1如何区分May be,maybe?
2什么叫现在分词,一般用在什么时候,能否举几个例子?
也可以出几道题,填空题之类的
讲解的越清楚越好
[不好意思,打错了,是过去分词】如果可以的话,请今晚给我答案,
1、may be和maybe一分一合,但它们的含义和用法却截然不同.  maybe是副词,意思是“也许、可能”,在句中作状语,相当于perhaps,常位于句首.  Maybe she’ll come this afternoon.她可能今天下午来.  Maybe you put the letter in your pockets.大概你把信放在衣袋里了.  在may be中,may是情态动词,be是动词原形,两者构成完整的谓语形式,与主语形成系表结构,意为“也许是、可能是”.  I can’t find my watch.It may be in your pocket.  我找不到我的手表了,它可能在你的口袋里.  He may be a soldier.他可能是军人.  maybe和may be可相互转换.  He may be in the office.  = Maybe he is in the office.他或许在办公室.  You may be right.  = Maybe you are right.你或许是对的
2、现在分词(Present Participle)(又称-ing形式、现在进行式) ,是分词的一种,分词又分为现在分词和过去分词,它们都是非限定动词,即在句子里面不能单独充当谓语,但能充当其它的一些成分(定语,表语,补语和状语),并且它们具有动词的性质,所以又是类动词的一种.一般式doing 一般被动式being done 完成式havingdone 完成被动式having been done 所有否定式都是在-ing前面加not 包括独立主格形式
1.现在分词作定语,表示正在进行的或主动的动作.也可以说明被修饰词的性质和特征,此时可换成相应的定语从句.例如:  ① There was a terrible noise following the sudden burst of light.  ② He saw a flying bird and raised his bow.  ③ I was satisfied with the exciting speech.  2.现在分词作状语时,可作时间、条件、结果、原因和伴随状语,表示正在进行的或主动的动作.此时分词的逻辑主语就是主句的主语,因此要注意人称、时态和语态的一致性.例如:  ① The visiting minister expressed his satisfaction with the talks,adding that he had enjoyed his stay here.  ② European football is played in more than 80 countries,making it the most popular sport in the world.  ③Seeing from the top of the hill,we can find that the city looks more beautiful.  3.现在分词作补足语,表示正在进行的或主动的动作.例如:  ① Soon they could see the steam rising from the wet clothes.  ② The missing boys were last seen playing near the river.  4.现在分词的独立主格结构作状语.例如:  ① With his lips still trembling,he couldn't say a word.  ②“ Mama!” he cried suddenly,tears rolling down his cheeks.“妈妈!”他突然哭着喊,泪水从他的脸上流下来.(这里需要用现在分词的独立主格结构 tears rolling down his cheeks 作状语.)   ③ Weather permitting,we'll go to the Great wall.如果天气允许的话,我们就去长城.(这里需要用现在分词的独立主格结构 Weather permitting 作状语.)
再问: 呵呵,谢谢。由于我打错字了,能帮解释一下,什么叫过去分词吗/
再答: 规则动词的过去分词一般是由动词加ed构成(具体规则见后),不规则动词的过去分词见不规则动词表。 过去分词则属于类动词: 1. 及物动词的过去分词作表语,与句子的主语是被动关系,表示主语的状态,不但表示被动,还表示已完成了. The cup is broken. 茶杯破了. 2. 不及物动词的过去分词作表语,与句子的主语是主动关系,表示主语的状态,只表示动作的完成. He is retired. 他已退休. 3. 有些过去分词作表语时,构成的谓语很接近被动结构. (1) The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的.(是被动语态,表示动作)   (2) The library is now closed. 图书馆关门了.(过去分词作表语) (3)We must adapt our thinking to the changed conditions. 我们必须使我们的思想适应改变了的情况. (4)The concert given by their friends was a success.他们朋友举行的音乐会大为成功.
