音标是学习英语的重要工具,是学好英语的坚实基础.熟练掌握音标及其拼读规律不仅可以保证单词能够读准,更重要的是可以使学生增强自信心,激发其学习英语的兴趣.因此,语音教学对学生依然重要.近年来,音标的教学不可忽视.
1.什么是英语音标?
什么是音标?音标就是记录音素的符号,是音素的标写符号。它的制定原则是:一个音素只用一个音标表示,一个音标只表示一个音素。如汉语拼音字母、英语的韦氏音标和国际音标等。 狭义上的”音标“意思就是指英语音标。
2.什么是国际音标?
国际音标International Phonetic Alphabet,原义是“国际语音字母”简称IPA,由国际语音协会制定。
1888年,由英国的H~斯维斯特倡议,由法国的P~帕西和英国的D~琼斯等人完成,发表在《语音教师》上(“国际语音协会”前身“语音教师协会”的会刊),这是历史上第一个国际音标表。后经多次修订,现通行的是1979年修订的方案。
国际音标是英法两国学者创定的,主要适用于表注印欧语言、非洲语言和一些少数民族语言。它发表后,在欧洲语言学界比较流行。美国人多数仍用他们自己研究美洲印地安语的符号。
3.什么是kk音标和dj音标?
我们常见有KK音标 和 DJ 音标,那么DJ 音标指的是什么音标呢?
DJ音标跟英国语音学家Daniel Jones有关。他根据IPA编了一本英国英语的发音辞典English Pronouncing Dictionary(第1版至第12版,最后一版的出版时间为1963)。
(附:KK音标是国际音标的一种,DJ音标也是其中的一种。KK音标跟两位美国语言学者J. S. Kenyan和T. A. Knott有关。他们根据IPA所编的描述美国英语的发音辞典(A Pronouncing Dictionary of American English 1944,1953)里所用的发音符号,就是一般通称的KK音标。)
说明:有人误认为国际音标就是注英国音的音标,而KK是标美国音的。这种说法把国际音标说成好像只能用来标英国音,而且把KK音标认为不是国际音标。其实这是不正确的。国际音标,如其名,是设计来标注国际各种语言的发音的,很多语言学家把国际音标做局部修改以标记他们所研究的语言,所以国际音标也有很多种。
KK音标是国际音标的一种,DJ音标也是其中的一种。可是到了现在,这二种标准都已经过时落伍了。英国另一位语音学家A.C. Gimson(他是Daniel Jones的学生,英国伦敦大学的语音学教授),将英国英语的辞典发音做了一番修正(第13版,1977;第14版,1988),使它更能代表实际发音。
4.什么是严式标音和宽式标音?
严式标音和宽式标音的区别:
用音标标记语音的方法叫标音法。一般分为严式标音法和宽式标音法两种。 要记录一种语音,最初的方法应当是严式标音。
所谓严式标音,就是出现什么音素就记录什么音素,有什么伴随现象就记录什么伴随现象。无论什么音素和什么伴随现象都不放过,也就是最忠实、最细致的记录语音的原貌。所以,严式标音又称为“音素标音”。例如,现代汉语中,较低的舌面元音可归纳为一个音位/a/,若用严式标音,则必须分别标为[ε]、[A]、[a]、[ɑ]、[œ]、[æ]等。它的特点就是,对一种语言或方言中实际存在的每一个音素(不论它们是否属于同一个音位),都用特定的音标加以标记。因此,严式标音使用的音标很多,对语音的刻画描写很细致,大多是在调查第一手材料时使用,在其它场合只是间或使用。
所谓宽式标音,是在严式标音的基础上,整理处一种语音的音位系统,然后按音位来标记语音,也就是只记音位,不记音位变体及其它非本质的伴随现象。因此,宽式标音又称为“音位标音”。例如,现代汉语中,舌面低元音有[ε]、[A]、[a]、[ɑ ]等多个,用宽式标音只用/a/就可以了。用宽式标音,可以把音标数目限制在有限范围之内,因而能把一种语言或方言的音系反映得简明清晰。

【答案解析】
1. D. 考查“祈使句/名词+and+陈述句”句型。句意为:“再努力点,你就会成功的”。
2. B. so(因此)是并列连词,引出一个表示结果的分句,前面应是一个表示原因的分句,而无需再用连词,排除A;C和D又不是句子,也错了。
3. D. 因为rather than是对称连词,意为“而不”
4. A. 因为but是并列连词,后面是个句子,前面也一定是个句子,而不是一个分词短语或不定式短语,更不能再用连词though,所以排除B、C和D。
5. C. 考查“祈使句+and+陈述句”句型,意为“如果…就…”。虽然or也可用于此句型,但or是“否则、要不然”之意,如:Work hard, or you’ll fail. (努力学习,否则就会不及格。)
6. D. 因为not only…but (also)…是固定搭配7. D. 因为句中的并列连词for表示原因,是对前面分句所述内容的解释或补充说明。
8. A. 因为句中的并列连词while表示“对比或相反”。
9. B. 因为句中的并列连词when = just at that time, 意为“这时(突然)”。
10. D. 因为只有or才能表示选择,意为“(是…) 还是”。
11. C。本题考查what引导主语从句,并在主语从句中作主语。句意为“在许多国家,所谓的“公立学校”并非公众拥有。
12. B。本题考查引导主语从句的连接词。that引导主语从句只起连接作用,在从句中不作任何成分,无意义,但不能省略。what除引导主语从句外, 还在从句中作成分。which指一定范围内的“哪一个”;whether意为“是否”。根据句意“世上的事喜忧交替”可知答案为B13. D。该题考查宾语从句。可以看作是does it matter which book it was的省略。一定注意此题受母语干扰,很容易错选答案为A。只要抓住题干前一句I read about this story in some book or other的提示,就可知道是指一定范围内的“哪一个”,故答案为D。
14. D。that引导同位语从句;what the book said是同位语从句中的主语。
15. A。本题考查以after引导的时间状语从句,意为“在…之后”。句意为“步行了六小时后,我累坏了”。
16. C。even if=even though,引导的让步状语从句,意为“即使, 尽管”,符合题意。
17. D。本题考查before引导的时间状语从句,意为“在……之前”。句意为“他来不及冲进去救他的孩子,屋顶就塌了”。
18. C。When it comes to. . . 是一固定句型,意为“当谈到……时,涉及”。句意为“做作业是提高考分的一个可靠方法,这在涉及到课堂测验时尤其正确”19. B。该题考查where引导的地点状语从句,表示“在…地方”。句意为“我一直把照片放在我每天都能看到的地方,因为它总使我回想起大学里的日子”。
20. B。so long as=so long as, 意为“只要”,表示条件。句意为“只要你答应归还,你就可以把这书借走”。

在备考英语四级的过程中,各位考生不仅要注意词汇的积累,句型的掌握,还要注意标点符号的正确使用。下面是读文网小编整理的英语四级作文必备知识训练:标点符号的用法,以供大家学习参考。
分号有时又称为小句号。它表示一个停顿,其停顿时间在逗号与冒号的停顿时间之间。文章如采用许多分号,其风格则变得严肃、正式。为了正确使用分号,有必要先学会辨认主句。当两个主句没有任何连接词(and, but, or, nor, for)连接而出现在同一个句子里,这时最好采用分号使之分离。分号的主要作用很简单,它常用于分离没有连接词连接的句子。但最好不要在从句之间形成如此之强的停顿。如果你要连接从句,而又不愿意用连接词时,则采用分号。
The world is a comedy to those that think; a tragedy to those that feel.
You don’t write because you want to say something; you write because you’ve got something to say.
In the past, boy babies were often dressed in blue; girls, in pink.
Can’t you see it’s no good to go on alone; we’ll starve to death if we keep traveling this way much longer.
John F. Kennedy said at his inaugural speech, "Ask not what your country can do for you; ask what you can do for your country."
Our power to apprehend truth is limited; to seek it, limitless.
Science needs to be lived alongside religion, philosophy, history and esthetic experience; alone it can lead to great harm.
下列各词和短语如用于连接复合句时,常与分号连用:
then however thus furthermore
hence indeed consequently also
that is nevertheless anyhow in addition
in fact on the other hand likewise moreover
still meanwhile instead besides
otherwise in other words henceforth for example
therefore at the same time even now
例:
Being clever and cynical, he succeeded in becoming president of the company; meanwhile his wife left him.
The weather was cold for that time of the year; nevertheless, we set out to hike to the top of that mountain.
According to one national survey, high school boys expected a starting salary of $19,500 for their first full-time job; on the other hand, high school girls expected a starting salary of only $15,000.

一、条件状语从句
1、与现在事实相反
若与现在事实相反,虚拟语气的条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”。如:
If I were you, I would take an umbrella. 如果我是你,我会带把伞。(事实上我不可能是你)
If I knew her number I could ring her up. 要是我知道她的电话号码,我就可以给她打电话了。(事实上我不知道)
2、与过去事实相反
若与过去事实相反,从句:主语+had done , 主句:主语+should/would/could/might+have done,例如:
If I'd left sooner,I'd have been on time. 要是我早点动身,我就准时到了。(但我动身太迟了)
If I had got there earlier, I should/could have met her. 如果我早到那儿,我就会见到她。 (事实:去晚了)
3、与将来事实相反
从句:①if+主语+were to do 主句:①主语+should/would/could/might+do
②if+主语+did/were ②主语+should/would/could/might+do
③if+主语+should+do ③主语+should/would/could/might+do
例如:If he went,would you go too? 如果他去,你也去吗?(大概他不会去)
If he should come here tomorrow, I would talk to him. 如果他明天来这儿的话,我就跟他谈谈。 (事实:来的可能性很小)
注意与说明:对于与将来事实相反的情形,请注意以下几点:
一是这里说的与将来事实相反,实为对将来情况的推测;
二是此用法中的条件从句谓语除用过去式外,有时也用“should+动词原形”(表示可能性极小,常译为“万一”)或“were to+动词原形”(表示与将来事实相反的假设);
三是当条件从句使用“should+动词原形”这样的谓语时,主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气外,也可用陈述语气或祈使语气。如:
I should see him, I'll tell him. 万一我见到他,我就告诉他。
If it should rain tomorrow, don’t expect me. 万一明天下雨,就别等我了。
二、wish 后宾语从句
1、表示与现在事实相反的愿望,谓语动词用过去式 。例如:
I wish I had your brains. 我希望我有你那样的头脑。(事实:我根本比不上你)
2、表示与过去事实相反的愿望,谓语动词:had+done 例如:
I wish I had knownthe truth of the matter. 我希望我那时就知道这件事情的真相。(事实:那时还不知道)
3、表示将来难以实现的愿望,谓语动词:should/would(情态动词) + 动词原形
I wish I should havea chance again. 我希望我还能有一次这样的机会。(事实:很难再有这样的机会了)

为了帮助大家强化英语知识点的记忆,下面读文网小编为大家带来初中英语从句相关知识点讲解,供大家参考学习。
原因状语从句应注意的问题
1、because , since , as , for,辨析
1)because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或 since。
I didn’t go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2)由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就只能用for。例:
He is absent today, becaus e / for he is ill. He must be ill, for he is absent today.
3) as和for的区别:通常情况下,as引导的从句在主句前,for引导的从句在主句后。例: As the weather is cold, I stay at home.(同义句) I stay at home, for the weather is cold.
2、because习惯上不与so连用
汉语习惯上说“因为…所以…”,但英语习惯上却不能将 so与because 连用:
正:Because it was raining, we stayed at home. / It was raining, so we stayed at home.
误:Because it was raining, so we stayed at home. 因为下雨,所以我们呆在家里。
3、because 从句与 because of短语的转换
Because引导的原因状语从句有时可与because of 短语转换,because of后加的原因可以为好或坏 ,但最正规的还是because。
He can’t come because he is ill. / He can’t come because of his illness. 他因病不能来。
I said nothing about it because his wife was there. / I said nothing about it because of his wife’s being there. 因为他妻子在那儿,我对此事只字未提。
