place to train a sun-loving fruit tree like a peach or an apricot. Plant the tree at the base of the wall but not too close (about 30cm is about right) in soil enriched with fertilizer (肥料). As it grows, splay (整枝) the branches evenly and attach them to the wall. As the plant grows gradually cut out old untidy branches and tie in new healthy branches. The idea of splaying or “fanning” is that as much sun as possible gets to the fruit, so it can ripen beautifully and maximize your crop.

    Choose a variety that won't grow too large. In slightly shadier spots you can grow gooseberries or raspberries. Most of these come in compact (紧凑的) varieties and can also be fan-trained against a wall if space is an issue.

    I have a tiny orchard (果园) of space-saving apple, pear and plum trees bought as single vertical stems (茎) which I grow in pots. They grow to a maximum of 2m high and no wider than 45cm. My children love them! Simply cut back the side stems to about 10cm at this time of year and you're good to go. Just remember that pot-grown plants rely totally on you for their food and water.

    As a gardener I was quite late to fruit-growing, but I realized quickly that it becomes an addictive hobby. And as a complete bonus I've noticed a definite increase in my bee population over the past few years. There's free food, and it's good for the environment too. What could be better?
