Because earthquakes happen without warning, it’s important to take steps now to prepare.
Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
A person needs at least 1 or 2 gallon of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
It’s always a practical idea to keep food that can be stored easily. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights(手电筒) and spare batteries.
Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake. Maybe it’s dangerous. Prepare a battery-powered radio and spare batteries. Most telephones will be out of service, so radios will be your best thing of information.
4. Clothes.
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
| A．Because earthquakes can be known before they happen. |
| B．Because earthquakes take place without warning. |
| C．Because earthquakes take place at times |
| D．Because it’s people’s daily work to prepare the earthquakes. |

We go to school every day to become a better person. So how can we become powerful and start changes in our own life? Perhaps we can get tips from the US First Lady Michelle Obama. During her visit to China, from March 20–26, Mrs Obama shared her views on education with students.
The first lady encouraged Chinese students to aim high and get a good education. In Chengdu No 7 High School, she told students that having poor roots doesn’t matter as long as you have perseverance (毅力).
Mrs Obama said her family was not rich. Like many Chinese students, her parents had big dreams for her. She felt the weight of her parents’ sacrifices (牺牲) on her shoulders and worked hard to make them proud.
Persevering was not easy, though. Sometimes she had to wake up at 4:30 a.m. and study late into the night. “But whenever I got tired or discouraged… I would remember something my mother always told me. She said: ‘A good education is something that no one can take away from you.’”
Mrs Obama also encourages Chinese students to study abroad. “As the Chinese saying goes: It is better to travel 10,000 miles than to read 10,000 books,” she said. It’s not enough to get good grades in school. It’s also important to have real experience with languages, cultures and societies different from your own, she noted.
Studying abroad could also gain future international relations. It could help young people from different countries work together to deal with problems such as climate change, Mrs Obama said.

Mark Twain is someone Americans are taught to love. Older relatives, English teachers and the media always praise (表扬) him. But when you actually take the time to read The Adventures of Tom Sawyer, you find that his work is more wonderful than you could ever imagine.
The novel describes a young boy named Tom Sawyer growing up in a small town along the Mississippi River. He explores the countryside on a riverboat with his friends, falls in love with girls, starts secret clubs and searches for treasure. Twain’s idea of childhood is magical – a time of imagination, wonder and, of course, adventure.
More importantly, through the eyes of Tom Sawyer, Twain cleverly makes fun of US culture. For example, Tom hates going to church, and Twain uses scenes of Tom there to mock religion and its old traditions.
Twain’s writing is full of these kinds of critical (批判的) points about culture and politics. That’s why he is so loved in the US – he wasn’t afraid to state his opinions, and he did so clearly.
He also believed strongly in women’s right to vote in elections and gave a famous speech on the subject, called “Votes for Women”, in 1901.
“Tom was a great hero once more – the pet of the old, the envy of the young,” Twain writes in Tom Sawyer. But he could just as well be describing himself.
