题目内容
I called you, but nobody answered. Where ________ you?
| A.is | B.are | C.was | D.were |
D
解析试题分析:句意:我给你打电话了。但是没有人接。你在哪儿?结合语境可知下文描述的是过去的状态,故谓语动词用过去式。You是第二人称,故用are的过去式were,选D。
考点:时态就主谓一致
点评:英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型,首先要注意句子中的时间状语,如果没有则要通过分析上下文,结合语境来判断句子的时态。英语疑问句中一般具有时态上的对应关系,注意结合这一特点进行区分。be动词往往根据句子的主语而有所不同,其应用原则可以结合如下歌谣来记忆;我用am,你用are;is用在他、她、它。单数名词用is,复数名词全用are。
The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp* sense of smell. The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana. The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’ training, the rats were taken to a minefiel山 They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers* that they smelt out’a mine. Then the mine was cleared. It had taken two ‘deminers a day to clear a 200㎡ . minefield, but with the help of two rats ‘they could finish it in two hours.
The rats and ~he deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.
