    Newton's law of motion ( 运动定律）.where every action has a reaction, is appropriate not just to physics. 1. from the value of products and prices of produces to customer choices, advertising affects society and plays an important role in increasing business sales.

2. When companies use advertising, sales increase, according to Marcel Bleustein-Blanchet, founder of a French advertising company. The increase in business sales also promotes the quality of life for consumers. Basically, advertising causes a chain reaction that increases the economy of the area where the product or service ad is.

3. In the minds of consumers, advertising can add value to a product. The image or brand that advertising helps to create becomes a part of the product, which is what makes one product brand more valuable than the competitors. This is why a consumer may be willing to pay a higher price for a name brand product rather than buy a brand they are not familiar with at a lower cost.

Pricing. 4. It spurs （促进）a sense of competition. When one company advertises a product for its price, its competitors want to stay competitive. Then they may lower their prices to meet the competition.

Consumer choice. Advertising also has an influence on businesses because it leads to the creation of new products and improvement of existing products to meet consumers' needs. 5.However, when advertising introduces a new product that is better than the existing one. market share can quickly shift to the company offering the newly-advertised product.

A. Product value.

B. Product quantity.

C. Economic influence.

D. Advertising can be a form of price control.

E. An increase in competition has effects on the market.

F. One company may possess a larger share of the market for a time.

G. It is also true that advertising causes reactions that occur in society and business.

    Exercise may hold the key to youth, according to a study published on Monday which showed people who keep fit are up to nine years biologically younger than those who do not. The findings are the first to show in humans how keeping fit affects the ageing process.

The study of 2,40twins found that a sedentary（久坐的）lifestyle raises the risk of a range of problems from heart disease to cancer and appears to play a key role in the ageing process.

It all appears to boil down to（归结为）the length of structures called telomeres（染色体终 端）---which protect the DNA on the chromosomes（染色体）,the researchers from King's College London wrote in the Archives of Internal Medicine.

Many studies have shown telomeres get shorter over time, suggesting the cells are ageing or dying. The study, which extracted （提取）a DNA sample from their volunteers, found people who exercised more each week had longer telomeres.

Exercise lowers the risk of a range of problems such as heart disease, diabetes and cancer, the researchers said. “It is not just walking around the block. It is really working up a sweat." said Tim Spector, a genetic epidemiologist who led the study, in a telephone interview.

The study found people who exercised energetically 3 hours each week had longer telomeres and they were 9 years biologically younger than people who did under 15 minutes.

Spector's team, who also adjusted for body weight, smoking, economic status and physical activity at work, also said moderate（适度的）exercise for 1-2 hours each week provided a four- year advantage.

Studying twins also provided a unique opportunity to judge the effects of exercise on people with the same or similar genetic make-up. the researchers said.

The reason why exercise has this effect is not clear but the researchers said they believe physical activity somehow defends against the natural process called oxidative stress （氧化应激反应）.which damages and kills cells.

4.What is the purpose of the text?

A.To introduce some exercise.

    Short-term overseas visitors can now use mobile payments on the Chinese mainland. China's leading mobile payment company Alipay backed by Alibaba announced on Tuesday.

The digital payment giant just introduced an international version of its popular app. designed for overseas travelers to provide them with convenience when paying with their smartphones for shopping, eating and traveling in the Chinese mainland, according to Alipay.
