There are various reasons why cancers appear to be on the increase. For one thing, though their sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their middle and advanced years. Naturally, since people live longer these years, there are more cancer sufferers than before. Again, with better methods of diagnosis (诊断), doctors can more easily recog??nize cancerous growths that would formerly have passed unnoticed or that would have been wrongly di??agnosed. It is also believed that certain habits and conditions of modem living, including heavy smok??ing and the pollution of the air, may leave people living in more cancer-causing conditions than before.
We all look forward to the day when a simple medical test can find cancer while it is still small. Researchers around the world are working on such a test. Most of their work deals with the examina??tion of the blood.
Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.
The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.
The test examines very small bits of fat in the blood called lipids (脂质). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.
The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.

The unquestioned role of a student is to learn as much as possible through whatever means it takes to acquire knowledge.Teachers and professors are human beings and are therefore not perfect.No one knows the correct answer to every question even when you limit the questions to a certain field of study.Having certain skepticism(质疑)about what they are being taught can help students to make the teachers even better by correcting mistakes and misinformation.
Students certainly have a huge role in their own abilities to learn.Teachers should act more as guides along the way rather than try to force each student to learn.The best teachers in the world cannot teach an unmotivated student.If the teacher，for whatever reason，cannot motivate the student，then the student must somehow find a way to motivate himself or herself.
One method of doing this is by becoming an active rather than a passive student.The more the student involves himself or herself in the act of studying，the better he or she can learn.One of the best ways to become more active is simply to ask the teacher or professor questions.Students who passively sit in a classroom and take everything that the teacher says for granted are not fully using their mental capacities to learn.
Better education comes from teachers who are able to get their students to think about a subject rather than merely absorb a certain amount of information.Having a healthy skepticism can improve a student's ability to both think and absorb knowledge in a learning situation.
Teachers are human beings and no one is one hundred percent right all the time，even in a classroom situation.Perhaps a teacher would simply unconsciously say the wrong word or pass on some misinformation that the teacher truly believed was correct.A student's question could prevent an entire classroom from becoming confused or misinformed.
There is of course a fine balance between a student having a healthy skepticism，and just being a downright skeptic.But with the proper attitude toward learning and a little skepticism，both the students and teachers can improve upon the learning process and maximize learning efficiency.

One day Tom and I were walking down the street while we saw an old man fall off his bike. He was badly hurt. Many people crowded around us. Someone suggested carrying the old man to the roadside, so Tom disagreed. He has learned first aid. He said that they ought to leave him where he was and checked him first. At that time the old man wasn't breathing. Tom asked me to call in the First Aid Center at once and he began to start the old man's breathing, use the mouth-to-mouth way. Within five minutes, the old man began to move little and doctors also arrived. They said that we had done was correct. I have learned from this experience that a knowledge of first aid can make a really difference.
