Plastic is everywhere because plastic is an extremely useful material．It is cheap, strong and lightweight．What’s more, it can take on nearly any form or shape, from soft and stretchy （有弹性的） to hard and glasslike.
Plastic, however, is far from perfect．It may even be bad for us．Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder （注意缺陷障碍）.
Two types of chemicals in particular have raised special concern lately．They are called phthalates （邻苯二甲酸盐） and Bisphenol-A （二酚基丙烷）, BPA for short． Not all plastic products contain them．But the ones that do are surrounded by controversy （争议）．That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing．What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture．Plasticizers （塑化剂） are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways．Phthalates add softness to things like shampoo bottles, raincoats and rubber．They are also used in perfumes and makeup．BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles．BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep （渗透） out of the plastic．Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic．Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three．California and Washington have done the same．And a number of other states are considering similar rules．As for BPA, Canada became the first country to ban the chemical from baby bottles．A dozen states are considering it.

A．Its characters and effects．

B．Its wide use and bad points.

C．Its importance and chemicals．

D．Its popularity and advantages.

Which of the following products contains BPA?

A．A soft plastic cup．	B．A pencil eraser.

Marjorie Baer used to joke about her retirement plans．She wasn't married and had no kids, but she didn't intend to be alone—she and all her single friends would move into a fictional home she called Casa de Biddies．Instead, Baer developed terminal brain cancer when she was 52．But just as she'd hoped, her friends and family provided her with love and care to the end．
Ballance was only the first of Baer's friends who became her unofficial caregivers．With her brother Phil Baer from Los Angeles, they worked out a system to watch over their friend and allow her to keep some of the privacy and independence she cherished.
Baer's good friend Ruth Henrich took Baer to doctors' appointments and helped her deal with all the aspects of life —answering machines, TV controls, and even phone numbers．After Henrich sent out an e-mail request, a group of volunteers signed up to ferry Baer back and forth to radiation therapy（放疗）．Others in Baer's circle offered up particular talents: A nurse friend helped Baer figure out how to get what she was due from Social Security and her disability insurance; a lawyer pal helped Baer with her will; a partner who was an accountant took over her bills when she could no longer manage them．"There was this odd sense that the right person always showed up," says Ballance．Their arrangement worked remarkably well．
Unmarried women are one of the fastest-growing groups in America; experts are concerned about how care-giving will be managed for them as they age．If the experience of Baer's friends is a guide, the Internet will play a role．It's already making it possible to create communities of caregivers who may have only one thing in common: the person who needs their help．On personal "care pages" set up through services such as Lotsa Helping Hands, friends and family members can post a list of tasks that need to be done, volunteer to do them, and keep updated on the person's condition．As Baer's cancer progressed, for example, her friends set up a page on Yahoo! where people could sign up to deliver meals or do errands（差事）.
Catherine Fox, one of the friends who were present when Baer died, was deeply affected．"It was so comforting to know that if you're willing to ask for help, the generosity of family and friends can be phenomenal（显著的）．It makes me feel secure and hopeful to know that help is there when you need it．"
The most appropriate title of this passage should be ______．

A．On her own, but not alone

B．A friend in need is a friend indeed

C．A new practice of American government

D．A phenomenal advantage of the Internet

Who helped Marjorie Baer get her disability insurance?

A．Ruth Henrich.	B．Her brother.
C．A nurse friend.	D．Ballance.

A．play a role in American future pension system

B．provide online medical care for aged unmarried women

C．help manage care-giving for unmarried women as they age

D．help those aged unmarried women to kill their spare time

The writer tells us the story of Marjorie Baer for the purpose of ______．
A．reminding us to be kind and make as many friends as we can
B．informing that there will be a new trend of care-giving for the single elderly

These days, it seems that almost all of us are too serious．My older daughter often says to me, “Daddy, you’ve got that serious look again．” Even those of us who are committed to non-seriousness are probably too serious．People are frustrated and anxious about almost everything -- being five minutes late, witnessing someone look at us wrong or say the wrong thing, paying bills, waiting in line, overcooking a meal, making an honest mistake -- you name it, and we all lose perspective（理性判断） over it．
The root of being anxious is our unwillingness to accept life as being different, in any way, from our expectation．Very simply, we want things to be a certain way but they’re not a certain way．Life is simply as it is．Perhaps Benjamin Franklin said it best: “Our limited perspective, our hopes and fears become our measure of life, and when circumstances don’t fit our ideas, they become our difficulties．” We spend our lives wanting things, people, and events to be just as we want them to be -- and when they’re not, we fight and we suffer．
The first step in recovering from over-seriousness is to admit that you have a problem．You have to want to change, to become more easygoing．You have to see that your own anxiety is largely of your own creation -- it’s made up of the way you have set up your life and the way you react to it．
The next step is to understand the link between your expectations and your frustration level．Whenever you expect something to be a certain way and it isn’t, you’re upset and you suffer．On the other hand, when you let go of your expectations, when you accept life as it is, you’re free．
A good exercise is to try to approach a single day without expectation．Don’t expect people to be friendly．When they’re not, you won’t be surprised or bothered; if they are, you’ll be delighted．Don’t expect your day to be problem-free．Instead, as problems come up, say to yourself, “Ah, another barrier to overcome．” As you approach your day in this manner you’ll notice how elegant life can be．Rather than fighting against life, you’ll be dancing with it．Pretty soon, with practice, you’ll lighten up your entire life．And when you lighten up, life is a lot more fun．
Why are people easily frustrated and anxious these days?

A．Because their children are disappointing．

B．Because they have to look serious in public．

C．Because life is becoming a greater burden．

D．Because people have lost sensible judgment．

According to Benjamin Franklin, what was the cause of over-seriousness?

A．The fact that people’s perspective, hopes and fears are limited．

B．The fact that people can’t change life itself．

C．The fact that things fail to meet people’s expectations．

D．The fact that circumstances turn out to be difficult．

In what pattern is this article developed?

A．Phenomenon, causes and solutions．

B．Problems, explanation and conclusion．

C．Examples, causes and arguments．

D．Phenomenon, analysis and conclusion．

What might be the best title for the passage?

A．People seem to be too serious

B．Life is simply as it is

C．Hopes can turn into difficulties

D．A good exercise removes over-seriousness

Three Japanese tourists taking a holiday in Australia got stuck when their GPS told them they could drive from the mainland to an island, failing to mention the 15 kilometres of water and mud in between.
As they drove their hired car from Moreton Bay in Queensland to nearby North Stradbroke Island, they started to notice the firm gravel（沙石）surface they were driving on giving way to the renowned bay mud．However, being confident that their GPS would direct them to a road soon, they decided to plough on, managing to travel around 500 metres before their Hyundai Getz（现代汽车）was up to its axles tires in mud．To make matters worse, the tide started to come in and soon forced them to seek help and abandon the vehicle．Just four hours later the car was trapped in two metres of water —— to the great amusement of onlookers on the shore and passengers on passing boats and ferries.
Yuzu Noda, 21, said she was listening to the GPS and “it told us we could drive down there．It kept saying it would navigate us to a road．But we got stuck…there’s lots of mud.” She and her travel companions Tomonari Saeki, 22, and Keita Osada, 21, instead had to give up their plans for a day trip to the island and headed back to the Gold Coast of a lift from the RACQ tow truck（吊车）driver who was called to the trapped car．No such luck for the hired car though – after assessing the situation, no attempt was made to recover it．The students from Tokyo, who are due to return home tomorrow, said the experience would not put them off returning to Australia for another visit．“We want to come back to Australia again．Everyone is very nice, even today.” Ms Yuzu said.
Remaining excited, Mr. Tomonari joked that the car may have got stuck because it was built in Korea．“Maybe if it was Japanese it would be okay,” he said．He added, “It has rained every day on our six day holiday．Hopefully next time we come back it will be sunny.” The car was covered by insurance, but the tourists will have to pay up to about $1500 in extra charges.

Dear Reader,
I receive many letters from children and can’t answer them all—there wouldn’t be time enough in a day．That is why I am sending you this printed reply to your letter．I’ll try to answer some of the questions that are commonly asked.
Where did I get the idea for Stuart Little and for Charlotte’s Web? Well, many years ago I went to bed one night in a railway sleeping car, and during the night I dreamed about a tiny boy who acted rather like a mouse．That’s how the story of Stuart Little got started.
As for Charlotte’s Web, I like animals and my barn（谷仓）is a very pleasant place to be, at all hours．One day when I was on my way to feed the pig, I began feeling sorry for the pig because, like most pigs, he was doomed to die．This made me sad．So I started thinking of ways to save a pig’s life．I had been watching a big grey spider at her work and was impressed by how clever she was at weaving．Gradually I worked the spider into the story that you know, a story of friendship and salvation（拯救）on a farm．Three years after I started writing it, it was published．（I am not a fast worker, as you can see.）
Sometimes I’m asked how old I was when I started to write, and what made me want to write．I started early—as soon as I could spell．In fact, I can’t remember any time in my life when I wasn’t busy writing．I don’t know what caused me to do it, or why I enjoyed it, but I think children often find pleasure and satisfaction in trying to set their thoughts down on paper, either in words or in pictures．I was no good at drawing, so I used words instead．As I grew older, I found that writing can be a way of earning a living.
Some of my readers want me to visit their school．Some want me to send a picture, or an autograph, or a book．And some ask questions about my family and my animals and my pets．Much as I’d like to, I can’t go visiting．I can’t send books, either—you can find them in a bookstore or a library．Many children assume that a writer owns （or even makes） his own books．This is not true—books are made by the publisher．If a writer wants a copy, he must buy it．That’s why I can’t send books．And I do not send signatures—I leave that to the movie stars．I live most of the year in the country, in New England．From our windows we can look out at the sea and the mountains．I live near my married son and three grandchildren.
Are my stories true, you ask? No, they are imaginary tales, containing fantastic characters and events．In real life, a family doesn’t have a child who looks like a mouse; in real life, a spider doesn’t spin words in her web．In real life, a swan doesn’t blow a trumpet．But real life is only one kind of life—there is also the life of the imagination．And although my stories are imaginary, I like to think that there is some truth in them, too—truth about the way people and animals feel and think and act.
Yours sincerely：E.B．White
