The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.
“If there is life on Mars, there is a good chance you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.
Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.
One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.
“I said: ‘Wow, that’s a cave’” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”
He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.
“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”
The caves probably formed when tube-shaped lave flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.
小题1:What does the passage mainly talk about?
A.How the caves were formed on Mars. | B.How scientists found these caves on Mars. |
C.Caves on Mars may be full of hot air or a sign of life. | |
D.Scientists have completely recognized the surface of Mars. |
A.water has already been found on Mars | B.the scientists found all the caves at night |
C.it is certain that there is life in these caves | |
D.the surface of Mars is bitterly cold, radiation-soaked and dry |
A.such caves could provide energy for life | B.they had finally found the caves on Mars |
C.such caves would be perfect places to hunt for life | |
D.scientists had long been looking for these caves |
A.lava and energy | B.water and radiation from space |
C.gases and lava | D.water and protection from radiation |
答案
小题1:C
小题2:D
小题3:B
小题4:D
解析
小题1:这是一道主旨题。本文主要介绍了科学家在火星上发现一些坑洞,这些坑洞可以聚集热空气和水分,使生命出现变得可能。本文也描述了这些坑洞发现的过程和形成原因,但都不是主要描述的内容,所以A项和B项不全面。
小题2:这是一道判断题。根据倒数第三段“He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked, dry surface.”可以判断出火星表面是个极端寒冷、充满辐射、干燥的地方。A、C选项都是文中的推测,并没有得出明确的结论。
小题3:这是一道推断题。根据第六段Dr.Clarke的表述“People have been looking for these for a long time;now we have found them.”可知Clarke教授的喜悦是因为人们找这些坑洞很长时间了,现在终于找到了。
小题4:这是一道归纳题。根据坑洞中可能出现生命以及倒数第二段“Tiny drops of water could collect inside,”和“A cave is also a protection from radiation”可以归纳出生命产生需要水和避免辐射。

举一反三
University tuition fees (学费) are currently capped at £3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.
In the research, the teenagers were presented with die terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average £ 31.000 by the age of 25, although the average salary for those aged 22 to 29 is just £ 17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than £ 10.000. Average debts for graduates are £ 12,363.
Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they arc to become responsible, forward-planning adults who manage their finances confidently and effectively."
Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweathcr. aged 15. from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money.
1. Which of the following can be found from the five-year research project?
A. Students understand personal finances differently.
B. University tuition fees in England have been rising.
C. Teenagers tend to overestimate their future earnings.
D. The students" payback ability has become a major issue.
2. The phrase "to raise the ceiling" in paragraph 2 probably means "______".
A. to raise the student loans B. to improve the school facilities
C. to increase the upper limit of the tuition D. to lift the school building roofs
3. According to Stephen Moir, students_______.
A. are too young 10 be exposed 10 financial issues
B. should learn 10 manage their finances well
C- should maintain a positive attitude when facing loans
D. benefit a lot from lessons on personal finance
4. What can we learn from the passage?
A. Many British teenagers do not know money matters well
B. Teenagers in Britain are heavily burdened with debts.
C. Financial planning is a required course at college.
D. Young people should become responsible adults.
Around him use. Bit by bit .he makes the necessary changes to make his language like other people"s. In the same way, children learn to do all the other things: they should learn to do without being taught, such as to walk, run, climb, whistle, ride a bicycle—compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to .Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(常规)work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer .Let the children learn what all educated persons must some day learn ,how to measure their own understanding, how to know what they know or do not know.
小题1:According to the passage ,the best way for children to learn things is by______
A.listening to skilled people"s advice |
B.asking older people many questions. |
C.making mistakes and having them corrected |

A job description should give details of the performance that is required for a particular job, and a job specification should give information about the behaviour, knowledge and skills that are expected of an employee who works in the position. When all of this has been collected, it is possible to make a training specification. This specifies(详细说明) that the training department must teach for the successful performance of the job, and also the best methods to use in the training period.
There are many different training methods, and there are advantages and disadvantages in all of them. Successful training performances depend on an understanding of the difference between learning about skills and training in using them. It is frequently said that learning about skills takes place “off the job” in classroom, but training in using these skills takes place “on the job,” by means of such activities as practice in the workshop.
It’s always difficult to evaluate the costs of a training programme. The success of such a programme depends not only on the methods used but also on the quality of the staff who do the training. A company can often check savings in time and cost by examining the work performed by the workers and technicians who have completed a training programme. The evaluation of management training is much more complex than that.
小题1: The writer mainly wants to tell us_____by the passage.
A. Why firms should pay attention to staff training |
B. Staff training must have a purpose |
C. Purposes and methods are most important in staff training |
D. How to evaluate a training programme |
A. the training contents and methods |
B. the cost and savings of the programme |
C. the performance required for a certain job |
D. the behaviour, knowledge and skills expected of an employee |
A. the purposes and the methods |
B. job description and job specification |

C.deal with | D.expect and believe |
I"m afraid I have some very bad news for you. I have been very naughty and the school principal is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.
The trouble started last night when I was smoking a cigarette in bed. This is against the rules, of course. We are not supposed to smoke at all.
As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away.
Unfortunately, the cigarette fell into the waste-paper basket, which caught fire. There was a curtain near the waste-paper basket which caught fire, too. Soon the whole room was burning.
The principal phoned for the fire department. The school is a long way from the town and by the time the fire department arrived, the whole school was in flames. Many of the girls are in the hospital.
The principal says the fire was my fault and you must pay for the damage. She will send you a bill for about a million dollars.
I am very sorry about this.
Much love, Sarah
P.S.
None of the above is true, but I have failed my exams. I just want you to know how bad things could have been!
小题1:Sarah wrote to her parent______
A. to inform them about an accident |
B. to ask them for money |
C. to them wonderful news |
D. to tell then she had failed her exams |
A.she wanted to make them worried |
B.she wanted them to have some fun |
C.she wanted to make them less angry at the real news |
D.she wanted to make them even more angry |
A.mostly true | B.partly true |
C.all true | D.completely untrue |
A.she had failed her exams |
B.it was her fault that the fire had broken out |
C.she not make the phone call in time |
D.she had caught her smoking in bed |
Then we worked out a plan: When Christie takes one of her children out, I’ll watch her other three. And when she watches two of mine, I’ll take someone out.
The children were extremely quick to accept the idea of “Mommy and Me” time. Christie’s daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. “She’s like a different child when there’s no one else around,” Christie shared with me quickly. With her mother all to herself, McKenzie didn’t have to make an effort to gain attention.
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering(口吃的)son, Tom, doesn’t stutter once during our activities since he doesn’t have to struggle for a chance to speak. And the other son, Sam, who’s always a follower when around other children shines as a leader during our times together.
The “Mommy and Me” time allows us to be simply alone and away with each child ---talking, sharing, and laughing, which has been the biggest gain. Every child deserves(应得到)to be an only child at least once in a while.
小题1:What is the text mainly about?
A.The experience of the only child being with mother. |
B.The advantage of spending time with one child at a time. |
C.The happy life of two families. |
D.The basic needs of children. |
A.happy | B.curious | C.regretful | D.friendly |
A.The daughter acts like a leader. | B.Sam holds her hand more often. |
C.The boys become better followers. | D.Tom has less difficulty in speaking. |
A.having brothers and sisters is fun | B.it’s tiring to look after three children |
C.every child needs parents’ full attention | D.parents should watch others’ children |
