    1．Dark matter gives out no light and only because of its gravity effect on visible matter ________ see its existence．（　　）
    A．does everyoneB．everyone doesC．does nobodyD．nobody does

    分析 暗物质不发光，只是因为他对于发光物体的重力效应我们每个人才能看到它的存在．

    解答 答案：A．
    本句考查only加介词短语位于句首后面的主句用部分倒装结构的用法．because of its gravity effect on visible matter 为一介词短语做原因状语，所以后面的句子用部分倒装，可排除B和D，结合句意，应该是每个人都能看到这一暗物质的存在；故选A．

    点评 对于倒装句型要熟悉这一基本结构，即Only+状语或者状语从句+部分倒装的主句．

    What is a fair wage? 1. These are some of the questions the United Nations International Labour Organisation(ILO) has recently investigated.

    With a global population of over seven billion, is it actually possible to measure an average amount?_ 2._ Using the total wage bill from over seventy countries, they have multiplied the amounts by the number of earners in each country. The economists then tallied up the results and divided them by the total number across the world The result was a world average wage equivalent to $1,490 a month. _3._

    This figure might seem very high because they calculated the amount using purchasing power parity dollars, which takes into account the fact that it is cheaper to live in some countries than others. _4._

    Calculating an average sum like this might not be a completely fair representation, but these figures do help us to understand how the world is developing, both economically, in the quality of life people are experiencing and their standard of living.

    But the result shows that the average wage is still relatively low and there remains a huge difference in levels of affluence around the world. _5._ Is this fair? For many, pay equality still seems very far out of reach.

    A. The ILO has now tried to work out the sums.

    B. The ILO used statistics from over 70 different countries

    C. Why aren't more people in the world offered pay equality?

    D. That is approximately $75 a day for a 20-day working month.

    E. Some people live on just two dollars a day, while others are earning more than a million dollars a year.

    F. When someone works for themselves, what are they called?

    G. The data also did not include the huge number of people who appear in poverty statistics or who are self-employed.
