袁枢，字机仲，建之建安人。幼力学，尝以《修身与写赋》试国子监，周必大、刘珙皆期以远器。试礼部，词赋第一人，教授兴化军。

    为礼部试官。常喜诵司马光《资治通鉴》，苦其浩博，乃区别其事而贯通之，号《通鉴纪事本末》。参知政事龚茂良得其书，奏于上，孝宗读而嘉叹，以赐东宫及分赐江上诸帅，且令熟读，曰：“治道尽在是矣。”

    他日，上问袁枢何官，茂良以实对，上曰：“可与寺监簿。”于是以大宗正簿召登对，即因史书以言曰：“臣窃闻陛下尝读《通鉴》，屡有训词，见诸葛亮论两汉所以兴衰，有戒，垂法万世。”遂历陈往事，自汉武而下至唐文宗，偏听奸佞，致于祸乱。上曰：“朕不至与此曹图事帷幄中。”枢谢曰：“陛下之言及此，天下之福也。”

    兼国史院编修官，分修国史传。章悖家以其同里，宛转请文饰其传，枢曰：“吾为史官，书法不隐，宁负乡人，不可负天下后世公议。”时相赵雄总史事，见之叹曰：“无愧古良史。”

    权工部郎官，累迁兼吏部郎官。两淮旱，命廉视真、杨、庐、和四郡。归陈两淮形势谓两淮坚固则长江可守徒知备江不知保淮置重兵于江南委空城于淮上非所以戒不虞瓜洲新城，专为退保，金使过而指议，淮人闻而叹嗟。谁为陛下建此策也？”

    迁大理少卿。通州民高氏以产业事下大理，殿中侍御史冷世光纳厚赂曲庇之，枢直其事以闻，人为危之。上怒，立罢世光，以朝臣劾御史，实自枢始。诏权工部侍郎。因论大理狱案请外，有予郡之命，既而贬两秩，寝前旨。光宗受禅，叙复元官。

    擢右文殿修撰、知江陵府。江陵濒大江，岁坏为巨浸，民无所托。楚故城楚观在焉，为室庐，徙民居之，以备不虞。种木数万，以为捍蔽，民德之。开禧元年，卒，年七十五。

    创作《易传解义》及《辩异》《童子问》等书藏于家。

如图是一个圆台，它的主视图是（　　）

    A family is a collection of people who share the same genes（基因）but cannot agree on a place to pull over for lunch. Ed and I, plus his parents and sister Doris and eight-year-old niece Alisha, are on a road trip to Yosemite. Ed wants Subway, I want. In-N-Out Burger, Doris wants Sonic. In the end, we compromise on McDonald's, where Alisha will get an action figure.

    It's a three-hour drive to Yosemite, but we're taking a little longer, as we're working in a tour of Highway 80's public restrooms. As the saying goes, “Not one bladder（膀胱）empties but another fills.” Many of these restrooms belong to gas stations. I prefer them to the high-tech ones on planes.

    We get back on the road. Ed is driving now. When all the tabloids（小报）have been read, the travel has grown tedious and anyone under age 12 asks “Are we there yet?” at ever-shortening internals. Just outside Manteca, California, we stop for coffee. At a Starbucks checkout, Ed buys a CD of Joni Mitchell's favorite musical picks. The hope is that it will have a calming effect.

    As we pull back onto the highway, it starts to pour. Then something amazing happens. As we climb the mountain, the rain turns to snow. The pines are spotted with white. We're struck dumb（说不出话）by the scene outside. For a solid 15 minutes, everyone forgets about their bladder, their blood sugar and the temperature. Alisha has never seen snow, so we pull over to make snowmen and catch snowflakes on our tongues. Then Ed realizes we need tire chains, and we have to turn back and drive 30miles to Oakhurst. “Good,” says Doris. “There was a very nice restroom there.”
