THE ARAB IN THE DESERT
An Arab was walking alone through the desert when he met two men. The
men looked worried. It seemed that they had lost something. The Arab
went over to them.
“Have you lost one of your camels?” he asked them.
“Yes,” they said.
“Was he blind in the right eye and lame in the left foot?” asked the
Arab.
“Yes, he was.”
“Had he lost a tooth and was he carrying corn?”
“Yes,” said the men. “Please tell us where he is.”
“I don’t know where he is,” s... 阅读全帖 |

cardboard or newspaper on top of the grass then cover with 3-5 inches of
mulch. The grass will be dead under cardboard or newspaper in 3 months.
cardboard or newspaper will decompose within 9 months in the soil. This is

我LD建议grass lawn park. 我查了，比较一下 grass lawn park 和 Lake Sammamish
Park：
grass lawn park：
http://www.redmond.gov/insidecityhall/parksrec/facilities4.asp
4pm 到晚上的reservation fee 是$90
好处：离LZ家近；亭子很大，不受风雨影响；旁边是一新造playground，很受孩子欢迎
,有孩子的同时吃和照顾孩子两不误；那park去年重建，很漂亮；好像知道的人不多，
我LD常带孩子去那，都见那空的，所以不预订也可能有位。
坏处：没有湖景；只一个Picnic Shelter，如果被占了就不能去。
Lake Sammamish Park：
有不同点可以预订，最好（大）的是$200, (小的还没问价）
好处：大，有湖景， 没预订也能找到一空地
坏处：人多，没预定的位置通常有人，不一定占到有烧烤炉的位置，孩子playground
可能较远 ，除非占在那旁边空地 |

Please sod bare areas in front yard.
信中没有提到什么时候必须修理好。没有给什么deadline.
请问，现在买草籽恐怕来不及了吧？那么只有直接去买grass sod来补上了。
原来常常收到Homedepot的广告 --- $1 per square feet. 现在真要买了，反而找不到
地方了。请问最便宜的grass sod在哪里去买？大概多少钱？
最后，请问买来grass sod， 怎么样铺上去？希望不要铺上去后3天就死光光。

发帖数: 5839 | 9 COMMON CARP, GRASS CARP, SILVER CARP和BIGHEAD CARP这几个叫法挺合理，各叫各的
挺好
中国引进的是walleye的欧洲表亲zander吧，如果大家不嫌麻烦，分别叫成欧洲大眼狮
鲈和美洲大眼狮鲈就挺合理
黑龙江的pike官名黑斑狗鱼，北美的northern pike叫白斑狗鱼，这种叫法早已形成，
挺合理。
chain pikeerel就是屁股肉，小很多，还有更小的grass pike，这两个估计不会引进，
中文就直译链狗鱼或草狗鱼就可以了。你给出的第二张图是redfin grass pikeerel
muskellunge本身就有三种，spotted，clear，barred，一般叫大狗鱼，叫狼鱼有点怪
，和pike谁吃谁不一定，看大小。另外和northern pike 杂交的叫tiger muskellunge
，直译虎纹大狗鱼就挺好
CRAPPIE中国的叫法和美国相去甚远，刺该太阳鱼是本名，被叫得一塌糊涂，皮皮，花
花太搞了，可爱皮其实是音，意俱佳的译法，叫鲫没有任何道理 |

被横扫，于是上一桌来打。
我让伊跟桃心打，结果说他要赶火车回城里，最后一局要求和我打。我又让伊和grass
打，看看他们遭遇战如何打，还是不行。我只好披挂上阵，今天看来状态不错，不吃球
失误少，拿下第一局。第二局起风云突变，忽然发现打不死他了，几板下去都能防回来
，球而且很怪，轻飘飘不往前走，我借不到力失误很多，连丢两局，第四局依然没起色
。对方10:7领先，我发球得一分，对方第一个发球没得分，关键时刻他说发一个不寻常
发球，我说失误，他还真听话，10：10。又打了6，7个丢司赢了第四局(这心理素质杠
杠的）。第五局打了半场好局，5:1交换场地，结果换定丢了5分，6：6。想想怎么办，
发了两个球得分，对方又失误送一分，最后11：7拿下。没让伊全胜回家。其实我觉得
香港正胶和grass打他可能更上风。
后来又和grass打，今天他想赢怕输有想法，失误也多了，没有保持上次的状态。看来
打球还是要拼啊，不能想太多。 |

接着:
豆豆:菲菲
CLAY:9:2
GRASS:1:2
HARD:3:3
三种场地,各自的weight分别是
CLAY: a
GRASS: b
HARD: c
where a+b+c = 1
如果你认为三种场地是均等的话, a = b = c = 1/3
(9-2)*1/3 + (1-2)*1/3 + (3-3)*1/3 = 2 > 0
综合豆豆还是占优.
当然如果你想菲菲对豆豆平手甚至占优,完全可能!咳,继续分析:
(9-2)*a + (1-2)*b + (3-3)*c = 7a - b <= 0 ===> 7a <= b
言下之意,当你认为GRASS比CLAY要重要7倍甚至更多,菲菲就立于不败之地了!
所以不用争,这胜负之差完全是你的一念之差. it is all about your mind! |

发帖数: 4546 | 25 又看到有人提到纳豆与狒狒的对战记录，就到官网上去复习了一下，总结如下：
1. 总记录是18：10，纳豆占优。泥地交手14次，12：2；其余14次，6：8.
2. 04-07交手14次，8：6，泥地7次，6：1，其余7次，2：5.
3. 08-12交手14次，10：4，泥地7次，6：1，其余7次，4：3
4. 两段时期纳豆各有一次5连胜。前一次是4场泥地加上迪拜，后一次是3场泥地加上温
网和澳网。
我的看法：
1. 不管你怎么辩，这个记录对老费不可能有利。虽然记录的一边倒主要是因为纳豆在
红土上的无敌，但总体上老费在其它场地并没有能找回多少场子，尤其是在自己的巅峰
期，纳豆刚出来时就输了迈阿密和迪拜。作为对比，小德在红土上同样是2：13落后，
但在硬地上以10：4领先，总的记录就不是那么难看了。如果当初老费那两场能拿下（
按当时的实力应该是可以的），那么记录也会好看点；可惜没有如果，所以奶粉不要怪
纳豆不给老费机会，而应该怪老费自己轻敌。
2. 08以后，老费开始下坡，而纳豆步入巅峰，这时老费不仅在泥地打不过，在其它场
地也难说优势了，输了温网和两次澳网。纳豆的年龄优势在那儿，这个记录只... 阅读全帖 |

（麦冬）， which you can get from HD. It looks like narrow-bladed grass,
evergreen, fast-spreading, grows in any soil and tolerates drought, sun or
shade. It's tough as hell and will choke out all weeds. Its weakness is that
it won't tolerate your walking on it like a turf grass. Therefore as long
as if you mow frequently, it won't invade your grass. Once it is established
, you can pant some flowering shrubs in it. |

Fast growth turf for a temporary lawn"，再看成分， 悲剧了，88.9% annual

那就是勤剪草，不要把grass chipping装袋。只要温度湿度合适，剪下来的草只要一两
个月就可以变成最好的compost。这样每个礼拜都加上薄薄的一层compost，可以使得草
地保水而且健康。
我每年只是在九月下旬把grass chipping装袋两次，然后撒草籽。两次装袋的草，就可
以装满我一整个cold compost bin。加上收起的树叶，完全够下一年菜地使用。
我最不理解的就是，每次花钱把grass chipping运走，到头来又要花钱把compost加到

发帖数: 1709 | 43 You should ask your neighbors what type of grass is in your yard, or post a
picture here. A warm
season grass is most likely a hybrid and doesn't produce viable seeds, but
it can creep into bare spots to repair itself. The safest way is to buy some
fine mulch or compost and spread them to bare spots, which provides an
insulating layer to keep moisture and suitable temperature, thus attracts
nearby grass to creep in. |

You can still mow your lawn, if it is dry and above freezing temperature for

In general you should increase the mowing height towards summer (say 3.5" or
even 4") and decrease the mowing height towards winter (say 2.5"). The
danger of high grass in the winter is that they mat down easily during snow
