迷茫的小羔羊Little lamb lost人生，何谓人生？有的人认为人生是创造，有的人认为人生是追求功名利禄，有的人认为人生是给予。但我认为人生就是生下来，有自己的目标活下去。Life, what is life? Some people think that life is creation, some people think that life is the pursuit of high official positions and riches, some people think that life is given. But I think life is born, have their own goals and live.有的人早已为自己的人生制定了一个完美的人生计划了，并去实施这个计划了。但人生对我来说很迷茫。我也曾为我自己制定了一个人生计划。我的人生计划是这样的：初中毕业之后就去学技工，将来出来工作了，攒些钱，然后自己再开个店。或许在别人看来我这个人生计划很好。但我很纠结，担心自己学不好。我也想过在毕业之后就直接去打工了踏入社会磨练一番，然后有可能去当兵。家里的父母长辈也希望我去学技工。我很反感我的人生被别人主宰，但我却对未来一片迷茫。Some people have for their own life made a perfect life plan, and to implement the plan. But life for me is very confused. I have my own make a life plan. My life is like this: after graduating from junior high school to learn the craft, will come out to work, save some money, and then they open a shop. Perhaps in the eyes of others I this life plan is very good. But I got so nervous, afraid of bad science. I also thought that after graduation directly to work into the community to hone a, then there may be go to be a soldier. Parents want me to study at home mechanic. I hate my life being dominated, but I have a confused about the future.人生总想要一个完美的答案，却总是迟迟不能做出决定，人生本来就没有多少日子，当我们还在犹豫的时候，却不知青春已然在悄悄的离去。当我们在迷茫犹豫中挣扎着醒过来的时候，却发现天已经黑了，属于我们的蓬勃青春的日子已经成为历史的尘埃了。The life always want a perfect answer, but always can't make a decision, there is not much time, when we are still hesitant, but I do not know it has quietly leave.

EarthDay originally celebrated at Spring Equinox around March 20, is an annualday on which events are held worldwide to increase awareness and appreciationof the Earth’s natural environment. Now Earth Day is coordinatedglobally by the Earth Day Network,and is celebrated in more than 175countries every year.In 2009, the United Nations designated April22 International Mother Earth最初，地球日是在每年的春分，也就是三月二十号，这一天世界各地都会进行各种活动，希望能够增强人们的环境意识。现金，在同名组织“地球日组织”的协调下，地球日每年都在超过175个国家进行。 2009年，联合国指定每年的四月二十二号为世界地球日。People are more active doing something which isfriendly to the environment on Earth Day, like saving water, collectingrecyclable waste, reducing the uses of chemical materials which could pollutethe environment, etc..世界地球日这一天，人们会更加主动地去做一些有益于环境的事情，例如，节约用水，回收可再回收利用的废物，减少可能造成环境污染的化学物质的使用等等。Nowadays our world is highly developed with the improvementof technology. The wide use of technology helped us build factories,laboratories, mines, dams and all kinds of facilities which are supposed to dogood to the mankind. And of course they have brought and are still bringing usbenifits. But in the meanwhile they are causing and will be keeping causingserious environmental problems, such as all kinds of pollutions, the damage tothe ozonosphere and so on. And with the growing population of mankind, We areacctually ravaging the living condition of other species, which would cause theimbalance or even collapse of the ecosystem.现今，科技的发展带来了整个世界的高度开发。在科技广泛应用的帮助下，我们建立了各种各样的工厂，实验室，矿场，水坝以及其他所有的能够给人类带来益处的设施。这些设施在带给我们利益的同时，也对环境产生了严重的影响，例如，各种形式的污染，对臭氧层的损伤等等。同时，人类人口的增长，我们也在不停地掠夺其他物种的生存环境。这很有可能造成生态圈的失衡甚至是崩溃。Acctually we can treat everyday as the Earth Dayand be aware of environmental protection all the time. In which way, our motherearth could be protected and she would be able to support us much longer.其实，我们可以把每一天都当做世界地球日，每天都有意识地保护环境。这样，我们才能够保护我们的地球，她也能够更长久地养育我们。

On suprasegmental features Introduction So far we havebeen talking about phonetic features as they apply to single phonetic segments,or phones. Phonetic features can also apply to a string of severalsounds, such as a syllable, or an entire word or utterance. The study ofphonological features which applies to groups larger than the single segment,are known as suprasegmentalfeatures, such as the syllable or the word. The study of these features is knownas prosody. It mainly includessyllable, stress, pitch, tone, and intonation. In this paper, I will talk aboutthe suprasegmental features ingreat detail. Key words: phonetic, suprasegmental. Syllable The most obvious prosodic feature in languageis the syllable. Let's briefly discuss the notion of syllables. Like all of our other basic linguistic concepts,although everyone knows what a syllable is, the concept "syllable" isdifficult to define in absolute terms. A syllable can be divided into threeparts, that is, onset, nucleus, and coda, of which nucleus is a must. Asyllable that has no coda is called an open syllable while a syllable with codais called a closed syllable. In English only long vowels and diphthongs canoccur in open syllables. The onset may be empty or filled by a cluster of asmany as three consonants, while the coda position may be filled as many as fourconsonants. The maximal onset principle states that when there is a choice asto where to place a consonant, it is put into the onset rather than the coda.In some languages, syllables are always open,that is, they always end in a vowel, never a consonant. (Hawaiian) On the other hand, every Hawaiian syllable must begin with a consonant. (Aloha spoken as a single word beginsin a glottal stop.) In other languages, syllables are always closed; they mustend in a consonant (Navaho): Háá'ishah dididiljah. Let's build a fire. Táá diné 'ooljéé'go naaskai' Three men went to the moon. (LikeHawaiian, they must also begin in a consonant.)Stress The nature of stress The word stress is used differently bydifferent authors, and the relationship between stress, emphasis, accent andprominence is also defined differently. Robins has defined it as “a genericterm for the relatively greater force exerted in the articulation of part ofutterance”. The nature of stress is simple enough—practically everyone wouldagree that the first syllable of words like“father”, “open” is stressed, thatthe middle syllable is stressed in “potato”, “apartment” and the final syllableis stressed in “about”, “perhaps”, and most people feel they have some sort ofidea of what the difference is between stressed and unstressed syllables,though they might explain it in many different ways.The production of stress is generallybelieved to depend on the speaker using more muscular energy than is used forunstressed syllables. From the perceptual point of view, all stressed syllableshave one characteristic in common, and that is “prominence”. Roach hasmanifested that at least four different factors are important to make asyllable prominent:i) Loudness: Most people seem to feelthat stressed syllables are louder than unstressed ones; in other words,loudness is a component of prominence.ii) Length: The length of syllables hasan important part to play in prominence; the syllables which are made longerthan the others will be heard as stressed.iii) Pitch: Pitch in speech is closelyrelated to the frequency of vibration of the vocal folds and to the musicalnotion of low-pitched and high-pitched notes; if one syllable is said with apitch that is noticeably different from that of the others, this will have astrong tendency to produce the effect of prominence.iv) Quality: a syllable will tend to be prominentif it contains a vowel that is different in quality from neighboring vowels. Languages differ in how they use stress.1) In some languages, eachsyllable is equally stressed or unstressed，as in Cambodian2) the syllable in eachword is more stressed. Theplace of stress is fixed on acertain syllable:1) initial. Finnish,Hungarian and other Finno-Ugric languages2) penultimate. Polish,3) final. French.4) Complex set ofrules. In Bulgarian nouns and verbs have separate sets of rules forstress placement. Hopi (phonetic: first syllable of a two syllableword: síkwi meat; inwords of three or more syllables, accent falls on the first long vowel: máamatsi to recognize; or onthe first short vowel before a consonant cluster: péntani to write; otherwise it falls on thenext to last syllable: wunúvtu standup)The place of stress is random.1) In Russian the stress iscompletely random: xoroshó, xoróshi.2) In English the stress ismore predictable but still random. Usually a middle syllable of a longerword receives the stress. In two syllable words stress is rando and oftenrenders differences in meaning: project/toproject, produce/produce, and insult/ to insult. Some languages have more than one stress perword: English is such a language. In English, words of foursyllables or more have a primaryand a secondary stress. SomeEnglish compounds have phrasal stress on the first element of thecompound. Phrasal stress often distinguishes meaning in adjective/nouncombinations. Sentence stress in English According to He Shanfen (1992), Englishsentence stress has two main functions:⑴ to indicate the important words in thesentence; ⑵ to serve as thebasis for the rhythmic structure of the sentence. Consequently, in connected English speech,sentence stress usually falls on content ( or lexical) words, which carry thebasic meaning of a sentence, e.g. nouns, adjectives, adverbs etc. Those whichare usually unstressed in sentences are form (or structural) words, which showgrammatical relationships, such as articles, auxiliary and modal verbs,monosyllabic prepositions, etc.Pitch Another prosodic feature is pitch, defined as the frequency ofvibration of vocal cords. Pitch is measured in hertzes. Physiologically, pitch tends to be higher inwoman than in men and higher before puberty than after puberty. Also, thepitch of women's voices tends to lower with old age; the pitch of men's voicestends to get higher with age. Despite these physiological, non-linguisticuniversal, each language uses pitch distinctions for linguisticallymeaningful purposes. Startingfrom the lowest pitch on the initial syllable, the pitch of each subsequentsyllable raises until the word reaches the "peak". From that point,pitch either remains at the same level for the remainder of the word or itdrops again. The choice between maintenance of high pitch or allowing it todrop is a matter of formality: pitch is maintained in formal or careful speech,but dropped in colloquial usage.七．ConclusionBeing the most important part, suprasegmental features can not be despised in phonology research.From the whole passage, we can understand that suprasegmentalfeatures not only has its phonology significance, but also the practicaluse as well. We can not say this person is a good language user just by his orher vocabulary, as well as the grammar. Spoken language is also very useful. Ido hope that the paper will be sufficient to prove that suprasegmental features is an efficient way for our studies and encouragemore and more students to pay attention to using it.Reference【1】CaoJianfen.
