According to experts, the advantage of modified food is that it helps in preventing the occurrence of allergies and also has a long shelf life. However, a major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantages. If you are also confused about the consumption of genetically modified food, read through the pros and cons given below and decide for yourself.
Advantages of Genetically Modified Foods
●One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseases. Certain foods cause allergy to people. Their genetic modification alters the DNA system of these foods, thereby making them non-allergic.
●Another major advantage of such type of foods is that they grow faster than their traditionally grown counterparts. As a result, there is greater productivity and more food.
●A person need not bother about any additional costs, such as buying chemicals and pesticides, when it comes to genetically engineered food. The food is naturally pest-resistant.
●Farming these foods can be a great way to fight world hunger. Since these crops grow faster or more effectively, increased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions.
●The increased shelf life of these food products helps in reducing the quantity of rotten food.
Disadvantages of Genetically Modified Foods
●The biggest disadvantage of genetically modified food is that they have harmful effects on the human body. The consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics.
●Chances of developing cancer are high in people who regularly consume engineered food.
●Since it is an unnatural way of producing foods, there is an increased health hazard such as allergens, transfer of antibiotic resistance markers and unknown effects.
●Since the production of engineered food involves infusing animal genes in the crops and tampering with nature, it might not be good for consumption in the long run.
How does genetically modified food control the occurrence of certain diseases__1__
A. By cross-pollinating.
B. By conventional crossbreeding.

A. Yes, they need to. Because the food is not resist to pests.
B. No, they don’t need to. Because the food is naturally pest-resistant.
C. No, they don’t need to. Because the chemicals and pesticides are provided by the government.
3. Which statement is not the advantage of genetically modified food__3__
A. It may have harmful effects on human body.
B. Genetically modified food grows faster than their traditionally grown counterparts.
C. Farming genetically modified food can help fight world hunger.

Babies who are breast-fed may be more likely to be successful in life, a new study published Tuesday suggests. The study followed more than 3,000 babies into adulthood in Brazil. The researchers found those who were breast-fed scored slightly higher in intelligence tests in their 30s, stayed in school longer and earned more money than those who were given formula（配方奶粉）.
“Breast-feeding not only has short-term benefits, but also breast-feeding has long-term benefits, ” says Bernardo Lessa Horta of the Federal University of Pelotas in Brazil, who led the study being published in The Lancet Global Health.
Doctors have long known that breast-feeding can be good for a baby.s health. This is especially true in poor countries, where water can be contaminated. For instance, a baby given formula in developing countries is 14 times more likely to die in the first six months than one who.s breast-fed. In the U.S., some research has suggested that breast-feeding may raise a baby.s IQ（智商）by a few points. But a recent study with siblings（兄弟姐妹）found little advantage to breast-feeding.
Horta says these previous studies didn.t follow children into adulthood to see if breast-feeding had long-term effects. So Horta analyzed data collected from 3,493 volunteers he and his colleagues have been following since birth. They are now in their 30s. First, the researchers gave the subjects IQ tests. Those who were breast-fed for 12 months or more had IQ test scores that were 3.76 points higher than those who were breast-fed for less than one month, the team found.
When Horta and his colleagues looked at how much education the subjects had gotten and how much money they were making, they also found a clear difference: Those who were breast-fed the longest stayed in school for about an extra year and had monthly salaries that were about a third higher.
1. From the passage, we learn that Horta __1__.
A. is from Brazil
B. conducts his research in the U.S.
C. has 30 researchers on his team
2. Which of the following about those who were breast-fed is NOT mentioned__2__

3. Which of the following is TRUE__3__

B. Horta is concerned with water contamination in poor countries.
C. Horta.s research project lasted about 30 years
4. The word contaminated in Paragraph 3 is closest in meaning to __4__.
A. finished
B. interested
C. polluted
5. Which of the following is an appropriate title for this passage__5__
A. Researchers Have Pointed Out the Disadvantages of Breast-feeding
B. Researchers Have Found Out the Shortcomings of Formula
C. Breast-feeding Improves Chances of Success__3__(完形填空)
