55. C。本题考查作状语的独立分词结构。

56. C。这题有难度。本题是考查独立主格结构，这里是由“with+名词+不定式”构成的。因为I同时充当to do的逻辑主语，因而这里的不定式不需要被动to be done，而要用主动to do。

57. C。首先是find somebody doing，然后分词chatting充当伴随状语，修饰sit。

58. C。分词作状语，表示伴随状况。

59. B。本题考查作状语的独立分词结构。逻辑主语others与分词是被动关系，所以该用过去分词built。

60. B。这题有难度。首先是carrying现在分词作状语，修饰answered，表示伴随状况。其次，过去完成进行时had been reading表示“刚刚结束的动作”。有兴趣的读者可以参看“中级语法”中的完成进行时态内容，其中对这个句子有详细解释。

61. C。本题考查作状语的独立分词结构。其中seated是表示被动，由seat somebody得来，这与汉语思维表达习惯不同，值得注意。

62. B。答案来自于make up one's mind搭配。

63. A。这里是三个并列的过去动作，不是分词。

64. B。考查分词的主动与被动。因为delegates与assemble是主动关系，而problems与discuss是被动关系，所以分别用现在分词和过去分词。

65. D。这题有些难度。其实这里being是一个动名词，不是现在分词。读者可参看第7章有关动名词与现在分词的区别。

66. C。letters与write是被动关系，所以用过去分词。

67. B。考查compare...with...搭配。

68. A。这里spawn是谓语。其后都是分词或从句。定语从句that drift about修饰larvae。

69. A。考查分词构成的复合形容词。这里是“副词+过去分词”构成形容词，故只有A正确。

70. B，改为written。

71. A，改为Written。

72. B，改为employing。
