29.B

30.B文章第二段倒数第二句和最后一句谈到了批评家们对现代生活方式的忧虑。法国人在追求物质生活的同时，也失去了很多东西。所以答案应是B项。

31.A

33.C

34.B解析：玛丽同她的兄弟一起为许多博物馆、科学家等提供了整理好的化石标本。

72.Bshould在此处表示“竟然”。

74.C

75.Dregularly“有规律地”；rarely“极少，很少”；frequently“经常地”；little“几乎没有，几乎不”。D项是正确的。句意为：“他很少学习，可每次考试都过。”如果将little放在动词后面，这句话就对了：Hestudiedlittle．“他几乎不学习”。

76.A

78.C解析：本句是强调句型。
