@echo off
for /r %%i in (*.txt) do (
echo 1234 >"%%~dpni1%%~xi"
type "%%i" >>"%%~dpni1%%~xi"
ping 127.1 /n 1 >nul
del "%%i"
move /y "%%~dpni1%%~xi" "%%~nxi"

if($a=3 || $b=3) 注意这里是用的一个等号一个等号是赋值注意if里面的空号在$a $b赋完值后还进行或运算而在进行或运算的时候 $a $b 数据类型自动转换为了布尔值

$a=0; $b=0;
if($a=3 || $b=3){
var_dump($a);
var_dump($b);
$a++; $b++;
var_dump($a);
var_dump($b);
}
echo $a.",".$b;

Have you ever heard an echo of your voice? Have you ever heard an echo of your voice? An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”. We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(纸板筒). Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear. A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far. We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them. 小题1: Which is the right order of hearing our echo in a very large, empty hall? a. We hear the reflected sound b. The sound returns to us c. The sound hits the walls d. We make a sound A．c, b, a, d B．c, a, b, d C．d, c, b, a D．d, b, c, a 小题2:. From the text we learn that __________ . A．reflected sound is useful only to blind people B．people haven’t made use of reflected sound yet C．bats use reflected sound to fly and get food D．whales don’t use reflected sound as they live in the sea 小题3: If you haven’t got a megaphone, ____ will help you to make your voice travel farther. A．a long piece of wood B．a roll of cardboard C．a thin thread D．a long piece of silk 大鞋子小脚丫1年前1: 烟雨彼岸共回答了14个问题 | 采纳率78.6%
