1. 答案：B.

【解析】我們發(fā)現(xiàn)有關鍵詞"Born"與age、five years old相呼應。再看空格的前兩句內(nèi)容提到They are all five years old. Why are they all the same age? 結(jié)合常理我們能夠得到他們應該是同時出生的。分析五個選項，排除不符合前后文意思內(nèi)容的選項。再通過后文說They are septuplets!(七胞胎)第二個選項明顯符合先后文的因果關系，故選B。

2. 答案:E.

【解析】先看單詞，look after復現(xiàn)?？纯盏那昂?，前文說同時照顧七個寶寶是個艱辛的工作，后文說起初有很多人幫助他們。前后邏輯是相反的，所以中間應該有轉(zhuǎn)折。再看選項，把各個選項實在帶入只有E符合前后行文順序其它的內(nèi)容均與該空無關，故選E。

3. 答案：A.

【解析】首先注意關鍵詞they 的指代，前文說到他們每天需要大量的尿布，而把所有選項帶入后發(fā)現(xiàn)只有A選項與原文空格位置邏輯順序相符。故選A。其他選項與前文所描述內(nèi)容不能有效聯(lián)系，所以不選。

4. 答案：C.

【解析】關鍵詞復現(xiàn)：Bobbi和關鍵詞替換原文中的teach與選項中的teacher,從邏輯看，帶入C，去年Bobbi 是Mikayla的老師，與下文現(xiàn)在她是所有孩子的老師成順承關系。同時注意空格后一句的內(nèi)容。把選項C帶入前后文所描述的內(nèi)容一致。故選C。其它選項與本題前后內(nèi)容描述不一致邏輯不一致，故不選。
