       Could you imagine your parents choosing your husband or wife for you? And can you imagine not setting eyes on him or her until your wedding day? This situation is common in India, the Middle East and many parts of Africa．Marriage customs around the world often differ from our own．We don’t realize that people in other places often get married in very different ways and with different motives．

In many countries, marriage is a practical matter．A marriage provides a safe and stable home for the husband and wife．It also joins two families, which benefits the couple’s parents and makes them happy．Marriage also brings children, making sure the couple will be taken care of in old age．Because a marriage is important for the whole family, some cultures don’t let young people choose whom to marry．

Just as there are many different reasons for marriage, there are also many different wedding rituals．Every culture has its own ways of bringing good luck to the happy couple．In a typical Western wedding, the bride seeks good luck by wearing “something old, something new, something borrowed and something blue”．Something old represents the past．Something new represents success in the future．Something borrowed reminds the bride she can get help from her friends and family．And something blue reminds her to be true to her husband．

In Poland, one wedding tradition is not only lucky, but also very practical．The wedding guests pin money to the bride’s dress while she is dancing．The money is meant to bring luck and to help the young couple build their new life．In Bermuda, the young couple plants a tree in the yard of their new home．Once they move in, they take good care of the tree and make it grow．The planting of the tree is a good metaphor（比喻） for marriage．A truly good marriage is something that grows with care．

将4molA和2mol B放入2 L密闭容器中发生反应2A（g）＋B（g）2C（g）△H＜0  4 s后反应达到平衡状态，此时测得C的浓度为0．6 mol／L。下列说法正确的是

A．当c（A）︰c（B）︰c（C）＝2︰1︰2时，该反应即达到平衡状态

B．达到平衡状态后，若只升高温度，则C的物质的量浓度增大

C．达到平衡状态后,若温度不变,缩小容器的体积,则A的转化率增大,平衡常数增大

D．4 s内，v（B）＝0．075 mol／（L·s）
