What is the explanation of why we have not been visited?
One possibility is that the argument about the appearance of life on Earth is wrong. Maybe the probability of life spontaneously appearing is so low that Earth is the only planet in the galaxy, or in the observable universe, in which it happened.
Another possibility is that there was a reasonable probability of forming self-reproducing system, like cells, but most of these forms of life did not! evolve intelligence.
A third possibility is that there is a reasonable probability for life to form, and to evolve to intelligent beings, in the external transmission phase. But at that point, the system becomes unstable, and the intelligent life destroys itself. This would be a very pessimistic conclusion. I very much hope it isn' t true.
I prefer a fourth possibility: there are other forums of intelligent life out there, but we have been overlooked. There used to be a project called SETI, the search for extraterrestrial intelligence. It involved scanning the radio frequencies, to see if we could pick up signals from alien civilizations. I thought this project was worth supporting, though it was cancelled due to a lack of funds. But we should have been wary of answering back, until we have developed a bit further. Meeting a more advanced civilization, at our present stage, might be a bit like the original inhabitants of America meeting Columbus. I don' t think they were better off for it.
The author thinks that______.
A.it is impossible that we encounter some alien form. of life
B.life only exists on Earth
C.it is likely that we' ll encounter some alien form. of life
D.beings from outer space will never visit the earth

An international travel insurance policy is usually purchased in your home country before you go abroad. It generally covers a wide variety of medical services and you are often given a list of doctors in the area where you will travel who may even speak your native language. The drawback might be that you may not get your money back immediately. In other words, you may have to pay all you medical expenses and then later submit your receipts to the insurance company.
On the other hand, getting student heath insurance in the country where you will study might allow you to only pay a certain percentage of the medical cost at the time of the service and thus you don't have to have sufficient cash to pay the entire bill at once. Whatever you decide, obtaining some form. of health insurance is something you should consider before you go overseas. You shouldn't wait until you are sick with major medical hills to pay off.
(30)
A.It'll enable them to enjoy the best medical care.
B.It'll allow them to receive free medical treatment.
C.It'll protect them from possible financial crises.
D.It'll prevent the doctors from overcharging them.

Two roads led out of the town; one branched off towards the Ambroses' villa, the other struck into the country, eventually reaching a village on the plain, but many footpaths led off from it, across great dry fields, to scattered farm-houses. Hewer stepped off the road on top one of these, in order to avoid the hardness and heat of the main road, the dust of which was always being raised in small clouds by carts and ramshackle flies which carried parties of festive peasants, or turkeys swelling unevenly like a bundle of air balls beneath a net.
The exercise indeed served to clear away the superficial irritations of the morning, but he remained miserable. It seemed proved beyond a doubt that Rachel was indifferent to him, for she had scarcely looked at him, and she had talked to Mr. Flushing with just the same interest with which she talked to him. Finally, Hirst's odious words flicked his mind like a whip, and he remembered that he had left her talking to Hirst. She was at this moment talking to him, and it might be true, as he said, that she was in love with him. He went over all the evidence for this supposition her sudden interest in Hirst's writing, her way of quoting his opinions respectfully; her very nickname for him, "the great Man," might have some serious meaning in it. Supposing that there were an understanding between them, what would it mean to him?
Ever since he had first seen her he had been interested and attracted, more and more interested and attracted, until he was scarcely able to think of anything except Rachel. But just as he was sliding into one of the long feasts of meditation about them both, he checked himself by asking whether he wanted to marry her? That was the real problem, for these miseries and agonies could not be endured, and it was necessary that he should make up his mind. He instantly decided that he did not want to marry any one. Partly bemuse he was irritated by Rachel. The idea of marriage irritated him.
It immediately suggested the picture of two people sitting alone over the fire. the man was reading, the woman sewing. There was a second picture. He saw a man jump up, say good-night, leave the company and hasten away with the quiet secret look of one who is stealing to certain happiness. Both these pictures were very unpleasant, and even more so was a third picture, of husband and wife and friend; and the married people glancing at each other as though they were content to let something pass unquestioned, being themselves possessed of the deeper truth. Other picture--he was walking very fast in his irritation, and they came before him without any conscious effort, like pictures on a sheet succeeded these. Here were the worn husband and wife sitting with their children round them, very patient, tolerant, and wise. But that too, was an unpleasant picture. When, on the other hand, he began to think of unmarried people, he saw them active in an unlimited world; above all, standing on the same ground as the rest, without shelter or advantage. All the most individual and humane of his friends were bachelors and spinsters; indeed he was surprised to find that the women he most admired and knew best were unmarried women. Marriage seemed to be worse for them than it was for men.
The word "romantic" in the first paragraph of the passage means______.
A.passionate
B.idealistic
C.quixotic
D.unrealistic
