未知题型 The discovery of freezing has changed our eating habits more than any other related invention. Because many foods contain large amounts of water, they freeze solidly at or just below 32 degrees Fahrenheit. When we lower the temperature to well below the freezing point and prevent air from penetrating the food, we retard the natural process of decay that causes food to spoil. Freezing preserves the flavor and nutrients of food better than any other preservation method. When properly prepared and packed, foods and vegetables can be stored in the freezer for one year. Most vegetables and some fruits need blanching before they are frozen, and to avoid this step would be an expensive mistake. The result would be a product largely devoid of vitamins and minerals. Proper blanching curtails the enzyme action, which vegetables require during their growth and ripening but which continues after maturation and will lead to decay unless it is almost entirely stopped by blanching. This process is done in two ways, either by plunging vegetables in a large amount of rapidly boiling water for a few minutes or by steaming them. For steam blanching, it is important that timing begin when the water at the bottom of the pot is boiling. Different vegetables require different blanching times, and specified times for each vegetable must be observed. Under-blanching is like no blanching at all, and over-blanching, while stopping the enzyme action, will produce soggy, discolored vegetables. Why does the author mention 32 degrees Fahrenheit?A.To suggest the storage temperature for most foodsB.To identify the freezing point of waterC.To state the correct setting for a freezerD.To give the temperature for blanchingWhy does the author use the term expensive mistake in discussing blanching?A.To state that blanching is expensive but very effectiveB.To warn that not blanching will harm the food’s nutritional valueC.To emphasize the importance of blanching only a few items at a timeD.To show that many people waste food by blanching improperly请帮忙给出每个问题的正确答案和分析,谢谢!
未知题型 The house style that dominated American housing during the 1880s and 1890s was known as Queen Anne, a curious name for an American style. The name was, in fact, a historical accident, originating with fashionable architects in Victorian England who coined it with apparently no reason other than its pleasing sound. The Queen Anne style was loosely based on medieval structures built long before 1702, the beginning year of Queen Anne’s reign. A distinctive characteristic found in most Queen Anne houses is the unusual roof shape --- a steeply pitched, hipped central portion with protruding lower front and side extensions that end in gables. It is often possible to spot these distinctive roof forms from several blocks away. Another feature of this style is the detailing, shown in the wood shingle siding cut into fanciful decorative patterns of scallops, curves, diamonds, or triangles. Queen Anne houses are almost always asymmetrical. If you draw an imaginary line down the middle of one, you will see how drastically different the right and left sides are, all the way from ground level to roof peak. A final characteristic is the inviting wraparound porch that includes the front door area and then extends around to either the right or left side of the house. Queen Anne houses faded from fashion early in the twentieth century as the public’s taste shifted toward the more modern Prairie and Craftsman style houses. Today, however, Queen Anne houses are favorite symbols of the past, painstakingly and lovingly restored by old-house buffs and reproduced by builders who give faithful attention to the distinctive shapes and detailing that were first popularized more than one hundred years ago. Why does the author use the word curious in describing the name of an American style?A.The style was invented before Queen Anne’s reign.B.The name was accidentally misspelled.C.The style was more popular in Victorian England.D.The name did not originate in American.The word it in paragraph 1 refers toA.styleB.nameC.accidentD.EnglandWhich of the following is NOT mentioned as a characteristic feature of Queen Anne houses?A.decorative windowsB.wood shingle exterior wallsC.large porchD.steeply pitched roofWhich of the following can be inferred from paragraph 2 about the Queen Anne style?A.the Queen Anne style combined several other styles.B.the Queen Anne style had to be built in the city.C.the Queen Anne style was elaborate and ornate.D.the Queen Anne style was not very popular.The word buffs in paragraph 3 is closest in meaning toA.expertsB.sellersC.criticsD.painters请帮忙给出每个问题的正确答案和分析,谢谢!
