    Many textbooks are not written in the kind of English that we speak every day. In fact,

sometimes the reading is so difficult that it almost seems like a foreign language. In a

way, it is the language of science. You should not expect to be able to read a difficult

science passage the same way you read an interesting story; you should not expect to read

it easily and all at once. Instead, you may have to read it several times through, catching

on the meaning of difficult words, going back over difficult sentences, and finally putting

the whole thing together. Do not be discourages if the whole passage don't make sense to

you at first. You need to pick it apart patiently until you can understand it.

    These are the steps to follow when you are reading something difficult: 

    ☆1. Start to read normally until you run into a sentence that doesn't make sense to 

         you. 

    ☆2. When a sentence doesn't make sense, go back and read it again more slowly. 

    ☆3. Look for any word you don't know in the sentence. Try to understand their meanings

         using word parts and context clues(上下文线索). If necessary, look them up in the

         dictionary. 

    ☆4. Look at the next few sentences to see if they explain more about the sentence you

         are working on. Do not read very much farther ahead until you understand what is

         being said. 

    ☆5. Finally, read the sentence again. Try to put it into simpler words. 

    ☆6. Read through the passage once. Try to understand all the hard parts well. Then

           read the whole passage once more at a usual speed. This helps you to put all

           ides together. The stops sound a lot harder than they are. It is really just the

           normal way good readers understand anything that is difficult to read. After you

           have done the best you can this way, you should always feel free to ask for help

           from your teacher, if you have one.

根据经济普查资料初步测算，我国2004年GDP现价总量中，第一产业增加值为 20956亿元；第二产业增加值为73904亿元，其中，工业增加值65210亿元，建筑业增加值8694亿元；第三产业增加值为65018亿元，其中，运输邮电业增加值12148亿元，批发零售贸易餐饮业增加值15250亿元。

与2004年全国GDP年快报核算数相比，按经济普查资料计算的GDP总量增加了 23002亿元，提高了16.8%。其中，第一产业因不在这次普查范围内，数据变化不大，重新核算后增加了188亿元；第二产业增加值增加517亿元，提高了2.1%；第三产业增加值增加21297亿元，提高了48.7%。

在GDP总量多出的2.3万亿元中，有93%是第三产业引起的。造成第三产业增加值增加较多的原因，主要在于资料来源的增加。经济普查覆盖了第二三产业所有的法人单位、产业活动单位和个体经营户，大大补充了以往常规统计中难以准确全面反映的私营、个体服务业资料以及大量的新兴服务业资源，如计算机服务业、软件业、互联网信息服务和卫生传输服务业、娱乐业、租赁和商务服务业、家政服务业等。通过经济普查，进一步查清并补上了常规统计中第三产业漏统的部分。

2004年GDP重新核算后，与年快报数相比，第一产业、第二产业的比重有所下降，第三产业比重大幅度上升。第一产业比重由原来的15.2%下降到13.1%，下降了 2.1个百分点；第二产业比重由原来的52.9%下降到46.2%，下降了6.7个百分点；第三产业比重由原来的31.9%上升到40.7%，上升了8.8个百分点。重新核算后，我们可以看出，我国的服务业在经济整体中的份量不像原来估计的那么低，它对我国经济增长的拉动功不可没。然而，我们也要清醒地看到，虽然目前的三次产业结构比原来核算的要合理得多，但第三产业比重偏低的矛盾依然存在。

第三产业的增加值增多，下面说法不正确的是（）

A．主要是普查的资源来源比以前大大增加

B．主要是第三产业的发展速度较以前有很大程度的提高

C．主查这次普查更进一步地摸清了第三产业漏统的部分

D．主要是这次普查大大补充了以往常规统计中难以准确全面反映的私营、个体服务业资料以及大量的新兴服务业资料
