Do you agree or disagree with the following statement?
In twenty years there will be fewer cars in use than there are today.
Use specific reasons and examples to support your answer.
范文：
The Earth today faces many problems. Among these problems, the top three, in some people's perspective, are probably global warming, pollution and energy crisis. All three, if we really look into them, can be connected with the pervasive use of private cars. It is because of this, I agree with the statement that there will be fewer cars in twenty years comparing with today.
First of all, people will definitely use fewer cars. If we look at the global media, we are seeing an increasing consciousness on environmental problems. Be it the famous documentay by Al Gore, An Inconvenient Truth, or the "Earth One Hour" movement. They all indicate a global consensus: "We need to help the environment". So what's the easiest way to help? Using fewer cars. According to a survey conducted by the Ministry of Environmental Conservation in China, more than 40 percent of carbon dioxide produced by individuals are from private cars. If the trend of eco-friendly consciousness continues to grow in the next 20 years, people will, without a doubt, use fewer and fewer cars. So, in a nutshell, the first reason why people will drive less in twenty years is because they will be more environmentally-concerned.
Another key aspect is that, in twenty years, there will be fewer people in the world. If there are fewer people in the world, of course there will be fewer cars. If we are sensitive to global trends, we can see that a lot of countries in the world are facing a decrease in population. The biggest contributors to population growth, China and India, are also experiencing a decrease in the rate of population increase. In 20 years, I am confident that there will be, without a doubt, fewer people in the world. In this case, there will be a decrease in the needs of transportation. So, it is logical to assume that there will be fewer cars in the world twenty years from now.
A final argument I want to make is based on the ever developing technology. In the past twenty years, we have seen tremendous innovations taken place in the field of transportation. From high-speed trains to cars that run on electric, there is simply no telling what might happen twenty years from now. Considering how much we have achieved in the past twenty years, it is not so improbable for me to say that we might not even need cars in the near future. Who's to say that we won't be traveling on more efficient vehicles? Or maybe public transportation may become so convenient that we won't even consider using private transportation ever again? The fact is, we cannot deny these possibilities for they are very likely to happen. In this light, I am definitely supportive of the view that there will be fewer cars in the future.
From my arguments above, I think I am very optimistic about the future. I believe that, in twenty years, we will be living in a society with much fewer cars. And I am looking forward to that future.
Part Two科技带来的弊端
In terms of life quality, there is no question that technology has revolutionized our life. Yet we still cannot ignore the problems coming along with the progress. While we are enjoying the convenience of searching information online and the notifications from the calendar, we might receive an email accidentally sent by someone with evil intentions, which could cause some problems.
A ransomware, WannaCry2.0, has been passed around online recently. People who have received this email and clicked the link would find that their important documents stored in the computer are locked and they are blackmailed for large amounts of bitcoin, a kind of virtual currency. In order to get these documents back, people have no choice but to pay bitcoin or the real money. As a result, these victims could lose thousands of dollars, some of which would even lose all the important documents no matter they choose to pay or not.
Imagine that a to-be graduate who has already finished the final paper suddenly lose his paper, or a doctor who is going to do an operation suddenly lose all the information of his patients. You can understand how bad the consequence is caused by ransomwares such as WannaCry2.0.
Part Three托福综合写作：海洋生物灭绝
某一地点所有海洋生物在同一时间灭绝
阅读给出的三种观点：
1.海洋蒸发
2.致命病毒
e boom在食物链中积累
听力逐一反驳：
1.海洋蒸发应该还会有一些物种残存，但化石中并没有看到
2.单一的病毒一般只针对特定的物种或是两个相联系的物种进行攻击，不可能同时灭绝这么多生物
3.化石上有些生物是食草的，不会受到毒素在小鱼体内积累的影响
版本二:
主题
Topic：发现了一大批ocean animals死在了一起 有几个theories
R&L对照
Reading:
1、原来这块地方是个lagoon，因为地震啥的.会堵塞河口，动物就被渴死了;
2、一些virus导致他们死了，比如现在就有个virus影响了dolphine;
3、algae会分泌一些toxic，如果很多fish吃了就会发生toxic concentration，一些位于食物链高级的动物就会死。
Lecture:反驳
1、如果这个地儿的ocean water evaporate还会留下mineral，但是并没有发现mineral;
2、一个virus只能影响一个species，少数情况下它能影响两个closely related species，但是不可能同时影响mammals和fish species;
3、plant-eating species不会受影响，这些fossils里还发现了large mammals他们主要吃植物，那他们体内的toxic应该不足以导致他们死。
