    An 18-year-girl Kayla Perkins explains what is in her bedroom, “I throw something on the floor and I know right where it is.” However, her parents, Steve and Deborah Perkins, of Mckinney, Texas, don’t think so. Even Kayla admits that, at the worst, her room is a mess.

Most families at some point have at least one child whose room looks like a landfill. 1. Dirty clothes pile up; dirty dishes get lost in the mess and smell bad; homework is lost; and valuable things are ruined.

Some parents let it go, believing that a bedroom is private space for children to manage as they wish. 2. What doesn’t work, parenting experts say, is constant lectures, verbal threats or getting very angry.

Mrs. Perkins says they picked up all the clothes on Kayla’s floor and hid them. They cleaned everything up. When Kayla came back to a bare bedroom, there was screaming and shouting, “How can I live without my clothes?” Mrs. Perkins asked Kayla to earn her clothes back by doing housework. 3.

4.  For example, since Jessica, the 14-year-old daughter wasn’t bothered by the dirty clothes all over her floor, the whole family started using her room as a place to store dirty clothes. Her attitude changed after her family did that. By the time she gave in and cleaned up her room a few days later, even she was laughing.

Parenting experts, Jim Fay, also recommends that parents first ask children in a nice way to clean up and agree on a reasonable time limit. 5.

A.Children often behave better if you treat them with respect and high expectations.

B.It’s easy said than done.

C.Humor can help, too.

D.Others lecture their children, offer rewards for cleaning, or punish them when they don’t.

E.The mess can disturb the whole household.

F.These days, she keeps her room clean.

G.Every family has different ways of dealing with it.

    Earlier this month, 6-year-old Isaac went on vacation to Fort Walton, Florida, with his family. While they were there, his mother Garrett learned about LuLu, a restaurant that offers food to customers with food allergies(过敏).

At LuLu, Isaac could eat a salad and a bowl of chicken soup with rice. “Isaac looked at me as if asking, ‘Is this OK?’ ” Garrett said. Once his mom gave the OK, Isaac enjoyed for the first time the experience of eating at a restaurant. “That look on his face was like, ‘This is the coolest thing I’ve ever done,’ ” Garrett added.

Garrett and her family rarely eat out because of Isaac’s food allergies. When they do, she cooks something for Isaac at home before they leave and brings it with her to the restaurant. “It’s not fun and it feels unfair,” she said.

Their night at LuLu marked a celebration for Isaac. Garrett shared the moment on the restaurant’s Facebook page. “Thank you from the bottom of my heart for giving Isaac this wonderful experience,” she wrote in her post.

Barnett, the restaurant’s manager, said, “When customers tell the staff that someone in their group has a food allergy, I assist with the order by passing it to the kitchen, ensuring it’s cooked in a separate station and delivering the finished food to the guests. We have been improving this process over the past ten years since our allergy program was started.”

On Garrett’s Facebook post, LuLu thanked Garrett for sharing her story. “Thank you for sharing your experience with us,” the restaurant wrote in a comment, “We are excited to see your son so happy!” Garrett is hoping her post’s popularity will persuade other restaurants to be more considerate. “LuLu takes it seriously as we take it – nothing could make us happier than that,” she said.

1.What does the underlined word “This” in paragraph 2 refer to?

A.Eating chicken soup with rice.

B.Eating at a restaurant.

D.Being on vacation with her family.

2.What will Barnett do when guests with allergies come to dinner?

A.He will personally assist with the order.

B.He will deliver the menu to them.

C.He will introduce the allergy program.

D.He will cook dinner in a separate station.

3.What can we learn from the last paragraph?

A.The popularity of her post made Garrett excited.

B.Garrett is unsatisfied with other restaurants.

    Does your local high school have a student newspaper? Only 1 in 8 of New York’s public high schools has student newspapers – and many of those are published just a few times a year. A few more are online, which can leave out poorer schools.

Rebecca Dwarka, an 18-year-old senior who works for her student paper said, “Facebook is the new way of finding out what happened. Nobody wants to actually sit down and read a whole article about it. This makes a ‘whole article’ sound a little like a long sentence in lonely places.”

I am not nostalgic(怀旧的) about high school student newspapers and never worked for mine. I put out what was then called a personal magazine with a group of friends because we wanted to write about peace, war and rock and roll without school officials warning us not to make jokes about the local officials.

School newspapers are in decline because students now find out what happened on social networking websites. This is a little discouraging because it proves that for millions of Americans, journalism is becoming a do-it-yourself thing. Every citizen can be a reporter.

When something happens, we look for social media messages. Facebook posts and Tweets have become the means by which citizens and reporters can prove, deny (否认), pass on stories and express opinions without the press’ challenging, researching or slowing the message.

But truly good journalism is a craft, not just a blog post. It requires seeing something carefully and it uses an eye for details to help prove a larger view. And even journalism that gives an opinion tries to be fair. If school newspapers begin to disappear, I hope there are other ways for students to learn that.

1.What can we infer from Rebecca’s words?

A.Students like reading detailed articles.

B.Facebook is the quickest way of spreading news.

C.School newspapers are becoming unpopular.

D.Long sentences are becoming popular in lonely places.

2.What does the underlined word “decline” in paragraph 4 mean?

A.Fall. B.Popularity

C.Increase D.Failure

3.What should good journalism do according to the author?

A.Ignore some details.

B.Spread a message quickly.

C.Act as blog posts in modern times.

D.Give an opinion in a fair way.

4.Which opinion does the writer intend to express in this passage?

A.Social media is becoming more and more important.

B.Everyone can become a reporter at present.

C.Social networking brings about new journalism.

D.High school newspapers shouldn’t be replaced by social media.

    The last African elephant at the Johannesburg Zoo, Lammie, lost her male partner to a sickness in September.

Lammie was born in the zoo 39 years ago. She had lived for 17 years with Kinkel, who died at age 35. Kinkel had been rescued in the wild after his trunk was caught in a trap in 2000. Around the time of her partner's death on Sept. 4, Lammie had stopped eating. The day before Kinkel died, she was seen trying to help him get up. Elephants are known for their intelligence, strong social ties and even the ability to mourn (哀伤). Some people argue Lammie should be sent to another place where she can be with other elephants.

Audrey Delsink is wildlife director of Humane Society International/Africa. She said, Lammie “is in desperate need of a happier existence and the chance to live out her years with other elephants.” Delsink added that a wildlife rescue place is ready to take Lammie if the Johannesburg Zoo agrees to let her go.

But the zoo says Lammie is staying. The zoo says it serves an educational purpose, especially for the poor who cannot pay to visit wildlife parks.

Michele Pickover disagrees. She is director of the EMS Foundation, a South Africa-based African wildlife rights group. She said “nobody learns anything” by seeing an elephant in captivity (被圈养). She said that watching a film about elephants would be more educational.

But, a spokeswoman for the Johannesburg Zoo, Jenny Moodley, says it is looking for a new partner for Lammie. She said the zoo is following guidelines in its search set by the World Association of Zoos and Aquariums. She added that experts are closely observing Lammie and that the elephant might not adapt well to a new environment. Moodley said of Lammie: “She is coping incredibly well, considering that she has lost her partner.”

1.What do we know about Lammie ?

A.She used to be rescued in the wild.

B.She lost her friends.

C.She was sad because of her partner’s death.

D.She has been sent to another zoo.

2.What will Audrey Delsink agree?

A.Use Lammie to educate poor people.

B.Let Lammie stay in the zoo.

C.Ask experts to take care of Lammie.

D.Let Lammie live in a wild life rescue place.

3.What does Jenny Moodley intend to tell us ?

A.Lammie has recoverd from the pain.

B.Lammie doesn’t need another partner.

C.Lammie will be sent away soon.

D.Lammie is well taken care of.

4.What can be the suitable title for the text?

A.Rescuing the elephant

B.The sad story of an elephant and her partner

C.Should the last elephant stay or go?
