Answer 1

分析 本文作者主要分析了在科技迅猛发展的今天，仍然还存在贫困人口的原因（即在于人口数量的急剧增加）．

解答 Though great progress has∧made in science these years，there are still
many people living in poor conditions．They make theirlivesby collecting
and selling usedthing．Their children cannot go to school because they have
not enough money to send their children to there．Why∧you think so many
people still suffer from poverty now？The answer liesonthe population explosion．
A president of a developing country once said；"It isuswho are to blame for the
poverty because we used to'produce'child without limit．"Although this few words
sound simple enough，they have clear pointed out one of the causes of the population
explosion．
详解：
1．has后加been   考查语态   根据时间状语"these years"可知，此处应使用现在完成时；由于动词do与主语progress是被动关系，故此处应使用现在完成时态的被动语态；故在has后加been．
2．lives改为living　考查固定搭配    make one's living意为：谋生，故用living．
3．thing改为things　考查名词的单复数   此处指的是：一些用过的东西，故用复数名词things．
4．去掉to   考查介词   由于there是副词，其前不能再加介词；故去掉to．
5．Why后加 do　考查助动词    根据时间状语"now"可知，本句应使用一般现在时；由于此处用在特殊疑问词why之后，主语you之前，构成的是特殊疑问句；故用助动词do．
6．on改为in　固定搭配     lie in意为：在于…；故用in．
7．us改为we　考查强调句   本句符合强调句"It is/was+被强调部分+that/who+句子的其他成分"这一结构，强调的是句子的主语，故用we．
8．child改为children　考查固定词组    produce children生育子女，故用children．
9．this改为these　考查指示代词   此处用来修饰复数名词words，指的是这几个字，故用these．
10．clear改为clearly　考查副词    此处用来修饰动词词组point out，故用副词clearly．
