A film crew traveled the globe to document the rubbish. And Julie Andersen of the Plastic Oceans Foundation says what we see is just the tip of the problem. “Half of the waste actually sinks to the bottom, and that remains on the surface actually breaks down.”The filmmakers found rubbish in ocean gyres, the circulating currents that trap large concentrations of pollution in the Atlantic, Indian, and Pacific Oceans, home of what some have plastic. “What we found was a plastic smog that spread throughout all the water. And in some parts of the oceans, scientists have found more plastic than plant.”The pieces of the plastic garbage infect the food chain, sometimes visibly，and more so at the microscopic level, where the plastic particles interact with other pollutants. “There are heavy metals, medicines, industrial waste in the sea, while they acts like magnets (磁铁). These poisonous substances absorb on the plastic, and then when seafood absorbs the plastics, those poisonous substances enter the fatty tissues.” To be consumed by other sea life and by people at last.China, Indonesia, the Philippines, Thailand and Vietnam are the worst plastic polluters. The United States, although a leader in recycling, is one of the worlds 20 since it produces and consumes so much plastic. There are efforts around the world to address the problem, including at this newly opened recycling center in Lebanon (黎巴嫩). But Andersen says there is more that people can do. “Cut back on singleuse plastics, straws, plastic cups, plastic water bottles, plastic bags and find alternatives like reusable materials.” She says healthy oceans are essential to our survival.1What can we learn from the passage?ATheres all island full of plastic rubbish in the Pacific.BThe bad effect of plastic pollution cant be seen by eyes.CThe United States is the least plastic polluters.DThe plastic pollution to oceans is more serious than what we can see.答案：D细节理解题。根据第一段第三句“塑料海洋基金会的朱莉安德森说，我们看到的只是问题的冰山一角。”可推测塑料对海洋的污染比我们所看到的更严重，故选D。2What does the underlined word “they” refer to in Paragraph 3?APollutants like heavy metals and medicines.BThe plastic particles.CSeafood.DFatty tissues.答案：B词义猜测题。根据第三段中的“where the plastic particles interact with other pollutants”可知画线词所在句子表示“海洋中有重金属、药物、工业废物，而塑料颗粒起着磁铁一样的作用”。所以they指代的是塑料颗粒。故选B。3What can be inferred from the last paragraph?AAll Asian countries have the most serious problem of plastic pollution.BThe plastic problem hasnt attracted the worlds attention.CAndersen is not satisfied with what has been done to solve the plastic problem.DPeople should stop using plastic products immediately.答案：C推理判断题。根据最后一段第四句可知，安德森认为人们还可以做更多事情来预防污染，可推测出安德森对于目前解决塑料问题所做的工作不满意。故选C。4Which may be the title of the passage?APlastic pollution in the WorldBPlastic pollutionOceans DisasterCWays to solve the problem of plastic pollution to oceansDPlastic pollution and our health答案：B标题判断题。阅读全文可知，本文主要讲述了塑料污染对海洋的影响。故选B。读后续写阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。Jenny was the only child in her home. She had a quarrel with her mother that_afternoon and she ran out of the house angrily. She couldnt help weeping sorrowfully when she thought of the_scolding_from_her_mother. Having wandered aimlessly in_the_street for hours, she felt a little hungry and wished for something to eat, but it was not even possible for her, since she had nothing with her. She stood beside a stand for a while, watching the middleaged seller busy doing his business. However, with no money in hand, she sighed and had to leave.The seller behind the stand noticed the young girl and asked, “Hey, girl, you want to have the noodles？”“Oh, yes . but I dont have money on me . ” she replied.“Thats nothing. Ill treat you today，” said the man, “come in.”The seller brought her a bowl of noodles, whose smell was so attractive. As she was eating, Jenny cried silently.“What is it？” asked the man kindly.“Nothing, actually I was just touched by your kindness！” said Jenny as she wiped her tears. “Even a stranger on the street will give me a bowl of noodles, while my mother, drove me out of the house. She showed no care for me. She is so merciless compared to a stranger！”Hearing the words, the seller smiled “Girl, do you really think so? I only gave you a bowl of noodles and you thanked me a lot. But it is your mother who has raised you since you were a baby. Can you number the times she cooked for you? Have you expressed your gratitude to her？”Jenny sat there, speechless and numb with shock; she remembered mothers familiar face and weathered hands. “Why did I not think of that? A bowl of noodles from a stranger made me feel indebted, but I have never thanked my mum for what she has done for me.”On the way home, Jenny made up her mind to make an apology to her mother for her rudeness as soon as she arrived home.注意：1所续写短文的词数应为150左右；2至少使用5个短文中标有下划线的关键词语；3续写部分分为两段，每段的开头语已为你写好；4续写完成后，请用下划线标出你所使用的关键词语。Paragraph 1: Approaching the doorway, Jenny took a deep breath.

When she knocked at the door, she found the door was locked and her mother was not in. Tired and sad, she sat down in front of the house. “Where could my mother be？” she wondered, “was she still angry with me？”Again, the scene of the quarrel appeared in her mind. She remembered her rudeness to her mother. Realizing that all the_scolding_from_her_mother was due to the fact that her mother really cared a lot about her, she felt rather ashamed, and tears began to roll down her cheeks.Paragraph 2: A gentle touch on her hair called her mind back. She raised her head and saw the familiar_face of her mother. “Here you come! Ive been looking for you，” she said, tired and relieved. Jenny couldnt help throwing herself into her mothers arms. “Mum, Im so sorry and thank you for all you have done for me.” She expressed her sincere apology and great gratitude. Hearing this, her mother smiled patting her back gently.
