标 题: 咒骂朱海洋的人请闭嘴
发信站: BBS 未名空间站 (Fri Jan 23 09:39:38 2009)
你们根本不认识他,对他为人一点都不了解,有什么资格对他进行辱骂和嘲讽?他是杀人了,是犯罪了,我不否认。但是我想说的是,一个人被别人恨到要杀她的地步,说明她自身肯定存在着及其严重的问题。在这件事发生以前,朱海洋的为人是他身边亲朋好友有目共睹的,热心善良勤奋执着,我们在得知这一消息时的第一反应都是不敢相信和无法想象。但是我们坚信,这件事件的背后肯定存在着一些目前还不是广为人知的原因。
一个人犯了很严重的错误,必然会受到相应的惩罚,老天是公平的。朱海洋也一样,但是这是法律的事情,和你们无关,你们没有资格咒骂他。就算他应该骂,也是被她和她的家人,不是你们。请你们不要对他进行人身攻击,他不是WSN,凤凰男,更没有精神病。他是出身于普通学校,可能你们高考是比他考得好,但是这不能说明什么问题,我想他可以在VT做TA读PHD已经说明了他的能力和实力。更不用说英语,有多

7月23日10:47,王小姐来电:我们办公室在湖墅南路××大楼,刚才进小偷了,就是日
全食天最黑的时候。我们大家都在露台上看日全食,没有感觉他进来,办公室是敞间,
门开着通风的,他进来偷了我们副总的手机,手机还蛮贵的。
记者核实报道:窃贼光顾的是一家拍卖行女副总的办公室。办公室在三楼,紧靠露
台。
这位姓徐的副总说,昨天上午9:35,写字楼开始“骚动”,脚步声“咚咚咚”,
有人喊,盖住啦!盖住啦!拍卖行占据地利,推开落地窗就是露台,员工争相跑到露台
,仰头看天,一边看一边叫。
“日全食就几分钟,千万不要错过了……我赶紧放下手里的活,也凑过去看。”
徐副总说,最近整座写字楼都在搞节能行动,白班不开电灯、不开空调,开门通风
。徐副总走上露台时,“太阳慢慢被遮住,天像被幕布遮起来……”
写字楼的监控记录了“天像被幕布遮起来”时,三楼通道里一个男子的行踪――
9:39,男子出现。他个头不高,微胖,肩挎挎包,手上戴着亮闪闪的手表(记者注
:也许他要掐准“食甚”的时间?),手机贴在耳朵上,眼睛不停地往两边的办公室张
望,有时还跨进办公室半步,又抬头望望门牌号,退出来。好像找人的样子。

In my dream,
you are standing there looking at me with the most beautiful smile,
a little shy, but elegant and calm.
Yeah, I know it's you,
it's you...
I know it even without a word with you.
I know it through your smile,
through your eyes,
through the flush on your face.
I walk to you with the delight from my heart,
look into your eyes,
hold your tender hand up slowly and touch it with my lips.
From your eyes, I know you are waiting for me.
I hold you in my arms, tighter and warmer, I know th

新浪科技讯 北京时间10月28日消息,美国宇航局网站近日公布了一张火星高分辨
率照片,照片显示火星浅红色地表上有纵横交错的黑色条纹,好似刻意为火星打造的“
纹身”。
火星“纹身”是由正在绕火星飞行的“火星勘测轨道飞行器”携带的“高清晰度科
学实验成像”(HiRISE)机所拍摄的。事实上,该相机更像是一部口径为半米的天文望远
镜,其能够从超过300公里的高空看到火星表面直径小于30厘米的物体。图森亚利桑那
大学负责操作“高清晰度科学实验成像”照相机,美国科罗拉多州鲍尔航天科技公司负
责制造该仪器。
火星表面扭曲的黑色条纹似乎被有意印刻在火星浅色的沙丘上。科研人员认为这些
火星“纹身”是火星尘旋风所导致的。火星尘旋风,又被称为“风魔”,是火星表面强
烈增温而生成的小旋风,以卷起地面尘沙和轻小物体形成旋转的尘柱为特征。
火星尘旋风的形成方式跟地球上的尘暴一样,在地球上干燥炎热的沙漠地区也有类
似的现象。白天地面温度升高,使得地表气温升高。这一层热空气上升,位于上方的冷
空气下降,形成垂直对流体。水平阵风导致该对流体发生旋转,形成尘卷。尘卷在火星

For the first time in nearly two decades, students in New York City’s
public middle and high schools will be required to take sex-education
classes beginning this school year, using a curriculum that includes lessons
on how to use a condom and the appropriate age for sexual activity.

The new mandate is part of a broader strategy the Bloomberg administration
announced last week to improve the lives of black and Latino teenagers.
According to city statistics, those teenagers are far more likely than their
white counterparts to have unplanned pregnancies and contract sexually
transmitted diseases.
“It’s obviously something that applies to all boys and all girls,” said
Linda I. Gibbs, the deputy mayor for health and human services. “But when
we look at the biggest disadvantages that kids in our city face, it is
blacks and Latinos that are most affected by the consequences of early
sexual behavior and unprotected sex.”
The change will bring a measure of cohesion to a patchwork system of
programs largely chosen by school principals.
It will also bring to New York the roiling national debate about what,
exactly, schools should teach students about sex.
Nationwide, one in four teenagers between 2006 and 2008 learned about
abstinence without receiving any instruction in schools about contraceptive
methods, according to an analysis by the Guttmacher Institute, which studies
reproductive health. As of January, 20 states and the District of Columbia
mandated sex and H.I.V. education in schools. An additional 12 states, New
York included, required H.I.V. education only, according to a policy paper
published by the institute.
New York City’s new mandate goes beyond the state’s requirement that
middle and high school students take one semester of health education
classes. The city’s mandate calls for schools to teach a semester of sex
education in 6th or 7th grade, and again in 9th or 10th grade, suggesting
they use HealthSmart and Reducing the Risk, out-of-the-box sets of lessons
that have been recommended since 2007. A city survey of principals last year
found that 64 percent of middle schools were using the HealthSmart
curriculum.
For the Bloomberg administration, which last week announced a three-year, $
130 million initiative to improve the lives of young minority men in the
city, the sex-education mandate joins a number of other public health
efforts — like the mayor’s push to reduce residents’ intake of salt and
sugary sodas — that have sometimes been criticized as interventionist. It
is also unusual because the city does not often tell schools what to teach.
“We have a responsibility to provide a variety of options to support our
students, and sex education is one of them,” the chancellor, Dennis M.
Walcott, said in an interview on Monday.
Parents will be able to have their children opt out of the lessons on birth-
control methods. City officials said that while there would be frank
discussions with students as young as 11 on topics like anatomy, puberty,
pregnancy and the risks of unprotected sex, the focus was to get students to
wait until they were older to experiment. At the same time, knowing that
many teenagers are sexually active, the administration wants to teach them
about safe sex in the hopes of reducing pregnancy, disease and dropouts.
Some are already preparing for a backlash.
“We’re going to have to be the bridge between the chancellor’s
requirements and the community,” said Casimiro Cibelli, principal of Middle
School 142 in the Baychester section of the Bronx, where many of the
students come from immigrant, religious families with traditional views on
sex. “Hopefully, we’ll allay their concerns because of their trust in us.”
At Mr. Cibelli’s school, the current semester-long health course does not
stray from subjects like nutrition and physical fitness.
The new classes, which will be coeducational, could be incorporated into
existing health education classes, so principals will not have to scramble
to find additional instructional time. The classes would include a mix of
lectures, perhaps using statistics to show that while middle school students
might brag about having sex, not many of them actually do; group
discussions about, for example, why teenagers are often resistant to condoms
; and role-playing exercises that might include techniques to fend off
unwanted advances.
Schools that have not been offering sex education — the number is unclear
because the city’s Department of Education has not kept a tally, a
spokeswoman said — can hire a teacher to do it or assign the task to one
who is already on the staff. The department will offer training sessions
before the start of classes Sept. 8.
Some New Yorkers of older generations remember explicit sex-education
classes with frank talk about libido and demonstrations of how to use a
diaphragm.
In 1987, the state mandated the adoption of an H.I.V./AIDS curriculum in
every school. For students in the city, that has meant at least five class
sessions each year, from kindergarten through 12th grade. In those classes,
younger students are taught to avoid touching open wounds, and older ones
are talked to about sex, but not necessarily about preventing pregnancies.
Opposition from religious groups and school board members eventually
defeated a city mandate approved in the 1980s for a sex-education curriculum
. But a survey by NARAL Pro-Choice New York in 2009 found that 81 percent of
city voters thought sex education should be taught in public schools.
High schools in New York have been distributing condoms for more than 20
years. In the new sex-education classes, teachers will describe how to use
them, and why, going where some schools have never gone before. To others,
though, the topic will be familiar territory.
At John Dewey High School in Gravesend, Brooklyn, 10th graders already take
a nine-week course called Human Sexuality, which the school’s health
teachers designed some years ago and which covers many of the same topics
that the city will require.
Some schools have relied on nonprofit or community groups like Planned
Parenthood and the Door to teach their sex-education classes, an arrangement
that is likely to continue once the new policy takes effect.
Mary Cheng, a health teacher at Murry Bergtraum High School in Lower
Manhattan, said she devoted two months of students’ required five-month
health class to sex education, combining lessons from the recommended high
school curriculum with materials of her own. Ultimately, it will be up to
schools to design the lessons; they will have until the beginning of the
second semester to begin the classes.
“We will work with our schools and school communities to ensure they are
prepared,” Mr. Walcott said.
