19．His aim is to be a successful writer．

分析 他的目標是成為一名成功的作家．

解答 答案：aim
此處用在形容詞性的物主代詞His之后，在句中作主語，應(yīng)使用名詞形式；根據(jù)句意以及首字母的提示可知，這里指的是：（他的）目標，故用名詞aim的某種形式；由于謂語動詞is為第三人稱的單數(shù)形式，故填aim．

點評 本題考查了名詞的用法；做類似的題時，應(yīng)根據(jù)句意及分析句子的結(jié)構(gòu)，并結(jié)合首字母的提示，判斷出需要填寫的單詞；在確定了此處應(yīng)填名詞之后，還應(yīng)考慮到名詞的單復(fù)數(shù)形式；因此在平時的學(xué)習(xí)中，應(yīng)牢固記憶單詞的拼寫；并且熟練掌握一些的語法知識．

18．Popeye the Sailor first became a popular cartoon in the 1930s．The sailor in that cartoon ate lots of spinach to make him strong．People watched him，and they began to buy and eat a lot more spinach．Popeye helped sell 33 percent more spinach than before!Spinach became a necessary part of many people's diets．Even some children who hated the taste began to eat the vegetable．
Many people thought that the iron in spinach made Popeye strong，but this is not true．Spinach does not have any more iron than any other green vegetable．
People only thought spinach had a lot of iron because the people who studied the food made a mistake．In the 1890s，a group of people studied what was inside vegetables．This group said that spinach had ten times more iron than it did．The group wrote the number wrong，and everyone accepted it．
Today，we know that the little iron that is in spinach cannot make a difference in how strong a person is．However，spinach does have something else which the body needs-folic acid．
It is interesting to point out that folic acid can help make a person strong．Maybe it was really the folic acid that made Popeye strong all along．

A．Popeye the Sailor
