A farm planted levels or floors is called a vertical（垂直的）farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards，rather than outwards，it requires much less space than a conventional farm.
The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people，all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time，food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(杀虫剂) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space，therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course，not all food does well with this type of planting，but there are many crops that actually seem to do better.
In some climates，a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words，we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now，but they are a concept that will solve many of our problems in the future.According to the passage, a vertical farm________.

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime（消遣）, it also gives them time to eat more unhealthy food．What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.According to the text, what kind of children may eat more unhealthy food?
| A．Those who often take exercise. |
| B．Those who often watch television. |
| C．Those who often have meals at home. |
| D．Those who often walk to school. |
The author thinks that children are becoming overweight because .
| A．their parents often cook meals for them |
| B．they are too busy to go out and play |
| C．they can' t choose what to eat |
| D．there are too many fast food shops around |
The word "steering" underlined in the last sentence most probably means _______.
| A．forcing | B．guiding |
| C．driving | D．moving |
The main purpose of the text is to _________.
| A．tell a story | B．provide facts |
| C．give advice | D．compare opinions |
It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.Why was the bike so important to the couple?
| A．They used it for work and daily life. |
| B．It was their only possession. |
| C．It was a nice Kona 18 speed. |
| D．The man’s job was bike racing. |
We can infer from the text that ____________.
| A．the couple worked 60 hours a week. |
| B．people were busy before Christmas |
| C．the stranger brought over the bike |
| D．life was hard for the young family. |
What do the couple learn from their experience?
| A．Strangers are usually of little help. |
| B．One should take care of their bike. |
| C．News reports make people famous. |
| D．An act of kindness can mean a lot. |
Why play games? Because they are fun, and a lot more besides. Following the rules…planning your next move...acting as a team member…these are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作) .
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones. Which sharpens the hand-eye coordination（协调）needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it—some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to give people hope through soccer. He created a foundation(基金会) to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life. Through playing hide-and-seek, children are expected to learn to ________.
| A．be a team leader | B．obey the basic rules |

Eat like a king in the morning, a prince at noon, and a peasant at night. This saying is all about the importance of breakfast. And now scientists can tell us just why it’s so important. According to a study carried out at Imperial College London, UK, skipping the first meal of the day not only means you eat more at lunch, but also that your brain wants to find more unhealthy foods.
The study suggests that there is a special part of our brain called the orbitofrontal cortex (眶额皮层), which plays an important part in making choices about what we eat. It is used for identifying the taste of food, especially when skipping breakfast. It is more likely to target high-calorie foods when you’re on an empty stomach.
Scientists did an experiment on this. Dr Tony Goldstone from Imperial College London, scanned (扫描) the brains of 21 men and women, around the age of 25. On the first day, these people skipped breakfast before the scans. On the second day, they had cereal (谷物), bread and jam as breakfast. After the scan on both days, they had their lunch.
When the volunteers had skipped breakfast, they ate around 20 percent more at lunch, compared with days when they had eaten breakfast.Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods. “We believe that bit identifies the value of foods – how pleasant, how delicious something is,” Goldstone told The Guardian.From Paragraph 1, we learn that _____.
| A．scientists found out why eating breakfast is important |
| B．it’s easy to lose weight without breakfast |
| C．there’s no need to have good food for supper |
| D．eating breakfast makes your brain smarter |
