判断正误：Reporting sales figures

After a slow start at the beginning of the year when sales started out at $ 9 million and rose to $ 10 million for the month of January, there was a slight increase in February when sales went up to $ 14. 5m. Then in March we had a dramatic increase when sates shot up to a staggering $ 34m. This was after the big Trade Fair in Hong Kong, where we managed to promote our new products and capturé the SE Asin market: The-increase continued in April when sales peaked at $ 38. 5m. There was slight fall for the month of May, which was only to be expected after the rush of interest after Hong Kong, and figures hit the $ 30m. mark. They seem to stabilise there, as the June figures were much the same at $ 31. 4m. We have every to expect them to continue at this rate for the next few munths, but our target for the end of the year is to chase the $ 40m+ mark with a very aggressive marketing policy over the summer and the autumn.

16. The product under discussion is not stated.

17. The year started with a rush.

18. January saw a decline in sales.

19. In February sales declined slightly.

20. In March sales reached $34m.

21. The Hong Kong Trade Fair made little effect on sales.

22. In May the sales figures exceeded those of March.

23. The June figures were similar to the May figures.

24. If the business reaches $ 40 +, the target for the end of the year will have been reached.

25. There would be more ups than down in a chart of the January to June' figures.

Credit card companies，too，quickly saw the potential for online shopping，and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases，many credit card companies will happily refund(退还) your money and then set their claws on the company that wronged you. Now that’s buying power!

There are other bonuses for online shoppers，of course. No line­ups，for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won’t get them what they want.

When shopping online，consumers can sit down，have a coffee，and wear their slippers，not having to worry about their hair or parking，and just clicking through sale after sale. Comparison shopping couldn’t be any easier. And thanks to courier companies(快递公司) getting in on the act，you never need to wait longer than a day or two to get those all important purchases delivered right to your door.

No wonder so many companies are shaking their heads at traditional retailing and instead looking to the “virtual” world to attract online shoppers.

Linux 系统开机引导时首先启动内核，由内核检查和初始化硬件设备，载入设备的驱动程序模块，安装root文件系统，然后内核将启动一个名为init的进程。在init运行完成并启动其他必要的后续进程后，系统开始运行，引导过程结束。init进程启动时需要读取inittab配置文件，该文件确定init在系统启动和关机时的工作特性。典型的inittab文件内容见以下清单：

inittab This file describes how the INIT process should set up

the system in a certain nm-level.

Default nmlevel. The nmlevels used by RHS are:

0 - halt (Do NOT set initdefault to this )

1 - Single user mode

2-Multiuser, without NFS (The same as 3, if you do not have networking)

3 - Full multiuser mode

4 - unused

5-Xll

6 - reboot (Do NOT set initdefault to this )

id:5:initdefault:

System initialization.

si::sysinit:/etc/rc.d/rc.sysinit

10:0:wait:/etc/rc.d/rc 0

11:1:wait:/ete/rc.d/rc 1

12:2:wait:/etc/rc.d/rc 2

13:3:wait:/etc/rc,d/rc 3

14:4:wait:/etc/rc.d/rc 4

15:5:wait:/etc/rc.d/rc 5

16:6:wait:/etc/rc.d/rc 6

Trap CTRL-ALT-DELETE

ea::ctrlaltdel:/sbin/shutdown -t3 -r now

When our UPS tells us power has failed, assume we have a few minutes

of power left. Schedule a shutdown for 2 minutes from now.

This does, of course, assume you have powerd installed and your

UPS connected and working correctly.

pf::power fail:/sbin/shutdown -f-h +2 "Power Failure: System Shutting Down"

If power was restored before the shutdown kicked in, cancel it.

pr: 12345:powerokwait:/sbin/shutdown-c "Power Restored; Shutdown Cancelled"

Run gettys in standard rtmlevels

1:2345 :respawn:/sbin/mingetty tty1

2:2345:respawn:/sbin/mingetty try2

3:2345 :respawn:/sbin/mingetty try3

4:2345:respawn:/sbin/mingetty tty4

5:2345:respawn:/sbin/mingetty tty5

6:2345 :respawn:/sbin/mingetty tty6

Run xdm in runlevel 5

x:5:respawn:/etc/X 11/prefdm -nodaemon

启动init进程前，不需要经过______步骤。

A．LIIO加载内核 B．检测内存

C．加载文件系统 D．启动网络支持
