题目内容

3.It rained heavily in the south,causing (cause) serious flooding in several provinces.

分析 南方雨下得很大,结果在几个省引起了洪水.

解答 答案是causing.本题考查现在分词做结果状语.根据句子结构判断,句中已经有了谓语动词rained,所以cause必须用非谓语的形式;根据语境判断大雨导致的结果是几个省发洪水,句中需要的是结果状语;非谓语动词中动词不定式和动词-ing形式都可以做结果状语,动词不定式表示"出乎预料的、令人沮丧的结果";动词-ing形式表示"自然而然的结果",句中显然是"自然而然的结果",所以用现在分词causing.

点评 本题是要求用所给词的适当形式填空,解题时首先考虑句中需要的词性;其次,如果是谓语动词关注时态、语态和数的变化;如果是非谓语动词要联系非谓语的基本用法判断非谓语的形式;如果是名词关注单复数.

14.A.Means of e-waste recycling
    B.How e-waste coming into being
    C.The benefit of e-waste recycling
    D.The technologies of e-waste recycling
    E.The importance of recycling e-waste
    F.Modern technology bringing convenience and e-waste
61.FModern technology does bring us much convenience,from Wi-Fi (无线网络) enabled cell phones and ever-smaller laptop computers that make our entire lives easy to energy-efficient washers that use half the power and time to complete their tasks. However,these new toys and equipment finally become electronic waste ( e-waste) once they are out of use.
62.B  
 E-waste includes everything from empty printer ink containers to broken refrigerators. As people buy new items to replace aging electronics or make updates,more electronic waste comes into being. In some cases,such as 2009's switch from analog (模糊) to digital television broadcasting in the United States,changes in technology are so great that old equipment may not even work at all with new systems.
63.EThere are many reasons why it is important to recycle electronic waste. Much of the material used to construct electronics,including metal and plastic parts,can be recycled into new items at a discount of the cost and energy use needed to create things from new raw materials. Additionally,many electronics contain poisonous substances that are harmful to the environment and could be deadly if they go into an area's groundwater. When  properly recycled,they can be reused and will not do harm to the environment. Because of the environment concerns,many areas require by law that electronic waste be properly recycled.
64.AThe availability of e-waste recycling programs varies from place to place. In some areas,collections are held once or twice a year as a means of dealing with e-waste as well as used engine oil or other waste that is harmful to the environment,There are also some good alternatives to recycling your e-waste. Any items that are in working condition can be given to friends or donated to charities like Goodwill or The Salivation Army,who rely heavily on donations. Freecycling,or passing on your unwanted items to those in need of them,is also a means of finding new homes for used items.
65.C E-waste recycling helps protect the environment by reducing the amount of poisonous materials placed in landfills (废物填埋场) and saving recyclable parts to save energy and other resources. Recycling is a way of life. Once we have made that choice to carry out all the steps of recycling in our daily lives,and stick to that choice every single day,recycling becomes second nature to us.
11.I could clearly remember my first day in the 5th grade.I was a new student then,having transferred(转学) to a local school for boys.Life was really difficult for my parents having transferred me to a school with a higher schooling fee.As much as we could,all unnecessary expenses (费用) were dispensed with(免除).
At school,we were required to wear a white shirt with the school's sign on its upper left pocket that could be bought in the school shops.And at the top of this pocket a name tag(标签) should be worn to best prove each student.This tag was sold at the shops too.To cut added expenses,Mom decided to make the tag herself.
"This would do,"she said,pushing the tag through the button at the top of the pocket."OK Mom".I was not ready to wear it.I thought it was different and irregular.At school,some boys made fun of me because of the tag."Your helper sure did an ugly job".And another remarked"How strange it is!At least it caught our attention".I knew it.At first,I tried to cover it and ignored it.But at last I knew that it didn't matter if it was different from others who wore the machine-made tags.
I realized it should not stop me from doing my best in spite of our differences in culture of economic situation (经济状况).What is true is that Mom spent much time making it possible to give the best to me.I should be proud of it.And I did; I wore this Mom-made tag for the rest of the school year.
