英语so that表示结果和目的的用法区别有哪些 "so that"在英语中是一个非常常用的连词，它可以用来引导目的状语从句和结果状语从句，但在这两种用法中，它传达的含义和语气有所不同。 1. 表示目的：当"so that"用于引导目的状语从句时，它表达的是一种意图或可能性。通常，这种从句会出现在主句之后，用以说明前面行动或决定的目的或意图。例如，"I study hard so that I can get good grades."（我努力学习，以便获得好成绩）。在这个例子中，"so that"后面的从句描述了通过学习所能达到的目标或期望的结果。 2. 表示结果：相比之下，当"so that"用于引导结果状语从句时，它表达的是一种事实或结果。这种从句通常会在主句之后出现，并且前面会有逗号或者说话时的停顿，用以强调前面行动或决定所产生的结果。例如，"He studied hard, so that he got good grades."（他努力学习，所以他得到了好成绩）。在这个例子中，"so that"后面的从句描述了努力学习所带来的实际结果。 引导目的状语从句时，表示“以便，为了”，从句中常使用can /could /may /might /will /would /should等词;引导结果状语从句时，从句中一般不用can和may等词，在so that前可以用逗号，意思是“因此，所以”。例如: The little boy saved every coin so that he could buy his mother a present on Mother's day. 为了能够在母亲节给她的母亲买一份礼物，小男孩存下了每一分钱。(目的状语从句) The girl was very hungry so that she ate the wholepizza.那个女孩非常饿以至于她吃了一整个比萨饼。(结果状语从句) 新概念英语mp3 高中英语单词听力 新概念英语mp3下载 人教版初中英语mp3 总的来说，"so that"在表示目的时，强调的是行动的目的或意图；而在表示结果时，则强调的是行动所产生的实际结果或事实。在具体使用时，需要根据语境和句子的含义来选择合适的用法。 In 2016, Japanese scientists found a kind of bacteria, which they called Ideonella sakainesis, could “eat” plastic. The secret for Ideonella sakainesis is enzymes (酶) used by bacteria and other cells to make chemical changes happen. It uses two enzymes to turn plastic into something it can eat. What's left over afterward could be used to make new plastic. One of them, called “PETase”, is the one that breaks down the plastic. Recently, scientists have figured out a way to make the bacteria eat plastic even faster. They did some chemical work with the enzyme PETase. They thought what they did would make it eat plastic even slower. However, they were surprised to find that the change made it eat 20% faster. This is an important step, but it will still be a while before we will know if Ideonella sakainesis can really make a difference. Everything has to be just right for it to do its work. It can't be too hot or too cold. The scientists say they'll keep exploring to make it work in all kinds of conditions. Besides, it only eats one kind of plastic called PET, which is usually used for making bottles. But scientists think it is possible that there may be other kinds of bacteria that eat other kinds of plastic. They think that even if these bacteria don't already exist, they may come along soon. Bacteria can change their habits quickly, compared to bigger life forms. Most plastic can already be recycled, and this is really just a new way to recycle it. However, as scientists warn seriously, Ideonella sakainesis' new function does not change the fact that only about 9% of plastics actually get recycled, while the rest get thrown away. They also point out that harmful chemicals are added when plastic is made. If bacteria break down plastic in natural areas, those poisons will be given off, and could affect plants, animals, or humans. 12. How did the scientists find the fact that the bacteria eat plastic faster? A. They made changes to PETase. B. They added more PETase to plastic. C. They mixed plastic's two enzymes. D. They removed enzymes from plastic. 13. What do we know about Ideonella sakainesis from paragraph 3? A. It breaks down some special kinds of plastic. B. It eats plastic under demanding conditions. C. It stops other bacteria possessing PETase. D. It produces enzymes when eating plastic. 14. What do the scientists convey about plastic recycling in the last paragraph? A. They are confident to do it. B. It's hard to recycle plastic. C. Its situation worries them. D. It has been well done so far. 15. What's the author's purpose in writing the text? A. To advocate recycling plastic. B. To praise scientists' hard work. C. To show severe plastic pollution. D. To introduce a new discovery.
