A friend of mine had this problem and handled it in the most tactful (得体的) way I've ever seen. Instead of telling her admirer directly, she devoted herself to introducing him to every girl she knew. Whenever she had a date with him, she arranged to drop in at the home of one of her girl friends. At last he clicked (一见如故) with one of these girls, and then everyone was happy. My friend was rid of a problem and she still had the young man as a friend, which was just what she wanted him to be.
Of course this solution may not work for you. You may have your own way of dealing with the problem. But whatever you decide to do, keep one thing in mind—the boy in question has feelings every bit as sensitive as your own. So try to find a way of discouraging him without hurting him.
The best title for this passage would be______.
A．How to Make a Friend
B．Problems of Dating
C．Good Advice for Girls
D．How to Free Yourself from an Admirer

The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion(拥挤). One proposed solution to this problem is the automated highway system.
When the auto enters the highway system, a retractable(可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements.
The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wak for the buzzer(蜂鸣器) that will warn of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,400 to 2,000 vehicles that can be carried by a present-day highway.
One significant improvement in the future car may probably be ______.
A．its power source
B．its driving system
C．its monitoring system
D．its seating capacity

Chokwe Selassie is on a mission to help drivers avoid potholes(路面坑洼). The eighth-grader was inspired to kick off his mission on a recent morning, when his mother was driving him to school. Their car was damaged as it went over a huge pothole in the middle of the street in their hometown of Jackson, Mississippi. "I decided I was going to do something about the pothole prob-lem in my city," Chokwe says. His solution: an app(手机应用) that warns drivers when there is a pothole ahead.
Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. "When the app detects a potheole, it is highlighted(突出显示) in red," Chokwe says. "And if you get close to the pothole, your phone will warn you. " Drivers can also use the app to report any pot-holes" they encounter, and to look for other routes they can take to avoid roads that have them.
The app relies on Current available information about the streets of Jackson. "It works by u-sing the city&39; s 311 call system, so it uses information already stored in a database," Chokwe says.
(79) Through the call system, citizens dial 3-1-1 to report non-emergency problems--whiCh in-clude potholes. Chokwe and his friends determined that focusing on the 10 busiest streets in Jack-son would give them a large enough sample size to test the prototype(原型).
(80) Although the app isn&39; t yet available for sale, Chokwe is already looking for ways to im-prove it. The prototype remains limited&39;to 10 streets in Jackson, but he hopes to add more, so that it includes every street in the city. And then he wants to go even farther. "I want to keep working on the app until it&39; s nationwide," Chokwe says.
Which of the following is the best title for the passage？
A.A Solution to Traffic Jams
B.An App to Detect Potholes
C.Pothole Problems in Big Cities
D.Poor Road Conditions
The phrase kick off in Paragraph 1 is closest in meaning to__________.A.leave
B.invent
C.begin
D.shift
People use the 311 call system to report__________.A.emergencies
B.terrorist attacks
C.non-emergencies
D.child abuse
The prototype focuses on __________ streets in Jackson.A.10
B.15
C.20
D.25
According to the passage, which of the following statements is TRUE？A.Chokwe developed the app all by himself.
B.People can buy this app from the online store.
C.His mother' s car was once damaged over a pothole.
D.The app works by using the city's 911 call system.

The restrictive laws that the courts are interpreting are mainly a legacy of the bank failures of the 1930s. The current high rate -- higher than at any time since the Great Depression -- has made legislators afraid to remove the restrictions. While legislative timidity is understandable, it is also mistaken. One reason so many American banks are getting into trouble is precisely that the old restrictions make it hard for them to build a domestic base large and strong enough to support their activities in today's telecommunicating round-the-clock, around-the-world financial markets. In trying to escape from these restrictions, banks are taking enormous, and what should be unnecessary, risks. For example, would a large bank be buying small, failed savings banks at inflated prices if federal law and states' regulations permitted that bank to expand through the acquisition of financially healthy banks in the region7 Of course not. The solution is clear American banks will be sounder when they are not geographically limited. The House of Representative's banking committee has shown part of the way forward by recommending common-sensible, though limited, legislation for a five-year transition to nationwide banking. This would give regional banks time to group together to form. counterweights to the big money-center banks. Without this breathing space the big money-legislation should be regarded as only a way station on the road towards a complete examination of American's suitable banking legislation.
The author’s attitude towards the current banking laws is best described as one of _______.
A．concerned dissatisfaction
B．tolerant disapproval
C．uncaring indifference
D．great admiration

The restrictive laws that the courts are interpreting are mainly a legacy of the bank failures of the 1930's.

One reason so many American banks are getting into trouble is precisely that the old restrictions make it hard for them to build a domestic base large and strong enough to support their activities in today's telecommunicating round-the-clock, around-the-world financial markets.

第10题
Research experience is an essential element of hearing and promotion at a research university because it is the emphasis on research that distinguishes such a university from an arts college. Some professors, however, neglect teaching for research and that presents a problem.
Most research universities reward outstanding teaching, but the greatest recognition is usually given to achievements in research. Part of the reason is the difficulty of judging teaching. A highly responsible and tough professor is usually appreciated by top students who want to be challenged but disliked by those whose records are less impressive. The mild professor usually gets high overall ratings, but there is a sense of disappointment on the part of the best students. Thus, a university trying to promote professors primarily on the basis of teaching qualities would have to confront this confusion.
As modern science moves faster, two forces are exerted on professors: one is the time needed to keep up with the profession; the other is the time needed to teach. The training of new scientists requires outstanding teaching at the research university as well as the arts college. Although scientists are usually made in the elementary schools, scientists can be lost by poor teaching at the college and graduate school levels. The solution is not to separate teaching and research but to recognize that the combination is difficult but vital. It is time for universities to reserve the title of professor for those willing to profess, willing to be an earnest part of the community of scholars. Professors unwilling to teach can be called "distinguished research investigators." or something else.
The pace of modern science makes it increasingly difficult to be a great researcher and a great teacher. Yet many are described in just those terms. Those who say we can separate teaching and research simply do not understand the system, but those who say the problem will disappear are not fulfilling their responsibilities.
What point does the author intend to put across in the first paragraph？
A．Teaching and research are two contradictory fields.
B．Research can never be overemphasized.
C．The relationship between research and teaching should not be simplified.
D．It is not right to overestimate the importance of teaching.
