Ⅰ　阅读理解
Plastic sludge (污泥) and garbage is a disaster for the world's oceans. 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 world's 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.

1．What can we learn from the passage?
A．There's all island full of plastic rubbish in the Pacific.
B．The bad effect of plastic pollution can't be seen by eyes.
C．The United States is the least plastic polluters.
D．The 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。
2．What does the underlined word “they” refer to in Paragraph 3?
A．Pollutants like heavy metals and medicines.
B．The plastic particles.
C．Seafood.
D．Fatty 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。
3．What can be inferred from the last paragraph?
A．All Asian countries have the most serious problem of plastic pollution.
B．The plastic problem hasn't attracted the world's attention.
C．Andersen is not satisfied with what has been done to solve the plastic problem.
D．People 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。
4．Which may be the title of the passage?
A．Plastic pollution in the World
B．Plastic pollution—Oceans' Disaster
C．Ways to solve the problem of plastic pollution to oceans
D．Plastic 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。
Ⅱ　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 couldn't 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 middle－aged 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 don't have money on me ... ” she replied.
“That's nothing. I'll 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 mother's 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.

[精彩范文]
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! I've been looking for you，” she said, tired and relieved. Jenny couldn't help throwing herself into her mother's arms. “Mum, I'm 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.
