1、关键时刻不能松气,一松气就丢一两分或更多。我一般要念叨“狠、快、刁”。我不念叨"稳"因为稳是基本功的问题, 不是临时能控制的.
2. 争取接发球抢攻.
2.1 接发球抢攻保证长球一律拉打.
2.2 正手位接短球采取进攻策略:下旋球挑打, 劈长角度, 上旋球抹角度, 拨角度, 冲.
2.3 反手位接短球是我的弱项. 反手位下旋短球我原来用搓. 可球太低短, 搓的质量不好. 我准备用王浩的反手拧. 反手位上旋短球用横打横拉就对付了.
3. 争取发球抢攻.
3.1. 发非下旋长球抢攻是常用策略, 因为对方回球基本是非下旋, 所以抢攻容易. 发急长球抢攻的原理:"只有在发力后才能侧身", 因为这时对方来不及反应, 会顺着你的球路把球回过来,你侧身等着进攻就是了。
3.2 发控制短球后第三板参照1、2。因为这也是接球的问题。
4、相持首先发力
4.1、别人用控制破了你的接发球抢攻和发球抢攻就进入了相持。
4.2、相持要首先发力。 原因是加力后对方来不及反应或容易变线失误, 会顺着你的球路把球回过来. 你侧身等着进攻就是了。
4.3、相持中如何抢先进攻参照1、2、3。因为这类似发球和接球的问题。
4.4、然后大家比拼基本功。

Bingo, that was the problem!
# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
10.1.1.1 box1 box1
10.1.1.2 box2 box2
Changed to:
# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 box1 localhost.localdomain localhost
10.1.1.1 box1 box1
10.1.1.2 box2 box2
And now when I run my script to correct the time:
# ./tsync
Shutting down ntpd: [ OK ]
ntpd: Synchronizing with time server: [ OK ]
Starting ntpd: [ OK ]

This is not the first time I've had a problem with /etc/hosts, both FC2
and FC3 on two different computers here. I connect to ATT dial up using
"network device control," [I'm in a rural area and there's no high speed
service available yet] if I click on configure [usually by accident] and
mess with settings it re-creates /etc/hosts/ without the required first
line! Something wrong there it seems?
Usually it causes the boot process to stop for a minute or so on
"sendmail" and I know what to fix, not so this time? I shut the computer
off the last few nights and rebooed in the morning without any
indication of that problem. Just when I think I know something it turns
out to be wrong!
/etc/services looks good ...
nntp 119/tcp readnews untp # USENET News Transfer
Protocol
nntp 119/udp readnews untp # USENET News Transfer
Protocol
Thanks for the help.
