假如你是Xiao Dong，Xiao Liang给你来了一封信，请你根据信的内容写一封回信。信的开头已给出，请把信补充完整。
Dear Xiao Dong,
I like your programs very much. I’m writing to ask you something about American social customs. My American friends want me to join them in their dinner party. I’m very happy and have decided to go, but I’m a bit worried about it. The social customs in my country are different from there, so I’m afraid of making some mistakes.
Should I bring a present, such as sweets or flowers? Should I arrive on time or a bit late? At the dinner table, how can I use fork and knife? How can I let the family know that I’m thankful for their kindness.
Yours’
Xiao Liang

Lake Victoria is the largest lake in Africa. It is also the second largest lake in the world. It is an important lake because it is one of the sources(源头) for the longest river in the world, the Nile River. Lake Victoria provides a source of water, food, and power(电力) for several African countries. Lake Victoria is a big part of African life.

Unfortunately, Lake Victoria has a problem. It is shrinking. There are several power stations at Lake Victoria in Uganda. These are on the Nile River, and besides producing power, they keep the water of the lake at a certain level. For the past forty years, that level has been 11.9 meters. Over the last several years, the water level has dropped by about 2.5 meters. There seem to be several reasons for this drop.

One possible reason is drought(干旱). Drought has been very bad in the area since 2000. Lake Victoria gets all of its water from rain, so the drought means less water in the lake.

However, some environmentalists believe that the real problem is the power plants(工厂) on Lake Victoria. Uganda depends on those power plants for most of its power, and they made the power plants larger in 2000. Many people believe the power plants have been taking too much water off Lake Victoria. As a result, they have been asked to use less water until Lake Victoria goes back to its old level.

Whether the low water level is caused by drought or power plants, the result is the same. This is already a poor area of Africa, where many people live a really hard life. People, animals and plants around Lake Victoria will suffer even more from low water levels on the lake. Many people need Lake Victoria for fishing or growing food. Fish need the water to live, and animals need it for water. Plants around the lake will die without the water, and then more animals and people will suffer. Unless the lake fills soon, many people will suffer and die.

We use passwords(密码)to keep our personal information secret and safe, but some passwords we use may not be as reliable as we think.

Splash Data, a computer security company, recently released a list of the 25 worst passwords of 2011.This list is based on the research of hackers’ files containing stolen passwords. According to the list, “password” is the worst and most common password. Many others on the list are numbers in order either forward (for example,1234) or backward. Letters on the keyboard in order, such as “qwerty” are also common, as well as some first names and animals. “Hackers can easily break into many accounts(账户) just by trying common passwords again and again, ” said Morgan Slain, CEO of Splash Data.

How can you make a strong password? It should be eight characters or more, with a mix of letters, numbers and symbols. One way to create a long and easy-to-remember password is to separate short words with spaces or numbers. Having safe passwords is necessary for surfing the Internet safely. But it’s not the only thing you must do to keep safety online. Here are some other web safety tips:

●Never give out information that will allow someone to find you offline. That includes your full name, address and phone number.

●Don’t include your real name as part of your online screen name.

●Never meet people you met on the Internet in person. If you insist on breaking this rule, meet in a very public place and consider taking an adult with you.
