The introduction of research essay- Supervised injection sites I did one yesterday, but I decided to change my opinion, so there is a new introduction here. Also, need some academic correction in grammar, words choice. :) -------------------- How can an illegitimate behavior be sanctioned just because it happened under a specific place? The matter of the fact, this is happening in a supervised injection site. Supervised injection sites (SIS) are facilities whose aims is “harm reduction” for those illicit drug users. SIS first emerged in The Netherlands since 1970s, then imitated by Switzerland, Germany and more other countries (Macdonald 2011). Until 2019, there are 100 SIS all over the world, which brings a lot of advantages to drug users and the communities around it. By research into the individual outcome of harm reduction, the impact of the communities around SIS and the economic efficiency, SIS is definitely a beneficial implement for the drug policy.

The introduction of an 1000 words research essay Need some academic correction in grammar, words choice. :) ------------------------------- A supervised injection sites (SIS) is a facility aims for “harm reduction” had emerged since 1970s (Macdonald 2011) in The Netherlands. Until 2019, there are 100 SIS all over the world, mostly established in Europe, and there is only one SIS in North America where located in Vancouver, Canada. Are the world benefited from the emerging of SIS? If yes, why there is only one SIS established in North America during the past fifty years? Considering the origins of SIS, the individual outcome of harm reduction and the impact of the communities around SIS, the expansion of SIS should be suspend and reconsidered after more comprehensive surveys and studies.

Ways in which people could be encouraged to take more exercise. Do you like sport? Do you do exercise like a routine or only do exercise at the time when you want yourself looked fiter? Although we know exercise is an important part for us to keep ourselves healthy, keep us in a good shape and make our thought sharper, there are still many people do not like exercise. What is more, ever you are not that hate sport, it still seems difficult to maintain a consistent sport habit. Is there any way to change it? First, the education is always essential. Not only well broadcast the various beneficial influence a good sport habit can bring, but the relative physiology and mental change during our workout. For example, why some of us feel painful when jogging while others feel they can run forever without limit? If we can know more about where those uncomfortable feeling come from during exercise, and we be well taught about how to deal with it or how to ease the desire to quit, we are more likely to get used to exercise. Second, talking about not to quit a good habit, no other way is better than make sport a compulsory obligation at work and school. We all have this familiar experience that we set up a goal to go to the gym every day after work, we maintain it for a week and then we have to stop it because we work a double-shift a single day the next week. there are thousands excuses for us to quit the painful activity though we are so benefited. Therefor, why not make it an unchoosable task? Weather we like it or not, we need to do it and we will get the advantage either way. Furthermore, sport is that kind of activity that as you start used to it, you would be more and more thirsting for it. That someone make the exercise a rule at the painful beginning will help a lot. In conclusion, there ate ways other people can help to encourage us to do exercise, but it is certainly true that we have to cat ourselves. So, just do it! Let's sport!

Use or learn or know a language I've been learning English for more then 20 years. But not until the recent tow years, I can not say that I speak English. Before you can only say I "KNOW" English. Because, I maybe know the grammar, know a lots vocabulary, but I couldn't ask or answer a completed question even maybe I understood. And most of the time, I did not understand, especially when it comes to the very quickly, unclear pronounced daily conversation. And how come I can say I speak English recently? Cuz, I "USE" English. I went to aboard and lived aboard for tow years. I needed to use English. Even thought I can't speak a completed sentence, I still need to speak! Or else I would die. So, little by little, I started speaking English, and get the feeling of that I can speak English. So, there is the little feedback of my two years aboard life, when learning a language, use it! Or you're just know it.
