____ they ____ a cow yesterday?

A．Did; milked        B．Did; milk          C．Do; milked         D．Do; milk

 

【答案】

B

【解析】

試題分析：句意：昨天他們給奶牛擠奶了嗎？結(jié)合語(yǔ)境可知本句描述的是過(guò)去的動(dòng)作，故用一般過(guò)去時(shí)態(tài)，一般過(guò)去時(shí)態(tài)疑問(wèn)句中一般用助動(dòng)詞體現(xiàn)時(shí)態(tài)，行為動(dòng)詞用原形，故選B。

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。

When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows—cow manure (糞肥), to be specific.
Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That’s really a big amount.
When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.
Here’s how it works: A big machine moves back and forth cleaning the barn floor. “The cows aren’t bothered,” says Marie Audet. “They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”
The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化糞池) because what happens there is just like what happens inside a cow: Bacteria(細(xì)菌) get to work and continue to digest the manure.
Methane gas (甲烷、沼氣)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That’s an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (發(fā)電機(jī)).
At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can’t use themselves.
【小題1】We learn from the text that the Audet family is using cow wastes to ______.
A．make electricity B．produce fertilizerC．build their farm D．feed the cows
【小題2】How are the cow wastes collected into the digester at Blue Farm?
A．Marie Audet does the workB．The job is done by machine
C．The cows lift the cow wastesD．Bacteria get to work on them
【小題3】 According to the passage, which of the following is changed into electricity?
A．The power of moving water. B．The heat of burning coal.
C．The power of sunlight.D．The heat of the methane gas
【小題4】The new way of using cow wastes at Blue Farm might be best described as ______.
A．reducingB．savingC．recyclingD．changing
【小題5】 What is the main purpose for writing the passage?
A．To introduce a new way of making electricityB．To explain how a new energy works better
C．To show a new rebuilding plan for a big farmD．To explain the reasons for green house effect
