●Approach whales from the side,not from the front or the back. ●Approach no closer than 100 metres,then stop the boat but keep the engine on. ●Keep noise levels down-no horns,whistles or racing of engines. ●Start your boat only after the whales are more than 100 metres from your vessel. ●Leave the area slowly,gradually moving faster when you are more than 300 metres from the whales. ●Approach and leave slowly,avoiding sudden changes in speed or direction. ●Avoid disturbing groups of resting whales. ●Keep at low speeds and remain in the same direction if travelling side by side with whales. ●When whales are travelling close to shore,avoid crowding them near the shore or coming between the whales and the shore. ●Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales. ●If there is more than one vessel at the same observation spot,be sure to avoid any boat position that would result in surrounding the whales. ●Work together by communicating with other vessels,and make sure that all operators are aware of the whale watching guidelines. 60.

Bush's No Child Left Behind program is an improvement on a good thing. But it doesn't go far enough. Obama outlined a goal that by 2020, all grade school and high school students are on a path toward college. However, what we need is a practical plan that not only requires all high school graduates to take at least two years of college but also makes it financially possible for them to do so. We've provided a free public education through the 12th grade. If we're going to keep up—or catch up——with some other countries (like China) in preparing young people for careers, a 12-year education programme no longer is enough. About 3 million students across the US will graduate from high school this spring. But only 2 million will go on to college, according to a survey by the National Centre for Education Statistics (NCFES). For the more than 1 million who won't go on, money is a main reason. If tuition(学费) were free, about half of them could make up other costs from family or part-time jobs. Critics (批评家) of free college tuition will say we can't afford it because of the federal deficit (联邦赤字) and other rising costs. Let's see some government spending in detail: In the last nearly 10 years, the wars in Iraq and Afghanistan have cost us $ 1,000 billion. Federal money which was spent on public primary and secondary education in the last year for which figures are available was $ 47 billion. If we end costly and unnecessary wars and nation-building efforts abroad, the federal government could provide more money on public education, for which state and governments now carry most of the burden. 63. What's the program No Child Left Behind about this year? A. All children being taken good care of by the government. B. All grade school and high school students receiving college education. C. No child being left alone at home. D. All children having good jobs in the future. 64. The author probably agrees that President Obama's plan ________. A. has nothing to do with George W. Bush's program. B. will surely succeed in ten years C. is about 12-year education for all the children D. doesn't contain practical measures(措施) to achieve its goal 65. If tuition were not paid for, about ________ American students could afford college education. A. 3 millionB. 2.5 millionC. 2 millionD. 1 million 66. What can we learn from the passage? A. The wars in Iraq and Afghanistan were necessary. B. The federal government has enough money for the plan. C. Critics of free tuition think highly of the plan. D. Obama's plan might be difficult to carry out. D One woman in nine will develop breast cancer (乳腺癌) over her lifetime. However, a healthy diet can reduce your risk of developing the disease by 40 to 60 percent. Generally speaking, eating more vegetables can reduce your risk of developing breast cancer by 60 percent. Vegetables like cabbage are rich in fiber (纤维), can lower your risk of developing breast cancer. To get the most from their goodness, it's recommended that you eat at least three to four cups of these vegetables per week. It's the oleic acid (油酸) contained in olive oil. American scientists conducting laboratory research have observed that oleic acid has a beneficial effect on breast cancer cells. Olive oil is the richest source of this acid, so whenever possible, use it in place of butter. Eating fruit is another excellent way to help prevent the development of breast cancer. In fact, women who do eat fruit are six percent less likely to develop the disease. The American Institute for Cancer Research considers berries (浆果类) (blueberries, strawberries, etc.) to be powerful for breast cancer fighters. It's the lycopene (番茄红素), found in great quantities in tomatoes, that can reduce the risk of developing breast cancer. The lycopene found in canned tomatoes is more readily absorbed by the body than that contained in fresh ones, so add tomato juice, paste, and sauce to your diet. (责任编辑：admin) |
