TEXT 1
C
assava is the staple food of millions of people in Africa, Asia and South and Central America. Its swollen tuberous root can be boiled and mashed or grilled to produce a meal known as ‘farinha’ in Brazil and ‘garri’ in Nigeria, which can be cooked in small cakes. The root is also the source of manufactured commodity, tapioca. A small field planted with cassava can be insurance against famine, because the crop can be left in the ground for two or three years without deterioration of the tubers. But recent findings suggest that cassava may be responsible for birth defects.    
      It has other serious disadvantages. The tubers consist almost entirely of starch and are particularly low in protein, so dependence on cassava leads to serious malnutrition. To make matters worse, some varieties, when grown under certain conditions of soil and climate, develop a high acid content and become extremely poisonous to people and livestock if eaten raw. These tubers have to be well-prepared for consumption by prolonged and repeated boiling.
      The new danger has emerged over the past ten years in Nigeria. Doctors have begun to suspect that cassava, if eaten in large amounts during pregnancy, may cause deformities in the developing fetus; there to be a correlation between the eating of cassava by pregnant women and the occurrence of various kinds of brain or other neuronal malformations in their babies.

TEXT 2
Ultraviolet light means the invisible part of the spectrum beyond violet. This light has always been regarded as very useful because it is used to cure certain skin diseases, kill bacteria, detect counterfeit money, form vitamins, etc.
      Along with the increasingly extensive use of computers in financial activities, ultraviolet light has been widely applied by banks to identify the signatures of their customers in passbooks. When a customer opens a new account with a bank, the bank teller always asks him to sign on a card placed in the signature column of a passbook. When the card is removed, the trace of his signature will be left, this can be used to compare with the signature on the customer’s withdrawal slip under ultraviolet light.
      Ultraviolet light certainly has many practical applications, but it may also be harmful to human beings on some occasions. To everyone’s knowledge, the direct impact of the light on the eyes for an excessive length of time may blind a person.
      Even though it can cure skin diseases, it is also very harmful to the skin. A study just completed in the United States says that the light may cause skin cancer. The ultraviolet rays of the sun have been ranked as the third most dangerous cancer-causing agent after alcohol and tobacco.
      It is high time to warn sun-worshippers in the quest for a bronzed look to be careful of excessive and uncontrolled exposure to the sun.

a)      the use of ultraviolet light in business
b)      the effect of ultraviolet rays on human beings

TEXT 5

Nature VS Nurture 
People wondered for a long time how their personalities and behaviors are formed. Two distinct schools of thought on the matter have develop. The two approaches are very different from each other. The controversy is often referred to as nature and nurture.
Those who support the nature side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors. That our environment has little to do with our abilities, characteristics, and behavior is central to this theory.
Proponents of the nurture theory claim that our environment is more important than our biologically based instinct in determining how we will act. They see humans as beings whose behavior is almost completely shaped by their surroundings.
Neither of these theories can yet fully explain human behavior . In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes. That the controversy will continue for a long time is certain.
