Stay-at-home or working mom?

Nowadays, there is a heated discussion: Which is worthwhile, being a full time working or a stay-at-home mum? Readers share their opinions and you're welcome to add yours.

Catherine (China)

I love being a stay-at-home mom. In the beginning it was truly rough for me from being a workaholic(工作狂) to staying at home. Yet, I did not want my child to face growing up with both parents at work. So after discussing it with my husband, we decided that I would be the one to stay at home. Now, our daughter is soon to be 3 years old, and has an amazing personality. It's not for everyone but it is very rewarding in the long term.

Sassy(Canada)

Taking care of children is a temporary job, and children will grow up and leave. The longer women are out of the workplace, the harder it is to enter it. Women need to realize and accept that you do not want to be dependent on anyone for basic food, clothes and shelter. It has been hard to work and take care of my kids but I make it work.

Cynthia (US)

Some days I think we shouldn't give up on our careers. And some days I'm jealous of the moms who get to stay home or at least work part time. I'm the only one that supports the family, so there will never be an option for me. I have the career and title I've always wanted but now I can't help but think it's at the expense of precious time with my family.

Celina (US)

Being a stay-at-home mom isn't always easy, but it is worth it! Being there with my children means they are getting the exact love and care I want them to have. We do not have a lot of money, but we've sacrificed to make it possible.

1.What can we learn about Catherine?

A. She stayed at home because she was tired about her job.

B. Her daughter was very naughty.

C. Her husband agreed with her staying at home.

D. She accustomed herself to staying at home easily.

2.How many working moms in this passage?

A. 1　　 B. 2

C. 3　　 D. 4

3.Which one is NOT true?

A. Celina feels dissatisfied with the life now.

B. Cynthia has no other choice but to get a job.

C. Sassy is determined to be an independent woman.

D. Catherine thinks that being a stay-at-home mom is worthwhile.

（题文）After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

What does the underlined word ＂displaced＂ in paragraph 2 mean?

A. Tested.　　 B. Separated.

C. Forced out.　　 D. Tracked down.
