【题目】 Drinking milk every day is good for your health. However, if one day someone gives you a cup of cow-free milk, will you still want to have a drink?
Recently, an American company named Perfect Day surprised the world with its synthetic (合成的) milk. The milk looks and tastes almost like cow milk and has all the same nutrients (营养素).
The creators of Perfect Day are two young scientists, Ryan Pandya and Perumal Gandhi. Working in different cities, they didn’t know each other at first. But they shared the same crazy idea about making milk without the help from cows. They thought it would make the world a kinder, greener place. After they met, they started working on a way of making their dream a reality.
The secret to making cow-free milk? Yeast (酵母), 3D printing technology and old fermentation processes (发酵方法). They have developed a process quite like making beer. The two scientists also say their milk has longer shelf life than the real milk. What’s more, it’s delicious, safe and Earth-friendly. “We want people to enjoy our milk, while leaving a kinder footprint on the planet,” say the two young men.
However, they also know it will be a long way before people accept their synthetic milk.
Before people accept the synthetic milk, maybe we should do something to reduce waste. A store in Scotland is doing such a thing. It sells milk in a vending machine (自动售货机). The vending machine allows people to refill their glass bottles with fresh milk. “The milk vending machine lets us work with a local farm to get really tasty milk for our customers without wasting plastic containers (集装箱),” one worker from the store said. It helps to save the store about one hundred plastic containers a day.

【2】词义猜测题。根据原文“The vending machine allows people to refill their glass bottles with fresh milk.”自动售货机允许人们用鲜牛奶把玻璃瓶再次装满。分析整段内容,讲的是如何节省包装材料,那么重复使用是最好的办法,所以此处意为“再装满”。故选B。
【3】推理判断题。根据第三段“They thought it would make the world a kinder, greener place.”可知,设计者的初衷是为了使得这个世界更宽容、绿色。故选A。
【4】主旨大意题。根据第三段“They thought it would make the world a kinder, greener place.”可知,设计者的初衷是为了使得这个世界更绿色。故选D。
【题目】 Big data (数据) is a lot of sets of information that are put together so they can be used by a computer program. The computer program looks for different kinds of answers or patterns in the data. Big data can have different kinds of information from many sources, such as information that comes from schools, social media sites, companies and governments.
Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra help in class. The teacher can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream.
Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick. Big data can also be used for bad reasons can be used to predict which kinds of people probably break the law or hurt others, even if they have not done anything wrong
How can big data be used for good and bad thing? It is because the computer programs which are used to look at big data and understand it are written by people. People think a certain way and build a model of the ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people.
