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 foods
B.To identify the freezing point of water
C.To state the correct setting for a freezer
D.To give the temperature for blanching
Why does the author use the term expensive mistake in discussing blanching?A.To state that blanching is expensive but very effective
B.To warn that not blanching will harm the food’s nutritional value
C.To emphasize the importance of blanching only a few items at a time
D.To show that many people waste food by blanching improperly

Our house was directly across the street from the clinic entrance of John Hopkins Hospital in Baltimore. We lived downstairs and rented the upstairs rooms to out-patients at the clinic. One summer evening as I was fixing supper, there was a knock at the door. I opened it to see a truly awful looking man-no taller than my eight-year-old son-I thought as I stared at the shriveled (皱缩的) body. But the shocking thing was his face-twisted from swelling. He told me he'd been hunting for a room since noon but with no success." I guess it's my face…, but my doctor says with a few more treatments …" I told him we would find him a bed. When I had finished the dishes, he told me he fished for a living to support his daughter, her five children, and her husband, who was hopelessly disabled from a back injury. He didn't tell it by way of complaint; in fact, every other sentence began with a thanks to God for a blessing. He was grateful that no pain accompanied his disease, which was apparently a form of skin cancer. The next morning before he left for his bus, he asked if he could come back and stay the next time he had a treatment. I told him he was welcome to come again. In the years he came to stay overnight with us, there was never a time that he did not bring us fish or oysters or vegetables from his garden. When I received these little gifts, I often thought of a comment our next-door neighbor made after he left that first morning." Did you keep that awful looking man last night? I turned him away. You can lose roomers by accommodating such people!" Maybe we did lose roomers once or twice. But oh! If only they could have known him, perhaps their illnesses would have been easier to bear. I know our family always will be grateful to have known him; from him we learned what it was to accept the bad without complaint and the good with gratitude. |
