Do you remember where you were when you heard the news about the traffic accident of a close friend? The answer is probably yes. Do you remember what you were doing on your birthday that year? You may have to think a little harder.

People remember bad memories more easily and in greater detail(细节) than good ones. Why is that? A new study finds that people do this because of evolutionary(进化的) reasons.

Elizabeth Kensinger and his partners in Boston College, US, did a study looking at this. They found negative feelings like fear and sadness caused(导致) an increase(增长) in brain(大脑) activity. This activity happens in the part of the brain that controls(控制) memories, So memories caused by negative feelings are kept in greater detail than happy or other kinds of memories.

For example, after seeing a man on a street holding a knife, people remember the knife clearly, but they forget the details of the street.

According to Kensinger, it is easy to understand this in an evolutionary(进化论的) point of view. He said that people paid attention(注意) to dangerous information so they could use that information to guide their actions and save their lives. They could also use it to plan for similar events in the future.

The scientists say more studies are needed on how we remember bad memories. This line of research will help solve the problem of stress(压力) disorder(失调).

When I was young, after church on Sundays, we would always have a delicious Italian dinner at my grandmother’s house. My grandmother’s slow-cooked sauce(酱) was the key. We would all eat, talk and laugh until our stomachs were full. After mum and grandfather passed away, my dad would still make the sauce from time to time and invite me and my brother over to his little house for a dinner full of fine food and happy memories.

When my dad died, he passed the family recipe(食谱) on to me and my daughter. We often made the sauce for dinner, but for some reason it never tasted quite right. At first, I thought we had gotten the recipe wrong, but one day I realized what was missing. On that day right before dinner, I closed my eyes and imagined my dad, mum and grandmother all sitting at the table around me. Then I placed the pasta on my fork and slowly put it in my mouth. It tasted perfect. From that moment, I realized the secret was, of course, what it had always been: Love!

One day a red rose blossomed(开花)in a forest. A pine tree not far away said, "You're so beautiful. I wish I could be lovely like you ." The rose said, "I am the most beautiful plant in the forest."Then the rose looked at a cactus(仙人掌)and said, "Look at that ugly plant. It is full of thoms(刺)! " Sometimes, the red rose would look at the cactus and say, "This plant is useless. I'm sorry I am his neighbor."

Summer came and the plants and animals needed water, but no rain fell. One day the rose saw some birds stick their beaks(鸟喙)into the cactus and then fly away. The red rose asked what the birds were doing The pine tree explained that the birds got water from the cactus.

It's not WASTE until it is WASTED!

With the World Environment Day coming, our school is now requiring every student to form a habit of sorting the waste. Here in our schoolyard we lay four different colors of rubbish bins for different kinds of rubbish. The red is for harmful waste; the blue is for waste that can be recycled (循环再用); the green is for kitchen waste; the yellow is for other waste.

The followings are some instructions for you.
Glass: Empty bottles without caps can be recycled to make new glass bottles.
Warning: Mirrors and light bulbs (电灯泡) must not be included in the glass waste.
Paper: Newspapers, magazines, boxes must be clean enough to be recycled.
Warning: Paper tissues (餐纸) and wall paper are not recyclable as paper and should be kept separately.
PMD waste: Packaging made of Plastic or Metal and Drink boxes are used to make new packaging.
Warning: Plastic pots (e.g. yoghurt pots), plastic bags must not be included with the PMD waste.
Harmful waste: out-of-date drugs, used batteries (电池), paint and oil…
Besides, if you don't need your old bikes at all, our school volunteers will collect them. We're going to fix them up and then give them away to kids who don't have enough money for a bike.
