---- Look! Somebody_______ the sofa.

---- Well, it wasn't me. I didn't do it.

A．is cleaning         B．was cleaning       C．has cleaned        D．cleaned

 

【答案】

C

【解析】

試題分析：句意：看，有人已經(jīng)打掃了沙發(fā)。——哦，不是我。我不會(huì)做的。結(jié)合語(yǔ)境可知上文描述的是現(xiàn)在已經(jīng)完成的動(dòng)作，故用現(xiàn)在完成時(shí)態(tài)。選C。

考點(diǎn)：時(shí)態(tài)

點(diǎn)評(píng)：英語(yǔ)中的時(shí)態(tài)主要是借助于時(shí)間狀語(yǔ)與上下文語(yǔ)境來(lái)進(jìn)行判斷。解答此類(lèi)題型，首先要注意句子中的時(shí)間狀語(yǔ)，如果沒(méi)有則要通過(guò)分析上下文，結(jié)合語(yǔ)境來(lái)判斷句子的時(shí)態(tài)。英語(yǔ)疑問(wèn)句中一般具有時(shí)態(tài)上的對(duì)應(yīng)關(guān)系，注意結(jié)合這一特點(diǎn)進(jìn)行區(qū)分。

Alexis Rocha is a 13-year-old boy from California, US. He weighs 147 pounds (67 kg). But six months ago, he weighed more than 202 pounds (91 kg). How did he lose all that weight in only half a year?
“One day, I was surprised to find that I weighed about 200 pounds,” Rocha says. “I thought I had to do something.”
Rocha is from a boxing (拳擊) family—his father and two older brothers are professional boxers. So he decided to start boxing. He began with simple exercises, like sit-ups and push-ups (俯臥撐). Then Rocha started jogging(慢跑). “No kid likes running,” he says. “I don’t want to do it, either, but I have no choice but to keep on.”
Months later, Rocha joined a boxing club in his city. He is always the first kid at the club to begin exercising, and the last to leave with sweat (汗水) on his face. Every day he boxes for about three hours.
“Rocha works very hard,” says his coach, Hector Lopez. “It’s surprising to see him lose the pounds so quickly. I’ve never seen anything like this in my 20 years of coaching.”
Rocha is very happy with his weight now. There is a family photo in his room from 18 months ago. “Each time I look at the photo, I laugh at myself. I was so big back then,” Rocha says. “I look 100 times thinner and 1,000 times stronger now.”

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.
Some of the light is reflected and some is taken in (吸引) and turned into (變成) heat (熱能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.
【小題1】When something reflects light, we can _____.
A．see its colorB．see its heatC．not see its colorD．see nothing
【小題2】Something looks white because it reflects _____.
