【題目】People have been making and flying kites for about 2,000 years. 【1】Some historians believe it the ancient Chinese may have started kite flying 2000 years ago. It is still a popular hobby in China, Japan and Korea and in other countries of the Far East where beautifully decorated appear in different colors.

It was a very dangerous experiment that you shouldn't copy.

Kites were also used to develop airplanes. The Wright Brothers experimented with kites before they flew the first airplane. 【5】 In World War I the Germans developed a large kite that could transport people to a submarine. Kites were also used to carry radio signals over long distances.

【題目】根據(jù)短文內(nèi)容的理解, 選擇正確答案。 Each year, we are exposed to ten thousand ads on average. They try to sell us their products by using beautiful art, videos, images or slogans that are catchy. The most famous companies have highly popular logos that can be recognized by almost everybody. For those of you who have seen the movie Finding Forrester, there is that scene where Jamal walks up to some guy with a BMW and asks him what the car logo means. The man did not know the answer and since that day, whenever I see a famous company logo I try to find the meaning of it.
Many think the horse on the Ferrari logo represents the horsepower of the cars they manufacture. The story behind it is far more interesting. During World War I, a pilot, Count Francesco Baracca, painted the horse on his airplane to bring him luck. He had it on his plane because it was the logo of his squadron（空軍中隊）. Baracca's mother then convinced Enzo Ferrari to put the logo on his racing cars in the early 1930's to bring good luck to the drivers. The logo then stayed the same ever since. The yellow on the background represents the birthplace of Enzo Ferrari.
Starbucks started in 1971, in Seattle. The mermaid（美人魚）represented on the logo is now known by any coffee drinker. It is a mythological sea creature with the look of a female, the only difference being that they have a tail of a fish. The reason why Starbucks incorporated one in their company logo is that it was believed that mermaids used to sing to sailors in order to make them walk away from their ship or to ground their ships. In the 1500s, spices, tea and coffee were popular merchandise to trade. So the mermaid in the logo of Starbucks is the one that "brings" coffee and tea to the stores.
（1）The writer became interested in logos of some famous brands after _______.
A.he watched an attractive movie
B.he saw a scene in a movie
C.he walked up to some guy with a BMW
D.he noticed some famous logos
（2）Many companies use logos because _________.
A.people enjoy beautiful logos
B.people are more likely to buy their products
C.people can recognize the products more easily
D.people are interested in the meanings of the logos
（3）Which of the following is true according to Paragraph3?
A.Starbucks was once a company trading spices, tea and coffee.
B.Hearing mermaids sing, sailors would know the right direction.
C.Starbucks has a history of more than five hundred years.
D.The logo of Starbucks is believed to make the business years.
（4）The underlined word "incorporated" in the third paragraph probably means _____.
A.included
B.abandoned
C.corrected
D.designed

【題目】根據(jù)短文理解，選擇正確答案。
Next time you raise an eyebrow at the views of your partner, friend, sibling (兄弟姐妹) or colleague, remember they could be helping to make you smarter.
New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members, bright mates and intellectually stretching (拉伸) careers.
The study challenges the commonly held belief that intelligence is static by the age of about 18. Current scientific consensus suggests that intelligence is controlled by genes, with environmental factors such as schooling and nutrition playing a partial role up to this age. After this point, IQ scores stabilize (穩(wěn)定).
But James Flynn, professor of political studies and psychology at the University of Otago in New Zealand, argues that people can “upgrade” their own intelligence throughout their lives. He believes intellectual stimulation (刺激) from others is crucial as the “brain seems to be rather like a muscle – the more you use it, the stronger it gets”. However, the opposite is also true – so people sharing a home or workplace with those who are intellectually challenged risk seeing their IQ levels fall as a result.
He found the “understanding quality” of a family changes the IQs of all members, especially children. It can “l(fā)ift” or hold back, depending on the “gap between their brightness and that of their siblings and parents”. A bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage, compared to a similar child with equally bright siblings. However, children with a low IQ could gain six to eight points by having brighter siblings and special educational treatment to help pull them up.
Professor Flynn also concluded that although genetics and early life experiences determine about 80 percent of intelligence, the remaining 20 percent is linked to lifestyle. This means that people can raise their IQ, or allow it to fall, by ten points or more. Therefore, the best way to boost IQ level is to mix with bright friends, find an intellectually challenging job and marry someone cleverer.
（1）We can learn from the passage that ____.
A.as the age grows, you will become smarter
B.a 35-year-old man is surely smarter than himself at the age of 18
C.you will be smarter if you have a partner, a friend or a sibling
D.after 18, you still have the possibility to become smarter
（2）The underlined word “static” in the 3rd paragraph probably means ____.
A.unstable
B.fixed
C.varied
D.repeated
（3）James Flynn holds the belief that ____.
A.intellectual stimulation from others makes the brain work better
B.people should avoid working with those intellectually challenged
C.one's IQ could be held back if he has bright brothers or sisters
D.the IQ of children is least influenced by the understanding level of a family
（4）What's the best title for the passage?
A.Genetics Determines Intelligence.
B.Watch Out for Intelligence Falling.
C.Bright Siblings Make You Smarter.
D.Brain Is Like Muscle.
