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 foods had lower IQs than those fed pasta , 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 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 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 test-the Wechsler Intelligence Scale 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. 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.

There are no exact differences between physics and other natural sciences because all sciences overlap .In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects. One major branch of physics deals with the states of matter--solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane. A branch of mechanics is statics ,the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism ,heat,light,and sound.From these branches of physics scientists find clues which have revealed the constructions of atoms and how the atoms react to various kinds of energy. _ is often called the basis of modern physics.Among the many subdivisions of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the "natural laws" of electricity to help in designing and electric generator . Physics is not exactly different from other natural sciences because _ . A) physics and other natural sciences have parts in common B) it is the scientific study of forces and qualities such as heat,light and sound C) it studies the ways in which forces and qualities affect other objects D) it is a part of other natural sciences

(Question)
One determined student stepped off the traditional job for blind people in China, and now challenges a new life at university in Britain. Being a message therapist is a perfect job for many people with a visual disability, but for Zheng Jianwei, it was far from enough. The 30-year-old former massage therapist gave up his hospital job in 2009to prepare for admission to graduate school. He took IELTS , the language-fluency test necessary for university admission in the UK, in 2012 and scored 6.5 points. He was the first blind examinee to take the IELTS in the Southeast Chinese region. After about four year's struggles, Zheng successfully gain an offer from the University of Essex in the United Kingdom and became a graduate student. However,Zheng's path to graduate school was not easy. "I can't take China's national entrance exam for graduate school, which doesn't provide study material for blind students," he says. He then turned to search for graduate school overseas. However, English became his nightmare. Zheng studied in special schools for visually challenged students since primary school, but foreign language was never a main subject. Before giving up his job and learning English again in 2009, Zheng only knew the alphabet, a few words and some basic expressions. "Learning English again in my late 20s is not easy," he says. It took him three years of intensive study to gain entrance to a graduate school overseas. Because of the lack of study material, Zheng needs to spend hours and days looking for textbooks for the visually disabled and copying them, while it may take only five minutes for a sighted person to order a plain English textbook from Amazon. In his parents' eyes, Zheng has been a sensible, independent and decisive man from a young age. Zheng made all the major decisions by himself, including studying abroad and choosing majors. "We just follow his decisions, " the mother says. Which of the following can match Zheng Jianwei's story? A) All mankind is created equal. B) Many hands make light work. C) Rome is not built in a day. D) Nothing is impossible when mind is set.
