分词有现在分词(ing)和过去分词(ed)两大类，是英语学习中非常重要的一环，许多学生在阅读时读不懂的长难句大都有分词的影子，而在高级写作中，如果掌握了分词的正确用法，也会为你的写作增添光彩。其实，分词的主要功能是代替了定语从句和状语从句，使的句子更加简化，凝练。
通常来讲，无论是状语从句还是定语从句，如果里面的谓语是主动形式，则转化为现在分词 (ing)，谓语是被动形式则转化为过去分词(ed)，而现在分词主要分为doing/having done两种，过去分词主要分为done /having been done两种
L1：for the des criptions given by people who claimed to have seen the puma were extraordinarily similar. (given 作后置定语，修饰des cription，表示“人们提供的描述”)
The hunt for the puma began in a small village where a woman picking blackberries saw 'a large cat'. (picking 作后置定语，修饰woman，表示“正在采摘黑莓的女士”)
L2：Looking at his watch, he saw that it was one o'clock, (looking作状语，修饰主句中的动词saw，表示伴随状态)
Armed with a torch, the vicar went up into the clock tower to see what was going on. (Armed作状语，由于be armed with形式所以采用过去分词，在句中作状语，修饰went up，表示伴随)
L8： St. Bernard dogs have saved the lives of travellers crossing the dangerous Pass. (crossing 在这里作后置定语，修饰travellers，表示“穿越关隘的游客”)
L11：even if he has five hundred gold watches hidden in his suitcase.(hidden作后置定语，修饰)
L13：Not wanting to frighten the poor man, Mrs. Richards quickly hid in the small storeroom under the stairs. (wanting的否定形式在这里作目的状语)
L22：Then, squinting his eyes, he said: 'The light is dim. Read the letter to me'.(squinting作伴随状语)
L24: Dropping my suit, I dashed downstairs to tell George.(dropping作伴随状语，说明和dash这个动作同时发生，突出当时的恐惧之情)
关于分词的用法，新概念三册随处可见这样的例子，上面列举的句子也只是新三的皮毛而已，如果同学们对分词的用法感兴趣，或者想要把它牢牢掌握，可以找出新三中其他带有分词的句子逐一分析，相信一定会大有收获。
英文中的双重否定功能很多，很多同学认为双重否定有些啰嗦，表达的和肯定句是一样的，其实不然，双重否定句还有另外两个功能，即强调否定和委婉否定。
第9课中描述猫的吸引力，原句：Cats never fail to fascinate human beings.其实这里的双重否定never fail to 相当于英文中的always，不过更加突出强调了“总是”。比如我们表达对某道菜的喜爱，就可以利用这种方式：Sweet and Sour Pork never fail to fascinate human beings.
第26课中描述广告的吸引力，原句：No one can avoid being influenced by advertisements. 作者在这里想强调的是人人都会受到广告的影响。在我们平时写作时，当描述一片美丽景色时，也利用这个句型，比如：No one can avoid being tempted by the beauty of Shangri-la. 没有人能避免受到香格里拉美景的诱惑。
第43课中描述“常有的事”，原句：It is not uncommon to hear that a shipping company has made a claim for cost of salvaging a sunken ship. 这里的not uncommon便是指的“常有的事”，类似的表达还有not illegal、 not unavailable，not unusual等等。
不定冠词“a”用来表示可数名词的单数形式，用于辅音音素前，an用于元音音素前。
