Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.

A.Popeye the Sailor |
B.The Truth About Spinach |
C.A Mistake with Numbers |
D.Folic Acid Makes You Strong |
A.People liked folic acid. |

试题分析:从二十世纪三十年代动画片《大力水手》的播映以来,菠菜成了人们餐桌上必不可少的一道菜,人们都认为菠菜所含的铁会赋予人力量。事实上,菠菜里含的铁并不比别的蔬菜多,只是菠菜中的叶酸才能够使人身体强壮,在本文中作者揭示了这一事实。
小题1:主旨大意题。文章开头提出《大力水手》的播映使得人们一致认为菠菜会给人神奇的力量,然后下文指出this is not true.,接下来作者讲述了有关菠菜的事实,由此可知文章中心内容是纠正人们对于菠菜错误的认识,故答案选B。
小题2:推理判断题。动画片中的大力水手吃了菠菜后会力大无穷,看过这个动画片的人们也把菠菜当成了他们餐桌上一道必不可少的菜,由此推断人们认为菠菜真的会让他们身体强壮,所以选D。
小题3:细节理解题。根据文章第三段This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.可知研究人员提出了菠菜比其他绿色蔬菜含铁更多的观点,答案选D。
小题4:细节理解题。根据文章末段It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along. 可知叶酸会给人提供能量,或许大力水手的力量就是由此而来的,故答案选C。

Anyone who is a creative genius will tell you that creativity is very much like a muscle that needs to be developed. If you don’t learn how to develop creative thinking, this skill, just like a muscle, will become poor and useless. On the other hand, keep working at it, and this skill will soon be ready for action whenever you need it. So how do you develop your own personal style of creative thinking?
You should realize that your brain has a greater capacity (容量) and a higher speed than the world’s biggest and fastest computer. So it’s important to get as much information as you can every day. Read, watch and listen to everything around you —good and bad. The more you know, the more you’ll want to know, and the more your brain will be exercised.
Try something new every day and let your experiences show you more about the world and people around you. You need to step out of your comfort zone (舒适地带) more and more each day.
Follow these suggestions, and begin thinking beyond your "limits" from today. You’ll soon have a life full of interesting and exciting adventures. Who knows, your idea might be the next great idea to change the world.
小题1:Most people can’t be creative geniuses because they _______.
A.don’t have great ideas |
B.don’t want to develop their ideas |
C.are too shy to talk about their ideas |
D.don’t believe they can be |
A.creative thinking | B.the muscle | C.personal style | D.great capacity |
A.No computer can store as much information as human’s brain. |
B.It is not necessary to remember everything around you. |
C.Try something new, as long as you are comfortable with it. |
D.It is harder to exercise the brain than the muscles |
A.how they can learn from creative geniuses |
B.about ways to develop their creative thinking |

The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎动物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?
小题1:We can learn from the passage that seahorses _______.
A.are beautiful, and live on seaweed |
B.are as big as regular horses |
C.live near deep channels |
D.like to be alone |
A.male seahorses lay eggs |
B.seahorses mate in spring or autumn |
C.male seahorses give birth to babies |
D.seahorses mate in warmer waters at night |
A.Their fast speed of swimming. |
B.Their ability to change colours. |
C.Their unique eyes. |
D.Their strong tails. |
A.Eat. | B.Hold. | C.Make. | D.Handle. |
However, what most parents fail to see is that the best early education they can give their children is usually very cheap.
Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize, though, is that today’s children lack self-respect and self-confidence.
The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.
Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them,tying to fix them ,your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.

We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (显示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快门). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.
It took all of our learning and all of our thinking to realize something so simple, so clear, and yet so tall.
And I wish your pocket were tall enough to hold such a perfect invention!

A.humorous | B.objective | C.scientific | D.serious |
The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could lead to batteries that use water instead of poisonous substances.
The scientists made the discovery when they were investigating what happens when tap water is forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length of the tube. To produce a larger electric current, the team tried forcing water through a glass water filter(滤水器)that contained thousands of narrow channels lined up side by side. “When we took a syringe(注射器)of water and squeezed it through the filter, we got enough power to light a light bulb,” said Larry Kostiuk of the University of Alberta in Canada. “The harder you push the syringe, the more electric current you get.”
The current is produced because of an effect in the glass tubes. When they are filled with water, positively charged ions(阳离子)fixed in the tubes are washed away, leaving a slight negative charge on the glass surface. When water is then forced along the tube, the surface repels negatively charged ions in the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current.
According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way. “The last time someone came up with a way of generating electricity was Michael Faraday in 1839,” he said. “So this is the first new way of generating electricity in 160 years, which is why we are so excited about it.”
Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but admitted that the engineering challenges might make other applications more realistic. “You’d need to be sure it wouldn’t leak, and you’d need to make sure it wouldn’t freeze,” he said.
More likely would be to install the electricity-generating devices where water is already being pumped, such as at city water filtration sites, he said. “It could compete with wind and solar power,” he added.

A.They were the first to find a new way to produce electricity. |
B.They could make an electric current to light a light bulb. |
C.Their discovery could be used to invent water batteries. |
D.Their discovery was made 160 years earlier than Faraday’s. |
A.They must be used to power mobile phones and calculators. |
B.They have some possible disadvantages like water leaking. |
C.They would be needed greatly at city water filtration sites. |
