题目内容
Computer technology has become a major part of people’s lives. This technology has its own special words. One example is the word mouse. A computer mouse is not a small animal that lives in buildings and open fields. It is a small device that you move around on a flat surface in front of a computer. The mouse moves the pointer on the computer screen.
Computer expert Douglas Engelbart developed the idea for the mouse in the early 1960s. The first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because it had a tail at one end. The tail was the wire that connected it to the computer.
Using a computer takes some training. People who are experts are sometimes called hakers. A hacker is usually a person who writes software programs in a special computer language. But the word hacker is also used to describe a person who tries to steal information from computer systems.
Another well-known computer word is Google. It is the name of a popular “search engine” for the Internet. People use the search engine to find information about almost any subject on the Internet. The people who started the company named it Google because in maths, google is an extremely large number. It is the number one followed by 100 zeros.
When you “Google” a subject, you can get a large amount of information about it . Some people like to google their friends or themselves to see how many times their names appears on the Internet.
If you Google someone, you might find that person’s name on a blog. A blog is the shortened name for a Web log. A blog is a personal Web page. It may contain stories, comments, pictures and links to other Web sites. Some people add information to their blogs every day. People who have blogs are called bloggers.
Blogs are not the same as spam. Spam is unwanted sales messages sent to your electronic mailbox. The name is based on a funny joke many years ago on a British television show, “ Monty Python’s Flying Circus”. Some friends are at an eating place that only serves a processed meat product from the United States called SPAM. Every time the friends try to speak, another group of people starts singing the word SPAM very loudly. This interferes with the friends’ discussion---just as unwanted sales messages interfere with communication over the Internet.

考点:科技类短文阅读
Until just a few years ago,we doctors believed that the brain stopped making new neural(神经系统的)connections (meaning that your memory began to get worse)when the body stopped developing,usually in your early 20s. And we knew that,like any other body part,neurons weaken as we age. Loss of brain function due to neural breakdown was assumed to be a normal,unavoidable part of aging.
It turns out that we were wrong. In the past few years,it has been discovered that you can,in fact,make new neurons starting in your 20s and continuing well into old age. You can literally rewire the brain with new parts as the older parts wear out. How?Simple:Keep learning. Just as your body can pack on and condition new muscle,your brain can rebuild used-up neurons.
How strong is the evidence for this?Strong enough that a $200 million industry devoted to brain boosting software (products like Brain Age,MindFit,and Lumosity that supposedly improve your memory function)has sprung up out of nowhere. All“mental fitness”means are keeping your memory intact(everything from phone numbers to how to throw a football).So what can you do to stay smart?
Keep blood pressure down. People with high blood pressure are more likely to develop cognitive impairment later in life.
Eat more vitamins. Like E(in nuts and sunflower seeds),B6 and B12(beef,tuna),and folic acid(leafy greens,citrus,berries),which help keep your brain’s chemistry in balance.
Exercise your brain. This is the best way to rebuild and strengthen those precious neurons. Learn to play chess or the guitar. When you’re at a stoplight,try to recall the starting lineup of the 1983 Celtics. See a movie that doesn’t feature Ben Stiller. Or read,like,a book.
