The important thing isn’t what you might have done differently in the past, if you had been someone that you couldn’t have been back then. It’s what you’d do now. For many people, I know, this can be a huge challenge. But unlike changing the past, it has the great advantage of not being impossible.

Will Experimentation on Animals End?
One of the most debatable issues in science is the use of animals in research. Scientists experiment on animals for different reasons, including basic research to explore how organisms function, investigating potential treatments for human disease, and safety and quality control testing of drugs, devices and other products.
In 1959, William Russell and Rex Burch proposed their “3Rs” guidelines for making the use of animals in scientific research more humane: restrict the use of animals; refine experiments to minimize distress; and replace tests with alternative techniques.
For example, researchers previously had to do experiments with multiple mice at different stages of cancer development, but now they can watch the disease develop in a single living animal using a dye. Similarly, as brain-imaging techniques become more advanced, some questions that were addressed with experiments in monkeys before may be better answered by looking into the human brain now. “
| A．Over the course of five decades their guidelines have become widely accepted worldwide. |
| B．The awareness of animal protection contributes to the decline of the number. |
| C．Human volunteers must be able to replace monkeys more and more in the next 10 to 20 years. |
| D．New experimental techniques help to push numbers down. |
| E．Its supporters point to the long list of medical advances made possible with the help of animal research. |
| F．The number of the animals used in research is still considerable. |
4 . Beginning college is exciting: new ideas to explore, new challenges to meet and many decisions to make．Your future begins here．
However，you will find college life is different from your previous school environment．Many of us can be easily overwhelmed（压垮）by the details of running a well-balanced life．While some of us may have the know-how, I guess there are more of us who can benefit from learning about the experiences of others who have walked the college halls before you．
The following you may find of use about life on campus．
* Plan well．There are so many new things to do at a new college or university．Give yourself time to make new friends and become familiar with the campus, but don’t forget why you are there．Give some time for social activities and manage your time wisely．
* If you don’t have a “system” for planning your time now （like a day timer, a computer data book）, get one．Most of all, don’t depend on your memory．
* Don’t miss the guidelines．The restrictions, rules and regulations of all kinds can usually be found in your student handbook．Consider them well-balanced food for thought．What dates are important? What pieces of paper need to be handed in? What can/ can’t you do in class? What can/ can’t you do in your student residence（住处）? Who has right for what? What do you need to complete to graduate?
* Write the word “STUDY” on the walls of our bedroom and bathroom, and maybe it will help to write it on a piece of paper and stick it on the telephone, TV and the kitchen table．Consider this—you are paying thousands of dollars for your courses．You pay every time you have to repeat or replace a course．
* Build your identity．This is the time for you to decide what to do and what not to do．Take as much time as you need to explore new ideas．Do not be afraid of the beyond．This is learning to make good choices．
