If you have a cat, you already know that a cat isn’t a dog that doesn’t have to be walked. If you’re about to bring a cat into your family, you need to understand that basic fact. The common wisdom is that dogs are friendlier than casts.

In recent years, scientists who have done DNA studies have offered a better way to understand cats. Unlike other animals that people feed, cats domesticated themselves, and, in a way, trained humans. Cats decided to live close to humans because doing so benefited the casts themselves.

Studies show that cats have lived with humans for about 12,000 years, since people first settled down and started farming. When people started storing grain, mice arrived and started eating the grain. Clever cats figured out that mice settlements where people stored grain were easy for hunting, so they started hanging around. Cats did what they needed to do to get the people to let them stay, but they kept up their independence. Over time, cats allowed humans to get a bit closer to them. Later, the farmers did befriend the cats. Certainly, it didn’t do them any harm because they could see the cats were really helping them out by eating mice.

Today, about a third of American families have cats. In most of those homes, the cats are still more interested in pleasing themselves than in pleasing their human families. A dog may do anything it can to make you happy, but kitty will teach you to make kitty happy.

1.Compared with dogs, cats are______.

A. colder B. friendlier

C. more warm-hearted D. more frightening

2.According to the text, why do cats decide to stay close to humans?

A. To be useful to themselves B. To protect grain from mice

C. To rely on humans for food D. To keep up their independence

3.What may be the best title for the text?

A. A common point between dogs and cats

When Nancy Flexer opened the door to her classroom near the end of her final school year, all 41 years of her career as a beloved first-grade teacher came to life right in front of her.

Cole Elementary School in Tennessee surprised Flexer with a memorable and emotional retirement party featuring former students of all ages, dating back to the first class she taught in the 1973-74 school year. A video of the event shows an overwhelmed Flexer being moved to tears as she hears former students who are now adults tell her how much she affected their lives.

"I'm one of the luckiest people in this world," Flexer said. "I remember I opened the door to the classroom thinking no one was in there, and it was wall-to-wall people and banners and everything. It was the coolest thing that could've ever happened in my life. How many times do we really realize the lives we've touched, the manner in which we've touched them, and that these are memories that stay with them for life?"

Despite being young when they were taught by Flexer, students easily recalled the heartwarming notes she wrote them on report cards, the ways she helped them overcome shyness and awkwardness, and how she inspired them to future academic success to earn scholarships and advanced degrees.

Even though Flexer hadn't seen some of the former students for decades, she instantly remembered the names of every single one there.

A scrapbook(剪貼簿) of her career was presented to her as one student after another recalled the effect Flexer had on his or her life.

“I’ve had many opportunities to move to a school closer to my home, but I said ‘Cole gave me so much in my life that when I retire, I will retire from Cole school and give back what’s been given to me.” Flexer said. “My career could’ve taken me nowhere that would have made me happier. I think of it as a blessing.”

1.We learn from the text that the retirement party__________.

A. was beyond Flexer’s expectations

B. attracted many of Flexer’s friends

C. was full of appreciative parents

D. was organized by Flexer’s students

2.Flexer’s former students ___________.

A. helped her overcome her shyness

B. presented her with cards

C. held a party to express their happiness

D. bore her help and inspiration in mind

3.What can we infer from the last paragraph?

A. Flexer missed many chances of further studies

B. Flexer once studied in Cole Elementary School

C. Flexer loved her teaching career in Cole

D. Flexer refused many other school’s invitations

4.What would be the best title for the text?

A. An interesting party

B. A teacher’s 41-year teaching career

C. Students’ memories of their beloved teacher

D. Students fro 41 years surprise their beloved teacher
