Which is the world's highest, driest, coldest and windiest continent? Which is the only place on Earth not yet ruined, still untouched by the destructive hand of man? Australasia? Or "the ice", as Antarctica is referred to by its old friends? Of course, the former still has 5 large areas as yet untouched, but nothing like the huge virgin expanses of "the ice".

 Now, the virgin continent has become the source of yet another conflict between scientists and enviromentalists. The latter believe that 10 Antarctica must be maintained as such and that scientists should be careful not to leave behind anything that might damage the environment. Scientists say that limited local environmental impact has to be expected and accepted, because the continent is an important natural laboratory for estimating the effects humans have on the globe, even 15 functioning as a kind of early - warning system for the whole planet. There is a treaty designed to protect this continent which has only 8000 inhabitants and most of them not permanent, but contains 70% of the world's fresh water. Oil and minerals cannot be exploited, 20 but what controls are there on the growing number of scientists, explorers and even tourists?

1. According to the passage what is the main reason for the conflict between the scientists and the environmentalists?

A. The possible emvironmental damage 

B.  The use of Antarctica as a laboratory

C.Antarctica is becoming a tourist spot

D. Antarctica is being used as an early - warning system

2. What can be inferred from the passage?

A. Antarctica cannot be saved

B. Antarctica has too few inhabitants to worry about

C. Antarctica is worth saving

D. There is a treaty about Antarctica, so there is nothing to worry about

3. What is the synonym of " Permanent"?

A. Everlasting

B.  Unstable

C. Worthy

A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.

Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 43 to 50.

U.N. Abandons Treaty to Ban Cloning

U.N. diplomats abandoned efforts to draft a treaty that would outlaw human cloning. They will likely settle for a weaker statement, and won’t seek a widespread ban, officials said. The debate began when Italy introduced a document into the UN. to stop any attempt at cloning human life. The Belgians objected to the use of the term “human life” in the document, because they feared it would put a stop to all forms of human cloning.

[1] There is near universal support among the United Nations’ 191 members for a ban on

reproductive cloning-creating cloned babies. [2] Many countries have wrestled over whether to allow cloning for stem cell and other types of research. [3] Indeed, many researchers believe that stem cells could be used to repair nerve tissue or cure diseases, including Alzheimer’s. [4] Stem cells are taken from embryos and cloned, but extracting these cells kills the embryo. Opponents say that this is equal to murder.

Question 43: What is the main topic of this passage?

A. a disagreement on cloning

B. the definition of “life”

C. reasons why cloning should be banned

D. the arguments against cloning babies

Tương tự như vậy, ở đoạn 1 và 2 để có những nguyên nhân đi sau giải thích cho quan điểm của các quốc gia (because they feared it would put a stop to all forms of human cloning, stem cells could be used to repair nerve tissue or cure diseases, hay là this is equal to murder.)
