One day, Grandpa and Grandson came to a pond where many children were driving their remote - controlled boats. Watching the children racing boats happily, the boy felt 　36 . He knew his parents couldn’t afford such a boat. And Grandpa had no chance of giving him such a gift　 __37 his pension was small. Grandpa felt the boy’s 　38 . He looked around until his eyes　 __39 on a bench next to a big pine tree.

Then, Grandpa led the boy to the bench and sat down. “Grandpa, I want a 　40 　like that,” the boy said. “I know,” grandpa patted the boy on the shoulder.

　 Some time later, Grandpa 　41 a big piece of pine bark fallen from the tree, some sticks and grass. Grandson looked 　42 at what he was doing . To the boy’s surprise, Grandpa made him a big bark ship with a beautiful white 　43 made of a handkerchief.

　 “Now, let’s see how it 　44 !” Grandpa gave the ship to the boy. The boy 　45 the boat carefully into the water. A remote - controlled boat went by, _ 46 waves and splashing their boat wet. “Oh, no !” the boy cried.

　 Out of nowhere came a breeze and the sail 　47 the wind. First slowly, then faster the boat

braved the water. The wind 　48 the boat around the pond. And finally it drove the boat back to

them. The boy took the boat out of the water with eyes full of 　49 .

“Look at the 　50 boats,” Grandpa said. “They are great, but you saw 　51 two of them ran out of batteries. Our boat is remote - controlled by a source that will never be 　52 .”

　 “By what?” The boy asked.

　 “It is controlled by 　53 　Humans run out of energies when trying to control everything. But when we 　54 our need to control and let nature 　55 our boat, it’s a journey and a wonder to look at.” The boy nodded, leaving the pond with grandpa, with the bark ship carefully in his arms.

Chuck，unlike other frogs，didn't like catching flies himself. But he did love eating them.

Some frogs thought Chuck was lazy. Some believed he must think he was too good for them. Some thought Chuck was the strangest frog ever.

That didn't matter to Chuck. Each morning，Chuck jumped over and sat under the spider's web. Then when Lady Eightlegs went off to dip (浸) her feet in the pond，Chuck ate flies from her web.

One morning while Chuck was enjoying his fly breakfast，Lady Eightlegs returned and caught him.

“You're the one who keeps eating my flies！”she cried.

Chuck jumped away and into the pond. Now there was an idea！Why not spin (结) his own web?

He collected some vines (葡萄藤) from a nearby farm. Then he began to spin his web. He worked on his web for hours，until very late at night. And then he fell asleep.

When he woke up the next morning，he found that he got caught by the vines.

“Help！”he shouted.

Lady Eightlegs looked up from the edge of the pond. She hurried up to help Chuck out of the vine web.

“No matter how hard I try，I can't spin a spider's web，”Chuck said.

“Of course not，”Lady Eightlegs said. “You're a frog. Frogs can't spin spider's webs any better than spiders can swim，I guess.”

“But I always see you in the water，”Chuck said.

“I only wade in (蹚水) up to my knees，”Lady Eightlegs sighed. “How wonderful it would be to swim in the middle of the pond and float (漂浮) peacefully under the sun.”

Chuck smiled，“I have an idea.”

From that day forward，Chuck carried Lady Eightlegs out to the middle of the pond，where they floated and played together. When they returned to land，they shared a breakfast of flies from her spider's web.

It wasn't exactly an ordinary friendship. But Chuck was not an ordinary frog.

Once upon a time a king, in the company of his ministers, went to the imperial garden for a walk. When he was walking around a pond, a strange idea 26 upon him and he asked, “How many buckets(桶) of water are there in the pond?” The ministers looked at each other,  27 to give an answer.

Rather 28 , the king ordered, “You have three days’ grace. Any one who offers an answer will be handsomely awarded. Those who fail will be 29 .”

The time limit was due in the twinkling（闪烁）of an eye, yet the ministers were still at their wit’s end. At this time a child appeared who declared that he knew the answer. The king told his 30 ministers to go with the child for the measurement. To their 31 , the child refused the suggestion with a smile, “It is very easy. No 32 to go to the pond.” This made the king laugh 33 ,  “Alright, let us know what it is.” The child winked (眨眼) and said, “That 34 on the size of the bucket. If it is as big as the pond, there is one bucket of water; if it is half as big, two buckets; if one third as big, three buckets; if...” “Stop! That’s it. You’ve got the 35 .” The king was satisfied and the child was duly rewarded.

Why did the ministers feel it so different to settle the problem? Because they fell in a pitfall (陷阱), following a wrong way of thinking. People’s thinking often goes a habitual way — the beaten track of straightforwardness. 36  is a static (静态的) way presupposing every object definite and certain, i.e. the size of the pond and the bucket should be clearly 37 . If one of them is unknown, it will be difficult to do the measurement, let alone 38 . Why not change your mode of thought — from static to dynamic（动态的）, from concrete to 39  ? If you adopt an indirect way and try to find out the proportional relation between the pond and the bucket, you’ll get an answer — flexible yet 40 to solve the problem.

Sometimes to get out of the difficulty one must change one’s way of thinking, or simply change one’s approach towards a problem.

There are two types of twins; identical and non-identical twins. Identical twins are formed from a single egg in mother’s body which divides to from two separate babies. Identical twins look the same, and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs a the same time, both of which grow to form babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.
　　In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.
　　There is a third type of twins, but it is a very unusual one. Twins which are joined together at birth are known in western countries as Siamese twins.
【小题1】It is difficult to tell identical twins apart because _______.
