Manufacturers of products that claim to be environmentally friendly will face tighter rules on how they are advertised to consumers under changes proposed by the Federal Trade Commission.The commission's revised "Green Guides" warn marketers against using labels that make broad claims, like "eco-friendly". Marketers must qualify their claims on the product packaging and limit them to a specific benefit, such as how much of the product is recycled."This is really about trying to cut through the confusion that consumers have when they are buying a product and that businesses have when they are selling a product, " said Jon Leibowitz, chairman of the commission.The revisions come at a time when green marketing is on the rise. According to a new study, the number of advertisements with green messages in mainstream magazines has risen since 1987, and peaked in 2008 at 10.4%. In 2009, the number dropped to 9%.But while the number of advertisements may have dipped, there has been a rapid spread of eco-labeling. There are both good and bad players in the eco-labeling game. In the last five years or so, there has been an explosion of green claims and environmental claims. It is clear that consumers don't always know what they are getting.A handful of lawsuits have been filed in recent years against companies accused of using misleading environmental labels. In 2008 and 2009, class-action lawsuits(集体诉讼)were filed against SC Johnson for using "Greenlist" labels on its cleaning products. The lawsuits said that the label was misleading because it gave the impression that the products had been certified by a third party when the certification was the company's own."We are very proud of our accomplishments under the Greenlist system and we believe that we will prevail in these cases, " Christopher Beard, director of public affairs for SC Johnson, said, while acknowledging that "this has been an area that is difficult to navigate."Companies have also taken it upon themselves to contest each other's green claims. David Mallen, associate director of the Council of Better Business Bureau, said in the last two years the organization had seen an increase in the number of claims companies were bringing against each other for false or misleading environmental product claims. "About once a week, I have a client that will bring up a new certification I've never even heard of and I'm in this industry, " said Kevin Wilhelm, chief executive officer of Sustainable Business Consulting. "It's kind of a Wild West, anybody can claim themselves to be green." Mr. Wilhelm said the excess of labels made it difficult for businesses and consumers to know which labels they should pay attention to.What do the revised "Green Guides" require businesses to do? A.ttach green labels to all of their products.B.Specify in what way their products are green.C.Manufacture as many green products as possible.D.Indicate whether their products are recyclable.What does the author say about consumers facing an explosion of green claims?

In another study, researchers asked volunteers to jog for 30 minutes and then showed them clips from a sad movie. Participants who usually struggled to handle negative emotions were more intensely affected by the sad clips just as you'd expect. But crucially, this was less so if they had completed the 30 minutes jog. The researchers said moderate exercise appears to have helped those participants to be less vulnerable to the impact of the sad movie.Q: What did another study find about the participants after they had a 30-minute jog?听音频并回答音频中的问题A、They found it easy to control their emotions.B、They struggled to handle negative emotions.C、They were more eager to enjoy a movie.D、They were less affected by sad movies.

Though feelings of 2. decrease, feelings of love actually grow, however. Some might find this 3. , but there are significant examples that prove this point. To begin with, the 4. of marriages actually rises. Soldiers going to war, afraid that they will not return, take advantage of the time before their5. to find love and get married. Also, people caught up in dangerous territory hurry into 6. relationships such as marriage. This is because, like the soldiers, they don't know how long they have to live.

By far the most common difficulty in study is simple failure to get down to regular concentrated work. This difficulty is much greater for those who do not work to a plan and have no regular routine of study. Many students muddle along, doing a bit of this subject or that, as the mood takes them, or letting their set work pile up until the last possible moment. Few students work to a set timetable. They say that if they did construct a timetable for themselves they would not keep to it, or would have to alter it constantly, since they can never predict from one day to the next what their activities will be. No doubt some temperaments take much more kindly to a regular routine than others. There are many who shy away from the self-regimentation（严格控制）of a weekly timetable, and dislike being tied down to a definite programme of work. Many able students claim that they work in cycles. When they become interested in a topic they work on it intensively for three or four days at a time. On other days they avoid work completely. It has to be confessed that we do not fully understand the complexities of the motivation to work. Most people over 25 years of age have been used to a work routine, and the majority of really productive workers set aside regular hours for the more important aspects of their work. The “tough-minded” school of workers is usually very contemptuous （蔑视的） of the idea that good work can only be done spontaneously, under the influence of inspiration. Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of “freedom”. Freedom from discipline leads to unhappiness rather than to “self-expression” or “personality development”. Our society insists on regular habits, timekeeping and punctuality, and whether we like it or not, if we mean to make our way in society we have to comply with its demands. 76. The most widespread problem in applying oneself to study is that of _____. A. the failure to keep to a routine of intensive work B. changing from one subject to another C. willingness to follow a systematic plan D. applying oneself to a subject only when one feels inclined 77. Those workers with strict views on work _____. A. are very critical of the belief that good work can be a natural product of instinct B. reject the idea that good work is second nature to man C. do not regard as serious the opinion that good work can be done at any time regardless of inspiration D. pay no attention to the idea that good work can only be done when they are prompted by internal stimulus 78. In Paragraph 4 “as the fit takes them” means _____. A. when they have the energy B. when they are in the mood C. when they find conditions suitable D. when they feel fit 79. A suitable title for the passage might be _____. A. Attitudes to Study B. Study Plans C. The Difficulties in Study D. Study and Self-discipline
