這個(gè)句子的確有點(diǎn)復(fù)雜，現(xiàn)分析如下：
    1. 句中的 however, with the assistance of her five daughters 為插入成分，可以先撇開(kāi)不看。于是原句可簡(jiǎn)化如下：Not all that Mr. Bennet could ask on the subject was sufficient to draw from her husband any satisfactory description of Mr. Bingley.
    2. 在上面這個(gè)簡(jiǎn)化的句子中，由于動(dòng)詞 draw 的賓語(yǔ) any satisfactory description of Mr. Bingley 過(guò)長(zhǎng)，被后置了，其實(shí)此句的正常語(yǔ)序是這樣的：Not all that Mrs. Bennet could ask on the subject was sufficient to draw any satisfactory description of Mr. Bingley from her husband.
    3. 經(jīng)過(guò)上面的分析可以看出：原句的主語(yǔ)是 not all，其后的 that Mrs. Bennet could ask on the subject 為修飾 all 的定語(yǔ)從句。這個(gè)再簡(jiǎn)化一下，就是這樣：Not all that…was sufficient to draw sth from sth.
