Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis(绿洲), from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.

When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.

Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.

Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________________.

Children brought up on healthy diets are more intelligent compared with their junk food eating partners, a new research suggests.  

Kids fed a diet packed high in fats, sugars, and processed(加工)  foods had lower IQs than those fed pasta(意大利面食), salads and fruit,  it was found.

The effect is so great that researchers from the University of Bristol said those children with a "healthier" diet may get an IQ improvement.

Scientists stressed good diet was essential in a child's early life as the brain grows at its fastest rate during the first three years of life.

This indicated head growth at this time is linked to intellectual ability and “it is possible that good nutrition(营养) during this period may encourage excellent brain growth” .

Scientists tracked the long term health and happiness of around 14,000 children born in 1991 and 1992 as part of the West Country's Avon Longitudinal(纵向的)Study of Parents and Children ( ALSPAC) .

Parents were questioned about the types and frequency of the food and drink their children consumed when they were three, four, seven and eight and a half years old. According to their different changing form, these children were marked and given grades which ranged from minus two for the most healthy to10 for the most unhealthy.

In the research, IQ was measured of 4,000 children when they were eight and half years old,  using a validated(经过认证的)test-the Wechsler Intelligence Scale(韦氏儿童智力量表) for Children.

The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half , whether the diet was improved after that age.

Every l point increase in dietary pattern score was associated with a l.67 fall in IQ.

1.Scientists stressed good diet was essential in a child’s early life because        .

A.the brain grows at its fastest rate during the first three years of life.

B.those children with a "healthier" diet must get an IQ improvement.

C.children brought up on healthy diets are less intelligent.

2.Which of the following is NOT true?

A.Those children with a "healthier" diet may get an IQ improvement.

B.Good nutrition at any stage may encourage excellent brain growth.

C.Scientists tracked the long term health and happiness of about 14,000 children.

D.Every l point increase in dietary pattern score was associated with a l.67 fall in IQ.

3.The results found if a child ate a leading processed food diet when he was 3, he would          

A.have a higher IQ

B.have a higher IQ as long as he improved his diet

C.have one IQ when he was 8

D.have a lower IQ whether he improved his diet

4.What is the best title of the passage?

A.Food for thought

B.What is healthy food?
