It is still necessary for people to travel to other places to learn about other cultures. Nowadays, the increasing resources, such as books and films, make us easier get in touch with another culture. Some people think they can learn enough cultural knowledge without traveling. I tend to disagree with this idea since traveling can give us detailed experience. As the Internet development, we can acquire a huge variety of information about other countries. We have access to local history records from professional websites. Many documentaries spread local people’s habits and customs. For example, I have never been to American, but I know the super bowl is the most important game and most American celebrate it together as a festival. Obviously, reading or watching films is more convenient than traveling since we do not need to spend a lot of time on booking hotels and applying for visas. Moreover, virtual reality appears and gives us more realistic feeling. However, traveling is unreplaceable. It is a lifestyle. That means，we cannot live a local life without being there. From tasting local specific, we can learn about local food culture. We can have a deep understanding of their belief by taking part in religious activities. Face-to-face communication gives us chances to make friends with locals. In addition, there is always a gap between network images and the reality. we only can feel the greatness of historical buildings when we stand in front of them. For instance, people cannot feel how long the Great wall is except for climbing it. In summary, traveling is the best way to learn the culture and it can build close friendships between people from different areas. Others are just supplements.

It is still necessary to use animals for food, clothing or medical research. Nowadays, animals are widely used in many areas. Some people think it will be unnecessary to use them in the near future. I tend to disagree with this idea since although animals can be replaced by many new technologies in the certain field, such as clothing, humans still need to use animals for food or medical research. We do find a lot of alternatives to animals. Some scientists use soybeans to create new types of food which are tasted like meat. So, many vegetarians who eat these foods can acquire enough protein in daily life. Meanwhile, a few animal protection institutions claim vegetarian diets can be as healthy as normal ones. Researchers from Peking university tried to find a way to use simulation in computers to replace drug tests on animals. It true that some drug tests are really cruel, and we have no moral right to take animals’ lives. Moreover, using wild animals’ fur to produce clothes is banned by most countries. However, it is nearly impossible to replace animals everywhere. Meat eaters argue that it is really hard to have a balanced diet without meat because meat analogs are usually expensive and hard to find in markets. Meat is traditional food in many religions and countries. It is unfair to ask some people to give up their customs. In addition, medical tests on animals are more efficient and convenient. Some useful drug cannot be waited for a long experiment process, because they are related to many patients’ lives. At that time, sacrificing animals is necessary. In summary, we need to respect animals’ right and reduce to use them for our vanity, while we cannot avoid to utilize them because of cultural or scientific reasons.

Students can learn more from lessons. Nowadays, students can acquire knowledge not only from classrooms but also from the Internet or television. Some people still believe that students can learn more from lessons. I completely agree with this opinion because the term education system can provide students with qualified leaning experience and meaningful activities. Students can make more progress from a mature education system. In school, structured courses are able to help students to build a good academic foundation since these courses are usually well-designed by experts and professors from many fields and have been tested by many learners. Students also do plenty of science experiments in labs that can improve their understanding of theory learned in books. However, it is hard to get laboratory equipment at home. Moreover, teachers can give students useful advice based on different students’ study experience and family background. Students can join in many interesting activities in different lessons. In many science classes, such as chemistry, physics, and math, students are asked to take part in group discussion to explore new knowledge together. By learning that, students can enhance their communication ability. In law class, students need to do a presentation of their learning results. They need to face audiences to give a speech and prepare a PowerPoint by searching many materials before that. In contrast, children who are homeschooled and only learn from websites or TV programs usually do not have these chances to improve themselves. In summary, students can study efficiently with their teachers and classmates. Furthermore，the Internet cannot teach students effectively because of lack of communication and interaction. Most students should go to school to get an education and the internet and television can be good supplements.

Parents should not spend more time with their children helping them with their homework. Nowadays, there are some parents offer to assist with the homework of their children. Some people think it is necessary and should be consumed more time. I strongly believe that this idea is largely detrimental to develop children independent learning ability and parent should do something more meaningful with their children in their spare time.   Children that accomplish their homework with their parents' help is a negative thing that affects their personal development. When children do their homework with their parents, they may lose a chance to review what they learned in the classroom by themselves. So they hardly acquire a deep understanding. In this studying mode, children are not able to create their own thoughts which are important for them when they access in university. So parents' help is negative in short and long run.   In addition, parents are mostly responsible for ensuring that children grow up in a healthy and happy environment. No one can replace parents to take care of their children's mood and eating. In school, it hard for teachers to take care of every students' feeling and nutrition. Otherwise, it is teachers' responsibility that gives every students' enough academic guidance. When children feel sad, parents need to use their time to talk with them because parents are in the best position to help them. In summary, Children can be benefited by maintaining their independence in learning.  Moreover, sparing time between parents and children is limited since parents have their jobs and children need to go to school in the daytime. Parents' irreplaceable role is not mean they should replace their children’s teachers.

The reasons why I choose to buy a electric vehicle Nowadays, there are lots of concerns about electric vehicles. Some people think that the petrol-powered cars should be totally replaced by them. This argument may be true. EV is better for the environment.By choosing to drive an EV you are helping to reduce harmful air pollution from exhaust emissions. An EV has zero exhaust emissions. If you use renewable energy to recharge your EV, you can reduce your greenhouse gas emissions even further. Also, the electric car industry is growing fast. As a result of it, EV has the ability meet any kind of transport needed.Electric engines have a higher speed compared with gas engines which make transport is more efficient. Moreover, the new type of battery which can store more energy makes it possible to support long-distance trips. For instance, the newest generation electric car from Tesla company can go from 0 to 60 miles per hours in just six seconds and has a range of 215 miles, which should accommodate most people's commutes. On the other hand, there are some aspects of this argument. Batteries that power these cars are a costly affair. The promising and long-lasting lithium-ion batteries cost about US5,000 each, which for the most part make these cars expensive. And if the batteries last only about 4 years, they could add to the maintenance costs. Also recharging of batteries often takes about 3 hours, which nowhere matches the efficiency of a gas refuel.However, these issues can be addressed strategically within the technology development. In summary, anything which encourages EV industry benefits society environmentally and economically, and early ban burning fossil fuels contributes to this.

Information of this kind in the media should be restricted in a good way. The spread of detailed description of crimes in the media does produce a negative outcome. In my opinion, I agree that some restrictions should be placed on this kind. However, I also believe that restriction does not mean ban. First, revealing the kind of information in an unsuitable way can cause more crimes happen. The major reason is that criminals are easier to find ways to avoid police and achieve evil plans. The "Red River murders" has set an example. After the police disclosed details when they arrested the killer, a copycat crime happened with a more clever plan as the criminals guess the police position from the news, just a few days later. In contrast, the absolute restriction should not be encouraged in modern society. The public can protect themselves by remembering details such as some deceitful tricks and high-crime areas. A recent study, from the Department of Psychology at the University of Bath, showed that the educational programs and articles can contribute a lot to notice people avoid danger from crimes. Thus, the blackout has never to be a positive way to anti-crime. In conclusion, criminal details should be under censorship. It is therefore wise that some criminal videos are published after viewed by the relevant authorities.

Waste materials need be enough recycled now!!! More often than not, it can observe that waste materials are not utilized effectively in many countries. There are two main reasons: people lack awareness of recycling and companies do not take enough actions. First ,sometime,recycling waste play an invisible but irreplaceable role in environmental protection. It therefore hard for people to realize the importance of recycling in daily life. In addition ,some corporations ,that focus on short-term economic growth, ignore the developing of green industry. A recent study, from the department of sociology at China Agricultural University, shown that 75% people can not recognize the recycling sign and 85% business mans think there are less financial profits in the recycling industry. Since this phenomenon has emerged, it needs governments and individuals to make a joint effort. Governments can enact laws and introduce programs to raise peoples' awareness. Moreover, if the public can pay more attention to recycling products, the companies that manufacture invest more money to design such products.The Chinese government has set a good example in this area. Beijing restaurants are eligible to receive a public subsidy in the range of 50,000 yuan if they buy recycling dinnerware to replace their disposable ones . In summary ,there is no effort is too small when we recycle waste. It will take every one of us to continuously make an effort. Only by doing so can we assure that we will hand the beautiful plants to our next generation, and next generation thereafter.
