Microsoft founder Bill Gates said that he planned to give away almost all of his fortune ,largely to the cause of global health,during the course of his lifetime.With an estimated worth of more than $40 billion,according to Forbes,the project will be no small fate for Gates.Having already provided the Bill & Melinda Gates Foundation with $24 billion to address global health issues,Gates said that finally his entire fortune will be put towards the cause except "a few percent left for the kids". So what has made the richest man in the world to channel his resources so heavily into one interest?Gates believes that "the equality of opportunity "in which Americans take such pride needs to extend to other nations around the world. Improving the health of the populations,he says,has proven to be an essential method in helping poor countries to be financially successful."National borders allow inequalities,"said Gates."We all need to take a more global view,rather than just saying my country is doing well.We have to step up these health issues,knowing how few resources are going into them." Gates said that both his parents set up an example for him as a child.His father,William H.Gates,was the head of the local Planned Parenthood,and his mother,Mary,volunteered for the United Way.As he gathered his fortune,Gates knew he would finally want to give back as well,but he didn't expect to devote himself wholeheartedly to one project until he was about 60. However,Gates,47,began to question his ability to wait that long."It seemed there was a real time urgency,"Gates said."I started to think how many lives I could save before then." Bill Gates believes that one important way of developing poor countries is _ . A) to set up more foundations for them B) to help them with natural resources C) to put more efforts into the health issues in them D) to help them take a more global view

(Question)
The Hawaiian Islands are situated about two thousand miles away from North America, right in the middle of the Pacific Ocean. Despite the distance the islands actually make up the fiftieth state of the United States. The islands were all formed by volcanic eruption and on the largest of the islands, Hawaii, or the Big Island, there are still two active volcanoes, the Mauna Loa and the Kilauea, which still erupt every few years. On the Hawaiian islands the natives have a particularly strange way of indicating directions. They don't use the north, south, east and west system common to the rest of the world. They use the mauka andmakaisystem.Maukameans "mountain". The mountains in Hawaii are always at the center of the islands, as these are volcanic islands.Makaimeans "the sea". The islands are small and the system is simple. Wherever you want to visit, it can always be described in terms of where it lies in relation to the mountains and the sea. A typical conversation between a native Hawaiian and a tourist might go as follow. TOURIST: Excuse me! Could you tell me where the Sheraton Hotel is? HAWAIIAN: Well... Let me see! From here it's two blocks mauka, and then one blockmakai. You can't miss it! Which of the following items does the passage NOT discuss? A) Hawaii's location. B) How to give directions in Hawaii. C) Volcanoes. D) The climate.

Ques: People who eat chocolate regularly tend to be thinner, new research suggests. The findings come from a study of nearly 1,000 US people that looked at diet, calorie intake and body mass index(BMI)----a measure of obesity. It found those who ate chocolate a few times a week were, on average, slimmer than those who ate it occasionally. Even though chocolate is loaded with calories, it contains ingredients that may favour weight loss rather than fat synthesis , scientists believe. Despite boosting calorie intake, regular chocolate consumption was related to lower BMI in the study. The link remained even when other factors, like how much exercise individuals did, were taken into account. And it appears it is how often you eat chocolate that is important, rather than how much of it you eat. The study found no link with quantity consumed. Lead author Dr. Beatrice Golomb, from the University of California at San Diego, said, "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight." This is not the first time scientists have suggested that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart. Consumption of certain types of chocolate has been linked to some favourable changes in blood pressure and insulin sensitivity. And chocolate does contain antioxidants which can help to absorb free radicals----unstable chemicals that can damage our cells. Mice fed for 15 days with epicatechin (present in chocolate) had improved exercise performance and observable changes to their muscle composition. They say clinical trials are now needed in humans to see if this is the case. But before you reach for a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution. While there's no harm in allowing yourself a treat like chocolate now and then, eating too much might be harmful because it often... According to the passage, chocolate may be healthy for us in the following EXCEPT that . A) it may make us more cheerful B) it may do good to the heart C) it might prevent us from becoming obese D) it may control blood pressure
Ans: A
The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public. For example, at many public exhibitions about energy, SPS is not even mentioned. This is mainly because very little money has been spent on SPS research There are people who claim that SPS is unrealistic - because launch costs are much too high today; or because it is too far away. So why do we believe that it is important to continue to do researches on SPS? The reason is very simple. Humans are going to need huge amounts of electric power in coming decades. Within 50 years the world population is expected to double, while economic growth will continue around the world, especially in the poorer countries. But existing energy sources already face serious problems. They are limited; they are polluted; they are dangerous. So 50 or 100 years from now, where is our power going to come from? Nobody knows. And so we believe that new large-scale possibilities should be studied further. We must remember that humans have some choices concerning our future. To some extent we can choose the direction in which our civilization develops. And choices that are made in the coming decades - such as the energy sources that we will or will not use, will have major, long-term meaning for human life on earth. We believe that if research continues to show that SPS is environmentally and economically attractive, SPS will open the door to a much more attractive future for human civilization than any ground-based energy source, and one that the public will support and that young people will find challenging and exciting. Furthermore energy from SPS can be readily used in developing countries, as the SPS 2000 project will show, thus aiding economic development worldwide. In addition, by creating large commercial fund for space engineering, SPS will open the frontier of space to economic development, thus creating a limitless new field for the growth of the world economy. Which of the following statements about SPS is TRUE? A) The research on SPS started in the 1960s is still not appreciated by the public. B) The research is showing SPS can benefit environment and economy at present. C) The energy from SPS is now being used in some developing countries. D) The public don't know about SPS because little time is devoted to the research.
