When people {#blank#}1{#/blank#} (face) with health or nutrition questions, it is {#blank#}2{#/blank#} (increasing) common to go online and diagnose themselves. But the Internet is full of conflicting health warnings with no regulation to get rid of the wrong advice, some of which {#blank#}3{#/blank#} (be) extremely dangerous! Also, search engines rank results by {#blank#}4{#/blank#} (popular) rather than accuracy, so solid facts can be tricky to find. It is worth {#blank#}5{#/blank#} (check) if the writer of an online piece is properly qualified as an expert. Anyone can call {#blank#}6{#/blank#} (they) a "diet expert", "nutritionist" and even a "doctor" — given it could refer to qualifications like a PhD. But remember, only officially {#blank#}7{#/blank#} (recognize) practicing doctors as well as dietitians have degrees in giving medical {#blank#}8{#/blank#} (suggest). So if you are unsure and still wondering {#blank#}9{#/blank#} the chocolate diet really does work or not, then it pays to make {#blank#}10{#/blank#} appointment with your dietician or doctor. The truth is out there, and you just need to look in the right place!

    For those who just love to shop online, Nov 11. is the{#blank#}1{#/blank#}(good) time of the year. Online group buying is quite popular{#blank#}2{#/blank#}the young. The main reason is that things in this way are{#blank#}3{#/blank#}(cheap) than those bought in usual stores. Then, it is convenient to {#blank#}4{#/blank#}(make) orders and pay. Besides, it is a trend and young people love following trends. {#blank#}5{#/blank#}, every coin has two sides. Online group buying has{#blank#}6{#/blank#}(advantage). It is sometimes unsafe. One of my friends was {#blank#}7{#/blank#}(cheat) once. He bought {#blank#}8{#/blank#}MP4 on a group buying site. Several days passed, he still didn't receive the MP4. He called to find out{#blank#}9{#/blank#}the problem was, and found that the site was a trick. Therefore, we must be careful when{#blank#}10{#/blank#}(do) such shopping. In addition, buy only what we need and never buy unnecessary things just because they are cheap.

    Trust is a tricky business. On the one hand, it's a necessary condition for many worthwhile things such as child care or friendships. On the other hand, {#blank#}1{#/blank#} (put) your faith in the wrong place often carries a high price.

    Then, why do we trust at all? Well, because it feels good. {#blank#}2{#/blank#} people place their trust in an individual or an institution, their brains release oxytocin, a hormone that produces pleasurable feelings and triggers the herding instruction that leads sheep to flock together for safety and prompts humans {#blank#}3{#/blank#} (connect) with one another.

    Swiss Scientists have found that exposure{#blank#}4{#/blank#} this hormone puts us in a trusting mood: In a study, researchers sprayed oxytocin (催产素) into the noses of half the subjects; those subjects were ready to lend significantly {#blank#}5{#/blank#} (high) amounts of money to strangers than were their counterparts{#blank#}6{#/blank#}inhaled something else.

    Lucky for us, we also have a sixth sense for dishonesty that {#blank#}7{#/blank#} protect us. A Canadian study found that children as young as 14 months can differentiate between a credible person and a dishonest {#blank#}8{#/blank#}. Sixty toddlers were each introduced to an adult tester holding a plastic container. The tester would ask, "What's in here?" before looking into the container, smiling, and exclaiming, "Wow!" Each subject was then invited to look inside. Half of them found a toy; the other half discovered the container was empty-and realized the tester {#blank#}9{#/blank#} (fool) them.

    Among the children who had not been tricked, the majority were willing to cooperate with the tester in learning a new skill, demonstrating that they trusted his leadership. In contrast, only five of the 30 children {#blank#}10{#/blank#} (pair) with the "inflexible" tester participated in a follow-up activity.

Keep Your Eyes Open for Weight Loss Ads

    "In only six days I lost seven pounds of weight."

    "Two full inches in the first three days!"

    These are the kinds of statements {#blank#}1{#/blank#} (use) in magazine, newspaper, radio and television ads, {#blank#}2{#/blank#} (promise) new shapes and new looks to those who buy the medicine or the device. The promoters of products say they {#blank#}3{#/blank#} shape the legs, slim the face and smooth wrinkles. Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.

    To understand how these products can be legally promoted to the public, {#blank#}4{#/blank#} is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration) can require proof that it is safe and effective before it {#blank#}5{#/blank#}(put) on the market. But if the product is a device, FDA has no authority {#blank#}6{#/blank#} (require) premarketing proof of safety or effectiveness. {#blank#}7{#/blank#} a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure(查封) of the product.

    One notable case a few years ago {#blank#}8{#/blank#}(involve) an electrical device called the Relaxacisor, {#blank#}9{#/blank#} had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds {#blank#}10{#/blank#} it was dangerous to health and life.
