Still, I kept the porch light off because I didnt want to be surrounded by bugs and moths(飞蛾)on this sticky summe

10、r evening. I stood there for a while letting my eyes adjust to the lack of light. My dog stood beside me waiting patiently for me to start her walk. It was then, though, that I saw them. First one blink of light at the far end of the meadow was followed by another and then another. I smiled. I recog

11、nized them at once as my firefly friends, who always showed up this time of the year.I got so much joy watching them first as a child and then as an adult. They never became dull or boring and they always filled me with delight. When I was little I used to sit in the grass and watch them slowly fly

12、around blinking on and off. I never caught and put one in a jar as some kids did because I was afraid I might kill it and I never wanted to hurt these messengers(信使)of light. Their time on this earth was so brief as it was. I tried to enjoy them each night they were here. It always saddened me when

17、.Lead author Dr. Chayakrit Krittanawong said: Our study suggests chocolate helps keep the hearts blood vessels healthy. It collected data from six trials that examined the link over the past five decades. A total of 336, 289 people reported their intake. Those who ate chocolate more than once a week

18、 reduced their risk of coronary artery(冠状动脉)disease by eight percent. This was compared with peers who ate it less than once a week.Chocolate is known to produce the same chemical in the brain as falling in love. But evidence is growing that its reputation as a guilty pleasure is wrong. Dr. Krittana

19、wong said: Chocolate contains heart healthy nutrients such as flavonoids, methylxanthines, polyphenols and stearic acid which may reduce inflammation.Known medically as HDL (high-density lipoprotein)(高密度脂蛋白), it helps to rid LDL (low-density lipoprotein)out of the body. When this collects, it causes

20、 vessels and arteries to become blocked up. It can stop blood flow to the heart or brain, causing a heart attack or stroke. Dr. Krittana-wong said: In the past, clinical studies have shown chocolate is beneficial to blood pressure.Dark chocolate has long been known to have health benefits but recent

21、 research has suggested milk chocolate may also provide valuable nutrients to the heart. Dr. Krittanawong pointed out his study did not investigate whether any particular type of chocolate is more beneficial-or if there is an ideal portion size. He said: Chocolate appears promising for prevention of

22、 coronary artery disease. But more research is needed to show how much and what kind of chocolate could be recommended.While its not clear how much is perfect, Dr. Krittanawong warned against overeating. He said: Moderate amounts of chocolate seem to protect the coronary arteries but its likely that

23、 large quantities do not.28. What does Paragraph 2 mainly talk about?A. The result of the study. B. The process of the study.C. The participants of the study. D. The intention of the study.29.

24、rotein. D. Low-density lipoprotein.30. What does the recent study tell us?A. Chocolate is good for blood pressure. B. Dark chocolate is beneficial to health.C.

25、ates preventing coronary artery disease?A. Indifferent. B. Hopeful. C. Negative. D. Uncertain.DEuropean researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the

26、future.Researchers from the European Space Agency, or ESA, carried out the experiments at a laboratory in the Netherlands. They reported their results in a study published in Planetary and Space Science.The team says ESAs experimental plant was able to successfully produce oxygen from simulated moon

27、 dust. The dust is part of a material known as regolith(月壤), a top layer of dirt and rock pieces that sit on the surface of the moon.Samples of regolith from the moon have confirmed that the material contains about 45 percent oxygen by weight. However, the oxygen is chemically locked in the form of

28、minerals or glass, so it is not easily available for use. Having real samples of regolith from the moon made it possible for the researchers to create the simulated moon dust material used during testing.The oxygen extraction(提取)process is carried out using a method called molten salt electrolysis(熔

29、盐电解). This involves first placing the regolith in a metal container. Calcium chloride salt is added to the mixture, which is then heated to 950 degrees Celsius. At this temperature, the regolith remains solid. Next, an electrical current is passed through the material. The researchers say it is this

30、 step that results in oxygen being extracted from the regolith. The study reported that up to 96 percent of oxygen in the simulated moon dust was extracted during the experiments.ESAs long-term goal is to design an oxygen-producing pilot plant to operate full-time on the moon. The first technology d

31、emonstration of the system is expected to take place in the middle of 2020s.The researchers reported that as a bonus, the process also results in the production of usable metallic materials.32. What can benefit from the process?A. The treatment of some patients. B. The environment of the moon.C. Fut

32、ure moon exploration activities. D. Future experiment in the laboratory.33. Why is oxygen in the regolith hard to use?A. It exists in the form of solid. B. It only exists on the surface.C. It is mixed with other materials. D. It is locked in a metal container.34. What step makes oxygen extracted from the regolith?A. Adding calcium chloride salt to the mixture.B. Placing the regolith in a metal container.C. Passing an electrical current through the material.D. Heating the metal container to 950 degrees Celsius.
