  At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight.They dim immediately when it's sunny and brighten when a passing cloud blocks the sun.

  A wall of windows at a University of Pennsylvania engineering building has built-in blinds(百叶窗)controlled by a computer program that follows the sun's path.Buildings are getting smarter and the next generation of building materials is expected to do even more.

  Windows could catch the sun's energy to heat water.Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up.

  Many new materials and technology have been designed in the last 15 years.They are now being used in a wave of buildings designed to save as much energy as possible.They include old ideas, like “green roofs”, where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out.

  As technologies such as sensors become cheaper, their uses spread.

  The elevators(电梯)at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops.People who work in the building will enter it by swiping(刷)ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use.The building also has windows with a coating that blocks heat while letting in light.

  More new building materials and technology are in development.A Philadelphia building firm is now working on “smart wrap” that uses tiny solar collectors to catch the sun's energy and transmitters(传输器)as wide as a human hair to move it.They are expected to change the face of the construction industry in the next ten years or so.

阅读下面短文,从每题所给的四个选项(A,B,C和D)中选出最佳选项。

  Many new students find it hard to do all the study that has to be done; they find themselves putting off reading assignment(作业) , jumping from one subject to another and rarely being quite certain what they are trying to do during a particular study session (期间) . The best way to overcome these difficulties and to start studying efficiently (高效地) is to plan your time and organize your work. Let us suppose that you have 15 hours per week of classes and that you decide to allow yourself a 40-hour-working week (a reasonable figure, leaving you 70 waking hours for other activities).

  You now have to decide how to divide the remaining 25 hours of private study. Naturally the decisions you make will change from week to week according to what essays have to be written and what reading has to be done. Many people find it helpful to draw up each week a seven-day-timetable showing the occasions on which they will be working privately and the particular subjects that they will be studying on each occasion. By checking such a plan at times during the week, you can see what you have done and what you have still to do: the whole plan becomes more manageable. There are a number of places where you can study—college library, public library, home, empty classrooms, on bus or train—and each has several obvious advantages and disadvantages. The college library is least busy in the evening, on Wednesday afternoon, and all day Friday and Saturday.

  When you are deciding where to study, keep the following suggestions in mind:

  1.Try to study always in the same place. After a while the familiar surroundings (环境) will help you to switch into the right frame (框架) of mind as soon as you sit down.

  2.Find somewhere with as few distractions (干扰物) as possible.

  3.Make sure that your study place has a good light and is warm (but not too warm) and well aired.

1.Many new students find it hard ________.

[  ]

A.to delay their reading
B.to make a good plan
C.to study efficiently
D.to jump from subject to subject

2.What's the main idea of the passage?

[  ]

A.Find a quiet place for study.
B.Plan your time and organize your work.
C.Overcome your difficulties.
D.Be sure what you can do.

3.A student's organization of his work will need to change according to ________.

[  ]

A.what he has to write and read that week
B.how marry hours he is awake
C.how many lectures he misses
D.how many subjects are required

4.A student is advised to make a weekly plan and to check it from time to time in order to ________.

[  ]

A.see what day of the week it is
B.see how he feels for the whole week
C.see whether he has calculated it properly
D.see what work still needs doing

Stepfamilies are commonplace in the United States and their number continues to grow. While stepfamilies differ widely in their make-up, they all consist of a parenting couple and children, one or more of whom is of a previous union. Such combinations of his kids, her kids, and then, possibly, kids of the new union make for complicated and often trying difficulties, more challenging than those of traditional families.

Since stepfamilies involve more people and, consequently, more potential problems from the start than do childless new marriage, it is wise for the couple to do some careful planning prior to (=before) marriage. Not only do the prospective(预期的) marital partners need agreement about their own carriers, life goals, finance and special interests, they must also prepare for new relationship with their children and attempt to accommodate their individual needs and feelings. Furthermore, there are often the rights of other relatives to consider.

As for any family, the basic ingredient(成分) of a successful stepfamily are affection, kindness and mutual(相互的) respect. However, love alone is not enough. Certainly love is the cornerstone upon which the foundation of any family is built, but there are also many other important ingredients involved in building a successful stepfamily.

Surveys reveal that successful families regard the ability to communicate openly as the most important factor in their success. Communication is what keeps families on track and functioning as a unit. Although healthy communication is easier for some people than for others, this skill can be learned and improved. Healthy communication involves speaking clearly and listening carefully.

By their very nature, stepfamilies often are complicated by past events that give rise to ambivalent(矛盾的) loyalties, lingering(持久的) hurts, fears, feelings of guilt and unrealistic dreams. The difficulties that arise within the stepfamilies are human and understandable. However, there are ways to confront(面临) and resolve them. For example, support groups and professional counselors(法律顾问) are available in most communities to provide help and guidance when communications stopped and problems seem overwhelming(压倒性的).

Planning and building a stepfamily is not a responsibility to take lightly. It can be a very trying and, at times, seemingly impossible effort. Many potential troubles can arise and threaten to destroy the stepfamily. Nevertheless, meeting and mastering these special challenges can bring unexpected satisfactions and rewarding depths of family closeness and affection.

1.According to the passage, there are      in the United States.

A.no stepfamilies

B.more stepfamilies than ever before

C.fewer stepfamilies than ever before

D.fewer stepfamilies than traditional ones

2.Which of the following can help avoid the potential problems arising in a stepfamily?

A.The pursuit of the same careers.

B.Professional interventions(干涉).

C.The development of special interests.

D.Careful planning before the marriage.

3. Many people believe that      contributes most to the building of a successful stepfamily.

A.everlasting loyalties

B.open communication

C.kindness and mutual respect

D.persistent(持久稳固的) affection

4. It is natural for a stepfamily to be     .

A.unrealistic

B.complicated

C.ambivalent

D.guilty

5.According to the author, planning and building a stepfamily is     .

A.impossible            

B.satisfying and rewarding

C.discouraging and frustrating

D.a difficult and trying experience
