Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts hardly lose their pumping power with age.
“We have found that the power of the male heart falls by 20---25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK. “Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender (性别)difference might just explain why women live longer than men,” said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.The underlined word “longevity” in the second paragraph probably refers to _________.
| A．health | B．long life | C．ageing | D．effect |
The text mainly talks about ________.
| A．men’s heart cells | B．women’s ageing process |

| B．women can replace the cells that enable the heart to beat |
| C．the female heart loses few of the cells with age |

| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |

English is an important global language, but that doesn’t mean it’s easy to learn. Many experts have tried to make English easier for students to learn―but they weren’t always successful.
In 1930, Professor CK Ogden of Cambridge University invented Basic English. It had only 850 words (and just eighteen verbs) and Ogden said most people could learn it in just thirty hours. The problem was that people who learned Basic English could write and say simple messages, but they couldn’t understand the answers in “real” English! It was also impossible to explain a word if it wasn’t in the Basic English word list. For example, if you wanted a watermelon, you asked for “a large green fruit with the form of an egg, which has a sweet red inside and a good taste”!
RE Zachrisson, a university professor in Sweden, decided that the biggest problem for learners of English was spelling, so he invented a language called Anglic. Anglic was similar to English, but with much simpler spelling. “Father” became “faadher”, “new” became “nue’ and “years” became “yeerz”. Unfortunately for some students of English, Anglic never became popular.
Even easier is the language which ships’ captains use: it’s called “Seaspeak”. Seaspeak uses a few simple phrases for every possible situation. In Seaspeak, for example, you don’t say, “I’m sorry what did you say?” or “I didn’t understand, can you repeat that?” It’s just “Say again.” No more grammar!
In the age of international communication through the Internet who knows? ... a new form of English might appear. A large number of the world’s e-mails are in English and include examples of “NetLingo” like OIC (Oh, I see) and TTYL (Talk to you later). In another fifty years, English might not exist ... we will probably all speak fluent Internetish!The best title for the passage would be ______.
| A．Seaspeak | B．Basic English |
| C．Internetish | D．Easy English |
It will take a person about ______ weeks to learn Basic English if he spends two hours
learning it every day.
| A．six | B．four | C．two | D．three |
According to Professor Zachrisson, what was the biggest problem for learners of English?
| A．Grammar. | B．Vocabulary. |
| C．Speaking. | D．Spelling. |
Which of the following is likely to be Anglic?
| A．IOU | B．A graet batl. |
| C．Long time no see. | D．Two five, no lights. |
What might happen to English in another fifty years?
| A．It might be replaced by Internetish. |
| B．It might become a global language. |
| C．It might take the place of all other languages. |
| D．It might become more and more difficult. |
Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important, of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.What does the underlined phrase "over-consumption" refer to?
| A．Using too much packaging. |
| B．Recycling too many wastes. |
| C．Having more material than is needed. |
| D．Making more products than necessary. |
The author uses figures in Paragraph 2 to show_______.
| A．the tendency of cutting household waste |
| B．the increase of packaging recycling |
| C．the fact of packaging overuse |
| D．the rapid growth of supermarkets |
According to the text, recycling_________.
| A．means burning packaging for energy |
| B．helps control the greenhouse effect |
| C．is the solution to gas shortage |
| D．leads to a waste of land |
What can be inferred from Paragraph 4?
| A．Unpackaged products are of bad quality. |
| B．Supermarkets care more about packaging. |
| C．Other products are better packaged than food. |
| D．It is improper to judge quality by packaging. |
What can we learn from the last paragraph?
| A．Needless material is mostly recycled. |
| B．Fighting wastefulness is difficult. |
| C．People like collecting recyclable wastes. |
| D．The author is proud of their consumer culture. |
The day when the jobs were handed out was one of the most exciting moments for all the children in the class. It took place during the first week of the term. Every kid was given a job for which they would be responsible for the rest of that school year.
Some jobs were more interesting than others, and the children were eager to be given one of the best ones. When giving them out, the teacher took into account which pupils had been most responsible during the previous year. During the previous year Rita had carried out the teacher’s instructions perfectly. All the children knew Rita would be given the best job.
But there was a big surprise. Each child received a normal job. But Rita’s job was very different. She was given a little box containing some sand and one ant. Though the teacher insisted that this ant was very special, Rita felt disappointed. Most of her classmates felt sorry for her. Even her father became very angry with the teacher and he encouraged Rita to pay no attention to this insignificant pet. However, Rita preferred to show the teacher her error by doing something special with that job of little interest.
Rita started investigating all about her little ant and gave the ant the best food, and it grew quite a bit bigger.
One day, a man, who looked very important, came into their classroom and declared, “Your class has been chosen to accompany me, this summer, on a journey to the tropical rainforest, where we will investigate all kinds of insects. Among all the schools of this region, your class has best cared for the little ant.”
That day the school was filled with joy and celebration. Everyone thanked Rita for having been so patient and responsible.
