1．____of the land in that district____ covered with trees and grass．
A．Twofifths；isB．Twofifth；areC．Twofifth；isD．Twofifths；are

分析 這個地區(qū)2/5的地被樹和草所覆蓋．

解答 正確答案：A．英文中分子用基數(shù)詞，分母用序數(shù)詞，且當分子大于1，分母應(yīng)用復(fù)數(shù)形式，則2/5的表達是two fifths；當分數(shù)作主語時，謂語的單復(fù)數(shù)由分數(shù)后的名詞單復(fù)數(shù)決定，land是單數(shù)，則應(yīng)填寫is，故選擇A．be covered with表示被…所覆蓋．

點評 本題考查分數(shù)及主謂一致，掌握分數(shù)的英文表達，再根據(jù)題干進行選擇．

12．Squirrels （松鼠） are getting ready for winter．They are looking for nuts and seeds，digging holes in the ground or finding holes in trees．That's where they store the food they will need during the coming months，when the weather is cold and sometimes snowy．Squirrels spend a lot of time in trees，which are like restaurants for them．Among their favorite things to eat are nuts and other parts of trees，like tender buds （花苞）．Squirrels may also eat corn，insects and other animals．And，as anyone who has a bird knows，squirrels love bird food!
Squirrels stay active all winter，so they need plenty of food to help keep up their energy．Squirrels tend to buryfood underground，piece by piece．Some squirrels may gather food into piles that they put at the base of trees or bury underground．When they need the food，squirrels use their memories and sense of smell to help them find what they buried．Sometimes，you'll even see them digging through the snow．

16．Learning can take place in a classroom，in a meeting room，or even on a ship．Life experiences offer the students some of the best education on the earth．Of those life experiences，travel offers the best returns（回報）．
For international travelers，the lessons are the greatest．Taking that first step to cross the ocean by plane or boat is a risk．It teaches people to see more and people can go beyond one land，one country，and one set way of thinking and doing things．
International travel opens up the mind with different cultures．Travelers see how different people do things in different lands．While this experience is exciting for adults，children get the greatest insights（洞察力） during the international exploration．It will help to form their understanding from a very young age．It wll help them understand that differences among people and cultures can be quite exciting and wonderful in its own way．Fashion，art，science，transportation，religion（宗教），geography，geology（地質(zhì)學） and social studies are all areas of learning outside of the books when traveling in foreign countries．There is no other way that can teach so much information in such a shorttime．
You can learn more from travel than from any other educational experience．If you take no notice of everything you see，then surely you will learn nothing at all．But，if you are curious enough to look for new experiences through travel，you can learn more than from any course in any university on the earth!
Topic：Learning while traveling
TravelTravel，one of life experiences （1）provide the students with some of the best education．
