Some people think only school children do not agree with their parents. However，it is not true．____If it's hard for you to communicate with your parents，don't worry about it．Here are some advice for you to bridge the generation gap(消除代沟)．

    ____Don't get to your parents when you are angry．Your parents possibly won't consider your ideas if you are shouting at them. And you can't express yourself well if you are angry. Go to some place to cool off.

    Try to reach a compromise(和解).____You can keep your disagreement and try your best to accept each other. Michael's mother didn't agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.

Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect to them.____

    Talk about your values(价值观). The values of your parents are probably different from those of your own.____ Understanding your values might help them see your purposes in life.

F. Communication is a problem for parents and children of all ages.

G. If you don't think you can speak to them at the moment, try writing a letter.

如图所示的是某池塘中的浮萍蔓延的面积（m²）与时间x（月）的关系：y=a^x，有以下叙述：

①这个指数函数的底数是2；

②第5个月的浮萍的面积就会超过30m²；

③浮萍从4m²蔓延到12m²需要经过1.5个月；

④浮萍每个月增加的面积都相等；

⑤若浮萍蔓延到2m²、3m²、6m²所经过的时间分别为x₁，x₂，x₃，则x₁+x₂=x₃．

其中正确的是（　　）

路德在宣传他的“信仰得救”思想时说过这样的话：“信徒得救一不靠教皇，二不靠圣礼，只有靠终生悔改，才是基督的正道。”该话的思想本质上

    You may think, salt is just a simple cooking element we shake on our food for a little extra taste. But salt is much more than that. Without salt our muscles would not move. Our nervous systems would not operate. Our hearts would not beat.

    But do not think rubbing salt into a wound will help. Doing that would be painful and not heal the wound. “To rub salt into a wound” is an idiom that means to purposefully make a bad situation worse.

    Early humans got the salt they needed to stay alive from the animals they killed. But advances in agriculture led to a diet low in salt. So, humans needed to find other sources. Those who lived near the ocean or other natural sources for salt were lucky. Those who did not had to trade for salt. In fact, people used salt as a method of payment in many parts of the ancient world. The word “salary” comes from the word “salt”.

    Salt also played an important part in population movement and world exploration. Explorers understood that if they could keep food fresh, they could travel longer distances. So they used salt to preserve food and explore the world.

    Salt was so important that, according to food historians, it was traded pound-for-pound for gold. Today, people still use the expressions “worth one's salt” or “worth one's weight in salt”. The expressions describe a person of value.

    A person might also be called “salt of the earth”. That description means he or she is dependable and trustworthy. However, when you say “I think we should take what he said with a grain of salt”you mean you accept it but maintain a degree of doubt about its truth.
