项脊轩，旧南阁子也。室仅方丈，可容一人居。百年老屋，尘泥渗漉，雨泽下注；每移案，顾视无可置者。又北向，不能得日，日过午已昏。余稍为修葺，使不上漏。前辟四窗，垣墙周庭，以当南日，日影反照，室始洞然。又杂植兰桂竹木于庭，旧时栏楯，亦遂增胜。借书满架，偃仰啸歌，冥然兀坐，万籁有声；而庭阶寂寂，小鸟时来啄食，人至不去。三五之夜，明月半墙，桂影斑驳，风移影动，珊珊可爱。

然余居于此，多可喜，亦多可悲。先是，庭中通南北为一。迨诸父异爨，内外多置小门，墙往往而是。东犬西吠，客逾庖而宴，鸡栖于厅。庭中始为篱，已为墙，凡再变矣。家有老妪，尝居于此。妪，先大母婢也，乳二世，先妣抚之甚厚。室西连于中闺，先妣尝一至。妪每谓余曰：“某所，而母立于兹。”妪又曰：“汝姊在吾怀，呱呱而泣；娘以指叩门扉曰：‘儿寒乎？欲食乎？’吾从板外相为应答。”语未毕，余泣，妪亦泣。余自束发读书轩中，一日，大母过余曰：“吾儿，久不见若影，何竟日默默在此，大类女郎也？”比去，以手阖门，自语曰：“吾家读书久不效，儿之成，则可待乎！”顷之，持一象笏至，曰：“此吾祖太常公宣德间执此以朝，他日汝当用之！”瞻顾遗迹，如在昨日，令人长号不自禁。

　 轩东故尝为厨，人往，从轩前过。余扃牖而居，久之，能以足音辨人。轩凡四遭火，得不焚，殆有神护者。……

余既为此志，后五年，吾妻来归，时至轩中，从余问古事，或凭几学书。吾妻归宁，述诸小妹语曰：“闻姊家有阁子，且何谓阁子也？”其后六年，吾妻死，室坏不修。其后二年，余久卧病无聊，乃使人复葺南阁子，其制稍异于前。然自后余多在外，不常居。

庭有枇杷树，吾妻死之年所手植也，今已亭亭如盖矣。

A.①③④⑥   B. ①②③④   C. ①④⑤⑥  D. ①②⑤⑥

2.对本文内容概括有误的一项是（ ）

A. 第一段叙述项脊轩修葺前后的不同变化。以写景为主，字里行间倾注作者的深情。“小鸟时来啄食”与“三五之夜”的描写，表现了作者年轻时在这里读书生活怡然自得的情趣，并用“喜”贯穿。

B.第二至第三段叙写项脊轩的变迁，回忆母亲和祖母、妻子的往事，用“悲”贯穿，隐含作者对家庭败落、光阴易逝、怀才不遇，有负亲人所望的感慨。

C.开头写小屋环境暗示家道的衰败，修葺小屋反映自己学业上的勤奋，暗示并反衬自己的不得志。

D.文章叙写自己闭门苦读的情景以及小轩多次遭火未焚的事，写得很简洁，是“悲”的进一步补充。

3.这篇课文以记叙庭中那株枇杷树作结。这样的写法的好处分析不当的一项是（ ）

A.言有尽而意无穷。

B.可以睹物思人，使人产生“人是物非”之感。

C.托物寓情，言简意丰，耐人寻味。

D.与题目“项脊轩志”照应。

4.对本文分析概括错误的一项是（ ）

A. 少年归有光是一个一个好静、安祥、勤奋和深思的少年形象。

B. 文章采用托物寄情的表现手法，表达自己对所挚爱的祖母、母亲、妻子和奶妈的怀念之情，凭借之物是项脊轩。

C. 本文无论写景、叙事或抒情，都与项脊轩息息相关，由状物而怀人而抒情，三者融为一体，做到了形散神不散。

D.文章善于撷取生活中的细节和场面来表现人物。如写祖母爱怜的言辞、离去时的喃喃自语、以手阖扉以及持象笏至的动作等，把对孙儿的关心、疼爱和期待，惟妙惟肖地表现了出来。

     Christopher Thomas,27, was a writer by night and a teacher by day when he noticed he was always

tired and was losing weight fast. Diagnosed with diabetes (糖尿病), Thomas would need to inject

himself with insulin (胰岛素) three times a day for the rest of his life or risk nerve damage, blindness,

and even death. And if that weren't bad enough, he had no health insurance.

     After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton,

Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created

diabeticrockstar. com, a free online community for diabetics and their loved ones-a place where over

1,100 people share personal stories, information, and resources.

     Jason Swencki's son, Kody, was diagnosed with diabetes at six. Father and son visit the online

children's forums (论坛) together most evenings. "Kody gets so excited, writing to kids from all over,"

says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel

alone."

     Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States,

with 24 million diagnosed cases. And more people are being diagnosed at younger ages.

     These days, Thomas's main focus is his charity (慈善机构), Fight It, which provides medicines and

supplies to people-225 to date-who can't afford a diabetic's huge expenses. Fightit. org has raised

about $23,000-in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar

Festival in the Caribbean.

     Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while

still doing his fulltime job waiting tables. "Of the diabetes charities out there, most are putting money into

finding a cure," says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only

person I know saying people need help now."
