英语作文have a bad memory
It should come as no surprise to anyone who's ever forgotten a
friend's birthday or been unable to remember a name, but it's easier to
lose or damage a memory than it is to enhance one.
A new report in the journal Science, however, reveals that an increase of PKMzeta, a protein that Discover Magazine calls the "engine of memory," might actually help strengthen old memories -- long after they've been formed.
The protein in question -- PKMzeta -- acts by strengthening the bond
between neurons in the brain, creating a network of connections that Discover describes
as the "physical embodiment of our memories." Researchers surmised that
by upping the level of the protein in rats (which they did by creating a
virus that expressed the gene for the protein and injecting it into
their neocortexes), they might be able to improve memory.
So what type of memories do rats actually have? I wanna fuck u,my teacher. Mainly those associated with tastes, like Saccharine and salt, WIRED reports.
In addition scientists conducted CTA or "conditioned taste aversion"
memory training, which is what it sounds like: ex
Today is Sunday. It is sunny. I don't go to school. I want to go shopping. I get up at 6:30 in the morning.I have some cereal and an egg for breakfast. I go out at 8:00. The shop is nearly . I go there on foot. Many people are in the shop. I buy a pencil . At 12:00 I go home for lunch. I have some vegetable and meat for lunch. I read a book in the afternoon. I eat some noodles and fruit for supper. After supper, I do my homework. then I watch TV. Later, I play on the computer. I lie on my bed. I listen to the radio. I have a happy day
It was during a weekend. Mum gave me two tickets for a film and told me she was too busy with the endless housework to go with me . She told me to keep the money if I could sell the extra ticket. I was very happy, of course . At that time , a ticket only cost 20 fen . But to me, a little girl of 12,20 fen seemed quite a lot.
I reached the cinema in a great hurry. Holding the ticket in my hand, I began to look for a buyer. A handsome young man noticed me and the ticket in my hand. He came towards me with a big smile, “You've got an extra ticket?”
“Yes,”I nodded .
“That's great . Say , how much?”
“ Oh ,”he thought for a while and then took out a ten-yuan note from his wallet.
“I'm very sorry, but I've only got this note.” Seeing I was confused① , he added, “Then, how about waiting for a while and I'll give you the money after I have changed it in the cinema's store?”
Without much thinking, I agreed. Then we went to the cinema together. He walked fast. I could hardly keep up with him. By and by, he left me further and further behind. Soon he disappeared in the Gents②. I stood there without knowing what to do. Suddenly I seemed to realize the handsome young fellow had cheated me. He had saved twenty fen, but lost his honour.
The Worst Day
Today is rather unfortunate for me. I got up very late this morning
because I watched a very interesting TV program last night and did not
go to bed until midnight. After getting up, I suddenly discovered the
electricity from the mains had been cut and there was no water in the
water pipe. I couldn’t cook my breakfast. I hurried to the bus station
with an empty stomach but I missed the first bus. The second bus
would not arrive until an hour later. When I finally arrived at our
school, the first two classes had already finished. While I was sitting
down at my desk, I found that I had left my books at home. I only
brought an empty school bag to school. What a worst day I had!
Everyone has his or her experience that is unforgettable. Mine happened when I was five, when my parents took me to the city zoo. It was a hot summer so most animals were laying down to stay cool. As we walked around, I saw a panther crouching by a hill in its enclosure. All of a sudden, the panther leaped over the wall and jumped on the back of an old lady who was eating a hamburger. The old lady let out a high pitched scream and fell down from her seat, sprawling on the cement pavement and passed out. The panther did not attack the old lady, but picked the hamburger dropped by the lady. After swallowing the hamburger, the panther started walking around the cafeteria with many visitors looking at it. One kid saw the animal outside, and called excitedly, “Mommy! Look! I want to pat the Panther!” The kid ran to the animal. By the time the panther was laying on the ground. The little boy went to the panther and sat on its back. The panther stood, with the boy on its back, started running towards the gate of the zoo and disappeared into the city in the dusk twilight. I took a few pictures of the boy riding the panther, and this, was an experience I will never forget.
