But to the heart of the problem, we have to stop producing and using so much plastic.（1）What makes it difficult to know microplastics monly exist in the human body? quality. quantity. shape. size.（2）How did Kieran Cox39。The authors of the study found that people who drink exclusively from plastic water bottles absorb an additional 90,000 microplastics each year, pared to 4,000 among those who only consume tap water. This shows that small decisions, over the course of a year, really matter and have an impact. Cox says. The new study, according to its authors, was the first to investigate the accumulative human exposure to microplastics. But in all likelihood, the research tells only a small part of the entire story. Collectively, the food and drink that the researchers analyzed represent 15 percent of Americans39。Hoping to fill in some of these gaps, a research team led by Kieran Cox, a PhD candidate at the University of Victoria, looked at 26 papers assessing the amount of microplastics in monly consumed food items, among which are seafood, sugars, salts, honey, alcohol and water. The team also evaluated the potential consumption of microplastics through inhalation (吸入)using previously reported data on microplastic concentrations in the air and the Environmental Protection Agency39。 s hardly surprising that the tiny fragments have also been found in humans. A new study shows that Americans are consuming as many as 121,000 particles each year. 8．閱讀理解 根據最后一段中的“ Just like the continuing rain while we went up the Eiffel tower, every cloud has a silver lining, because then we got the funniest photos ever!”可知，雖然作者和家人在雨中登上埃菲爾鐵塔，但是在云彩的襯托下他們所拍的照片非常美，作者對待困難的態(tài)度非常積極，由此可知，故選C。根據第三段中的“Despite the fact that I felt the slight pressure to make sure the weekend went smoothly, even the heavy rain failed to dampen our mood.”可知，作者帶著母親和妹妹在巴黎游玩地非常高興，由此可知大雨沒有破壞她們的情緒，故選B。根據第二段可知，作者的妹妹喜歡音樂，她便想盡一切辦法給妹妹買到音樂會演出的票，做了一個名副其實的好姐姐，由此可知，選D。根據第一段可知，身在異鄉(xiāng)的作者也會時不時地思念家中的親人，故選C。She is skilled in taking photos.【答案】（1）C（2）D（3）B（4）C 【解析】【分析】本文是一篇記敘文，作者以自己的親身經歷，告訴讀者：想家是在外的學子們的共同感受，在異鄉(xiāng)看到親人時的感覺是難以用語言去形容的。She has a positive attitude.B.Remind.（4）How does the author describe herself in the passage?
