This is because food attracts germs(細菌), germs produce acid, and acid hurts your teeth and gums.(長時間讓食物停留在牙齒是有害處的，這是因為食物能吸引細菌，細菌會產生酸，腐蝕你的牙齒)，故選A項。( 2 )句意猜測題。Not every doctor agrees about these ideas不是每個醫(yī)生都對這些問題持相同的態(tài)度，Some doctors think that the link between good flossing habits and good heart health is only a , some doctors think that people who have bad flossing habits just happen to also have heart problems一些醫(yī)生認為有剔牙習慣的碰巧有心臟問題，故是發(fā)展以前的觀點，因此選D項。( 3 ) 段落大意題。根據最后一段提到剔牙能保持你的心臟健康這一理論可能并不正確的，但醫(yī)生同意剔牙能保證牙齒的健康，因此即使剔牙不能有助于你的心臟，肯定能保護你牙齒，這就是每天剔牙的重要原因，故選D項。( 4 )主旨標題題。本文提到經過研究，剔牙與保持心臟之間沒有必然的聯系，但剔牙能保護牙齒的健康是可以肯定的，故選C項。4．閱讀理解 The Women39。s Institute is urging supermarkets to do more to help consumers reduce their home food waste, after a survey of its own membership showed widespread confusion about “best before” and “use by” labeling(標簽) on packaging. Its new analysis of products on supermarket shelves found that “onceopened” instructions were often contradictory and often failed to make clear whether they were a guide to food safety or quality. Only 45% of 5,000 WI members surveyed understood that bestbefore dates were a sign of food quality, while 26% did not understand that the more important useby dates were a decisive guide to food safety. In its report on food waste, the WI said supermarkets were “potentially contributing to home food waste by leading customers to buy more food than they need, and giving conflicting and confusing onpack information that leaves customers unsure about how long a product remains safe to eat in the home setting”. The 42page report is part of the WI39。s ongoing campaign to reduce food waste. To underline the point about conflicting information, it cites(引用) a can of Sainsbury39。s ownbrand sweetcorn advising consumers to eat it within one day of opening, while a similar tin from Waitrose gave consumers two days to finish it. Green Giant sweetcorn, however, has no specified date for eating once opened. Marylyn Haines Evans, chair of the Women39。s Institute39。s public affairs said: “WI members are some of the more informed members of society about food and cookery, but they are still confused about food labelling and 39。onceopened39。 information. So we would like supermarkets to extend the amount of time that consumers have to use a product in their homes by making all of their onceopened instructions on product packaging consistent, and pletely remove onceopened instructions on products where food safety is not an issue.”（1）What mainly leads to food waste according to WI?A.Poor quality of food.B.Attractive packaging of products.C.Competition among supermarkets.D.Consumers39。 confusion about onpack information.（2）Which of the following can inform you of food safety?A.B.C.D.（3）Why are the three supermarkets mentioned in Paragraph 3?A.To attract more consumers.B.To pare their products.C.To ment on their service.D.To make WI39。s report convincing.（4）What does Evans suggest supermarkets do about reducing food waste?A.Extend life of a product.B.Turn to wellinformed WI members.C.Give consistent onceopened instructions.D.Remove instructions on product packaging.【答案】 （1）D（2）C（3）D（4）C 【解析】【分析】本文主要講述了婦女機構強烈建議超市采取幫助消費者減少食物浪費的措施，比如延長消費者在家中使用產品的時間，使他們所有曾經打開的關于產品包裝的說明一致。 （1）細節(jié)理解題。根據第二段Only 45% of 5,000 WI members surveyed understood that bestbefore dates were a sign of food quality, while 26% did not understand that the more important useby dates were a decisive guide to food safety.可知，消費者對于食品包裝上信息的混淆是導致食物浪費的原因。故選D。 （2）細節(jié)理解題。根據第二段while 26% did not understand that the more important useby dates were a decisive guide to food safety.可知，use by信息才是食品安全的決定性指導因素。故選C。 （3）細節(jié)理解題。根據第三段To underline the point about conflicting information, it cites(引用) a can of Sainsbury39。s ownbrand sweetcorn可知，引用超市的例子是為了更好的說明這一問題，即使文章更具說服力。故選D。 （4）細節(jié)理解題。根據最后一段we would like supermarkets to extend the amount of time that consumers have to use a product in their homes by making all of their onceopened instructions on product packaging consistent,可知，為了減少食物浪費，超市可通過使包裝帶上的信息一致來達到這一目的。故選C。5．閱讀理解 Our mother earth is going through a very tough situation and we, the entire human race, are destroying our environment or unconsciously without even realizing its consequences. Now we have to act very smartly and plan something to sustain what we still have, getting all necessary support from nature to lead healthy lives. Gardening is always an excellent and environmentally friendly idea. If you can go for sustainable gardening, then it will be even more useful for all. Gardening is a favorite hobby for many. It is time to channelize your hobby towards a more meaningful motivation. When we do gardening we need to use different ingredients to grow plants. Some of them are natural resources like water, soil, sunshine, and many things like this. Using these resources smartly is a part of sustainable gardening. Some simple techniques include: use less water and organic things to grow plants。 try to store rainwater so that you can use them for gardening。 try using less energy to drive devices。 avoid using plastics in any form while gardening。 reuse the leaves from your garden to fertilize them. These are the basic sustainable measures. To do so we need to have proper knowledge about gardening and its requirements so that we can use proper resources without wasting any of them. In today39。s busy life we don39。t get much time to spend on our environment. Gardening gives us a chance to do so. We can also have some pesticidefree and fresh food if we grow them in our garden. This is the right time to do some good
