For this task, you will write an essay in response to a question that asks you to state and support your opinion on a topic. Your essay will be scored on the quality of your writing, including how well you organize and develop your ideas and how well you use language to express your ideas. Typically, an effective essay will have a minimum of 300 words.<br>Read the question below and make any notes that will help you plan your response. Then begin writing your essay.<br>Do you agree or disagree with the following statement？<br>The government should require all young adults to perform. some kind of national service, such as military service or social work.<br>Use specific reasons and details to support your answer.

Question<br>The students discuss two solutions to the problem that affects them both. Describe the problem and the two solutions. Then state which of the two solutions you prefer and explain why.

The Writing section tests your ability to write essays in English similar to those that you would write in college courses.<br>During the test, you will write two essays. The integrated essay asks for your response to an academic reading passage and a lecture on the same topic. You may take notes as you read and listen, but notes are not graded. You may use your notes to write the essay. The lecture will be spoken, but the directions and the questions will be written. You will have 20 minutes to plan, write, and revise your response. Typically, a good essay for the integrated topic will require that you write 150-225 words.<br>The independent essay usually asks for your opinion about a familiar topic. You will have 30 minutes to plan, write, and revise your response. Typically, a good essay for the independent topic will require that you write 300-350 words.<br>A clock on the screen will show you how much time you have to complete each essay.<br>Integrated Essay "Primordial Soup"<br>You have 20 minutes to plan, write, and revise your response to a reading passage and a lecture on the same topic. First, read the passage and take notes. Then, listen to the lecture and take notes. Finally, write your response to the writing question. Typically, a good response will require that you write 150-225 words.<br>The origin of life was highly speculative until a graduate student at the University of Chicago, Stanley Miller designed and conducted an empirical research project under the guidance of his graduate advisor, Harold Urey. In this classic experiment, the researchers tried to simulate the chemical evolution process that generated life. Miller and Urey took a five-liter flask half filled with water and connected it with glass tubing to another flask into which they inserted tungsten electrodes. They then mixed methane, hydrogen, and ammonia into the water in the lower flask and heated it to induce evaporation, while at the same time subjecting it to continuous electrical charges that jumped across the space between the electrodes in the upper flask. The atmosphere was cooled again so that the water could condense and trickle back into the first flask in a continuous cycle. In this way, they sought to recreate the conditions in the early atmosphere of Earth, which they speculated was probably subjected to powerful electrical storms. In about an hour, the water turned orange. At the end of the first week, they observed that almost 15 percent of the carbon was converted into organic compounds. After several weeks, the liquid in the flask clouded and then gradually turned a dark brown. When they analyzed it, Miller and Urey found that it contained a large number of amino acids, which form. one of the basic structures of living organisms. They then hypothesized that the amino acids that they had created in the laboratory might be typical of the chemical mixture of the early oceans on Earth, and further, that additional amino acids could have been added to the mixture in the early oceans by carbon enriched meteorites or comets.<br>When the scientific results were popularized, the mixture became known as "primordial soup." However, much was still unknown about the process that caused the first cell to develop within the soup. The molecules produced were relatively simple organic molecules, not a complete living biochemical system. Nevertheless, the experiment established that natural processes could produce the building blocks of life without requiring life to synthesize them in the first place. The experiment served as inspiration for a large number of further investigations.<br>Model Test 6, Writing Section, Audio-09, Track 3<br>Now listen to a lecture on the same topic as the passage that you have just read.<br>Question<br>Summarize the main points in the reading passage, explaining how the lecture casts doubt on the ideas.

Do you agree or disagree with the following statement？<br>Because life is too complex nowadays, young people need the ability to plan and organize.<br>Use specific reasons and examples to support your answer.<br>300 WORDS
