Generally, however, modern examinations are written. The written examination, where all students are 2 on the same questions, was probably not known until the nineteenth century. Perhaps it appeared with the great 3 in population and the development of modern 4 . A room full of candidates (投考者) for a state examination, 5 exactly by electric clocks and carefully 6 over by 7 , resembles (类似于) a group of workers at a car factory. Certainly, during examinations teachers and students are expected to act like 8 .

    Two types of tests are commonly used in 9 schools. The first type is called an“objective test”. It is intended to deal with 10 , not personal 11. On objective tests the student has just one 12: he must 13 the correct answer and 14 its letter (or number) on his examination paper. Sometimes there is an answer sheet on which the four letters are 15 . Then the student has only to circle the one that 16 with the correct answer.

    For 17 some kinds of learning, however, such a test is not very 18 . A lucky student may 19 the correct answer without really 20 the material.

    So most teacher use another kind of examination in addition to objective tests.

    He had a big 3 , and usually enjoyed driving it long distances, but he was also quite 4 to go by train sometimes, especially when the weather was 5 . He was a little frightened of driving in the rain or snow, and it was 6 tiring to sit comfortably in a train and look out of the windows without being worried about how one was going to get to the next place.

    While he was walking to the taxi stand, he said to a local man who was also 15 there,“As this is my 16 visit to this part of the country and I was in too much of a hurry to find out about hotels before I 17 home, I would very much like to know how many you have here.”

    The local man answered,“We have two.”,

    “And which of the two would you 18 me to go to?”Mr. Gray asked then.

    The local man scratched (搔) his 19 for a few moments and then answered,“Well, it’s like this, 20 one you go to, you’ll be sorry you didn’t go to the other.”

    It is a pleasure to 1 someone who is down-to-earth is easy to talk to and 2 other people as equals. A down-to-earth person is just the 3 of someone who acts important or proud.

    Down-to-earth persons may be important members of 4 , of course. But they do not let their importance “ 5 to their heads”. They do not consider themselves to be better persons than 6 of less importance. Someone who is filled with his own importance and pride,  7 without cause, is said to have “his nose in the air”. There is 8 way a person with his nose in the air can be down-to-earth.

    Americans 9 another expression that means almost the same as“down-to-earth”. The expression is “both-feet-on-the-ground”. Someone 10 both feet on the ground is a person with a good 11 of reality. He has what is called“common sense”. He may have dreams,  12 he does not allow them to block his knowledge of 13 is real.

    The opposite kind of 14 is one who has “head in the clouds”. A man with his head in the clouds is a 15 whose mind is not in the real world.

    16 such a person can be brought back to earth. Sharp words from teacher can usually 17 a daydreaming student down-to-earth.

    Usually, the person who is down-to-earth is very 18 to have both feet on the ground.  19 we have both our feet on-the-ground, when we are down-to-earth, we act honestly and openly 20 others. Our lives are like the ground below us, solid and strong.

    A phone virus programmer can 1 your phone do things you have no control over, computer security experts 2 .

    It might 3 the White House or the police, or forward your personal address book to a marketing company. Or it could simply eat into the phone’s operating software, turning it 4 and erasing your personal information.

    Similar viruses have already made mobile phone owners 5 in Japan and Europe.

    Ari Hypponen, chief technical officer of a computer security company in Finland, said a virus “can get your 6 and send them elsewhere. And it can record your 7 .”

    Mobiles are now able to surf the Net, send emails and 8 software. So they are an easy 9 for the same hackers who have sent viruses to computers over the past decade.

    “It’s technically 10 now,”said Stephen Trilling, director of research at anti—virus 11 maker Symantec Corp based in the US.

    “If the phone is connected to the 12 , it can be used to transmit threats and 13 targets, just as any computer can.”

    In Japan, if you opened a certain email message 14 your mobile, it would cause the phone to repeatedly 15 the national emergency number.

    So phone operators had to 16 emergency calls until the 17 was removed.

    In Europe, mobiles’ short message service, 18 SMS, has been used to send codes that could damage phones.

    Mobile users can 19 viruses, of course, by sticking to their traditional phones 20 Web links, some experts said.

    But it is not easy now to find work, “ 5 you speak the language of the country well, there will be very few openings,”says Anthea Ellis, an adviser on 6 for students.“If you work with a family in Italy, you’ll have to speak Italian. When you wash dishes in a restaurant in Paris, the owner will expect you to speak 7 .British students only have a language 8 for jobs in the USA and Australia.”

    9 enjoys the experience. Sarah James was employed to help forty American children in Europe. The two teachers with the children had never been 10 . One child lost his passport; another became seriously ill and was 11 home; the whole group was thrown out of one hotel because of the 12 they made, and Sarah herself was robbed on her only 13 evening of the entire trip.“I did visit a lot of new places,”she says,“but it wasn’t worth it. The pay was 14 and it really was a 24-hour-a-day job. The kids never slept!”

    “The trouble is, students expect to have 15 time of it,”Anthea Ellis points out.“ 16 , they see it as a holiday. In practice, 17 , you have to work hard. At the same time, all vacation work is casual (临时) work. You’ll have a job when the hotel, the restaurant or the campsite is busy. 18 , you’ll work if it’s convenient for the company that employs you. But you have 19 employment rights. As soon as the holiday season  20 , they’ll get rid of you.”

    For two days it was raining without stopping. By the third night, it wasn’t raining at all. I gave the sign to the announcer, and the band began playing my music.

    The animals went through their tricks, but they were far from being 3 about the wetness.

    And so we came to the head-in-mouth 4 . When I pulled Leo’s mouth open, raising his face and nose to the 5 , I noticed that the muscles of his jaws were tense. Then, as I put my head in, a rain began pouring down. I felt Leo become 6 all over.

    My head was in now. I counted to ten and then gave him the tap on jaw 7 to let me go. But this time 8 happened.

    I awoke with an oxygen mask (氧气罩) 15 my face, and a doctor was working over me. “You’re lucky,”said the doctor,“as soon as you went faint (晕倒), the lion 16 you. For nearly three minutes you had no heart-beat !”

    By then it had stopped raining. I called Leo back and 17 his jaw.“Don't be a fool!”the doctor said, 18 I put my head in and counted to ten. Then I gave Leo the tap on jaw, and he obeyed immediately.

Curiosity is 3 silly or wrong. Some persons with nothing to do are 4 of curiosity about what their neighbors are doing. They are 5 to know what they are eating or drinking, what they are bringing or taking home or 6 they have come home so early or late. To be interested in these things is7 because they are not at all important. It is none of their 8 to know what neighbors do or are doing. Such curiosity is9not only foolish but also harmful. For most probably, it 10 to small talk which often brings11 , shame or disrespect to others, and thus hurt their feelings.

On the other12 , there is a noble curiosity—the curiosity of the wise, who 13at all the great things and try to find out all they 14 about them. Columbus could15 have found America if he had not been16 . James Watt would have not made the steam engine17 his curiosity about the raising of the kettle lid. All the great discoveries and inventions in human history have been made18 a result of curiosity. 19 the curiosity is never about unimportant things, which have20or nothing to do with the happiness of the public.
