15．Whether they're project documents，trade journals，blogs，business books or ebooks，most of us read regularly as part of our jobs，and to develop our skills and knowledge．
But do you ever read what should be a useful document，yet fail to gain any helpful information from it？Or，re-read something several times to get a full understanding of the content？If so，look at the following strategies （策略） that will help you read more effectively．
●Think About What You Want to Know
Before you start reading anything，ask yourself why you're reading it．Are you reading with a purpose，or just for pleasure？What do you want to know after you've read it？Once you know your purpose，you can examine the resource （資源） to see whether it's going to help you．
Ask yourself whether the resource meets your needs，and try to work out if it will give you the right amount of knowledge．If you think that the resource isn't consummate，don't waste time reading it．
●Know How Deeply to Study the Material
Where you only need the shallowest knowledge of a subject，you can skim material．Here you read only chapter headings，introductions，and summaries．
If you need a moderate （中等的） level of information on a subject，then you can scan the text．This is when you read the chapter introductions and summaries in detail．You can then speed read the contents of the chapters，picking out and understanding key words and concepts．
Only when you need full knowledge of a subject is it worth studying the text in detail （細(xì)節(jié)）．Here it's best to skim the material first to get an overview of the subject．This gives you an understanding of its structure，into which you can then fit the detail gained from a full reading of the material．

44．Why should we know our purpose before reading？D
A．Because we can develop our skills and knowledge．
B．Because we can get a full understanding of the content．
C．Because we can avoid re-reading something several times．
D．Because we can check it out whether the material will be helpful．
45．What does the underlined word"consummate"in the 5th paragraph mean？C
A．Legal  B．Natural C．Perfect D．Formal
46．According to the depth to study the material，how many reading strategies are mentioned？B
A.2．
B.3．
C.4．
D.5

5．BERLIN （Reuters）-Germany's postal service has announced plans to explore improved service and help protect the environment by getting"fetch friends"-ordinary people traveling across cities-to deliver parcels on their way．
It is hoped that the move，which will be tested in the coming months，might lessen traffic in inner cities and reduce CO2 emissions（排放）．This should help DHL，a division of the German postal service，reach its target of improving the company's carbon efficiency by 30 percent before 2020．
"As the world's biggest logistics（物流） provider，we recognize a special responsibility to reduce the impact on the environment as much as possible，"said Frank Appel，Chief Executive Officer of Deutsche Post DHL，in a statement referring to a variety of measures being considered．
The"fetch friends"find out online about parcels that need delivering to people who live or work along the way that they are planning to travel through the city．They then select the ones that they want to take．
Codes（編碼） sent to their mobile phones tell the volunteers where to pick the packages up．Parcels can be taken part of the way or passed on to another volunteer but all volunteers need to have the right code on their mobile phone so the track and trace system can be updated．
Logistics companies will be responsible for looking after the operation to make sure that the privacy of post is respected．
It's hoped that this could be done using mobile phones but DHL says it recognizes that some security issues remain to be worked out．

67．According to the passage，the"fetch friend"programD．
