Classes resumed (恢复) Thursday for the students of a school in Newtown, Conn, where a gunman last month killed 20 children and 6 adults in the second-largest school shooting in U.S. history.
With their school still being treated as a crime scene, more than 400 students of Sandy Hook Primary School attended classes in neighbouring Monroe.
Returning students, teachers and administrators were met by a large police presence outside their new school. Several officers guarded the entrance and checked IDs of parents dropping off children.
Law-enforcement officers guarding the new school called it “the safest school in America.”
Students found the same chairs and desks, when possible. Their classroom walls were painted the same colours and hung with the same pictures. Other details, such as the location of bookshelves and cubby holes, were replicated (复制) as much as possible.
The school district said parents who wanted to be close to their children were welcome to visit and stay in classrooms or an auditorium.

A year ago，I paid no attention to English idioms (习语), though my teacher told us the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.
One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be surprised. Gently shaking his head，shrugging his shoulders, he said，“You don’t say!” “You don’t say!” I was puzzled. I thought , perhaps this is not a right topic. “Well, I’d better change the topic.” So I said to him. “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was wonderful.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it.” Soon I was interrupted (打断) again by his words: “You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t ask you to do so,” he answered, greatly surprised. I said, “Didn’t you say ‘you don’t say’？” Hearing this, the Englishman laughed to tears. He began to explain, “ ‘You don’t say’ actually means ‘really!’ It is an expression of surprise. Perhaps you don’t pay attention to English idioms.” I realized I had made a fool of myself. Since then I have been more careful with idiomatic expressions.

It’s a long-awaited day for China. The navy now has its first aircraft carrier(航空母舰), Liaoning.
It’s a unique experience to get to know the life in the carrier. The carrier is just like a small city on the sea. It has all the functions for daily life. There are 4 words to sum up its characters: big, small, much and high. The carrier Liaoning is such a huge one that the total length of the whole corridor（过道）could reach over 20 kilometers. But the living space for the sailors（水手）is quite small. That’s because the carrier is designed for researching purposes, rather than comfortable living. Over 1,000 sailors, both men and women, are living onboard. They are arranged among over 3,000 tiny rooms below the deck. For visitors, it’s so easy to get lost. So the first thing the new sailors have to learn is their way around. The number of female sailors is much less than that of the males, taking about 5 percent of the total. But they play a key role in carrying out some special missions.
Also, you will be surprised by the high level of education of today’s sailors. The captain said that over 90 percent of the sailors are college graduates. Six hold Doctor’s Degrees and 45 have a Master’s. The whole team is young but vigorous. The complex work on the carrier requires high management abilities for the commanders onboard(在船上). Why do we visitors get lost easily inside the carrier?
| A．Because they don’t have a map. |
| B．Because the living space is quite small. |
| C．Because there are too many corridors for rooms. |
| D．Because the corridor inside the carrier is too long. |
What does the word “high” in Line 6 refer to（指代）？
| A．The aircraft carrier is high since it is just like a small city. |
| B．Most of the soldiers received good education. |
| C．The expense（花费）to run a carrier is high. |
| D．The high-level of their training. |
Which of the following is NOT TRUE according to the passage?
| A．Liaoning is our country’s first aircraft carrier. |
| B．Most of the sailors on the carrier are college graduates. |
| C．There are far fewer women sailors than men sailors on the carrier. |
| D．It is comfortable for the sailors to live in the carrier. |
Yesterday the police were joined by more than 20 volunteers in the continuing search for the two missing teenagers, Vicky Gray and Tom Hunter, and their guide, Gavin Jones. The police said that they had disappeared during an adventure tour of Cape York Peninsula.
This was the second day of the search and the police were now very worried about the safety of the three missing people.
The police said that the search had covered a wide area, but the rainforest was thick and their work was made harder by the recent rain. Later on Chief Inspector (警官) Roger Fleet said, “The travelers had a radio with them. If they had been in trouble, they would have called us.”
The three travelers left Cooktown very early on Saturday morning in a Toyota car. They took a small dirt road that runs down to the Daintree River, a dangerous river full of crocodiles (鳄鱼). Chief Inspector Roger Fleet said the tourists wouldn’t have got into trouble if they had stayed on the main road.
A photo of Vicky and Tom was found by a policeman under the “Be Careful about crocodiles” sign near the river. Why was the photo left behind? This is just one of the unanswered questions. Other questions are: Why was the Toyota parked and locked at the edge of the rainforest? The police said that the travelers had left a map of the area behind. Why? Why had someone drawn a cross on the place where the car is? Is this a sign? What does it mean? If anyone can give information or has seen these three young people, contact the local police in Cooktown.This article is probably taken from ________
| A．a newspaper | B．a magazine | C．a storybook | D．a guidebook |
Which word best describes the search of the three missing people?

Which of the following things wasn’t found by the police?

All the following questions are unanswered except________.
| A．why they left a photo behind |
| B．why they came to this area |
| C．why their Toyota was parked in the place |
| D．why a cross was drawn on the map |
