最伟大的爱

  (甲文)①上学的路上,有一条必经的小河。那年初春的一个早晨,当我匆匆忙忙赶往学校时,河上的冰还没融化,我三步并作两步冲上冰面。刚刚走到河中央,“扑哧”一声,一处冰面塌落了,我的两条腿踏进了冷彻骨髓的河水里。

  ②我穿着湿透的棉裤坐在教室里,全身仿佛都麻木了,我沉默地挺着,脸和唇都变成了青紫色。中午回到家,母亲很惊讶,却什么也没问,只是让我围着被褥坐在烧得热热的炕头上暖和。她蹲在火炉前为我烘烤棉裤。炉火灼灼,不时爆出些响声来,而母亲却始终一言不发。当母亲把烘干的棉裤交给我时,眼圈有些红肿。

  ③日子一天天过去,高考迫在眉睫。有一夜下了暴雨,清早上学来到那条河边。突然我发觉有什么人早在暴涨的河水里砌了一些大石头。那石头一块块稳稳地立在水里,石面高出了水面数厘米,远远看去就像一座简陋的石桥。我踏石而过的时候,心里淌过一股莫名的感激。那天晚上回到家,我无意中看到母亲手上缠着白纱布,血透出来,湿了一片,惊问她为什么受伤,母亲淡淡地答道:“不小心碰的。”站在一边的妹妹抢着告诉我:“妈妈的手是搬石头砸伤的。”“妈搬石头干什么?”我不解地追问。“搬石头搭桥呀!”那瞬间,我的心轰响着,久久说不出话来。

  ④那年九月,我踏过“母亲桥”去远方上大学。独在异乡,仍是母亲用无言的关注帮我度过每一次的疲惫和寂寞。渐渐地,我知道,是母亲用青春搭起我的生命之桥,用希望和奉献搭起我的通向成功和幸福之桥。如今,河上的“母亲桥”已经为风雨侵蚀残损,而在我的心灵中,“母亲桥”却永远踏不断

  (乙文)①父母的爱是天地间最伟大的爱。一个孩子,自从呱呱坠地,父母就开始爱他,鞠之育之,不辞劬(qú)劳(生养他,教育他,不辞劳苦)。稍长,令之就学,督之课之,惟恐不逮(督促他,惟恐达不到目的)。及其成人,男有室,女有归,虽云大事已毕,父母之爱固未尝稍杀(不曾有丝毫的松懈或减少)。父母的爱没有终期,而且无时或弛(没有一时松弛过)。父母的爱也没有差别,看着自己的孩子牙牙学语,无论是伶牙俐齿或笨嘴糊腮,都觉得可爱。眉清目秀的可爱,浓眉大眼的也可爱;天真活泼的可爱,调皮捣蛋的也可爱;聪颖的可爱,笨拙的也可爱;像阶前的芝兰玉树固然可爱,癞痢头儿子也未尝不可爱,只要是自己生的……

  ②父母的爱是天生的,是自然的……是无条件的施与而不望报。父母子女之间的这一笔账是无从算起的。父母的鞠育之恩,子女想报也报不完

1、甲文所记叙的中心事件是______,这正是乙文中心句______的具体表现;从表达方式看,甲文以_______为主,乙文以_______为主。

3、甲文第③段中主人公产生“莫名的感激”之情的原因是______________。

4、联系原文回答:“母亲桥”是一座什么样的桥?

President Barack Obama has apologized for a gaffe (失言) in which he described his bowling skills as akin to participants in the Special Olympics, a sports program for people with intellectual disabilities.

Obama made the mistake during an interview on Thursday night on “The Tonight Show” with host Jay Leno, the first time a sitting U.S. president had been on the show.

Talking about living in the White House, Obama said he had been practicing his bowling in the home’s bowling alley and had scored a 129 out of a possible 300.

It was an improvement on the embarrassing 37 he had rolled during a stop on the presidential campaign trail a year ago. “It’s like—it was like Special Olympics or something,” Obama said.

The Special Olympics is a global nonprofit organization serving some 200 million people with intellectual disabilities, with a presence in nearly 200 countries worldwide.

Soon after the Jay Leno interview, Obama telephoned Special Olympics chairman Tim Shriver to apologize.

Shriver told ABC’s “Good Morning America” television show that Obama had apologized “in a way that I think was very moving” and that he said “he did not intend to humiliate (羞辱) the population, didn’t want to embarrass or give anybody any more reason for pain or kind of suffering.”

Shriver said people should gain a lesson from the incident.

“I think it’s important to see that words hurt. Words do matter. And these words in some respect, can be seen as humiliating or a put-down to people with special needs, do cause pain. And they do result in stereotypes,” Shriver said.

White House spokesman Bill Burton said Obama “made an offhand remark making fun of his own bowling that was in no way intended to look down upon the Special Olympics.”

“He thinks that the Special Olympics are a wonderful program that gives an opportunity to shine to people with disabilities from around the world,” Burton said.

56. What does the underlined word “akin” in Paragraph 1 mean?

A. skillful            B. similar          C. appealing              D. superior

57. Which of the following statements is true?

A. Obama loves sports and is especially gifted at bowling.

B. Obama apologized for his remarks via ABC’s TV show.

C. The Special Olympics are for various disabled people.

D. The Special Olympics don’t intend to make any money.

58. What does Shriver mean by saying people should gain a lesson from the incident?

A. Disabled people cannot be humiliated.        B. One should be careful with his words.

C. An apology for wrong words is wanted.            D. Words matter even more than actions.

59. The passage is mainly about ________.

A. Obama receiving a TV interview                       B. Obama looking down on the disabled

C. Obama apologizing for his gaffe                     D. Obama being attacked for his words
