21、Many people in high school cannot wait to go to college and leave their hometown behind. Questions arise, though, when it comes to all of the decisions involved in choosing a college.
One of the first considerations may be finance. State and public colleges are often the least expensive. Often, though, the better colleges are private and more expensive. It is sad when gifted students cannot attend a college of their choice just for financial reasons.
Another major factor is location. Whether the college is in a small town or large city can have a major impact on its activities. A water lover probably will be more comfortable spending four years near an ocean or a lake. Those who cannot tolerate heat will probably be more comfortable at a northern college. Distance from home may also come into consideration. If family is a top priority, that person should stay close to home; on the other hand, if independence is desired, a campus farther from home would be more appropriate.
School size also plays a major role in the decision process. If you want to get to know your teachers, a small college is suitable. For those of you who consider yourself a “people person” and want a wide range of activities, a large college is more fitting. Your area of interest is another factor to consider in the decision-making process if you want to get the most from your education. The whole point of college is to learn what is of interest to you.
Crucially(至关重要地), one must take into consideration the colleges by which you can realistically be accepted. An Ivy League school for an average student would probably not be a good match. Similarly, an average school for an above-average student would not work well. The college should provide enough of a challenge for the student to work hard. Although there may not be the perfect college out there, there probably will be one that is close. Those who cannot find a suitable college are probably not looking hard enough.

A. financial situation is the first to consider

A. The location of a college.

22、Archimedes was a great scientist who lived in Greece long,long ago.He was so wise that even the king was his friend.
One day the king asked him,"How do you like my new crown?It's all gold."The king continued,"I gave a man gold to make this crown.But I think he may have kept some of it.”
“You are a wise man,”the king went on.“Find out if this crown is all gold.That way I will know if the man kept some of my gold.”
Archimedes thought about the crown for a long time.Then,one day he had an idea.He thought of it as he stepped into his bathtub.He saw that the water ran out over the sides.
"I've got it!"he yelled.He jumped out of his bathtub.He ran all the way to the king's home even without dress.
Archimedes asked the king for a piece of gold."It must be the same size as the one you gave the man,”he said. Then he filled a tub with water.In it he put the piece of gold.The water rose.He then took the gold out.He put the crown in the tub.The water rose even higher than before.That should not have happened!The crown and the piece of gold should have taken up the same space in the tub.Something had been added to the crown.It may have been silver. It may have been something else.But the crown was not all gold.
Archimedes’s idea was so clever that it is still used today.And he went on to learn many other things.But he sometimes got his ideas in strange places.

23、All evidence points to the fact that Mars once had flowing water, but numerous flybys, orbiters and landers have confirmed one undeniable fact — any liquid (液体的) water that was once on its surface is now long gone.
One idea, the Mars Ocean Hypothesis, suggests that Mars not only had some liquid water, but a lot of it. But the new study’s co-author Kun Wang says his team’s finding pours cold water on it.
“Mars’ fate (命运) was decided from the beginning.” Wang, an assistant professor of Earth and planetary sciences, said in a statement. That’s because the lower mass and gravity of Mars makes it easier for volatile (挥发) elements and compounds such as water to escape from its surface into space.
The researchers looked at 20 Martian meteorites (陨石) ranging in age from about 200 million years old to 4 billion years, dating back to a time when the solar system was still in the chaos of formation. The researchers analyzed water behaves in much the same way, indicating that most of it would have been lost to space during the formation of Mars.
The liquid water that did remain on the Martian surface carved out the riverbeds and other formations that we see there today, Wang says. But that water, too, would likely have disappeared had it not been trapped as ice at the Martian poles as the climate on the planet became colder, he notes.
“This does probably indicate a lower limit on size for a planet to be truly habitable,” Wang says, “Understanding that lower limit is important — there are lines of evidence that small planets are more common than big ones, so if the small ones are dry, then there are fewer habitable (适于居住的) worlds out there than we thought.”
【1】What is the function of the first paragraph?
A．To present an argument.
B．To make a comparison.
C．To reach a conclusion.
D．To explain a concept.
【2】Why is there little water on Mars according to Wang?
A．Water is too easy to dry out.
B．The cold weather froze the water.
C．Flybys consumed most of the water.
D．The gravity of the Mars can hardly lock water.
【3】What writing skill is used in Paragraph 4?
A．Comparing results.
B．Listing figures.
C．Giving examples.
D．Raising questions.
【4】Why are scientists concerned about water on the Mars?
A．We are in great need of water on earth.
B．They are trying to find suitable place for humans.
C．Mars is the destination to explore in the long run.
D．Mars is very significant for the health of the earth.
24、 One after another, telecommunications giants (通信巨头) have announced their latest fifth generation (5G) products. They have also claimed that 5G technology would be used on a massive scale by 2020. Yet, when reporting about 5G, many domestic media outlets have described it as a “much faster” technology than 4G without mentioning any of its other advantages. As a result, the common public view about 5G is that they could “download a high-density movie within one second”. Beyond that, most people know nothing about 5G.
Actually, 5G technology has many more advantages than 4G apart from speed. According to the criteria of 3GPP, an international standardization organization, 5G technology can be used for at least three purposes—for connecting everything, reliability of connections, and eliminating delays.
“Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible. 5G would enable one server to connect to multiple terminals (终端) and thus establish high-speed coordination among them, and help the chips inside the terminals to timely react to meet people’s needs. Take for example, autonomous vehicles, which are mature technology products. Self-driving cars combine a variety of sensors, such as radar, computer vision, and GPS to identify navigation paths and obstacles. 5G technology will link all the elements of a transportation system, such as traffic lights, cameras and, of course, cars to establish perfect coordination so they can avoid obstacles and move on navigation paths, which will help strengthen self-driving technology.
Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required. For instance, in certain surgeries, surgeons insert nano-robots inside a patient’s body and have to maintain constant control over the robots to ensure they perform their functions and do not cause any harm to the patient. This is an technology can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.
【1】What will the author most probably discuss in the paragraph that follow?
A.Eliminating delays. B.5G network capacity.
C.Disadvantages of 5G. D.Building 5G base stations.
【2】Which can also serve as an example of “connecting everything”?
A.Improvement of smart phone signals.
B.Decrease in telecommunication cost.
C.High speed in-playing computer games.
D.Online tests for all members at the same time.
【3】Why can 5G be used in fields with high safety standards?
A.It can attract most eyeball on a massive scale.
B.It can provide dependable and constant service.
C.It offers massive machine type of communication.
D.It employs 4G base stations and occupy less space.
【4】What would be the best title for the passage?
A.5G Technology: More Than about High Speed
B.5G Technology Will Shape the Future of Connectivity
C.Telecom Giants Work Together to Better 5G Technology
D.Advantages and Disadvantages of 5G Technology and Products
