Today,it is still possible to see what al-Jazari’s elephant clock looked like. A full-size working model is in Dubai’s Ibn Battuta Mall. There, every half hour, al-Jazari’s most amazing invention comes to life once again.
How Dose the Elephant Clock Work?
A bowl with a small hole floats(浮)in a water tank(水箱)inside the elephant’s body. As the bowl slowly sinks(下沉), it pulls a rope that moves a human figure. His moving pen shows the number of minutes past the hour.
Every half hour, the water bowl becomes full and sinks completely. This causes a ball to fall from the top of the clock. The movement of the ball causes a phoenix to move and make a sound.
The ball then drops out of a falcon’s mouth into the mouth of a Chinese dragon. The weight of the ball causes the dragon’s head to move down, and the dragon’s tail pulls the water bowl back up.
Finally, the ball drops out of the dragon’s mouth and into a vase. As the ball lands in the vase, the elephant driver moves and makes a sound. The cycle begins again until there are no more balls in the top of the clock.

Many scientists once believed that physical similarities between identical twins are genetic(基因的), while their personalities, intelligence, and other differences between them are an effect of their environment. Now scientists are discovering that the boundaries (界限) between genes and environment are not so clear.
Twins Jim Springer and Jim Lewis were adopted as babies and raised by different couples. When the Jims finally met at age 39, they discovered they had plenty in common. Both were six feet tall, 180 pounds. They had the same smile and the same voice. When scientist Thomas Bouchard Jr. invited the Jim twins to his lab, people there found it very hard to tell them apart.
But the similarities didn’t stop at the physical. They both had dogs named Toy. They had both married woman named Linda, and then their marriage broke up. They’d both been policemen, enjoyed music, and left love notes around the house for their wives. They had so much in common, it seemed unlikely these were just coincidences(巧合).
The Jim twins were just one of 137 sets of separated twins Bouchard tested. When they compared the twins’ IQ scores, Bouchard and his team reached a surprising conclusion( 结 论 ). They concluded that intelligence was mostly connected to genes rather than to training or education. It seemed the differences in family and environment had little effect.
However, genes can’t control everything, argues geneticist Danielle Reed, who also studies twins. Reed’s research shows that though nothing can truly change our DNA, environmental differences that a child experiences before birth and in their first year can sometimes affect the way the DNA behaves, making even identical twins into very different people. “What I like to say is that Mother Nature writes some things in pencil and some things in pen,” she explains. “Things written in pen you can’t change. That’s DNA. But things written in pencil you can.”
69. How many physical similarities between the Jim twins are mentioned?
A. 2.
B. 3.
C. 4.
D. 5.
70. What did Bouchard’s study find about the twins?
A. Each seemed to be as tall as their twin.
B. Each had the same hobby as their twins.
C. Each had almost the same ability as their twin.
D. Each had about the same IQ level as their twin.
71. What is Reed’s opinion about genes and environment?
A. Only DNA had an effect on our development.
B. Environment could possibly change some things about us.
C. There are so boundaries between genes and environment.
D. Environmental differences can sometimes change our DNA.
72. What is the passage mainly about?
A. The way the DNA behaves.
B. The similarities between the Jim twins.
C. The connection between intelligence and families.
D. The effects of genes on personality and intelligence.

The Value of Negative Results
We all avoid failure(失败), and most of us fear it. However, without failure, progress would be impossible. What does success usually come after? Failure. It seems that one cannot exist(存在)without the other.
Accepting failure is not easy for many, though. We are often unwilling to accept failure because our professional fame depends on success. 73___ In the past ten years, for example, some scientific magazines have published reports of failed tests. It is believed that scientists can learn from “negative(负面的)” results and that this can finally lead to positive results.
74___ The ABN AMRO bank started an Institute(机构)of Brilliant Failures to learn more about what works and what doesn’t in banking. Similarly, Eli Lilly and Company had failure parties to study the drugs(药物)that don’t work.
In fact, one of the business world’s most famous failures became one of its biggest successes, in part because the product’s makers learned from their mistakes. 75___ The product, though unique(独特的)at the time, was expensive and heavy; besides, some of its most important features(特点)didn’t work properly. As a result, it became one of Apple’s biggest failures, and in 1998, the company stopped selling it. However, Apple’s CEO, Steve Jobs, believed in the product and he began to find out ways of improving it. In time, this led to the production of the iPhone and the iPad, two of the company’s most successful products.
76___ Not only should we try to learn from it; if we want to succeed, we must also be persistent(执着的). Though Apple stopped selling the Newton in 1998, the first iPhone wasn’t available until 2007. It took a lot of research and hard work to go from the Apple Newton to iPhone, but in the end, the effort became successful.
All in all, there is a lot we can learn by studying mistakes. Perhaps the most important lesson is that failure and success are two sides of the same coin. 77___
A. One truly cannot exist without the other.
B. We are brave enough to face difficulties.
C In the early 1990s, Apple created a phone called the Apple Newton.
D. The business world already understands the value of negative results.
E. The Apple Newton has won popularity with people all over the world.
