1 . A new report connects eating eggs to an increased risk of heart disease. The results follow several earlier studies that found eating eggs was generally healthy. The study collects data from six other earlier studies. It shows a 6 percent increased risk of heart disease when the number of eggs a person ate each day increased by half an egg.
Norrina Allen, an associate professor at Northwestern University said that, in the United States, eggs are generally one of the top sources of cholesterol(胆固醇)in a person’s daily food. People with higher levels of cholesterol in their food are at increased risk of the development of heart disease later in life. However, Allen added that she would not say that eggs are completely unhealthy. “I’m not saying that people should take them completely out of their food,” she said. “I’m just suggesting that people eat them in a proper amount.”
Some experts believe the new study does not prove that eggs are causing heart disease. “Cholesterol’s role in the development of heart disease has been discussed for more than 30 years,” said Bruemmer, an associate professor of medicine at the University of Pittsburgh Medical Center. “This study does have clear shortcomings, including self-reporting at a single time point,” he added.
Bruemmer said, “Eggs in moderation(适度)are probably acceptable from a nutritional standpoint.” “Moderation,” he added, “is less than one egg a day, including eggs in foods such as bread”.
Holly Andersen, a doctor at the NewYork-Presbyterian/Weill Cornell Medical Center, agrees that the study has “real shortcomings”. One problem Andersen has with the study is that a lot of the egg-eating people in the study also appeared to be eating much meat and processed meat. “If you’re taking a lot of processed meat, it doesn’t matter how many eggs you’re eating,” Andersen said.
Also, Andersen said, “The study can only show there is a relation between eggs eating and heart disease. But it cannot prove eggs are the cause of the disease. It may just be that people eating a lot of eggs are also taking a lot of bacon.”

2 . I want to talk about the economy. Not "the economy" we hear about endlessly in the news each day and in politicians' speeches. I want to talk about the real economy, the one we live in day by day.
Most people aren't particularly interested in "the economy". "Share prices are flying high； interest rates are soaring(猛增的); the Dow Jones Index closed sixty-three points down on 8472.35. " We hear this and subconsciously switch off.
Notice that "the economy" is not the same as the economy, "The economy" is what men in suits play with to make vast personal wealth. The economy is where the rest of us live on a daily basis, earning our living, paying our taxes, and purchasing the necessities of life.
We are supposed to be benefiting from all the advantages of a well-off society. So why do we feel tired and stressed? We have no time for anything other than work, which is ridiculous given the number of labor-saving devices in our lives. Our towns become more and more crowded. We poison our air and seas, and our food is full of chemicals. There's something wrong here. If times were truly good, then you may think we'd all feel optimistic about the future. Yet the majority of us are deeply worried. More than 90 percent of us think we are too concerned about ourselves and not concerned enough about future generations.
The term "economic expansion" suggests something desirable, but expansion simply means spending more money. More spending doesn't mean that life is getting better. We all know it often means the opposite—greed, crime, poverty, pollution. More spending merely feeds our whole economic system, which is based on production and consumption. Unless money keeps circulating, the economy breaks down. If we don't keep consuming, the whole system goes into stalemate(僵局).
How do we break the cycle and make some changes? We need to become far more aware of the results of our actions. We buy clothes that are made in sweat shops by virtual slaves in poor parts of the world. We create mountains of waste. We demand cheap food, mindless of the fact that it totally lacks taste and is produced using chemicals that poison the land.
The consumption culture makes us unaware of the effect of our own behavior. Our main problem is not that we don't know what to do about it. It is gathering the desire to do it.

3 . Mexico and the USA share a common border on the northern side of Mexico. However, despite the close physical proximity(临近), there are a lot of differences between their social conduct.
Americans belong to diverse ethnic (种族) as well as national origins, despite which, all of them have mixed perfectly with the mainstream of American culture. Officially, six different races of people have been recognized by the government of the United States, which include White or European Americans, American Indians and Alaska Natives, Native Hawaiians and other Pacific Islanders, Black or African-Americans, Asians, and the people of two or more races. White Americans form the majority, constituting about 75% of the total population of America.
Mexicans are a group of multi-ethnic people. Mexico shelters people of different races, religions and tribes. When the country achieved independence from the Spanish colonizers (殖民者), the population included people of native pre-Columbian ancestry as well as Europeans, who came there through the process of colonization. The fusion of these two, particularly diverse ethnicities, led to the formation of the special multi-ethnic character of the Mexican people.
Americans tend to give a lot of importance to their profession, sometimes more than their family. Children are brought up in a more independent manner. Parents expect their children to set up their independence households once they start earning. Americans feel that the practical application of knowledge is very important. So, their way of acquiring knowledge is based more on reasoning, analysis, and in-depth specialization of a subject.
However, family comes first for Mexicans. In most Mexican families, men work to earn money, while women take care of the housework. Children are brought up with a lot of parental care and attention. Mexicans love to settle down in one place, and prefer to stay with their families. They consider titles and positions as their status symbols. They believe in education based on repeated learning and so, their academic system emphasizes learning through memorization.
Despite so many differences in their cultures, some sort of integration (结合) binds the Mexicans and the Americans, in a way, promotes their co-existence.
1. Which of the following is true according to Paragraph 2?| A．American Indians and Alaska Natives are the largest ethnic group in the USA. |
| B．There are more Native Hawaiians and other Pacific Islanders than Asians in the USA. |
| C．American Indians have not been recognized by the US government. |
| D．European Americans make up about three fourths of the USA’s population. |
| A．competition | B．mix |
| C．comparison | D．balance |
| A．Truth comes from practice. | B．Blood was thicker than water. |
| C．Rome was not built in a day. | D．Every dog has its day. |
| A．look at money as a status symbol | B．usually receive an all-round education |
| C．enjoy the company of family | D．husband and wife share the housework |
4 . Reducing class size has traditionally been seen as an important way to improve a student's educational experience.
Many public opinion studies have shown that both teachers and parents favor small class size. Teachers who go on strike are often seeking lower classroom numbers among other better working conditions. Many often believe that smaller classes would permit teachers to give more personal attention to their student. This can theoretically lead to improved academic results for student.
But one recent study suggests there is not much research-based evidence to support this idea. The researchers say the idea of smaller class sizes has been studied and debated for many years. However, they noted a lack of clear research to support class size reductions.
The study notes that one of the main problems with reducing class sizes is that it can have very high costs. Increasing class size is one of the most common ways school systems control education spending. Financial limitations make it very difficult for many schools to reduce the number of students in the classroom.
The teachers' goal was to examine the major research studies already completed on the subject. They especially centered on studies that tried to measure whether the smaller class size resulted in greater success for students.
'The researchers conclude that there is some evidence to suggest that reducing class size may lead to some improvement in a student's rending achievement. But they said "the effect is very small." They found just a 53-percent chance that a randomly selected test score from a student from a small class would be higher than the selected score of a student from a lager class. For mathematics achievement, the result was 49 percent. This led the researchers to conclude that there would be little benefit to math students in a smaller class size.
1. Why do some teachers prefer reducing class size?| A．They believe it may help improve students' academic performance. |
| B．It'll greatly better their working conditions. |
| C．They think it will bring much attention to their efforts. |

| A．has nothing to do with students' scores |
| B．has a minor effect in some fields |
| C．has already led to greater academic success |
| D．isn't practical because parents object to it |
| A．The Future of the Class Size Development |
| B．People's Preference for Class Size |

5 . An old man in a faded yellow shirt sat in a windowless room on a raised concrete form. The only source of heat came from somewhere beneath the plastic mattress and the rough blanket the blank-faced police woman had handed him after taking his thumb prints. He heard voices and metallic clang as the cell door swung open.
At the front desk a tired looking policeman handed the old man back his belongings, his worn-out cap and the Seiko watch that had stopped working the day his beloved Evelyn left. The policeman dramatically held the blue plastic bag at an arm's length to the old man who took it and made sure its contents were undamaged: the goat meat, palm oil, leaves and spices. He ignored the confused expression on the officer’s face and signed the document declaring he had been returned the possessions they had taken off him the night before.
No one spoke to him as he walked slowly towards the exit.
''Mr. Easy-nwa? '' He stopped and prayed to the God who now took care of Evelyn to please take him far away from this unhappy place of expressionless faces, clipped accents and people who did not even attempt to pronounce his name right.
''Ezenwa,'' He said and looked at a woman with tangerine lips, her name tag said Jessica Harlow, Social Services. ''A bit far from home'' she said as she drove fast and with confidence the way Evelyn used to. He wondered if she meant the 50 miles from Liverpool or the 50,000 miles from Enugu，a city in Nigeria. He did not bother replying as this woman had plenty to say about the weather, bad drivers, her daughter's school play...
At last she drew up outside the block of flats where he lived.
''Got here in the end''，said she seriously, ''Really Mr. Easy-nwa, if you keep getting lost, we will have to consider moving you into a home''.
''No need, I was not lost, '' he answered. He carefully rolled up the sleeves of the oversize bomber jacket he wore and turned on the tap to wash his hands, relieved the pipes were not frozen.
In a clean pan he placed the chopped pieces of goat meat. The herbs and spices that had taken him three months to track down, the uziza seeds had taken him into the heart of Granby Market in Liverpool, his uchanwu leaves down a shady back alley in Manchester, and yesterday, among other food items, the finest goat meat from a Sierra Leonean Butcher in Birmingham. That had taken some time, so much he missed the last train and when the police found him shivering outside the locked-up station, so cold he couldn't answer loudly enough the pink-faced big copper who yelled in his face, ''What's your name sir? '' spraying his face with spittle (唾沫)as he did so, leaving them with no choice but to search an exhausted, frozen old black man and finding him in possession of mysterious condiments (调味品)including a bag of dried bitter-leaf which could of course be mistaken for anything that resulted in him getting read his rights and charged with ...possession???
He lifted the lid of the bubbling soup, the room was filled with the rich and spicy scent of his culinary (烹饪的)effort. He served two bowls, taking the chipped one and placing the other opposite where Evelyn would have sat. He would tell her about his adventure, it was their anniversary and this was the perfect pepper soup to celebrate.

6 . Like all big cities, Paris has a traffic problem: lots of cars. lots of traffic jams and lots of pollution from exhaust fumes(废气). So the city began a scheme(计划)to improve the situation.
Under the Velib scheme ('Velib' comes from velo liberte, or 'bicycle freedom') people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour-on the bike is free, but if you don't return it after 30 minutes, you have to pay. But it's only € 1 a day or € 29 a year! The bicycles are heavy (25kg), and they are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!
Paris is not the first city to have a scheme like this. But not everybody thinks it's a great idea. One Parisian said. “These bicycles are only for short journeys. If people want to travel across the city, they won't use a bicycle-they'll still use their cars.”
A city spokesman said, “The bicycle scheme won't solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren't any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems in our environment will get worse. The bikes might help people to lead a healthier life, too. “

7 . “Data is the new oil.” Like the sticky black thing, all those Is and 0s are of little use until they are processed into something more valuable. That something is you.
Five of the world’s ten most valuable companies are built on a foundation of tying data to human beings. Google and Facebook want to find out as much as possible about their users’ interests, activities, friends and family. Amazon has a detailed history of consumer behavior. Tencent and Alibaba are the digital wallets for hundreds of millions of Chinese; both know enough about consumers to provide widely used credit scores. Those with a good Zhima credit score, provided by Alibaba, enjoy discounts. Those without receive few offers. In other words, data are used to decide what sort of access people have to services.
That data are valuable is increasingly well-understood by individuals, too, especially because personal information is so often leaked（泄露）or stolen. The list of companies that have suffered some sort of data leak in 2018 alone reads like a roll call of household names: Facebook, Google, British Airways and so on. Such events have caused a switch in the public understanding of data collection. People have started to take notice of all the data they are giving away.
Yet few people have changed their online behavior or exercised what few digital rights they possess. Partly this is because managing your own data is time-consuming and complex. But it is more because of a misunderstanding of what is at risk. “Data” is an abstract concept. Far more solid is the idea of identity. It is only when “data” is understood to mean “people” that individuals will demand responsibility from those who seek to know them.
The fossils of past actions fuel future economic and social outcomes. Privacy rules and data-protection regulations are extremely important in protecting the rights of individuals. But the first step towards ensuring the fairness of the new information age is to understand that it is not data that are valuable. It is you.

8 . Before he sailed round the world alone, Francis Chichester had already surprised his friends several times. He had tried to fly round the world but failed. That was in 1931.
The years passed. He gave up flying and began sailing. He enjoyed it greatly. Chichester was already 58 years old when he won the first solo transatlantic sailing race. His old dream of going round the world came back, but this time he would sail.His friends and doctors did not think he could do it, as he had lung cancer. But Chichester was determined to carry out his plan. In August 1966, at the age of nearly 65, an age when many men retire, he began the greatest voyage of his life.
Chichester covered 14100 miles before stopping in Sydney, Australia. This was more than twice the distance anyone had previously sailed alone. He arrived in Australia on 12 December, just 107 days out from England. He received a warm welcome from the Australians and from his family who had flown there to meet him. On shore, Chichester could not walk without help. Everybody said the same thing: he had done enough; he must not go any further. But he did not listen.
After resting in Sydney for a few weeks, Chichester set off once more in spite of his friends' attempts to dissuade him. The second half of his voyage was by far the more dangerous part, during which he sailed round the treacherous Cape Horn.After succeeding in sailing round Cape Horn, Chichester sent the following radio message to London: "I feel as if I had wakened from a nightmare. Wild horses could not drag me down to Cape Horn and that sinister Southern Ocean again."
Just before 9 o'clock on Sunday evening 28 May 1967, he arrived back in England, where a quarter of a million people were waiting to welcome him.Queen Elizabeth II knighted(授以爵位) him with the very sword that Queen Elizabeth I had used almost 400 years earlier to knight Sir Francis Drake after he had sailed round the world for the first time.The whole voyage from England and back had covered 28,500 miles. It had taken him nine months, of which the sailing time was 226 days. He had done what he wanted to accomplish.
