One of the main creators of the World Wide Web，Sir Tim Berners­Lee has warned that the fast growth of the Internet is also creating serious problems.He especially warns of false information being easily spread around the Internet，“A great danger is that it becomes a place where untruths start to spread more than truths，or it becomes a place which becomes increasingly unfair in some way.”In particular he mentions the p henomena of blogging.Blogging enables friends and contacts to easily spread information.However he argues that people may too easily trust information mentioned in a blog.This inaccurate information can then easily become an accepted truth on the Internet.He suggests that the most important development of the Internet will be in creating ways of allowing people to check the correctness of information by providing original sources.Sir Tim admits that this is an important challenge.It's interesting to note that Wikipedia(维基百科)has had to take steps to prevent false information from being added to the biographies of living people.It's easy for anybody to edit the open source.However，some people have pointed out that it has been used to spread false materials.In seeking to raise standards，Wikipedia has sought to stop the false materials.At the same time there is a growing view that the Internet has had a great effect on the way millions of people work.The last two years have seen a big growth in the use of the Internet.There appears no slowdown in the growth of the Internet with increasing access in the developing countries.Sir Tim says another major challenge will be to provide free Internet for everybody.Sir Tim has recently launched a new joint initiative (倡议)between the University of Southampton and the Massachusetts Institute of Technology to create the first degree in Web science.The two schools hope to raise the standards of web content.1．What is the especially serious problem that Sir Tim refers to?A．The growth of the Internet is too fast.B．The Internet has a side effect on young children.C．The Internet companies compete against each other in an unfair way.D．The false information spreads rapidly on the Internet.2．What causes the biographies to have false information?A．The Internet users refuses other users to correct them.B．Wikipedia doesn't take any steps.C．Anybody can easily edit the biographies.D．Wikipedia attempts to publish false materials.3．According to the last paragraph，the purpose of the joint initiative is to ________.A．provide free Internet access to the poor countriesB．improve the reliability of online contentC．create the first degree in science and technologyD．enlarge the use of the Internet4．We can infer from the text that ________.A．Sir Tim has built two schools recentlyB．the Internet is harmful to the people's healthC．Sir Tim hopes everyone can use the Internet for freeD．the Internet develops slowly in the developing countries【解题导语】本文是一篇说明文，主要讲述了互联网的快速发展所带来的一些问题。

Unit 4 Astronomy the science of the stars李仕才一、阅读理解。

Life can be so wonderful, full of adventure and joy. It can also be full of challenges, setbacks(挫折) and heartbreaks. Whatever our circumstances, we generally still have dreams, hopes and desires that little something more we want for ourselves and our loved ones. Yet knowing we can have more can also create a problem, because when we go to change the way we do things, up come the old patterns and pitfalls(陷阱) that stopped us from seeking what we wanted in the first place.This tension between what we feel we can have and what we’re seemingly able to have is the niggling(烦人的)suffering, the anxiety we feel. This is where we usually think it’s easier to just give up. But we’re never meant to let go of part of us that knows we can have more. The intelligence behind that knowing is us — the real us. It’s the part that believes in the life and its possibilities. If you drop that, you begin to feel a little ＂dead＂ inside because you’re dropping ＂you＂.So, if we have this capability but somehow life seems to keep us stuck，how do we break these patterns?Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today’s challenges.While, deep down, we know we can do it, our mind — or the minds of those close to us — usually says we can’t. That isn’t a reason to stop, it’s just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It’s all about starting simple and doing it now.Decide and act before overthinking. When you do this you may feel a little, or large, release from the jail of your mind and you’ll be on your way.1. It can be inferred from the first two paragraphs that we should ________.A. slow down and live a simple lifeB. be careful when we choose to changeC. stick to our dreams under any circumstancesD. be content with what we already have2. What is the key to breaking the old patterns?A. To focus on every detail.B. To decide and take immediate action.C. To listen to those close to us.D. To think twice before we act.3. Which of the following best explains the underlined part in the last paragraph?A. Escape from your punishment.B. Realization of your dreams.C. Freedom from your tension.D. Reduction of your expectations.4. What does the author intend to tell us?A. It’s easier than we think to get what we want.B. It’s important to learn to accept sufferings in life.C. It’s impractical to change our way of thinking.D. It’s harder than we expect to follow a new course.【文章大意】本文是一篇议论文。
