马致远故居

    马致远故居位于京西门头沟区王平镇“王平古道”的韭园村,村内的西落坡村有一处元代古民居,当地村民们世代相传,说这里就是马致远故居。马致远故居坐西朝东,是一座静谧的大四合院。故居门前有【甲】,门前的影背墙上写着“马致远故居”,并有马致远的生平介绍。马致远的名曲《天净沙·秋思》中的佳句广为人知,实际上,他故居门前的景物也和《天净沙·秋思》的意境颇为相似。绕过影壁跨过东房的大门就来到院子里。院子很大,西北东南四面都有房间,每边为三五间。

    在我国文学史上,元代的戏剧可以说是灿烂辉煌的。很多著名的大戏剧家都是大都(北京)人,如关汉卿、王实甫、马致远。他们的剧本经常在大都西城砖塔胡同里的勾阑、瓦舍(剧场)中演出,有时他们还亲自粉墨登场。元代的很多经典剧目,如关汉卿的《窦娥冤》《望江亭》,王实甫的《西厢记》,马致远的《汉宫秋》《青衫泪》《荐福碑》等,久演不衰。北京可以说是我国戏剧的发祥地之一。

    据《中国文学史》和其它一些资料记载,马致远(1250—1324),字千里,号东篱,大都人,原籍河北省东光县马祠堂村,死后葬于祖茔。马致远是我国元代著名大戏剧家,学识(yuān bó)      ,有“姓名香贯满梨园”之称,是当时文学组织“贞元书会”的主要成员,为“元曲四大家”之一。他还被尊为“曲状元”,在文学史上有极高的声誉。马致远因不满官府的腐败,后便隐居山林,过着“酒中仙、尘外客、林中友、曲中游”的自由(ān shì)     的生活。

    马致远隐居的山林在何处,并没有确凿记载,但在韭园村的西落坡村发现有马致远故居。另外,马致远的一些曲子也可证明他曾经在这里居住过。如《元曲三百首》中的《清江引·野兴》写道:“西村日长人事少,一个新蝉噪。恰待葵花开,又早蜂儿闹,高枕上梦随蝶去了。”这西村应该就是西落坡村,是相对东落坡村而言的。马致远故居已被文物部门确定,修复后将会定期对外开放。

阅读下面短文,从短文后各题的A,B,C,D四个选项中,选出适合填入对应空白处的最佳选项。

    When I was 16, I wrote a list of things I wanted to do in my lifetime. Some things were easy, some difficult and some almost 1. One of the things on the list was to do a 2.

    Two years ago I spent three months travelling with a friend and it was a great experience. One of the most 3 things we saw was Iguassu Falls. The day after we visited the waterfalls we were 4 in a hotel in Brazil, playing games when my friend 5 noticed an advertisement on the wall 6 “Skydive over Iguassu Falls today!”. I realized it was time to realize my 7. Today would be the day that we would jump out of a(n) 8.

    That afternoon we were 9 and taken to the Skydive Centre. We put on our harnesses(跳伞装备)and helmets, were given some 10 and then took off into the air. My heart started to beat very fast and I felt very 11.

    Luckily, I was 12 to an instructor so I didn't have to worry about anything; I just had to 13 myself. He asked me if I was ready to fall from the plane but 14 I had enough time to 15, we fell to the ground at 400 km an hour! After about 40 seconds of 16, the parachute opened and everything slowed down. We 17 peacefully towards the earth, leaving the 18 behind us.

    This was definitely one of the scariest but most exciting 19 of my life. I would do another skydive if I had the20. I think that everyone should do something that scares them once in a while!
