Read the following passage and decide whether the statements are true (T) or false (F).

We use many different energy sources for the sake of us. Energy sources are classified into two groups: non-renewable and renewable.

Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution.

On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like non-renewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the wind blows throughout the year. The five types include solar energy from the Sun; geothermal energy from heat within the Earth; hydroelectric energy from moving water; biogas from dead plants and microorganisms and finally, energy from the wind.

VIII. Read the passage and decide whether the statements are True (T) or False (F).

     There are many causes that lead to water pollution. One main cause of this issue is waste water coming from many factories and then being directly pulled out into water bodies, especially into rivers or seas without any treatment because this is the most convenient way of disposing waste water. Industrial waste consists of some kinds of chemical substances such as sulphur, which is harmful for marine life. Lead is known as the main reason for cancer disease. Cancer has become a popular disease in several communes which are called “cancer villages”. Another cause is the awareness of citizens, people always use water for many purposes and then they dump waste water or garbage directly into rivers, canals and ponds and so on. In 2004, because of a bird flu outbreak in Viet Nam, people threw poultry to water body that made water highly polluted.

1. Waste water from many factories which is dumped into water bodies directly causes water pollution.

2. Dumping waste directly into water is the most convenient way of disposing waste water.

3. Sulphur is believed the main reason for cancer.

4. Cancer villages occurred in 2004.

5. Due to lack of awareness, people poisoned water with dead poultry when there was a bird flu outbreak in 2004.

IX. Read the text carefully then decide whether the following statements are true (T) or false (F).

Many students listen to music while they are studying, and say that it helps them learn. Many parents and teachers say that music is just distracting, and that students are better studying in silence. Who is right? In a study, some scientists asked three groups of students to listen to a piece of music by Mozart or a relaxation tape for ten minutes, or just sit in silence for ten minutes. The students then did a ‘spatial reasoning’ test (a test about remembering shapes and imagining looking at objects from different directions), and the ones who had listened to the Mozart did better in the test. Taking part in musical activities and learning to play an instrument can improve verbal memory (the ability to remember words). The longer the training lasts, the better the improvement in the memory. So, there’s no excuse to give up the piano lessons! 

53. Many students think it’s helpful to listen to music when studying. 

54. Teachers say music helps students to better concentrate. 

55. The students who had listened to Mozart did better in the spatial reasoning test. 

56. Music training helps to improve memory

Listen again and decide whether the statements are true (T) or false (F).

BÀI 8. Read the passage, and then decide whether the statements are true (T) or false (F).

      Volunteering is one of the things that are very useful to you. To your future bosses, volunteer work shows that you are interested in both the world and your future.

      Although volunteer work does not bring you money, it gives you a time to learn social skills and make a difference in our community.
