In diet-obsessed America, it’s hard to say an encouraging word |
|
|
about lipids—a term biochemists use to include all fats and oils. Yet |
|
|
life would be utterly impossible without them. Cell membranes, as we |
|
|
have seen, depend critically on a two-ply lipid layer to keep out |
|
5 |
unwanted elements. The insulating sheaths of nerve cells are built |
|
|
from fats, which is one reason why growing babies with rapidly |
|
|
developing nervous systems need a fair amount of fat—and why |
|
|
breast milk contains so much of it. Fat makes up only 12 percent of |
|
|
a newborn’s weight, but increases to nearly 30 percent by the end of |
|
10 |
a child’s first year. Fats also help generate a number of important |
|
|
hormones collectively called steroids—compounds structurally |
|
|
related to cholesterol—such as estrogen and testosterone. Of |
|
|
course, they also make effective padding to keep you warm and to |
|
|
cover vulnerable body parts such as the kidneys. |
|

Although physicians recommend that adults rely on lipids for no |
|
|
more than 20 percent of their daily intake, most Americans eat a lot |
|
|
more fat—chiefly from meat, eggs, cheese, assorted fried “junk |
|
|
foods,” and various plant sources such as nuts, peanut butter, and |
|
|
vegetable oils. Dietitians now recommend that men have 15 percent |
|
20 |
body fat by weight, and women no more than 20 percent, although |
|
|
social custom has dictated spectacularly different ratios over the |
|
|
centuries. Many cultures have regarded female plumpness as a sign |
|
|
of fertility—for the excellent reason that conspicuous body fat |
|
|
suggests that a woman has a good supply of nutrients to feed a fetus |
|
25 |
and nurse a newborn. |

英銘老師：閱讀測驗是很多考生畏懼的英文題型之一，其實閱題測驗的的解題並不難，因為外國人寫文章都愛用破題法，只要看第一段即可知道文章大概在講什麼內容。例如在此篇文章的第一段中，有提到“lipid” (脂質)、“fat” (脂肪)、“oil” (油)，所以文章一定跟“食物中的脂質”有關。
第1題：第1段的主旨是什麼？整段文章都是在講fat(脂肪)，所以答案是(D)。
補充：
rid v. 擺脫 (always)
I must get rid of the trouble.
我必須擺脫麻煩。
