Questions下列各are based on the following passage. How many times have you heard the expression that most people spend more time planning their vacation than they do planning their lives？ .I would 36 that expression by adding that most people spend more time "thinking" about their vacation than they do thinking about whats important in their life. While rest and relaxation are a must in living a 37 life, its not what we were created to do. After all, the Master Creator took his R&R (Rest and Recreation) on the seventh day, only after six days of "definitely directed thought". Wallace D. Wattles wrote, "There is no labor from which most people shrink as they do from that of sustained and 38 thought; it is the hardest work in the world. " And yet it is the first and primary labor of 39 My friend Mike Lit man wrote an outstanding article for his ezine (电子杂志) this week. Its called"The Millionaire Composite (合成物)" and it 40 one of the big differences between super successful people and everyone else. He writes, "I recently visited with a Real Estate Multi Millionaire Mogul (大人物). What did I see next to his desk？ His vision statement, along with a list of what he values in life－hand written. " "A few months back, I interviewed an individual who has sold over a billion dollars worth of products on television. He told me that he reads his life and business vision and goals dally, and that he TAKES TIME to 41 exactly what he wants to create--EACH NIGHT before falling asleep. " What is your lifes purpose or your personal mission statement？ Is it written down？ Do you review it and think about it often？ Is your life organized around your purpose and a set of goals that support that purpose？ Without purpose and goals--defmitely directed thought--you are like the 42"ship without a rudder (舵) , 1here is power m your purpose and in your goals. It is the power that takes you over obstacles, the fuel that 43. you toward the life you envision. One of my favorite passages of James Allen is one he wrote in "The Mastery of Destiny" :"All successful people are people of purpose. They hold 44 to an idea, a project, a plan, and will not let it go; they cherish it, brood upon it, tend and develop it; and when assailed by difficulties, they refuse to be beguiled into surrender; indeed, the intensity of the purpose increases with the growing 45 of the obstacles encountered. " And thats-worth thinking about.

A、The rank of an m×n matrix A is equal to the number of nonzero singular values of A, where singular values are counted according to multiplicity.
B、If A is an n×n matrix, then A and AT have the same eigenvectors.
C、If A is symmetric, then eA is symmetric positive definite.

| The opinion of many engineers is that the architects that designed the New York World Trade Center Twin Towers did a good job in designing the buildings. The buildings were safe from the hazards envisioned (预想到的) at the time. Indeed, they were designed to withstand the force of aircraft that might crash into them. They were not however, designed to withstand the effects of the very high temperatures produced by the ignition (点燃) of aviation fuel carried by the aircraft. Steel lightly covered with concrete is the main structural part of the towers and steel loses a lot of structural strength when heated to 1100 degrees Centigrade and beyond, as it was. To protect the steel the towers beams were coated with a few centimeters of concrete. That insulation (隔离) was to provide structural state of being complete for at least 1 hour of fire. The towers met that test. The south tower lasted 62minutes. The north, 103 minutes. Tragedy followed when not all could escape before the collapse. Most experts agree that the Twin Towers were very well designed. Many also agree that the people planning the attacks were very knowledgeable and aimed the aircraft at a height that would produce the most damage. The aircraft crash and the resulting fuel fed fires were aimed at about the 90th floor. That was just high enough to insure that the upper floors would weaken with the heat and crack down, dropping into the remaining part of the building. The mass of the falling top floors created such a falling load that some experts estimate it exceeded by 5 to 10 times normal bearing loads. The effect was like a giant hammer, each floor contributing more weight to be born by the next floor down. Were the Trade Towers well designed？ Engineers say yes. But, the public holds to the belief that architects will never again design a tall building without considering the effects of terrorist attacks of all potential kinds. That not only includes the ability of the structure to withstand attack but the means to allow the buildings occupants to escape in time to survive. |

| A. it could withstand aircraft crashing into it at the moment B. it could withstand any natural hazards such as earthquake or fire C. it had an attracting and beautiful appearance until they were destroyed D. they had the miserable honor of being selected as the target of terrorist attack |
| 2. According to the article, those who designed the tower could have done better if _______. |
| A. the tower lasted longer after being attacked B. the tower held stable until all of the people in there managed to escape C. the tower can be immune to such attacks D. they considered more about the effects of the very high temperatures and made duel(决定性的) changes in the structure |
| 3. The part of the building below 90th floor _____________. |
| A. remained where they were B. cracked down because of the burning C. was hammered down by the falling upper part D. was safe after the attack |
| 4. The author believed that the Twin Towers ____________. |
| A. were not well- designed B. were well-designed C. were good examples for engineers of our time D. were out of consideration when we talk about engineering later |
