有几种句式比较常用，但是因为中英文习惯上的差别，中国作者比较容易出错。 1. 因为...所以 中文里我们说到原因和结果，用因为… 所以… 的句式，那写成英文是because...so...吗？不是的。英文里because和so不能同时出现在一个句子里，只要用其中一个就可以了。 It will snow this evening, so I'm going home now. Because the mutant receptor has higher affinity for the ligand than the wild-type receptor, it can effectively block the binding of the ligand to the wild-type receptor and the downstream signaling. The mutant receptor has higher affinity for the ligand than the wild-type receptor, thus it can effectively block the binding of the ligand to the wild-type receptor and the downstream signaling. So在科技写作中很少见，一般是用thus. Therefore和hence也可以。 2. 虽然...但是... 和上面的结构一样，英文中虽然(although)和但是(but)也不能出现在同一个句子中，只要用一个就可以了。 GATA6 is known to play important roles in heart development, but its role in the hematopoietic system has not been well studied. Although the mutant mice received the same dose of LPS, all of them survived through the experimental period. 3. 不仅...而且... 这个我们都学过，是not only...but also... He is not only a world-class athlete, but also a world-class chef. He not only wrote the story, but also drew the pictures for the book. 用这个句式一句话说明两个意思，显得简练，但是要求两部分的结构要对称。在科技写作中这个句式实际上用得很少，尤其是两个从句都很长很复杂的时候，很难做到两部分对称，就不适合用这个句式了。我们建议中国作者尽量不要用这样的结构，除非是简短的句子，而且保证两部分对称。如何改写这样的句子呢？拆成两个句子，中间用in addition来连接。 Furthermore和moreover也可以用来代替in addition。这三个词之间存在一些细小差别，不过我们可以忽略。 4. 一方面...另一方面 On the one hand....on the other hand... On the one hand, the story has an interesting plot, but on the other hand, the writing is so poor that I can’t stand reading it. 这个句式我们建议中国作者不要在论文中使用一方面这个句式不够正式，另一方面很容易用错。在英文中这个句式只能用来表达两个相反的意思，是为了突出两者之间的矛盾才用这个句式。但是在中文里并不一定要表达相反的意思，经常我们用这样的句型是为了从两个不同的角度来支持同一个观点。那么怎么改写呢？如果确实是表达相反的意思，就用but在中间连接就可以了。像上面的例句，去掉“On the one hand, on the other hand”而只保留“but ”，意思也不变 。Conversely和However也可以用来连接表示相反含义的两句话。如果表达的是近似的意思，也可以拆成两句，然后中间用in addition, furthermore 或moreover来连接。 （此文由LetPub编辑原创，转载请注明来自LetPub中文官网： www.letpub.com.cn/index.php?page=sci_writing_30 ） 进一步了解， 请点击查看： www.letpub.com.cn SCI论文英语润色 │ 同行资深专家修改 │ 专业翻译 │ 格式排版整理 │ 联系我们 相关资源： SCI影响因子查询 SCI论文写作辅导材料
最近收到主编发来一篇论文的审稿结果，其中一位审稿人提出这么一条建议 The appropriate grammar concerning the writing of numbers that pertain to this draft (and should be addressed) are: 1) spell out single digit whole numbers,but use numerals for numbers greater than nine; 2) be consistent of usage withina category (i.e. if you use numerals for a number greater than nine, thencontinue to use numerals for all numbers in that category, and vice versa); 3)Write out a number if it begins a sentence. 一开始，没有明白什么意思，于是用Google收了一下，发现数字的写法还是很有讲究的。相关规则如下。 Writing Numbers Rule 1 Spell out single-digit whole numbers. Use numerals for numbers greater than nine. Examples: I want five copies. I want 10 copies. Rule 2 Be consistent within a category. For example, if you choose numerals because one of the numbers is greater than nine , use numerals for all numbers in that category. If you choose to spell out numbers because one of the numbers is a single digit, spell out all numbers in that category. If you have numbers in different categories, use numerals for one category and spell out the other. Correct: My 10 cats fought with their 2 cats. My ten cats fought with their two cats. Given the budget constraints, if all 30 history students attend the four plays, then the 7 math students will be able to attend only two plays. ( Students are represented with figures; plays are represented with words.) Incorrect: I asked for five pencils, not 50. Rule 3 Always spell out simple fractions and use hyphens with them. Examples: One-half of the pies have been eaten. A two-thirds majority is required for that bill to pass in Congress. Rule 4 A mixed fraction can be expressed in figures unless it is the first word of a sentence. Examples: We expect a 5 1/2 percent wage increase. Five and one-half percent was the maximum allowable interest. Rule 5 The simplest way to express large numbers is best. Round numbers are usually spelled out. Be careful to be consistent within a sentence. Correct: You can earn from one million to five million dollars. Incorrect: You can earn from one million to $5,000,000. Correct: You can earn from five hundred to five million dollars. You can earn from $5 hundred to $5 million. Incorrect: You can earn from $500 to $5 million. You can earn from $500 to five million dollars. Rule 6 Write decimals in figures. Put a zero in front of a decimal unless the decimal itself begins with a zero. Examples: The plant grew 0.79 of a foot in one year. The plant grew only .07 of a foot this year because of the drought. Rule 7 With numbers of four or more digits, use commas. Count three spaces to the left of the ones column to place the first comma. If the number contains seven or more digits, continue placing commas after every three places. Examples: $1,054.21 2,417,592 Rule 8 The following examples apply when using dates: Examples: The meeting is scheduled for June 30. The meeting is scheduled for the 30th of June. We have had tricks played on us on April 1. The 1st of April puts some people on edge. Rule 9 When expressing decades, you may spell them out and lowercase them. Example: During the eighties and nineties, the U.S. economy grew. Rule 10 If you wish to express decades using incomplete numerals, put an apostrophe before the incomplete numeral but not between the year and the s . Correct: During the '80s and '90s, the U.S. economy grew. Incorrect: During the '80's and '90's, the U.S. economy grew. Rule 11 You may also express decades in complete numerals. Again, don't use an apostrophe between the year and the s . Example: During the 1980s and 1990s, the U.S. economy grew. Rule 12 Normally, spell out the time of day in text even with half and quarter hours. With o'clock , the number is always spelled out. Examples: She gets up at four thirty before the baby wakes up. The baby wakes up at five o'clock in the morning. Rule 13 Use numerals with the time of day when exact times are being emphasized or when using A.M. or P.M. Examples: Monib's flight leaves at 6:22 A.M. Please arrive by 12:30 sharp. She had a 7:00 P.M. deadline. Rule 14 Use noon and midnight rather than 12:00 P.M. and 12:00 A.M. Rule 15 Hyphenate all compound numbers from twenty-one through ninety-nine . Examples: Forty-three persons were injured in the train wreck. Twenty-three of them were hospitalized. Rule 16 Write out a number if it begins a sentence. Examples: Twenty-nine people won an award for helping their communities. That 29 people won an award for helping their communities was fantastic! OR That twenty-nine people won an award for helping their communities was fantastic! （http://www.grammarbook.com/numbers/numbers.asp）
