请解释下6,7题,
第6题UN是指的联合国,A UN report says that the world population will 7 six billion by the end of the 20th century．先不看第7题,句子的前半部分说的是,一份来自联合国的报告称.,第6题的四个选项分别为USA,UN,PRC,PLA,他们代表的意思分别是,美国,United Nations 联合国,People Republic of China 中国,People Liberation Army 中国人民解放军.自然,来自联合国的报告才最具有权威性,也最为合理.答案为B.
第7题,现在我们把答案带入原句,句子翻译为：一份来自联合国的报告称,截至20世纪末,全球人口将超过70亿人.选项A,past 是指的时间上的超过,多出,例如：10 past 9,9点10分.而,数量上的超过,在这里则使用B,即pass.再者,这里不涉及时态和第三人称,因此不需要变为过去式passed或者passes.故答案为B,pass.
以上就是我的解释,希望能够帮到楼主~有不明白的还可以再问我~
再问： 请问第9题呢
再答： 你第8题明白的吧？那句子的意思就是，这只是在达到50亿人口10年以后。10年过去了，这个句子本身是一般时态，但对于已经过去的，已经达到的而言，达到的动作发生在过去，所以就是过去时，自然是用过去式了，reached。不懂接着问，没事儿~~
