Recently, many e-commerce platforms, including Didi Taxi, Ctrip, Fliggy, JD ad Taobao, have been uncovered that they are cheating their frequent customers. Their ways are pretty clever. When there are new users or conservative old users, they will give a quite appealing price to attract them into registering and buying goods. However, their big data is not that friendly to the stable users and frequent visitors. The system always offers them higher price for the same products or service. How does this happen? According to the data analysis, the system knows clearly that although they feel the price is high, they will finally pay the bill. By collecting and analyzing users’ profiles, buying habits and other information, big data recommends the same products to different users with different prices.
Companies also try other ways to make money, making online consumption far more worrying. For example, video websites always offer 120 seconds’ advertisements, which drives people crazy. And even if you pay for the membership to get rid of the ads, you have to “enjoy” 15-second “private” ads. By broadcasting them, companies make huge profits — second to the membership fees. Also, owning 100Mbps network, you still put up with the slow speed when you are downloading a song. You have no choice but to become a VIP when you seek high quality services. Users seem to be lambs(羊羔) among wolves. Even though they say, “Since you have money, I’ll charge you more”, we can’t do anything about it.
It pains us that we haven’t figured out a way to deal with the problem. The only thing we can do is replacing our iPhones with Android phones if we want to buy a membership card, and applying for new accounts if we want cheaper hotels. Not finding a way to fight back, we can’t do anything but accept them passively.

The entire family was here recently –14 in all, including six kids under the age of 5. We had a joint birthday party for two of the grandkids.
The day after everyone cleared out I noticed that the drain stopper（排水塞）was missing from downstairs bathroom sink.
The last thing you want to do is accuse your own fresh and blood of stripping hardware from your bathroom, but a drain stopper doesn’t just wash itself down the drain.
So I sent out a carefully-worded e-mail saying what a wonderful time we had and asking if anyone had accidently tucked a drain stopper in a purse, pocket or suitcase. I even attached a picture of a drain stopper in case there was any doubt as to what the missing part looked like.
Our son responded that he thought his 10-month-old might have eaten it. He said he’d let us know if they found it in the next day of two.
Our youngest daughter responded that she thought she saw it in her husband’s lunchbox that morning, but she could be wrong.
Our oldest daughter replied that she had suspected her sister’s husband all along. He replied that he had been framed.
Our oldest daughter then checked the guilt of one of her twins with following exchange:
Mommy: “Do you know where Grandma’s drain stopper is?”
Three-year-old: “Yeah, let me show you.” (Heads to the bathroom.)
Mommy: “No, not ours, where is Grandma’s? Did you take it?”
Three-year-old: “I think she took it.” (She points at her 18-month-old baby sister). “She’s a naughty kid.”
Naturally, the 18-month-old defended herself by saying: “Bububbubnananabublalala!”
The next day, an email arrived from our daughter-in-law. “Guess what I found in my laundry this morning? I thought the dryer was louder last night.”
Our “perp” was short. He has a known history of building and disassembling, is mechanically inclined, determined and just turned 3.
It’s always good to know a child’s interests and talents. We have a valve（阀门）that occasionally drips under the kitchen sink. I may have him take a look at it the next time he’s here. But I’ll pat him down before he leaves.

Tiny water plants called phytoplankton (浮游植物) serve as food for many sea creatures, including whales, shrimp, jellyfish and snails.
Phytoplankton do well in cold water. But if water temperatures rise by only two degrees Celsius, the phytoplankton struggle. That is what happened in the last three or four years in the northern part of the Pacific Ocean. Researchers say an unusual area of warm water spread throughout the Northern Pacific. Scientists called the warm water ''the blob'', as if it were a character in an old science fiction movie. At its largest, the blob stretched 1,600 square kilometers and reached depths of 91 meters. This large mass of warm water had a damaging effect on the ocean food chain. Many fish that depend on phytoplankton swam away from the area. As a result, sea birds and sea lions that eat those fish starved.
Scientists from the National Oceanic and Atmospheric Administration and the University of Washington have found that the warm ocean ''blob'' caused a harmful algae bloom. That fast growth in algae hurt fishing grounds along the U.S. West Coast and Canada's British Columbia. The researchers recently published their study in the journal Geophysical Research Letters. They looked at the algae, called P. australis. They found that the algae can grow much faster than normal if it is exposed to warm water. The higher levels of algae also produced more of a poisonous chemical that can cause problems for everything from shellfish to dolphins to sea lions. It also causes problems for humans if too much of the chemical builds up in their blood.
Researchers say algae blooms like this one will continue as ocean waters warm. The algae will hurt sea animals, birds, and fish. It may damage food resources for humans all over the world, the scientists say.
1.The root cause of the starvation of sea birds or sea lions is_____.
A.the depths of the vase sea
B.the large mass of warm water
C.the large amount of polluted sea water
D.the increasingly reduced phytoplankton in the sea
2.From the text, we can know that P. australis is the name of a(n) _____.
A.phytoplankton B.fish
C.algae D.bird
3.The following statements are true EXCEPT_____.
A.Generally, the algae grow much faster than normal if exposed to cool water.
B.The phytoplankton is very sensitive to the rise of water temperature.
C.More algae can bring about a poisonous chemical which endangers sea creatures.
D.Algae blooms will affect not only the existence of sea creatures but also that of humans the world over.
4.The text is most probably taken from_____.
A.a research paper B.a geography textbook
C.a class presentation D.a newspaper report

The English, as a race, are very different in many ways from all other nationalities, including their closest neighbors, the French, the Belgians and the Dutch. It is claimed that living on an island separated from the rest of Europe has much to do with it. Whatever the reasons are, it may be fairly stated that the Englishman has developed many attitudes and habits which distinguish him from other nationalities.
Broadly speaking, the Englishman is a quiet, shy, reserved person who is fully relaxed only among people he knows well. In the presence of strangers or foreigners he often seems restrained, even embarrassed. You have only to witness a city train any morning or evening to see the truth of this. Serious-looking businessmen and women sit reading their newspapers or having a light sleep in a corner, and no one speaks. In fact, to do so would seem most unusual. An Englishman, pretending to be giving advice to overseas visitors, once suggested, “On entering a railway carriage, shake hands with all the passengers.” Needless to say, he was not being serious. There is an unwritten but clearly understood code of behavior which, if broken, makes the person immediately suspected.
In many parts of the world it is quite normal to show openly extremes of enthusiasm, emotion, excitement, etc, often accompanied by appropriate gesture. The Englishman is somewhat different. Of course, an Englishman feels no less deeply than anyone of a different nationality, but he tends to display his feelings far less. This is reflected in his use of language. Imagine a man commenting on the great beauty of a young girl. A more emotional man might describe her state “Oh, she is a goddess”, whereas an Englishman might just say “Oh, she’s all right.” An Englishman who has seen a highly successful and enjoyable film recommends it to a friend by commenting, “It’s not bad you know”, or on seeing some very unusual scenery he might convey (表达) his pleasure by saying, “Nice, yes, very nice.” The overseas visitor must not be disappointed by this apparent lack of interest and involvement. Instead, he must realize that “all right,” “not bad,” and “nice,” very often have the sense of “first-class,” “excellent,” “beautiful”. This unique style of language use is particularly common in England, and is known as restrained statement.
1.According to the passage, the English are different from other nationalities in _______.
A. habits B. attitudes C. character D. all of the above
2.The underlined word “restrained” in the second paragraph probably means “_______”.
A. calm and controlled B. polite and friendly
C. nervous and quiet D. silent and kind
3.In Britain, if you don’t want other people to think you are strange, you’d better _______.
A. talk with others as much as possible
B. behave just like the English do
C. say nothing about yourself
D. shake hands with everyone you meet
4.If an Englishman says “all right”, it may mean “_______”.
A. not bad B. correct C. quite right D. wonderful
5.From the passage, we can infer that an Englishman _______.
A. doesn’t like to show his feelings so much
B. has less emotion than people of other nationalities
C. finds it easy to express his emotion
D. likes to have a joke with strangers

Popular breakfast foods in the United States, as in many other countries around the world, include coffee, milk , juice, eggs, and bread. Some other breakfast items served in the United States are thought by many to be traditionally American. However, they actually come from other cultures.
A very popular breakfast food in America is the pancake--- a thin , flat cake made out of flour and often served with maple syrup. The idea of the pancake is very old. In fact, pancakes were made long ago in ancient China.
Bagels, a round thick bread with a hole in the middle , are also popular for breakfast in America. Polish people in the late 1600s came up with the idea for the first bagels and this new kind of bread soon took off across Eastern Europe.
In the late 1800s, thousands of Jews from Eastern Europe travelled to the United States and brought the recipe for bagels with them. Today, New York bagels are said to be the best in the world. Many people have them with cream for breakfast on the go.
Doughnuts (usually spelled “donut” in the United States) came from France. They were served to American soldiers in France in the World War Ⅰ.
