3. 利用文章中對詞的定義猜測詞義

Example：

Such experiences are not unusual for the amateur conchologists, people who collect shells.

Conchologists的意思可以根據該詞后面的同位解釋"people who collect shells"理解為收集貝殼的人或貝殼收藏家。

Example :

Jack is now a florist, who keeps a shop for selling flowers in our district.

"florist" 的意思就是其后定語從句"who keeps a shop for selling flowers 所描述的"擁有一家專門賣花的商店的人"，即"花店主"

4. 利用文章中對詞的舉例及解釋猜測詞義

Example :

Today young couples who are just starting their households of ten spend lots of their money on appliances ,for instance ,washing machines , refrigerators and color TVs.
通過所舉的例子（washing machines ,refrigerators and color TVs）
可以看出，"appliances" 應是這些名詞的總稱，即"家用電器"。

Example :

Finally the enemy surrendered .They threw down their weapons and walked out of the home with their hands over their heads .

通過后一句對"surrendered"的解釋：扔掉武器（throw down their weapons ）,舉起雙手（with their hands over heads ）可知其意是"投降"

5. 利用構詞法知識（前綴和后綴）猜測詞義

Example :

They overestimate the interviewee's ability and asked him many difficult questions
"estimate"是"估計"的意思，"over－"是前綴，意為"過分，過度，超　過"等，因此"overestimate"就是"高估"的意思。

Example :

We were told that ours was the most spacious room in the hotel .That was why we had to pay so much for it .
"spacious"是由"space(名詞，空間)"＋"＋－ious(形容詞后綴　"變化而來的，因此，可猜測其詞義為"寬敞"。
各種各樣的前、后綴可以構成名詞、形容詞、動詞、副詞等，這些詞綴需要平時不斷地積累和記憶。掌握構詞法知識是擴大詞匯量和猜測生詞詞義的最佳辦法。
