All over the world the need for more laptops and computers increases each year．Networks have been part of our life．Probably everyone with a portable device （移动设备）has once logged on to a public WiFi network without paying for it，while they are having a coffee，on a train，in a shopping mall or at a hotel．However，is this kind of public WiFi network safe？
Some networks are better protected than others because encryption （加密）methods are used．Therefore，they are safer than others．But a survey in 2015 showed that more than 950 million records were not protected，including addresses，emails，birth dates，phone numbers，passwords and so on．These open WiFi networks are really not safe，because it is very easy for hackers （黑客） to break into the operating system and get people's private information．
Most smartphones and laptops，by themselves，search and connect to WiFi networks．They usually prefer a network with a connection that has been used before．Hackers'devices are able to record these searches and look like the trusted WiFi networks．When these smartphones and laptops log on to the networks which are not real，hackers can easily steal their private information．
So next time，when we want to use our laptops or our smartphones in public places which offer free WiFi networks，please think it twice or take safe measures before using them．
42．Why do people like to go log on to a public WiFi network？
A．Because it can provide useful information．
B．Because the owner of the network is polite．
C．Because it is free．
D．Because it is safe．
43．We can learn from the passage that
A．not all the public WiFi networks are safe
B．none of the public WiFi networks is safe
C．in 2015more than 950million records were protected
D．there is no way to protect our private information
44．Hackers would probably get the following EXCEPT when we connect our laptops or smartphones to a public WiFi network．
A．our birth dates
B．our passwords
C．our phone numbers
D．our smartphones
45．Which of the following can be the best title of this passage？
A．Don't Use Public WiFi Networks
B．Why the Public WiFi Networks a Possible Danger
C．We Needn't Protect Our Private Information
D．Why Hackers Break into the Operating System．

Clothing（服装） is a language． We can look at traditional clothing to know more about culture．
Africa has a long history and a rich culture， and this is shown in traditional dress． The three colours﹣red， gold and green， are often used in the clothing． The first colour stands for the blood of millions of people who fought for freedom； the second， rich resources of the African earth； and the third， the grassland of home．
Because clothing has strong social meanings， people are very careful in choosing what to wear． It would be a serious mistake to wear the wrong clothes， or to dress in the wrong way． For example， in Ghana， a woman should wear her waistband（腰带） differently according to the importance of the social event．
Traditional dress also tells us about everyday life． African designs are famous for loose （宽松的） clothing． The temperature there can be very high during the daytime but very low at night， so it requires that the clothes are comfortable for daily life．
Today although more and more young people like wearing Western clothes， especially in big cities in Africa， traditional African dress is still quite valuable． This is because it has deep cultural meanings．
