The human foot contains twenty muscles. This means that there is a lot that can go wrong when you run. Most sports have some kind of running or jumping So experts at many shoe companies work hard to design good sport shoes. First, a designer enters a plan for a shoe into a computer .Engineers then improve the design. A second computer designs a model for the shoe. Then a few pairs are made. Next, the shoe is tested. Different kinds of sports shoes are made for different uses. Some are made to help marathon runners save energy during a race. Some are made for the stop-and-go kind of running tennis players. But all sport shoes have one thing in common: they are designed to help people's feet comfortable during sports. Today, nearly every sport has its own special shoe designed for just the kind of running that sport needs.

Please answer this: Write a multi-choice question for the following article: Article: I recently ran into a friend I hadn't seen for a long while.Our conversation was lively and full of news from both sides.Before we parted she said,"You'll have to drop in sometime." I immediately sensed that if I simply "dropped in'' I would take my friend by surprise,and I would be discouraged by the image of her standing in her doorway,staring at me,and asking,"Oh,err ...what brings you here?" Whatever happened to the unannounced drop-in visit? When I was growing up in the 1960s, it seemed that people - mostly relatives, but also friends - were always _ . My parents would put coffee on,and my mom would find something in the kitchen to serve along with it.Then the conversation would begin...The neighbor lady,a worrier,was unloading her sadness while my mom quietly listened.The Irish man next door had such an accent that I remember asking what language he spoke.My Polish relatives arrived in packs...But I never heard my parents say anything like "We weren't expecting you'' or "This isn't a good time."Drop-in visitors had a certain right of way and became No.1. What happened to such visits? Actually I know the answer.Times have changed.Everybody gets busy with work.There is no longer a stay-at-home mom keeping a pot of hot coffee or tea ready throughout the day for a surprise guest.Exploding malls and stores are now replacing homes as a central form of entertainment. Just the other day a former student of mine showed up."I'm sorry for the surprise visit."my student began."I just wanted to see if you still lived here.I'll only stay a minute."My response was immediate." No, you won't," I said."Just come in, sit, have coffee, and we'll talk.'' I had nothing in the kitchen but we ordered pizza.And we had a lovely time.I have tried to keep the drop-in tradition alive though it takes some effort.

Problem: Write a multi-choice question for the following article: Article: Do lobsters, crabs and other crustaceans feel pain? We certainly act as if they don't.Most chefs cook lobsters and crabs alive, usually by dumping them in boiling water.Along with melted butter.That's the appeal of crustaceans-there's no fresher food.We may feel a bit of guilt, or maybe just discomfort, when we hear the creatures rattling around the inside of the pot as the water boils.But that feeling usually _ for lobster lovers by the time we crack open a claw and dig out the delicious meat.We wouldn't dream of doing the same thing to a live chicken or pig which are dead well before die cooking process begins, but those crustaceans are different.They don't even feel pain.Right? Actually, they just might.That's the conclusion of a new study published in the Journal of Experimental Biology.Robert Elwood and Barry Magee of Queen's University in Belfast examined the reaction of common shore crabs to small electrical shocks. Ninety crabs were placed in a brightly lit area and were given the choice of moving to one of two dark shelters.(Shore crabs like to hide in dark, tight spaces.) Once they'd made their choice, the crabs in one of the shelters were exposed to an electric shock.After a rest period, the crabs were returned to the lit tank.Most of the crabs went back into the dark shelters, and then the same crabs were given another electric shock.When they were placed back into the lit tank for the third time, the majority of the shocked crabs instead went to the other dark shelter, avoiding the one where they had repeatedly been shocked. As Elwood put it, the crabs' choice indicated they wanted to escape the shocks: Having experienced two rounds of shocks, the crabs learned to avoid the shelter where they received the shock. They were willing to give up their hideaway in order to avoid the source of their probable pain.

A: Question: What does Robert Elwood and Barry Magee's new study prove?Options:A It is hard to tell whether a voiceless shore crab is feeling pain or not.B Shore crabs react to electric shocks and seemingly feel pain.C Shore crabs prefer a dark, tight shelter as their-habitat.D Bright light causes discomfort to crustaceans.Answer:B

When he was travelling in Scotland, he decided to visit Loch Ness, the famous lake where people say there is a monster. But while he was going across the lake in a boat, his bag fell into the water. In the bag were his passport, car keys, pen, and all his money. Loch Ness is 150 metres deep, so he didn't expect to see the bag again! Fourteen years later, in 1994, some scientists decided to explore the lake. They looked for the Loch Ness monster. Suddenly one of them saw something black in the water. They carefully went nearer. They thought the black thing was the monster. They went nearer and nearer. It was a bag. They took the bag out of the lake. They found that the photo on the passport was still clear.
