一、善用连接词把短句改长句如，一个句子+逗号+however+另一个句子，这里面however是没有实际意义的，就是表转折，但你可以用这招把两个简单句捏在一块啊!短句子成长句了!都希望写下很长的句子，像个老外似的，可就是怕写错，怎么办，最保险的写长句的方法就是这些，可以在任何句子之间加and，但最好是前后的句子又先后关系或者并列关系。
比如说：I enjor music and he is fond of playing guitar.如果是二者并列的，我们可以用一个超级句式：Not only the furcoat is soft，but it is also warm.二. 如何提升作文档次1.简单的改用一些单词也会有意向不到的效果：如用extraordinary代替very:十个人九个用very而你用extraordinary，那你不就与众不同了吗.用significant代替important用as a consequence代替as a result用therefore代替so,举个例子，I got up early，therefore i was late. 写文章还是应该写一些实际的东西，不要空话连篇。
这就要求一定要多用实词，少用虚词。
我这里所说的虚词就是指那些比较大的词。
比如我们说一个很好的时候，不应该之说nice这样空洞的词，应该使用一些诸如generous，humorous，interesting，smart，gentle，warm-hearted，hospital之类的形象词。
简单的替换一下，水平立刻显现出不一样了◆其他连接词：表递进关系，用"furthermore”，"what is more”表转折：however/but但是表对比：n ot that …but that…不是…而是…/one hand….on the other hand一方面…另一方面…/unlike…与…不同/not so much….as…与其…不如…表目的：for the……….为了…表因果：therefore因此，所有/ so 所以表例证：for example表假设：if 如果表让步：although…虽然……(注意：后不可接but!虽然但是不可这样连用)/of course当然…/clearly…显然…◆相关过渡语1)表示时间顺序：first，then，afterwards，meanwhile，later，first of all，finally，at last…2)表示空间顺序：near，next to，far from，in front of，on the lef t，on one side…3)表示比较、对照：like，unlike，such as，but，however，on the other hand，on the contrary，nevertheless，otherwise…4)表示因果关系：because，for，as a result，therefore，thus…3. 巧妙修改句式举个例子，我不光唱歌，而且跳舞怎么说?i not only sing ，but also dance，改动一下，not only do i sing，but also dance.倒装句!I think that...... 宾语从句，老师批10张卷子看到8张里面有I think that不烦吗?如果一定要用宾语从句的话换一种说法：I have a thought that......别看只改动了一点，同位语从句!同样I hear that谁都会用，不过同样谁都会用最好不要用!厉害一些的人会用：It is reported that......牛人会用There is a piece of news that同样的意思，但明显比I hear that要帅!还有一种用并列巨额代替定语从句，不仅可以用来凑字数，还很醋。
举个例子，我喜欢玩篮球，然后篮球有很多种特点，就可以把这些特点用定语从句的形式并列出来：I love basketball，which is......，which is......，which is.......四：最后分享一些可替换使用的单词1.occur 替换think ofSuddenly I had an idea that someone had broken into my hou se. →An idea occurred to me that someone had broken into my hou se.It occurred to me that someone had broken into my house. 2.devote替换spendHe spends all his spare time in reading. →He devotes all his spare time to reading. 3.seek替换want / look forThey sought ( wanted ) to hide themselves behind the trees.4.average 替换ordinaryI’m an average ( ordinary ) student.5.but替换veryThe film we saw last night was very interesting. →The film we saw last night was nothing but interesting.The film we saw last night was anything but boring.6.seat 替换sitOn his way to school，he found an old lady seated (sitting) by the road，looking worried.7.suppose 替换shouldHe is supposed to ( should ) have driven more slowly.8.appreciate 替换thankThank you very much for you help. →We appreciate your help very much. / Your help is much appreciated.9.the case替换trueI don’t think it is the case ( true ).10.on替换as soon asAs soon as he arrived，he began his research. →On his arrival，he began his research..11.due to替换because ofHe arrived late due to ( because of ) the storm.12.cover替换walk/readAfter covering (walking) 10 miles，we all felt tired.13.contribute to替换be helpful/usefulPlenty of memory work is undoubtedly helpful to English stud y. →Plenty of memory work will undoubtedly contribute to English study.14.round the corner 替换coming soon/ nearby①The summer vacation is round the corner ( coming).
