【题目】按要求完成下列各题
【1】We finished the task yesterday. (改为一般疑问句)
____ you ____ ____ task yesterday?
【2】I meet a girl. The girl enjoys reading. (改为定语从句)
I meet a girl ____ ____ ____.
【3】We got a lot with our hard work. (改为同义句)
We got ____with our hard work.
【4】Our teacher is pleased with our performance. (改为同义句)
Our teacher ____ ____ ____ our performance.
【5】They work behind_the_scenes. (对画线部分提问)
____ ____ they work?
【答案】
【1】 Did finish the
【2】 who enjoys reading
【3】much
【4】 is happy with
【5】 Where do
【解析】
【1】句意：我们昨天完成了任务。
本题要求改为一般疑问句，句中谓语动词finished是实意动词的过去式形式，疑问句应用助动词did构成，还需注意将过去式变为原形。故答案为Did finish the。
【2】句意：我遇见一个女孩。这个女孩喜欢阅读。
本题要求合并句子，根据原句句意可知，第二句话对a girl起到了修饰的作用，故将第二句话变为定语从句，先行词是a girl，指人，故定语从句用who引导；后两个空还是enjoys reading。故答案为who enjoys reading。
【3】句意：我们通过努力工作得到了很多。
根据句子结构可知，该空替换的是原句的a lot，意为“许多”，同义词是much。故答案为much。
【4】句意：我们的老师对我们的表现感到非常满意。
根据句意和句子结构可知，该空考查的是原句is pleased with“对……感到高兴或满意”的同义短语，可以用is happy with来替换。故答案为is happy with。
【5】句意：他们在屏幕后面工作。
原句划线部分behind the scenes表达的是工作的地点，故疑问词应用Where；谓语动词do是实意动词的原形，主语they是复数，故疑问句用助动词do构成。故答案为Where do。
这个题目是句型转换，考查了一般疑问句、特殊疑问句、同义句和定语从句。变一般疑问句时，首先看句中是否有be动词或情态动词，如果有，则直接把它们提到主语前面；如果没有，则应用助动词do, does或did构成一般疑问句，does用于一般现在时，主语为第三人称单数时；did用于一般过去时态中。注意要将原来的三单形式以及过去式都变为原形。如第1小题，句中谓语动词finished是实意动词的过去式形式，疑问句应用助动词did构成，过去式finished变为原形finish。定语从句是修饰名词的句子，所修饰的名词叫先行词，当先行词是人时，用who或that引导，在从句中作主语或宾语，作宾语时还可以用whom；先行词是物时，用which或that引导，在从句中作主语或宾语。如第2小题，先行词是a girl，指人，故定语从句用who引导；后两个空还是enjoys reading。
优翼小帮手同步口算系列答案【题目】 These days, the environment is a huge topic. It seems like we’re always being reminded to recycle, or to ride a bike instead of taking a taxi.
However, it isn’t just rubbish and traffic that can cause harm to the environment.
According to a recent study by the University of California, published by the journal Science Advances, fertilizer (化肥) in farm soils is a major contribution to smog in nearby cities. According to the research, agricultural soils make up of 25 to 41 percent of nitrogen oxide emissions (氮氧化物排放) in California. Nitrogen oxide, or NOx, is a major cause in smog formation.
“Emissions of NOx from agricultural areas are much higher than we used to believe and could be a major source（来源） of NOx statewide,” the researchers wrote in the study.
Just like fertilized farmland, there are many other things that we wouldn’t expect to have a huge influence on the environment. Take clothes for example. Data (数据) published by the World Wildlife Foundation says that every kilogram of cotton takes around 10,000 liters of water to produce.
This means that it takes around 6,000-8,000 liters of water just to create a single pair of jeans, not to mention the carbon produced when they’re made in the factory and then transported to a store.
And even what we choose to eat could be bad for the planet.
In a 2014 study carried out by a professor in New York, US, it was found that beef farming could be causing more harm to the environment than all of the planet’s cars.
So does this mean that we should all stop buying jeans and eating beef? That would certainly help, although it’s not a practical goal.
Instead, a few simple changes could be made. For example, there’s no need to buy new jeans every year when a good pair can last much longer than that.
And when it comes to food, taking the place of the beef in our dishes with chicken or pork every now and then will still mean they taste as delicious.
Indeed, small actions could make a huge difference to our planet.
Unexpected things that 【1】 the environment
What they are | Fertilizer: It plays a 【2】 role in causing the smog in our nearby cities. |

What we can do | It is 【5】 to stop buying jeans and eating beef, but small action could make a huge difference. |
