Task 1The line graph illustrates not only how much energy was spent on fuel industry from 1980 to 2008 but also the amount of them will be consumed in a period of 22 years between 2008 and 2030 in the USA.In the first year, 1980, the amount of petrol and oil and natural gas was used for fuel relatively stood at 35 and 20 quadrillion. After that, they both experienced a decline of 5 quadrillion in 1985. Finally they have met a considerable increase and are expected grow up by about 15 quadrillion in 2030 though there will be some minor fluctuations. The three different kinds of natural energy which are nuclear, solar/wind and hydropower are sharing the similar consumed trend, they all started at below 5 quadrillion in 1980 then reached a plateau till 2008 and are predicted to not have many fluctuations in the future. Lastly, the amount of coal, which was just around 15 quadrillion at first, then went up to 23 quadrillion in 1995. Afterward, it has still increased and predictions show that it will reach 30 quadrillion in 2030.Overall, it can be seen from the graph, the petrol and oil energy has the highest amount consumed, 10 times greater than hydropower, which stands at last position.Good, 6.5-7.0 Task 2In modern world, learning new languages is very important and people have numerous options to choose to study. However, we can't deny fact that some languages are becoming extinct yearly. While some people have strong view that it will be easier when these unpopular languages die out, I believe that the loss of languages will cause several serious problems and I largely disagree with that idea.Comment by Admin: cannotFirstly, the extinction of languages can brings about the disappearance of cultural and diversity of language itself. Different countries have different languages, each has its own interest and it reflects the cultural of civilization so losing languages can result in a terrible part of a nation's history. Secondly, many of the traditional myths are written or documented in the minority languages, so if they die out, then the culture would also be lost. That is to say, a great number of old stories were written in ancient languages and most of them can only be understood by a small group of elders who are called "last speakers" of an extinct language.Comment by Admin: sComment by Admin: hy din t li cho gn hn v trnh dung t terrible nhComment by Admin: legends nh, myth cng c 1 ngha na l s hiu nhm, nn nu dung y c th gy confusedComment by Admin: lp t. disappear, diminishAnother point is that, linguistic is an art, a science that related directly to the diversity of language, but now it is no longer an interesting subject since there are just a few languages left in the world. For instance, young people nowadays have none of attention in researching the beauty of ancient languages as well as saving them for the future. Moreover, for the most of younger, the everyday language is English because there are not any unpopular languages left available for them.Comment by Admin: preserve cng dcComment by Admin: din t hi ti ngha nhTo conclude, other people consider studying fewer languages as uncomplicated task; however certain languages resemble historical value, and should be given importance.I believe that in the future, more and more minority languages will be reserved as well as passed on to the next generation.Comment by Admin: contain, conveyComment by Admin: consideration cng c6.5Vocab: good except for some minor errorsStructure: goodIdea: goodGrammar: good
