英語作文 篇1

cells cannot remain alive outside certain limits of temperature and much narrower limits mark the boundaries of effective functioning. enzyme systems of mammals and birds are most efficient only within a narrow range around 37c;a departure of a few degrees from this value seriously impairs their functioning. even though cells can survive wider fluctuations the integrated actions of bodily systems are impaired. other animals have a wider tolerance for changes of bodily temperature.

for centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. ways of characterizing the difference have become more accurate and meaningful over time, but popular terminology still reflects the old division into "warm-blooded" and "cold-blooded" species; warm-blooded included mammals and birds whereas all other creatures were considered cold-blooded. as more species were studied, it became evident that this classification was inadequate. a fence lizard or a desert iguana-each cold-blooded----usually has a body temperature only a degree or two below that of humans and so is not cold. therefore the net distinction was made between animals that maintain a constant body temperature, called home0therms, and those whose body temperature varies with their environments, called poikilotherms. but this classification also proved inadequate, because among mammals there are many that vary their body temperatures during hibernation. furthermore, many invertebrates that live in the depths of the ocean never eperience change in the depths of the ocean never eperience change in the chill of the deep water, and their body temperatures remain constant.

Who would disagree with the statement “progress is good”? Without progress , there would be no change. Without progress, there would be no change in our economy, our standard of living, or our health.

Progress is required to keep the economy moving forward. New products need to be developed; new services need to be created. Without progress, our economy would stand still. There would be no change. Without progress, there would be no supermarkets with fress produce brought in from all over the world.

Progress is required to improve our standard of living. Our homes today are more efficient and use less natural resources thanks to improvement in home construction techniques. Our clothes are warmer and safer thanks to developments in textile manufacturing. Our educational system is better thanks to the use of the computers and the Internet.

Progress is required to improve the health of the world population. Without progress, there would be no vaccines against deadly diseases like smallpox. Without progress, there would be increased infant mortality. Thanks to progress, our lives are longer and healthier.

Progress is a natural state. Without it, we would not evolve. Without it, our economy, our standard of living, and our health would deteriorate. Who could deny the necessity of progress.

A principals job is not as easy one. I only hope that in the future, I can model my own leadership abilities on the ones I observed in school. I hope I can be as firm, fair, and foresighted as my principal.

今天，年輕一代人過着美好的生活，正由於生活的平靜讓他們感到無聊，因此他們開始追求刺激的運動。跳傘運動對人們來説是很受歡迎，很有挑戰的運動，他們從高山上跳下來，然後打開跳傘，在天空飛翔，看看風景。這是多麼危險啊，但是越危險，人們就越喜歡。跳傘運動是一項如此大的挑戰，因而一些人選擇蹦極，這比較安全，也同樣很刺激。人們從高處跳下來，幾乎抵達水面。重心的失衡讓人們感到死亡的.接近，正是這樣的感覺吸引着人們。但並不是每個人都適合這些冒險運動，那些有心臟病的人是不允許這樣做的。無論人們嘗試哪種運動，安全放在第一位。

英語作文 篇4

Advantages of owning a private car. 2)Disadvantages of owning a private car. 3)Should it be necessary to enlarge the private car market? Why or why not? Nowadays, any Chinese can enjoy the luxury of owning a private car - if he or she can afford it. Having a car of your own means no more traveling to work on crowded buses or subway trains, and you can drop off the children at school on the way. Moreover, it also means that you can enjoy the weekends and holidays better, because with a car you can go to places where theregular buses and trains do not go, and so you can find a quiet scenic spot with no crowds. However, there are drawbacks to owning a car. For one thing, with the increase in car ownership in recent years, the roads are becoming more and more crowded, often making the journey to work more of a nightmare than a dream. For another, it is not cheap to run a car, as the prices of gasoline and repairs are constantly rising, not to mention the prices you have to pay for a licence and insurance coverage. Having considered both sides of the argument, I have come to the conclusion that the advantages of owning a car outweigh the disadvantages. Therefore, it seems to me that China should increase its output of automobiles and enlarge the private car market. The result would be that cars would become cheaper, while at the same time the extra demand would encourage the auto industry to produce more efficient and family-oriented vehicles.

英語作文 篇9

Should Online Education Replace Classroom Education

Nothing has affected our life as swiftly and significantly as the Internet, especially in the field of education. And many of buzzwords such as "Distance Education", " Cyber Classroom" and "Online Study" are more and more frequently heard of. With the increasing popularity of online education, some individuals claim that online education will take the place of traditional way of classroom edcuation soon. However, given more rational consideration and careful observation, it has to be admitted that the possibility of the dominance of online education in all aspects is quite slim.

Firstly, in the process of online education, the degree of interactivity between teachers and students is bound to decline. On the one hand, students will tend to be impassive receivers, as they can not raise questions whenever they want to, and they are not able to share their opinions with other classmates, since they barely meet each other. Moreover, most students may fail to control the minds if the lecture in the computer is abstract and abstruse. On the other hand, teachers can't gain sufficient and elaborate feedback from students. Thus, in most cases, they will be engulfed in a swamp of doubts whether their teaching program and pace are appropriate for each individual student. As is known, teaching and learning are closely related and should be compatible with each other lest the untoward consequences turn up.

Besides, online education given in the cyber space, to a certain extent, is fictitious and intangible, and can't be applied to certain courses. The music class is just the case in this regard. I have been teaching Guzheng---a kind of ancient Chinese musical instrument in a training school. At the initial stage, I have to, face-to-face, teach the students the right gesture of hands, which is the most important step to form a good habit of performance. More often I am obligated to correct their mistakes, especially their hand gestures, and implant a sense of melody to their minds time after time. In this sense, the teachers on the screen might not play the same role as I have, as they are blind to the unique positions and movements of students' hands, or even the potential talent of each student.

Lastly, the substitution of classroom teaching with web-based education will indisputably cause a crisis of unemployment for teachers. It's well acknowledged that technological innovation is a double-blade sword. It brings convenience to more people in their pursuit of education to their own wills while it also demands less quantity of teachers or professors in the case of online teaching. Normally, one teacher can only teach forty or fifty students in a classroom, while now one can teach the whole world as long as he/she has a computer connected to the Internet.

To sum up, cyber education is an unfavorable option with concerns over the apathetic interactivity between teachers and students, as well as the unbearable results of deteriorating unemployment for teachers. In addition, not all the courses can be taught through the Internet. On the contrary , it can be said that classroom teaching is not only pleasant, but also fruitful and efficient. With its eminent advantages, by no means will classroom teaching die out no matter how the world changes.

應該在線教育取代課堂教學

沒有什麼影響了我們的生活作為互聯網迅速而顯著,尤其在教育領域。和許多的術語,如“遠程教育”,“網絡教室”和“在線學習”是越來越頻繁地聽説過的。與日益普及的在線教育,一些人聲稱,在線教育將取代傳統的課堂edcuation很快。然而,考慮到更多的理性思考和細緻的觀察,必須承認這種可能性佔優勢的在線教育在各方面都很苗條。

首先,在這個過程中,在線教育程度、教師與學生之間的互動是肯定要下降。另一方面,學生們將會傾向於防禦接收器,因為他們可以不舉手提問,每當他們想他們不能夠分享他們的意見和其他同學,因為他們幾乎沒有見面了。而且,大多數的學生可能會無法控制思想若演講在計算機是抽象和深邃。另一方面,教師不能獲得足夠的反饋和精心的學生。因此,在大多數情況下,它們會沉浸在一個沼澤的懷疑,他們的教學大綱和速度適合每一個學生個體。眾所周知,教與學是密切相關的,應和睦相處,以免不良後果的出現。

此外,在線教育給在網絡空間,在某種程度上,是虛擬的和無形的,並且不能被應用於特定的課程。音樂類情況是這樣的,在這方面。我已經教古箏―――一種類型的古老的中國樂器在一所培訓學校。在初步階段,我不得不去,面對面,教會學生正確的手勢的雙手,也是最重要的一步養成良好的績效。更多的時候,我是義務去修正他們的錯誤,特別是他們的手勢,並植入一種旋律他們心智一次又一次。從這個意義上説,教師在屏幕上不可能也起着同樣的作用,因為我有,因為他們是瞎眼的,獨特的位置和運動的學生的手,甚至每個學生的潛在的才華。

最後,代替原有的課堂教學和網絡教育的危機會導致失業毋庸置疑的教員。這是很承認,而技術創新是double-blade劍。他會給你帶來方便更多的人們在追求教育他們自己的意願,同時也要求少數量的老師或教授在案件的'網上教學。通常情況下,一位老師只能教四五十學生在課堂,而現在一個人可以教導整個世界,只要他或她有一台連接到因特網上的電腦。

綜上所述,網絡教育是一種不利的選項的關切缺乏感情的互動性教師與學生之間,以及難以忍受的結果為教師惡化失業。另外,不是所有的課程可以教通過互聯網。相反的,可以這樣説,課堂教學不僅僅是令人愉快的,而且卓有成效的和有效的。以其傑出的優勢,絕不課堂教學消亡無論世界如何變化。
