【解析】本篇主要講述了關(guān)于人口增加的問(wèn)題，地球上人口的不斷增多，對(duì)我們的生活，環(huán)境，地球都造成了影響；隨著人口問(wèn)題不斷發(fā)展，我們地球資源不斷消耗，有科學(xué)家提出開發(fā)金星。

【1】考查冠詞。句子成分完整，賓語(yǔ)problem是單數(shù)，所以前面要加冠詞，“extremely”是元音開頭，所以應(yīng)該填an。

【2】考查將來(lái)完成時(shí) 由“By the middle of the 21th.”可知，用完成時(shí)態(tài)，由因?yàn)槭前l(fā)生在將來(lái)的，所以應(yīng)用將來(lái)完成時(shí)，故填wil have used。

【3】考查名詞單復(fù)數(shù)。some后加名詞復(fù)數(shù)形式；所以way后要加“s”，故填ways。

【4】考查固定句式。make it +形容詞+to do sth.,使做某事怎么樣。所以填it。

【5】考查to do不定式。be able to do sth. 能夠做某事；故填to support。

【6】考查固定搭配。a/the solution to the problem解決問(wèn)題的辦法。故填to。

【7】考查表語(yǔ)從語(yǔ)句。is后面是表語(yǔ)從句，表語(yǔ)從句中部缺少成分。故填that。

【8】考查副詞。副詞修飾形容詞，totally修飾后面的possible。故填totally。

【9】 考查時(shí)間狀語(yǔ)從句 根據(jù)句子意思，應(yīng)該是在他的想法變成現(xiàn)實(shí)之前，人們還有很長(zhǎng)一段時(shí)間要走；所以填before。

【10】考查比較級(jí)。后面有than，所以應(yīng)該是比較級(jí)，hot的比較級(jí)是hotter。
