A new commodity brings about a highly profitable, fast-growing industry,urging antitrust(反壟斷)regulators to step in to check those who control its flow. A century ago, the resource in question was oil. Now similar concerns ares being raised by the giants(巨頭)that deal in data, the oil of the digital age. The most valuable firms are Google, Amazon, Facebook and Microsoft. All look unstoppable.
Such situations have led to calls for the tech giants to be broken up. But size alone is not a crime. The giants’ success has benefited consumers. Few want to live without search engines or a quick delivery. Far from charging consumers high prices, many of these services are free (users pay, in effect, by handing over yet more data). And the appearance of new-born giants suggests that newcomers can make waves, too.
But there is cause for concern. The internet has made data abundant, all-present and far more valuable, changing the nature of data and competition. Google initially used the data collected from users to target advertising better. But recently it has discovered that data can be turned into new services: translation and visual recognition, to be sold to other companies. Internet companies’ control of data gives them enormous power. So they have a “God’s eye view” of activities in their own markets and beyond.
This nature of data makes the antitrust measures of the past less useful. Breaking up firms like Google into five small ones would not stop remaking themselves: in time, one of them would become great again. A rethink is required—and as a new approach starts to become apparent, two ideas stand out.
The first is that antitrust authorities need to move form the industrial age into the 21st century. When considering a merger(兼并), for example, they have traditionally used size to determine when to step in. They now need to take into account the extent of firms'data assets(資產(chǎn)) when assessing the impact of deals. The purchase price could also be a signal that an established company is buying a new-born threat. When this takes place, especially when a new-born company has no revenue to speak of, the regulators should raise red flags.
The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them. Companies could be forced to consumers what information they hold and how many money they make form it. Govemments could order the sharing of certain kinds of data, with users' consent.
Restarting antitrust for the information age will not be easy But if govemments don't wants a data oconomy by a few giants, they must act soon.
1.Why is there a call to break up giants?
A. They have controlled the data market
B. They collect enormous private data
C. They no longer provide free services
D. They dismissed some new-born giants
2.What does the technological innovation in Paragraph 3 indicate?
A. Data giants’ technology is very expensive
B. Google’s idea is popular among data firms
C. Data can strengthen giants’ controlling position
D. Data can be turned into new services or products
3.By paying attention to firms’ data assets, antitrust regulators could .
A. kill a new threat B. avoid the size trap
C. favour bigger firms D. charge higher prices
4.What is the purpose of loosening the giants’ control of data?
A. Big companies could relieve data security pressure.
B. Governments could relieve their financial pressure.
C. Consumers could better protect their privacy.
D. Small companies could get more opportunities.

Though the political field is still ruled by men, we can still see another splendid scene — those women with high heels and makeup are playing an active role on the political stage.
Theresa May — the Iron Lady who cleans up the mess
She is the second female Prime Minister and Conservative Party leader after Margaret Thatcher. The mess left by men is finally for women to clean up. After the worldwide–shocking “Brexit”, Cameron has successfully thrown Theresa into trouble. A remain campaigner as she was, Theresa insists that “Brexit means Brexit”. Since taking office, she has already shown her calmness, humbleness, efficiency and powerful leadership.
Merkel — the unquestioned “Big Sister”
From a PhD in physics to a role on the political stage, she is Merkel, the first female chancellor(總理)in German history. Facing the European migrant crisis, she advocated the policy of “Open the Door” and put forward the slogan “We are able to manage it”. However, the coming of refugees not only caused serious social security problems but also brought terrorism and political tsunami.
Hillary — a woman’s presidential dream
Born in a wealthy business family and graduating from Law School of Yale University, Hillary struggled for thirty years on the US political stage and was once the First Lady, Federal Senator and Secretary of State. She is an outstanding but controversial woman in this day and age, since she is rich in not only political experience but also scandals. Hillary, early 70 years old now, ran for the US president twice, only ending up with a broken dream.
Park Geun-hye — a woman who married the country
In December, 2012, the 60-year-old Park Geun-hye was elected the first female president of South Korea. She once pledged: “I don’t have parents, nor do I have a husband and children, and the country is the only one I wish to serve.” Yet the “confidante(紅顏知己)scandal” was undoubtedly a political earthquake for her, ending her presidency and forcing her out of office in March, 2017.
1.What does Theresa May mean by saying Brexit means Brexit?
A. She will carry on Brexit. B. She will postpone Brexit.
C. She will oppose Brexit. D. She will think twice about Brexit.
2.Who ran for presidency twice but in vain?
A. Merkel B. Theresa May
C. Hillary D. Park Geun-hye
3.What can we infer about the four women?
A. Theresa May is better than the former Prime Minister.
B. Merkel is doubtful about her policy towards the refugees.
C. Hillary is the most successful First Lady.
D. Park Geun-hye was in office for not more than five years.

The most exciting storms are the ones with flashes of lightning.Unfortunately,those are scarce,unless you are near the Catatumbo River in Northwestern Venezuela.Here,nature's grandest sound and light show is often seen, because it happens about 160 nights a year.And it lasts for as long as 10 hours at a time.And unlike other lightning storms that cause just one or two flashes,this one is with as many as 280 per hour.It is the highest in the world. Besides,each one of them is so powerful that each can power every light bulb in South America.Not surprisingly,they can be seen for almost 250 miles.Fishermen and sailors often use them to guide them across the waters during dark nights.
What's even more surprising is that the lightning has been happening above the same spot where the Catatumbo River meets Lake Maracaibo for thousands of years.The best part is that the show is different every night.That's because the color of the lightning changes,depending on the amount of water in the atmosphere.On dry nights,the lightning appears white.When the air is not dry,it helps split up the bright light into red,orange and even purple.
Strangely enough,though this has been going on for centuries,scientists have still not been able to figure out the cause of this phenomenon.Some say that the storms are the result of the interaction of the area's unusual topography(地貌),wind and heat.Others,however,believe that the storms are caused by a kind of gas in the area.The locals simply think that it is the "spirit of Catatumbo" that lights up the night sky.
1.According to Paragraph 1,if we say something is scarce,we probably mean .
A. it is far away B. it is very terrible
C. it can be hardly seen D. it can be very dangerous
2.We know that in Northwestern Venezuela, .
A. people daren't go out at night
B. it rains heavily almost every day
C. lightning is used to power light bulbs
D. storms with flashes of lightning are common
3.What has the greatest influence on the colors of the lightning?
A. The spot of the lightning
B. The air of the lightning spot
C. The color of the environment
D. The level of water in the Catatumbo River
4.From the last paragraph,we learn that .
A. scientists will no longer study the lightning storms there
B. locals know about the lightning storms better than scientists
C. heat in Northwestern Venezuela is different from any other place
D. the reason why such lightning storms happen there is still unknown

D
A buld-it-yourself solar still(蒸餾器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5’ 5’ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container— perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.
To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.
Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圓錐體) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.
The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸發(fā)) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink.
1.What do we know about the solar still equipment from the first paragraph?
A.It’s delicate. B.It’s expensive.
C.It’s complex. D.It’s portable
2.What does the underlined phrase “the water catcher” in paragraph 2 refer to?
A.The tube B.The still
C.The hole D.The cup
3.What’s the last step of constructing a working solar still?
A.Dig a hole of a certain size B.Put the cup in place
C.Weight the sheet’s center down D.Cover the hole with the plastic sheet
4.When a solar still works, drops of water come into the cup form .
A.the plastic tube B.outside the hole
C.the open air D.beneath the sheet
