Body language ***閱讀理解。 Vitamin B could help lessen the effects of the most dangerous type of air pollution, according to a new study published recently. In the first study of its kind, a team of international researchers looked at the damage caused by one of the pollutants that have the most severe impact on health: PM2.5. Particulate matter, or PM, is a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometers, about 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system(呼吸系統(tǒng)), resulting in lung and systemic inflammation(炎癥) and stress. The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body, although they stressed that the research was in its early stages and the sample size was small. For this study, 10 volunteers were initially exposed to clean air and given a placebo(安慰劑) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1，000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygentype” face mask. The experiment was then repeated, with each volunteer taking a B vitamin supplement daily made up of 2.5 mg of folic acid, 50 mg of vitamin B6, and 1 mg of vitamin B12. B6 can be found in liver, chicken and nuts, and B12 in fish, meat, eggs, milk and some cereals. The researchers found that four weeks of B vitamin supplements reduced the damage of PM2.5 exposure by 28%－76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5. 【解題導語】　本文是一篇說明文。吸入人體內(nèi)的PM2.5(細顆粒物)會導致疾病。不過，研究發(fā)現(xiàn)維生素B在一定程度上能降低PM2.5的危害。 1．Why is PM2.5 harmful to our health? A．It pollutes and poisons the air. B．It is too much to be got rid of. C．It carries viruses and diseases. D．It is easily breathed in and damages our body. D　解析：細節(jié)理解題。根據(jù)第二段中的“These particles are so small...inflammation(炎癥)and stress.”可知，PM2.5(細顆粒物)很小，能進入我們的呼吸系統(tǒng)，導致肺部和全身炎癥。 2．What can we infer from Paragraph 3? A．The process of the research was not scientific. B．This kind of research has been done many times. C．Further studies are needed to confirm their findings. D．Vitamin B is hard to obtain in people’s daily life. C　解析：推理判斷題。根據(jù)第三段中的“although they stressed that the research was in its early stages and the sample size was small.”可知，該項研究處于初級階段且樣本規(guī)模小，因此還需要更多的研究來證明研究團隊的發(fā)現(xiàn)。 3．What is the text mainly about? A．International researchers have a new finding. B．Vitamin B could reduce the damage of PM2.5. C．Particulate matter does great harm to our health. D．Emission control and regulation are badly needed. B　解析：主旨大意題。文章第一段和第二段談到PM2.5的定義以及PM2.5的危害；第三到五段告訴我們維生素B能降低PM2.5的危害。所以B項最能概括文章主旨。 4．The new study was probably published ___________ ． A．in a science journal B．on a government website C．in a fashion magazine D．in a medical textbook A　解析：推理判斷題。該文的內(nèi)容為科學研究發(fā)現(xiàn)，很可能出自科學期刊。所以A項正確。 ***語法填空。 After spending nearly every waking minute with Angel for eight straight days, I knew that I had to tell her just one thing.

The room was __4__ (peace)—almost silent.All I could hear was the soft voice of her breathing. I stayed awake __5__ (think) about the time we __6__ (spend) together and all the choices in our lives that made this moment possible. And at some point, I realized that it didnt matter what wed done or where wed gone. Nor __7__ the future hold any significance. What mattered was the calmness of the moment.

The other day, I was praised by my head teacher at the class meeting because I have recited all the words of Unit 3. He said before the whole class that only if we put our hearts into our lessons could we make great progress. He also said I set the good example to all of my classmates and that I memorized all the words of Unit 3 as though I was not good at English. He also added that everyone should learn from me. Hearing that the head teacher said, I was more than glad and my heart beat wildly. At the same time, I made up my mind to study hard rather than wasting precious time on those useless things, such as playing video games and chatting online. On my own experience, I learn that several words of praise can make a great difference to someone. 答案： As a student, I can tell you that there is better than praised by my teacher before my classmates.
