Guide to answer
A-2 B-1 C-3
Can we live there?
Traveling to Mars could become a reality sooner than you think. Scientists are planning to send humans (not animals) to Mars in the near future. They believe that is the only way to find out if there is life, or even life, on this planet. They will explore the possibility of living there. So people can go there to live one day!
Can we live longer?
Scientists say that in the future people will live longer. Untreatable diseases will be cured and “bad” genes will be able to be replaced. With a healthier lifestyle and better medical care the average person will live to 100 instead of 70 (in men) or 75 (in women). Anti-aging drugs will also be invented to help people live longer.
Predicting future houses
Future homes will be located on the sea, in the air, and underground. These types of homes will feature innovative energy-saving equipment such as solar panels, solar windows and smart home technology. Homes of the future will take advantage of robots to do household chores like cleaning, cooking, washing and organizing things for their owners.

3. Practice Task 1
Read the passage below and decide whether the statements are TRUE or FALSE?
Inventions That Changes Our World
People have been inventing things for years. Paper was invented about 2,000 years ago. The wheel was invented more than 5,000 years ago. What would life be like without paper to write on or bikes to ride? Those inventions have made life easier.
The Wright Brothers invented the first airplane in December 1903. That makes 2003 the 100th anniversary! Before the airplane was invented, most people traveled by cars, boats, and trains. Today, airplanes help people travel faster. How do airplanes help you?
Alexander Graham Bell invented the telephone in 1876. Before the telephone was invented, people kept in touch by writing letters or talking in person. Today the phone makes it easier for people to talk to one another. How do phones help you?
The first four-wheeled gas-powered car was invented by Karl Benz in 1891. Before people had cars, they couldn’t travel easily. They walked or rode horses for short trips. They took trains or boats for long trips. Today cars are one of the main ways people travel. How do cars help you?
People worked for years to make the first computer. It was built in 1946. The first computer was called ENIAC. Today computers are an important part of many people’s lives. People use computers as tools to write, get information, and much more. How do computers help you?
Question 1: The wheel was invented more than 5 thousands years ago.
Question 2: Before the airplane was invented, people traveled around on foot.
Question 3: Alexander Graham Bell invented the telephone in 1876.
Question 4: Before the invention of automobiles, people walked or rode horses for long trips.

4. Practice Task 2
Choose the letter A, B, C or D to answer these following questions
The history of the computer in the twentieth century is one of dramatic adaptation and expansion. The computer had modest beginnings in areas where it was used as a specialist tool. The first electronic computer was built in the 1930s and was solely for use of undergraduate students in Iowa State University to handle mathematical computations in nuclear physics. In World War II, computers were developed in order to wage counter espionage and break codes used by the enemy. In the post-war years the scope of computers was expanded to include the military industrial complex and academia. Obviously people needed to travel around these institutions and so there was a need for early network tools. In the 1960’s an early version of the Internet, ARPPANET was used in computers were starting to change our lifestyle, the way we do business and many style things (Elliot, 1994) and by the late 1980s, networks were expanding to embrace sections of the general public. The internet was born.
