Exercise 2: Read the passage then answer the questions that follow:
ΠScientists have established that influenza viruses taken from man can cause the disease in animals. In addition, man can catch the disease from animals. In fact, a great number of wild birds seem to carry the viruses without showing any evidences of illnesses. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom, a group that has been on the earth 100 million years and is able to carry the viruses without contracting the disease. There is even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.
 It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombination is a great variety of strains containing different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus from a lower animal to produce an entirely new spike. Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig, for example, to produce a new strain which is transmitted to man.

 	In sport the sexes are separate. Women and men do not run or swim in the same races. Women are not as strong as men. That at least is why people say. Women are called “the weaker sex”, or if men want to please them, “the fair sex”. But boys and girls are taught together at school and university. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men. A European woman can expect to live until the age of 74, a man only until he is 68. are women’s body really weaker?
	The fastest man can run a mile in under 4 minutes. The best woman needs 4.5 minutes. Women’s times are always slower than men’s, but some facts are surprising. Some of the fastest women swimmers today are teenage girls. One of them swam 400 meters in 4 minutes 21.2 seconds when she was only 16. the first “Tarzan” in films was an Olympic swimmer, Johnny Weissmuller. His fastest 400 meters was 4 minutes 59.1 seconds slower than a girl 50 years later! This does not mean that women are catching men up. Conditions are very different now, and sport is much more serious. It is so serious that some women athletes are given hormone injections. At the Olympics a doctor has to check whether the women athletes are really women or not. It seemed sad that sport has such problems. Life can be very complete when there are two separate sexes!

A. Boys and girls study separate everywhere.	B. Women do not run or swim in races with men.

3. “That at least what people say” means people _____.
A. say other things too.	B. do not say this much.
C. say this but may not think so.	D. only think this.
4. What problem does sport have?
A. Some women athletes are really men.
B. Some women athletes are given hormone injections.
C. Women do not run or swim in races with men.
D. It is difficult to check whether the women athletes are really women.
5. In this passage the author imply that______.
A. women are weaker than men, but faster.	B. women are slower than men, but stronger.
C. men are not always stronger and faster than women.	D. men are stronger and faster than women.
Ž	Although speech is the most advanced form of communication, there are many ways of communicating without using speech. Signals, signs, symbols, and gesture may be found very known culture. The main function of a signal is to impinge upon the environment in such a way that it attracts attention, as for example, the dots and dashes of telegraph circuit. Coded to refer to speech, the potential for communication is very great. Less adaptable to the codification of words, signals also contain meaning in and of themselves. A stop sign or a barber pole conveys meaning quickly and difficult to describe than either signals or signs because of their intricate relationship with the receiver’s cultural perceptions. In some cultures, applauding in a theatre provides performers with an auditory symbol of approval. Gestures such as waving and hand shaking also communicate certain cultural messages.
	Although signals, signs, symbols, and gestures are very useful, they do have a major disadvantage. They usually do not allow ideas to be shared without the sender being directly adjacent to the receiver. As a result, means of communication intended to be used for long distances and extended periods are based on speech. Radio, television, and the telephone are only a few.
1. Which of the following would be the best title for the passage?
A. Signals, Signs, and Symbols.	B. Gestures.	C. Communication.	D. Speech.
2. What does the author say about speech?
A. That it is the only true form of communication. B. That it is dependent upon the advances made by inventors.	
C. That it is necessary for communication to occur.	D. That it is the most advanced form of communication.
3. Applauding was cited as an example of _______.
A. a sign	B. a signal	C. a symbol	D. a gesture
4. Why were the telephone, radio and television invented?
A. Because people were unable to understand signals, signs, and symbols.
B. Because people wanted to communicate across long distances.
C. Because people believed that signals and symbols were obsolete.
D. Because people wanted new forms of communication.
5. It may be concluded from the passage that________.
A. signals, signs, symbols, and gestures are forms of communication.
B. symbols are very easy to define and interpret.
C. only some cultures have signals and symbols.
D. waving and handshaking are not related to culture.
	Hundreds of species of marine life manage to survive even in the darkest depth of the ocean. These tenants of the deep have involve some extremely ingenious devices for locating their food and enemies.
	Where the light is very dim, some of these deepwater species have developed enormous eyes with almost telescope lenses, very much like those of owls. Others, especially the fish that survive where there is no light at all, are quite blind but have developed long feelers that enable them to identify and collect stray bits of food that come within a considerable radius of them.
	Some inhabitants of the deep supply their own light. They have built-in torches that they can switch on and of depending on whether they are pursuing or being pursued.
	Some have regular lamps, spots of steady light, which spread a faint glow through the water around them. One deepwater squid can quirt a luminous that cousins nearer the surface to becloud and darken the water. It’s supposed that about half of the varieties of fish living in the dark depths of the ocean have some power of illumination.
