Boxes can usually serve as new storage containers and houses for pets.And clothing? Imagine taking old clothes and turning them into hats or bags.【解题导语】本文主要讲述了一位德国艺术家利用垃圾创造艺术作品的故事，并以此鼓励读者行动起来，为环保出一分力。

Unit 4SharingSection ⅡWarming Up & Reading—Language Points课时作业Ⅰ.单句语法填空1．Hearing the yell of the hunter, the bear fled along the muddy (mud) path.2．The weekly (week) meeting usually lasts about two hours，which makes us annoyed.3．Many students who can speak English fluently often act as interpreters (interpret) for foreign visitors.4．We're trying to come to an arrangement (arrange) about who should pay the fees.5．The rectangular (rectangle) building in the picture is still under construction.6．The government intends to make adjustments (adjust) to the pension of the retired people.7．I was reflecting on what I should do next when the noise of an explosion almost scared me to death.8．The drunk driver fled from the scene with his car abandoned (abandon)．9．We can recommend any of our friends to participate in your project!10．—He promised to write to me，but I haven't heard from him so far.—Well，something unexpected might have happened to him.Ⅱ.单句改错1．The children were running to move the bag of rice while they heard the sound of a motorbike. while→when2．I was about to leave which the phone rang. which→when3．With prices went up so fast，we can't afford luxuries. went→going4．He has five children，two of them are abroad. them→whom5．The man hid himself behind a big tree，from there he saw a lion come.there→where Ⅲ.阅读理解V olunteers abroad always return home feeling like they made a really worthy contribution to the area they visit.It's quite right because any volunteer organization will put your skills to work in the most valuable way possible.V olunteer teaching in Africa is one of the areas where help is always wanted.Even if you don't have teaching qualifications (资格) right now，it doesn't mean you won't be welcome.Many volunteer teaching assistants are people in the early years of their studies.Others have no long-term teaching plans but a willingness to take on new challenges and help wherever they can.It's not just classroom work either.For example，recent storms in Livingstone in Zambia took the roof off the local school.V olunteer teaching assistants rolled up their sleeves and helped put it back on again.Teaching in Africa is more than sitting in classrooms with young children.If sports education is your thing，there are opportunities for you to help teach your skills with notable programs in Zanzibar，Mozambique，South Africa and Zambia.In these same areas there is equal need for education of adults，not just for their personal development but also in many other ways.If you think it's all work and no play，there will be plenty of time for you to have your own adventures in this beautiful country.There's white-water rafting on the Zambezi，surfing off the East African coast.If peaceful and quiet life interests you，there are famous South African vineyards (葡萄园) and the top restaurants of the Cape Town.Whatever your skill is，volunteer organizations will find a place for you where you can make the most difference.Whatever you give volunteer teaching in Africa for a couple of weeks or a couple of months，you will have great influence on the people you meet.You really can help change people's lives.【解题导语】你想到非洲志愿支教吗？欢迎你来非洲支教，总有一份工作适合你。

2．—Tom seems to be a bit ner v ous.—True. After all, it is the first time that he________ (appear) on the stage.答案与解析has appeared在句型“It/This is the first/second/third/... time (that) sb. have/has done sth.”中，从句一般用现在完成时。
3．Susan didn't come to the party because she w as ________ (occupy) w ith her report.答案与解析occupied根据Susan didn't come to the party可知，她忙于(w as occupied w ith)她的报告，填occupied。

5．The door w on't ________ (lock). Something has gone w rong w ith it.答案与解析lock句意：门锁不上，出毛病了。
lock表主语的特性时，为不及物动词，无被动语态，常与w on't连用。
6．If w e don't hurry up, e v erything w ill ________ (eat) by the time w e get to the party.答案与解析ha v e been eaten句意：如果你不快点，当我们到了晚会一切都会被吃光的。
根据by the time时间状语从句的一般现在时态可判断出主句应用将来完成时，且eat与e v erything为被动关系，故填ha v e been eaten。
7．They are li v ing in the company for the moment because their o w n house ________ (decorate)．答案与解析is being decorated句意：他们暂住公司因为他们自己的房子正在被装修。
根据主句的现在进行时态可判断从句用现在进行时，且decorate与其逻辑主语their o w n house为被动关系，故用现在进行时的被动语态。
8．The room ________ (measure) 10 metres across is large enough for a single man ________ (li v e) in.答案与解析measuring; to li v e第一空，考查动词的-ing形式作定语，相当于w hich measures；第二空，不定式作结果状语，填to li v e。

表示“……的能力”，要用不定式作后置定语来修饰the ability。
10．The w itnesses ________ (question) by the police just no w ga v e v ery different descriptions of the fight.答案与解析questioned句意：刚才警察询问的目击者对这次打架给出了完全不同的描述。
由于the w itnesses和question是逻辑上的动宾关系，同时在句中有表示过去的时间状语just no w，故用动词的-ed形式作后置定语表示被动和完成。
故填questioned。
11．—What's the matter w ith Tim?—Oh, Tim's cellphone w as left in a taxi accidentally, ne v er ________ (find) again.答案与解析to be found句意：——蒂姆怎么了？——哦，他的手机不小心落在出租车上了，永远也找不到了。
分析句子结构可知，空处应用不定式作状语，表示意想不到的或事与愿违的结果。
