14．Only when he went abroad ___ the importance of learning foreign languages．（　　）

A．

he realized

B．

did he realize

C．

he did realize

D．

he had realized

分析只有当他出了国他才意识到学习外语的重要性．

解答答案：B．
在only出现在句首后接时间状语时要注意后面主句要部分倒装，即：将助动词或情态动词放到主语的前面、be动词直接置于主语之前；没有助动词时，要求加适当的助动词（谓语动词过去式时，用did、一般现在时用do），根据 went 可以判断句子使用的是一般过去时，所以这里加did．故选B．

10．Nowadays，the food that you buy comes from many different countries．Have a look in your fridge，cupboard，and fruit bowl and check the origins（来源） of the food．Perhaps there are apples from California，lamb from New Zealand，or potatoes from Egypt？You will probably be surprised how far food travels to get to your plate．This journey，from"field to plate"，is called"food miles"．A food mile is the distance that food travels from the farmer's field to the person who buys the food．Nowadays，food often travels thousands of miles to get to the consumer（消费者）．Why is this，and what are the effects（影响） of these long distances？
Traditionally，farmers sold their food in the local market so the food didn't have to travel very far．The consumers also did not travel very far，because they went to their local market to buy the food．This was a good system for farmers and consumers．However，there were some disadvantages．For example，consumers could only buy food that farmers produced locally．In addition，they could only get food that was in season．Now，because of modern technology，food comes from all over the world．We do not have to wait for spring or summer to buy strawberries or tomatoes．They are available in winter if we want．
Some countries have to import（进口） most of their food．This is because they have difficult climates．The United Arab Emirates（UAE），for example，gets 85% of its food from other countries．Even food made in the UAE often uses imported materials．
What's wrong with"food miles"？Is this not a good way of increasing international trade？I believe these miles are worrying for a number of reasons．First of all，because food travels such long distances．we need more planes，lorries，and ships to move the food．This means we use more oil or petrol，so there is more pollution and more global（全球的） warming．In addition，food that travels a long way is not fresh and usually not very tasty．Tomatoes，for example，are picked early and stored for their long journey．For this reason，they are usually tasteless when they get to the consumer．Local food has a better taste，and it also reduces the amount of global pollution．We need to buy more local food．

A．The origins of the food．
