The lake lay before me, blue and peaceful, in the evening (36) . On either side the mountains rose sharply surrounding it in a kind of bowl. A few sheep (37) their sides here and there and a cow was (38) with eating on the lower slopes. The place was so far away, so untouched by human work that it seemed the very place to (39) . Even Higgs, I thought, won’t be able to find me here.

I sat down by the edge of the lake, and pulled (40) my shoes and socks, put my (41) in the water. It was cold, like ice. After a moment I (42) over and spread some of the (43) on my hot face. I could see myself faintly in the water staring at me like a (44) .

I realized suddenly how (45) I was of running away. Surely, I thought I could live here for a few days, out of (46) of Higgs and his men. While I tried to (47) some plans for the future, I found a tiny cottage on the far side of the (48) with some smoke coming from its roof. I still had a little money. Perhaps they would give me a (49) and some food.

As I watched, a man came out of the house and down to a little (50) at the lakeside. He got into it and began to move (51) towards my side. I could not see his (52) at first. He continued calmly (53) the lake, and when he was about halfway, he rested his oars and the boat drifted into a patch of sunlight. He (54) a hand in a friendly way of greeting.

WASHINGTON -- considering the serious warnings lately about Internet viruses(病毒), users may don’t use their machines just to keep them safe. In reality, common sense and a few basic tips can keep Internet surfers secure.

Anti-virus software is a must, and it should be updated at least once a week to recognize newly viruses. If this is not done, you will meet great troubles.

People with broadband Internet connections should have also a firewall. These protect the computer from attacks by hackers(黑客).

Then it is time to think about computer habits. Unlike old viruses, which spread only through shared disks, the Internet brings viruses straight to the e-mail box. ff an e-mail with attachment(附件) comes from an unknown sender, or unexpectedly from a known’ sender, it should not be opened.

On receiving an unexpected attachment from a friend, experts suggest a telephone call to make sure of the mail’ s source before opening. If you open the mail without any consideration, you will be easily attacked by the hackers.

When I come across a good essay in reading newspaper, I often feel like cutting and keep it. But just as I am about to do so I find the article on the opposite side is as much interesting. It may be a discussion of the way to keep in good health, or advice about how to be oneself in society. If I cut the front essay, the opposite one is bound to suffer damage, leaving out half of it or keeping the text without the subject. As a result, the scissors would stay before they start, or halfway done. when I find out the result that inevitably(不可避免地) causes my regret. Sometimes two things are to be done at the same time, both, deserving your attention. You can only take up one of them, the other has to wait or be given up. But you know the future unpredictable (不可预见的 )--the changed situation may not allow you to do what is left behind. Thus you are caught in a fix and feel sad. How come that nice chances and brilliant ideas should gather.around all at once It may happen that your life changes dramatically on your preference of one alternative to the other.

In fact that is what life is like: we are often faced with the two opposite sides of a thing which are both desirable like newspaper cutting. It often-occurs that our attention is drawn to one thing only after we take up another. The former may be more important than the latter and give rise to a divided mind. I still remember a philosopher’ s(哲学家) remarks: "When one door shuts, another opens in life. " So a passive choice may not be a bad one.

Whatever we do in our lifetime, wherever life’ s storm makes us go, there must be something we can achieve, some shore we can land on. Don’ t forget God always keeps an alternative door open for everyone. While the front door is closed, there must be another open door for you.
