Discuss two sides - modern farming approaches to food production. Due to the population growth in recent years, the challenge of food supply has become a global spotlight. The extensive use of modern farming technology is widely recognized as a positive development to alleviate this problem. However, the promotion of these technologies is not without its criticism and the potential risk, to some extent, plunges the public into panic. This essay will evaluate arguments both for and against these modern approaches. It will examine the modern farming technology in term of the benefit of high yield and potential threat to both human health and the ecological chain. There are a number of arguments in favor of the modern farming technology. As the agricultural mechanization has improved in recent decades, the extensive plantation can be widely implemented. Furthermore, the agriculture production always give priority to the specially selected excellent crop varieties, so that the per unit yield is raised dramatically than before. Therefore, the modern farm technology plays a vital role in the effort to help human beings to get rid of hunger. In this case, the educational background of farmers may become the limiting factor, whereas the increasing overall input level of education will minimize this issue in the near future. There are, however, some valid arguments against the modern farming technology. The genetically modified crops are favored by some specialists because of their advantages, such as insect resistance. Conversely, the customers are suspicious of the security. After all, compared with the traditional food, the genetically modified food has existed only several decades and the experiment data on them may not widely convincing. Besides only a minority of excellent crop varieties are popularized in the modern farming practice. This ignorance on the others may has a detrimental effect on species variety, which may result in the extinction of the relative species feeding on these crops. Thus, the ecological chain would be impacted potentially. In conclusion, every technology has its drawbacks, even though the modern farming technology has its disadvantages and has plenty of room for development. We should recognize its important role in alleviating poverty and the priority is to optimize technologies and take full advantage of them.

How to avoid the ambiguity in this sentence. malapps = malicious application 1. We conduct extensive experiments on large real-world app sets consisting of 100,000 benign apps collected from six app markets and 20,000 malapps. Q: "The set consists 100,000 benign apps and 20,000 malapps.", this is the original meaning. When appending " collected from six app markets", possible ambiguity ensues as following: 1) consisting of [100,000 benign apps collected from six app markets] and [20,000 malapps]. 2) consisting of 100,000 benign apps collected from [six app markets] and [20,000 malapps]. How to improve it and avoid this ambiguity? 2. With the selected discriminatory features, the Logistic Regression classifier yields the best true positive rate as 96% with a false positive rate as 0.06%. Q: I feel there is something wrong in this sentence, but I cannot tell the point. Is it a local, precise expression?3. "K Lab reported that they found 15,000 new unique malicious programs that ran on smartphone in the first half of 2014, which is 20.1 percent more than in the entire year of 2013." Q: Another annoying contrast between numbers. Is it a local, precise expression? Thanks.

Chinese undergraduates, what's wrong with your social communication skill? Before several years, I had a experience living with three Chinese undergraduates. At the first day I moved in my new room I knocked their doors and said hello to them. They seemed introverted and a little bit cold. Considering their age, that was normal to me. After all, it was their first time to live abroad. During the following months, I came to chat with them actively and the situation began to change. I found they were not introverted. Conversely, when we talked about some interesting topics they always present much more actively than before. I thought I rebuild myself to be an approachable person successfully in front of them which resulted from my effort to communication. However, I found an eccentric phenomenon at the same time that they hardly talked with each other. Most of the time, they stayed in their rooms with door closed. I had never seen any of them asked for others something, maybe they would rather ask their classmates for help through Wechat or QQ. People can chat with their friends at any time, so is that the justification for the ignorance on people around?

[note] HR – who even needs it? Link: https://au.finance.yahoo.com/news/hr-%E2%80%93-who-even-needs-it-045341668.html It makes sense that you can’t spell “hurt” without “H” and “R”, and when we see the anti-HR mobs baying for blood, it’s easy to pick up a placard and/or blunt object and join in the fun. -------------------------------------------------------------------------- * See anti-HR mobs baying for sth * pick up a placard or blunt object and join in the fun. There’s a swag of anecdotal “evidence” claiming that HR is no good, despite legitimate research that says otherwise, so let’s get rid of HR! -------------------------------------------------------------------------- * a swag of anecdotal "evidence" * get rid of So, we might say that we should get rid of the HR people, but somebody will still have to fill the HR function. Who’s going to do this? -------------------------------------------------------------------------- * fill the HR function * HR is, after all, the easy job — something anyone can pick up, right? * resolve interpersonal grievances. * HR people need to be competent in HR
