试题答案:
A
答案解释:
解题思路: 本题考查介词的用法。根据题意“星期天的早晨,在这公园的一角通常很安静”。虽然题句中真正修饰的名词是mornings,但mornings前面加了个Sunday,变成特定某日期的早晨,故不能用介词in,而应该变成on,正确答案为A)选项。

3. Friction is a force which opposes motion. Much of the energy supplied to a complicated machine with many moving parts is wasted in overcoming this opposition. The energy is converted into useless heat. The amount thus lost can be considerably reduced and the life of the machine prolonged by careful lubrication. This reduction improves the efficiency of the machine. Another way in which friction is reduced is to substitute roller or ball bearings for the earlier type of bearing, in which the surfaces in contact move by sliding. Bearings of these later types are used very extensively in many kinds of modern machinery.It must not be assumed, however, that friction is always a disadvantage. In many instances it is highly important. Belts are often used in conveying power from one machine to another. In the absence of friction, this could not be done. The driving wheel would not run the belt, neither would the belt run the wheel to driver. Without friction, then, belted machinery could not be used. Again in the case of all motor vehicles, friction is essential in the operation of the brake. Were there no friction, there could be no brake. But even this illustration does not give an adequate picture of the importance of friction. The vehicle could not even be started if it were not for the friction exerted between the tires and the road. Nails hold in wood, and screws hold in either wood or metal by reason of friction, without which they would be useless. Walking is difficult enough on an icy pavement, but it would be wholly impossible if there were no friction at all between the shoe and the pavement.(5分)3.1 Friction arises when____.(1分)A. an opposing force of motion exists B. the energy is wastedC. everything is motionlessD. a complicated machine is supplied with energy

1. In 1637 the French philosopher-mathematician ReneDescartes predicted that it would neverBe possible to makeA machine that thinksAs humansDo. In 1950, theBritish mathematicianAndComputer pioneerAlan TuringDeclared that oneDay there wouldBeA machine thatDuplicate human intelligence in every wayAnd prove itBy passingA specialized test. In this test,AComputerAndA human hidden from view wouldBeAsked random identical questions, if theComputer were successful; the questioner wouldBe unable toDistinguish the machine from the personBy theAnswers.InspiredBy Turing's theory, the firstConference onAIConvenedAtDartmouthCollege in New Hampshire in 1956. SoonAfterwardsAnAI laboratory was startedAt Massachusetts Institute of TechnologyBy John McCarthyAnd Marvin Minsky, two of the nation's leadingAI proponents. McCarthyAlso invented theAIComputer language, Lisp;ButBy the early 1990sAI itself had notBeenAchieved. However, logic programsCalled expert systemsAllowComputers to "make,Decisions"By interpretingDataAnd selecting fromAmongAlternatives. TechniciansCan run programs used inComplex medicalDiagnosis, language translation, mineral exploration,And evenComputerDesign.MachineryCan outperform humans physically. So, too,CanComputers outperform mental functions in limitedAreas--notably in the speed of mathematicalCalculations. For example, the fastestComputersDevelopedAreAble to perform roughly 10BillionCalculations per second.But making more powerfulComputers will probably notBe the way toCreateA machineCapable of passing the Turing test.Computer programs operateAccording to set procedures, or logic steps,CalledAlgorithms (算法). InAddition, mostComputersDo serial processing: operations of recognitionAndComputationAre performed oneAtA time. TheBrain works inA mannerCalled parallel processing, performing operations simultaneously. ToAchieve simulated (模拟) parallel processing, some supercomputers haveBeen made with multiple processors to follow severalAlgorithmsAt the same time.Critics of thisApproach insist that solvingAComputationDoes not indicate understanding, somethingA person who solvedA problem would have. Human reasoning is notBased solely on rules of logic. It involves perception,Awareness, emotional preferences, values, evaluating experience, theAbility to generalizeAnd weigh options,And more. Some proponents ofA1 have, therefore, suggested thatComputers shouldBe patternedAfter the humanBrain, which essentiallyConsists ofA network of nerveCells.By the early 1990s, theClosestApproximation toAI wasA special siliconChipBuilt toBehave likeA humanBrainCell. It was modeledAfter the internal workings of neurons in the humanCerebralContext. Unlike theConventional silicon ship, which works inDigital mode, the new siliconChip works inAnalog mode, much the wayA humanBrainCell works.21. According to Turing,AComputerCan prove to have human-like intelligence inA special test if____A. theComputer givesBetterAnswersB. the questioner fails to give identical questionsC. the questionerCan't tellBetween theAnswers ofA personAndAComputerD. The questionerCan't find the person hiddenBy theComputer

24.Early in my travels, I had noticed these“new things” under the sun, and since they occur in increasing numbers all over the nation, it is interesting to observe them. From the beginning of my travels I had noticed the sale lots where they were sold and traded, but then I began to be aware of the parks where they sit down in uneasy permanence.By talking to the managers of the parks and to the dwellers in this new kind of housing, I got to know that these trailers are wonderfully built homes. Some of them are even forty feet long and they have two to five rooms, and are complete with air-conditioners, toilets, baths, and televisions. The parks where they sit are equipped with every facility. When a mobile home is drawn to the trailer park (活动住屋的停车场),water and electric power will be connected and the television antenna raised, and then the family settle down.The park men charge a small ground rent plus fees for water and electricity. Telephones are connected in nearly all of them simply by plugging in a jack (插座). Sometimes the park has a general store for supplies, if there are no supermarkets nearby. Parking difficulties in the towns have caused these trailers to move to the open country where they don’t have to pay town taxes. The fact that these homes can be moved does not mean that they do move. Sometimes their owners stay for years in one place. It is a totally new and appealing way of life to me. These homes are never cheap and often are quite expensive with all the thousand appliances we live by—dishwashers, automatic clothes washers and driers, refrigerators.(10分)24.1 The author noticed the “ new things” (Para.1)when .(2分)A. he worked in the countryB. he traveled on a sunny dayC. he traveled around the countryD. he tried to talk to manager in the park
