Ten-year-old Sami loved to visit his grandfather's house. The house was near the beautiful blue sea. At the seaside stood thick and tall palm trees with green coconuts hanging from them. When the coconuts fell down, Sami would break them open and drink the coconut water. Sami liked to play under the trees. It was always great fun to spend the holidays at Grandpa's place.
This winter vacation, Sami was surprised when he came to his grandfather's village. There were hardly any trees left. He saw houses built near the sea. People had cut down many palm trees and there was hardly any greenery left.
Grandpa's house was different. He never allowed his trees to be cut. He hugged each palm tree in his courtyard. He also named the two big trees near the front door--one was Petu, and the other Betu. He had planted them with his own hands and today they had become large, massive trees with thick trunks. They were tall and green and gave the sweetest, juiciest coconuts.
One night, Sami was awakened by a strange sound. He could not sleep. He tossed（辗转）and turned in bed.
Suddenly, the ground shook as if the earth was splitting. He sat up straight and then ran to Grandpa. He clung（附 着）to his grandpa tightly. Grandpa cried out, “It's an earthquake! It's an earthquake!" They ran outside the house. They thought that would be safe.
Suddenly, there was a loud sound; the earth was not splitting but the sea was roaring. People were shouting, screaming and crying, “The sea is rising! The sea is rising." The villagers started running away from the beach.
Sami watched dumbstruck（呆若木鸡）.
The waves were rising higher and higher. Sami thought, “How big the waves are!" He went into the house again and saw water coming in from all sides. He was scared.
Sami remembered his mother telling him long ago, “You must always get out of the house if the floods come too near." He ran outside the house with Grandpa. But the water came surging（汹涌） in.
Waves about twelve meters high came rushing in, drowning everything. Water was all around and everywhere.
Paragraph 1：
Grandpa held Sami's hand tightly but a huge wave separated them.

Agricultural experts say crop diversity is important to feed the1.(increase) population of our planet. They say having a large variety of plants also2.(help) to protect against possible crop diseases and future crises. But many experts say the number has decreased sharply during the past century.
One of the world's 3.(large) seed conservation projects has predicted further losses. The Millennium Seed Bank Partnership is warning that up to one hundred thousand plant species could 4. (permanent) disappear. The rich collection of genes5. decide their qualities would disappear with them.
Many experts blame climate change and loss of habitat, normal growth area, for damaging plant life. They say human6.(activity) and poorly planned, overly heavy use of land also are responsible. Modern business farming is responsible7.loss of farmers' traditional crop varieties. The "Green Revolution" of the twentieth century changed agriculture. Some experts say the use of modern commercial farming methods saved millions of people from8.(starve). Farmers planted, watered, and fertilized their crops with the help of machines. They treated their fields with chemicals9.(control) diseases and insects. Harvests grew larger and higher quality,10. another result was that some traditional crops were lost. Damage to the environment over the past century makes people believe that crop diversity also suffered.
As is known to all, most stories of kindness do not begin with formerly drug-addicted celebrity (名人) bad boys. Mine does.
When this ___took place, I was accompanying my grandmother at a huge garden party. Suddenly, Robert Downey Jr., in a nice cream-colored suit, came in. I pointed out this big movie star to Grandma ____, but she was far more interested in piling her paper plate with cheese.
As my 80-year-old grandmother rose for the _______after the party, she fell into a wheelchair ramp (坡道) nearby. The sharp ramp ______her leg open and it was bleeding.
I should have quickly taken control of the situation— but due to my blood faint, I didn’t. Luckily, Robert Downey Jr. _______.
He called an ambulance immediately, and asked someone to ____a blanket. He took off his suit and _____his suit around her leg. The cream color turned dark red. Robert surely knew how to speak to her, _____, distract her. He stayed with my grandmother until the ambulance came, _____her hand and telling her she was breaking his heart by leaving so early. I hurried into the ambulance without a word, feeling too shy to thank him.
Some 15 years after that garden party, and five years since he’d been set free from prison for possession of drugs in his car, I came across Robert in a fancy restaurant. I was ____to respect people’s privacy and never ______someone having a meal. But on this day, I decided to _______the code.
“I don’t have any ____if you remember this...” and I told him the story. “I just wanted to tell you that it was simply the kindest act I’ve ever ______.”

A memorable science project
If someone tells you to remember a phone number or address, it feels like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds you might find yourself starting to doubt your own memory. 1. Thus, it will try to throw away information that seems old or irrelevant. There are ways of helping our minds retain (记住) information, however, and in this activity you will explore ways that we lose and keep memories
Short-term, or working memory, is a way of describing most people’s abilities to store a small amount of information for a brief period of time in a readily accessible form 2. People don’t have to stop and think to remember something in short term memory.
3. Such techniques include visualizing (观察) the information in a surprising way or linking pieces of information together so that one reminds you of the other. In the case of visualizing information, this could be as simple as remembering you parked your car on the fifth floor in the D section by picturing five dogs sitting in your car! 4. If you need to purchase cereal (谷物), milk, fruit, cheese and eggs, you could imagine the cereal in a bowl, with milk pouring over it and pieces of fruit on top. Then imagine cracking an egg over everything, and it’s full of melted cheese! These may seem simple or even silly. 5. In this activity you’ll test the recall of a few friends or family members, and learn a few tricks for improving memory!
A. There are many techniques for improving memory.
B. Our brain is always seeking new and useful information.
C. Short-term memory has a short duration but is quickly and easily accessed.
D. In addition, linking information could help you remember your grocery list.
E. Retaining that information over longer periods of time becomes difficult yet.
F. Your short-term memory has a limited amount of space to store information.
G. However, they are proved to be good ways for improving memory by scientist.
For grown-ups, an afternoon snooze (打盹) is often easier said than done. But many of us have probably experienced just how simple it can be to catch some sleep in a gently rocking hammock (吊床). By examining brain waves in sleeping adults, researchers reported in the June 21 issue of Current Biology, a Cell Press publication, that they now have evidence to explain why that is.
“It is a common belief that rocking causes sleep: we fall asleep in a rocking chair soon and, since ancient times, we cradle our babies to sleep,” said Sophie Schwartz of the University of Geneva. “Yet, how this works had remained a mystery. The goal of our study was made up of two parts: to test whether rocking does indeed improve sleep, and to understand how this might work at the brain level.”
Schwartz, Michel Mühlethaler, and their colleagues Laurence Bayer and Irina Constantinescu asked twelve adult volunteers to nap on a custommade bed or “experimental hammock” that could either remain still or rock gently. All participants were good sleepers who didn’t typically nap and did not suffer from excessive sleepiness during the day. Each participant took two 45•minute afternoon naps, one with the bed still and one with the bed in motion, while their brain activity was monitored.
“We observed a faster transition to sleep in each and every subject in the swinging condition,” Mühlethaler said. “Surprisingly, we also observed a dramatic boosting of certain types of sleeprelated brain waves.”
More specifically, rocking increased the length of stage N2 sleep, a form of non•rapid eye movement sleep that normally occupies about half of a good night’s sleep. The rocking bed also had a lasting effect on brain activity, increasing slow brain waves and bursts of activity known as sleep spindles (纺锤体).
Schwartz and Mühlethaler say the next step is to find out whether rocking can improve longer periods of sleep and to find out whether it may be useful for the treatment of sleep disorders, such as insomnia (失眠).
