三峡

       自三峡七百里中,两岸连山,略无阙处。重岩叠嶂,隐天蔽日,自非亭午夜分,不见曦月。

       至于夏水襄陵,沿溯阻绝。或王命急宣,有时朝发白帝,暮到江陵,其间千二百里,虽乘奔御风,不以疾也。

       春冬之时,则素湍绿潭,回清倒影,绝多生怪柏,悬泉瀑布,飞漱其间,清荣峻茂,良多趣味。

       每至晴初霜旦,林寒涧肃,常有高猿长啸,属引凄异,空谷传响.哀转久绝。故渔者歌曰:“巴东三峡巫峡长,猿鸣三声泪沾裳。”

1、解释下列划线的词语。

      ①略无处(                          )

      ②亭午夜分(                          )

      ③王命急宣(                          )

      ④乘奔御风,不以疾也(                           )

2、“素湍绿潭,回清倒影”句中描绘色彩的词语有                      、                        、清;本句中前后两个分句有内在的对应关系,以“回清”写出                         的动态,以“倒影”写出                      的静态,一动一静相映成趣。

3、文中画横线的句子使你联想到了哪个古人?哪两句古诗?

                                                                                                                                                                                                            4、按要求填写相关语句。

     (1)表现群山高峻的句子:                                                                                                    

     (2)表现水流急速的两个四字短语:                                                                                                  

     (3)表现山河秀丽的两个四字短语:                                                                                                 

     (4)表现秋境的凄清、令读者恍若身在其境的两个四字短语:

                                                                                                                                                            

5、用现代汉语写出下面句子的意思。

     (1)自非亭午夜分,不见曦月。

                                                                                                                                                

     (2)或王命急宣,有时朝发白帝,暮到江陵。

                                                                                                                                               

     (3)虽乘奔御风,不以疾也。 

                                                                                                                                              

     (4)巴东三峡巫峡长,猿鸣三声泪沾裳。

                                                                                                                                               

 6、文章末尾引用渔者的歌词,其作用是什么?

     Having lived in California until 1970,my family has felt a number of earthquakes.We have been

fortunate,however,to have suffered no bodily harm or property damage.

     There is a website that lists all California earthquakes recorded from 1769 to the present.The site lists

the dates and times as well as the magnitude (震级) and the exact location of any quake that measured

more than 6.0.There are only a few quakes that stand out in my memory and,luckily,none is shown in the

website.So,my personal experience with earthquakes might be considered insignificant.

     There are three earthquakes that are difficult to forget.The first one was in 1955 and our oldest

daughter was walking with me in our backyard in Redwood City in California.As the shaking became

stronger I held her to me with one arm as I held on to one of our fruit trees with the other.All three of us

(my daughter,I and the tree) shook for two or three minutes that to us felt like hours.

     The second one was in 1963.Our entire family was visiting Disneyland in Southern California.The earth started to shake just as we were beginning to walk from our hotel toward the_famous_landmark.

My third experience with an earthquake was a lonely one in California.It was in my sixties and I was alone in an old church.As the building started to shake,I quickly headed for the door to go outside.I remember I said a little prayer-something like,"Help me get out of here in time,Dear Heavenly Father".Minutes later,I was safe outside.
