比如：None can negative the importance of money.
改为：None can deny the importance of money.
比如：When one have money, he can do what he want to.
分析：one是第三人称单数，因此本句的have应改为has; want应改为wants, 本句是典型的主谓不一致。
改为：When one has money, he can do what he wants (to do).
比如：I believe I can do it well and I will better know the world outside the campus.
比如：There are many ways to know the society. For example by TV, radio, newspaper and so on.
分析：本句后半部分"For example by TV, radio, newspaper and so on.”不是一个完整的句子，仅为一些不连贯的词语，不能独立成句。
改为：There are many ways to know society, for example, by TV, radio, and newspaper.
比如：At the age of ten, my grandfather died.
分析：句中"at the age of ten"只写出十岁时，但没有说明“谁”十岁时，按一般推理不可能是my grandfather, 如果我们把这个悬垂修饰语改得明确一点，读者或考官在读句子时就不会误解了。
改为：When I was ten, my grandfather died.
“The video camera provides such an accurate and convincing record of contemporary life that it has become a more important form of documentation than written records.”
“The video camera provides such an accurate and convincing record of contemporary life that it has become a more important form of documentation than written records.”There have been many methods of documenting in the history of human， from carved ancient pottery to sheepskin documents， of which the video camera may be the newest form with certain superiorities and inferiorities to written records. The advantages of video camera certainly make it an important form of documentation， but not to the extent of being more essential than written records due to its disadvantages.
To begin with， video can be interpreted as a series of pictures associated along the time， while written records can be considered as the descriptions of these pictures.Therefore， it is undoubtedly that video contains much more information than that of written records. From a video， we can clearly know what happened with subtle details.Merely with a television set， we can easily watch the happenings at home， such as the Olympic Games， comfortably sitting on the sofa， needless to be present on the spot.
And more excitedly， certain close-up enables us to scrutinize our favorable athletes. If there isn‘t video camera， we may be unable to enjoy such activities unless we can afford time and expense to be on the spot. While it is true that we can also be acquainted with the circumstances through newspaper or other media， however， the written record may be unable to present them as accurate as video. The imagination from the reports， however detailed， dooms to be imaginary， by all means different from the real circumstance， which video can represent. Moreover， the written records may contain some mistakes due to the carelessness or injustice of its reporters， while the video may be more accurate and convincing.
Another strongpoint of video is that it can be perceived simply by visual signals， from which people mainly get information in their daily lives， and therefore this method is more natural than written records. Everyone， ranging from a babbling child to an old grandpa， is able to get some information from the video just as they do during their daily lives， regardless of their literate ability. While the written record， no matter how easily it is represented， requires literacy of its readers， and a newspaper or book means nothing to an illiterate person. In addition， video is much easier to comprehend for people all over the world. For instance， an American can grasp nothing about a story written in Chinese unless s/he has learnt such a foreign language. However， s/he can absolutely understand something about a video recorded in China， although s/he may be confused with the language spoken in the video.
While video is certainly not superior to written recorders in all aspects， its limitations determine that the written record will not be replaced at least at present. The first disadvantage of video is that it is much more inconvenient and expensive. Video must be recorded on the spot， namely， when an event happens to you， you cannot record it unless you have a camera at hand. However， even though you haven’t paper and pencil either， you are still able to recall it to record based on your remembrance.
Therefore， for those who can’t afford a handy camera or who are unwilling to bring it anytime anywhere， the written records may be the easiest form available. Further， another weakness of video is that its cost is too high and its correspondingly high-quality record may be beyond people‘s requirement. The cost of making a written report is much less than that of manipulating a video. Also， every morning we may browse a newspaper to know what happened throughout the world， and the simple report， which may only consume us a few seconds， meets our needs of curiosity; we needn’t the accuracy and vividness of video， which may be more time-consuming.
Although innovations such as video，computers，and the Internet seem to offer schools improved methods for instructing students，these technologies all too often distract from real learning.
Nowadays there is a growing concern about the role that innovations have played in the field of learning. While most people think that innovations benefit learning process in various ways，different opinions arise that these technology advancements actually distract students from real learning. On balance，according to my personal observation,whether innovations can be beneficial or detrimental to real learning depends on the students and the teachers，not on these innovations themselves.
To begin with，technological innovations do help teaching and learning in various ways.With the aid of these technologies，the process of teaching and learning can be shorter and easier than before. For instance，if a student want certain published papers of an academic discipline，he/she may look through considerable catalogs to find the ones he/she needs. However，with the help of Internet innovation，at present most of these papers are published online. Consequently，to find certain paper the procedure is much easier and shorter，the students just type the key words and other information of the paper，and then the system will search the database，and the papers are there waiting for them. As this new approach can save a lot of time for the students，he/she could have more time reading the papers and absorbing the knowledge rather than checking and looking for the papers that could be a waste of his/her time. This example aptly illustrates how technology advancement benefited the students and their learning process.
Secondly，while innovations can help learning in various ways，it is more important that the central role of the pursuit for knowledge and wisdoms are maintained. What real matters is not the approach but the purpose of learning. In India，where modern technologies are less applied to the learning process than in the US and other developed countries，still a lot of distinguished students achieved their academic goal with their hard work and desires to knowledge. In the US，where the software engineering students are given the most advanced facilities and apparatus for their learning and research，however，it is wildly accepted that they are far less outstanding compared to the Indian students of software，who may share computers in groups. From this comparison we can see that the real and core push of learning is the desire for knowledge，not the help of innovations.
In addition，if not guided properly，the technology advancement might inhibit learning.In other words，innovation can distract the students from real learning than helping them. It is obvious that a computer can help students of science to calculate mathematical equations but can also be used for recreation such as net surfing or computer games. It is highly possible that these students can spend more time and energy on recreations rather than learning when using a computer. Thus，learning is inhibited. Under this circumstance，guidance and restrictions are needed to ensure the right use of innovations for learning，or the consequence may be on the contrary to the students and teachers' desire.
