All children in the United States have to receive an education,but the law does not say they have to be educated at school.A number of parents prefer not to send their children to school.46 There are about 300，000 home-schoolers in the United States today.Some parents prefer teaching their children at home because they do not believe that public schools teach the correct religious values,others believe they can provide a better educational experience for their children by teaching them at home.47

David Guterson and his wife teach their three children at home.Guterson says that his children learn very differently from children in school.48 For example,when there is heavy snowfall on a winter day,it may start a discussion or reading about climate,snow removal equipment,Alaska,polar bears,and winter tourism.Or a spring evening when the family is out watching the stars is a good time to ask questions about satellites and the space program.49

Home schooling is often more interesting than regular schools,but critics say that home-schoolers are outsiders who might be uncomfortable mixing with other people in adult life.50 However,most parents don't have the time or the desire to teach their children at home,so schools will continue to be where most children get their formal education.

解每道題時只需要閱讀該題所在段落，不需要閱讀其他段落。往往通過閱讀該題目的前后句就能夠確定答案。

1.利用轉折關系來做題。

對于46題，我們可以閱讀其前面兩句話可知，法律沒有規(guī)定孩子們必須在學校里接受教育，這句話的潛臺詞就是有一些孩子沒有在學校里接受教育，那么他們在哪里接受教育呢？那么就學生而言，at school相對應的應該是at home，所以選D.

2.利用歸納總結關系來做題。

對于47題，出現在第一段的末尾。在這一段中，一直在對比在學校里接受教育和在家里接受教育，作為總結句，應該對這兩種教育形式的優(yōu)劣作出對比總結。在六個選項中，只有A和E提到了這兩種教育形式，但只有A正確，其中的results暗示了正確答案。

3.利用總分關系來解題。

對于48題，從例證詞for example我們就可得知，48空中必須出現一個具有概括意義的名詞而且這個名詞必須包括For example后所舉的例子。通過閱讀48題后面的句子：冬天下雪時他們與孩子討論有關氣候問題與除雪設備，討論阿拉斯加、北極熊、冬季旅游等話題。在春天的夜晚，舉家出去看星星，然后問孩子一些有關衛(wèi)星、太空項目等方面的問題。這些講的是孩子感興趣的話題，因此正確答案選C.

4.利用并列關系解題。

對于49題，應當是48題的延續(xù)。49題作為第二段的最后一句，要么是對該段的總結，要么是For example后例證的并列。作為總結性的答案在選項中已經沒有了，只可能是并列關系，因此選F.

5.利用關鍵詞來解題。

對于50題，我們可以完全用關鍵詞來解題。在最后一段第一句中出現了critics這個單詞，由此可見該段主要講批評家對home schooling所持的態(tài)度，在六個選項中只有B答案中出現了critics這個詞，因此只能選B.

6.利用時間關系來解題。
