When Lucy and Maria Aylmer tell people they are twins, disbelief is the response. The 18-year-olds from Gloucester, U.K. are two of the five children born to their Caucasian (白种人的) father and "half-Jamaican" mother. While their other siblings (brothers and sisters) have a blend (混合) of features from their parents who have different skin colours, Lucy and Maria are unique: Lucy has fair skin and red hair, while Maria has brown skin and dark hair.
"No one ever believes we are twins because I am white and Maria is black," Lucy said. "Even when we dress alike, we still don't look like sisters, let alone twins. When we meet friends for the first time they all refuse to believe we are twins and some have even made us produce our birth certificates to prove that we are really twins."
Unlike identical (同卵的) twins, fraternal twins are bom from two separate eggs. The BBC reports that for a biracial (双人种的) couple expecting twins, there is about a 1 in 500 chance those twins will have different skin colors.
The Aylmers are proud of their uniqueness.
"Now we have grown older, even though we still look so different, the bond between us is much stronger," Lucy said. "Now we are proud of the fact that we are each other's twin sister. Maria loves telling people at college that she has a white twin sister — and I'm very proud of having a black twin sister, too."
Lucy and Maria are unique because _______.

A．they are fraternal twins

B．their siblings are all black

C．they are hybrids of multi-racial parents

D．they are twins with different skin colours

How do people usually react to the twins' physical appearances?

C．They find it unbelievable.

D．They regard them as lucky dogs.

What can we learn about Maria from the text?

A．She comes from Jamaica.

B．She was born of biracial parents.

C．She bears mainly features other father.

D．She shares a birth certificate with her twin sister.

If your job requires a lot of sitting, you could be putting your health at danger.
The American Journal of Epidemiology (流行病学) did a study in 2010 on the correlation (相互联系) between sitting and an individual's physical health. In the study, 53,440 working men and 69,776 working women were surveyed on their time spent sitting. The subjects were all disease free when employed. The researchers identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up.
The findings: Women who reported sitting for more than six hours per day had an approximately 40 higher all-cause death rate than those who reported less than three hours a day, and men had an approximately 20 higher death rate.
Well, now's a fine time to get this information. But why didn't they tell me this years ago? I would have planned on taking a more active job instead of the sedentary (坐着的) job of an editor.
So what can you do if you have to work for a living at a job that requires a lot of sitting? Here are some ideas:
Take frequent breaks. It is recommended that workers vary activities, change their position, and take short breaks every 20 minutes to rest muscles and increase blood circulation. Get a standing desk. Some studies have shown that working from an upright position may be better for health. The serious fitness people can even purchase a treadmill (跑步机) desk. It only goes about one mile per hour. Have a walking meeting. If your group is kind of small, going for a walk while discussing topics is a good alternative.

In 1992, I had just launched a new business called Video News International.
It was the world's first video journalist network. The idea was to cover news and sell the service to news organizations.
One day, a young intern (实习生) who was working for us named Anthony Lappe pulled me aside.
"There is something you have to see," he told me. "Comcast is doing this really cool thing."
"What?"
"The Internet," he said. "It's going to be really big."
Anthony later introduced me to the head of the Internet project.
"We are looking for content to put on our network here," the guy said to me.
Well, I said I had lots of content to offer.
The guy's eyes lit up. "Cool," he said. "We would like to put it on our network."
Well, I was always looking for new clients.
"What are you going to pay?" I asked.
He said that they could not pay anything for the content, but they would set up a URL for me.
"What's that?" I asked.
"It's kind of like your address on the web."
"What would I do with this URL thing?"
"Well, it could be your business."
"I don't see how it is a business, and there's not even any advertising," I cleverly replied.
"Not yet," he said. "But one day there might be."
I thought about it for two seconds.
"Naah..." I said. "I've got bigger fish to fry. I've got to be going now. Maybe we can cooperate next time."
And I walked out.
Idiot!
Well, that Internet thing turned out to be so much bigger than I had thought. I wish I had never made such a mistake. Sorry Anthony. You were right.

My friend had mentioned the other day that her father had a lot of children's toys he was looking to give away. She knew I have a three-year-old daughter so she thought of me first. I told her I would love it if I could get some nice things for my daughter, which I wouldn't otherwise have been able to afford.
When I met her father, he began to explain he was too poor once and that he would hate to throw away things that can be very useful.
Before he showed me what he was giving away, I thought the toys would be mostly lego's(乐高积木) or things like that. When he was showing me around I saw a bed, a slide, a kitchen set and many other things that just blew my mind. He told me to write a list of everything my daughter could use and as my eyes were wide, he told me not to feel guilty. He said I was helping him by getting rid of the stuff.
As I was looking around I did feel guilty, but I tried to remain more grateful than guilty. Every time I tried to thank him for giving me and my daughter all this wonderful stuff he would thank me right back. I wanted to believe that he was just thanking me so that I wouldn't feel so guilty but in reality I believe that he was as grateful as I was that these toys would be put to good use.
In the eyes of charity, it makes sense to feel grateful, but guilt is just as normal. I know that we could have lived without a slide, which is why I do feel guilty, but I am grateful all the same because my daughter really does enjoy all these nice things!
Why did the old man want to give away his toys?

A．He wanted to help those poor children.

B．He was wealthy enough to buy new toys.

In the writer's opinion, the old man felt grateful because________.

A．he wanted to make her more guilty

B．he wanted her to take the toys quickly

C．the toys would be put to good use

A．The writer took all the toys home.

B．The old man was a kind and thoughtful person

C．The writer wanted to refuse the stuff when she first saw them.

D．The writer's daughter enjoyed the slide most among all the stuff.
