2 . How to make friends at a new school

Starting with a new school can be difficult. Everything seems to be different, and you don’t even know where to go for your own class.     1    if you use these skills, you can quickly turn some of those strangers into friends.

Be yourself.

    2    If some people don’t accept you, they’re not the kind of friends you need. People often stay together because they have similar interests. For example, someone who does a lot of sports may make friends with those who also run or swim a lot.

    3    

Remember to be nice to the people you meet at your new school. If you think that you will say something that may make them feel sad, do not say anything and just nod your head if they talk to you. Also, remember to be as helpful as possible.

Believe in yourself.

A smile goes a long way. When you walk in the halls, don’t keep your eyes on the floor. Raise your head and make eye contact (目光接触) with other people If you see someone you know, smile or say “Hi” Introduce yourself,     4    

Remember people’s names.

You like it when people use your name, and so do other people. People may become angry if you just begin by saying “Hey” each time. Besides, ask them in a kind way if they have a nick name. You’d be surprised how often this might come in handy.

3 . A student from Phoenix learned a life-saving skill in his health class. It was the skill he learned that helped him ________ a teacher’s life.

It was a school day. Two ________ took a walk around the campus during the lunch break. One suddenly lost consciousness (知觉) and ________ to the ground, the only thing the other teacher Ellen could do was cry for help because it happened too ________. Two girls near Ellen immediately ran to the ________ to ask for help. When they arrived, some students in the gym were doing ________. Hearing the two girls’ words, Salim Mohamed and his coach hurriedly ________ to help.

Salim ________ the girls who called for help and saw the teacher ________ lying unconscious. All he knew was that her heart had stopped, so he did the most logical step he knew that could help—chest compression (胸外按压). He said he learned it in his ________ class. While Salim was doing that, Ellen was on the ________ and called 911. The operators gave Salim further ________ while waiting for the doctors to arrive.

The teacher regained consciousness before being taken to the hospital. It turned out that she ________ a heart attack. But thanks to Salim’s quick action, she was able to recover.

Doing CPR (心肺复苏) or chest compression may seem ________, but Salim said it should be a skill everyone must learn. “CPR is just a(n) ________ thing. Everybody should know how to do it. It is easy,” he said in an interview.

4 . As a medical student at Gadjah Mada University, I spent most of my time studying in classrooms. So I didn’t _________ speak with patients in hospital. Then I _________ to visit the neurology ward(神经内科病房) at Dr. Sardjito Hospital.

One cold evening, I was in the ward, looking for a stroke (中风的) patient, whom I would call Ms A, to gather some _________ information for my study. Holding a form, I walked into her room. Ms A was lying on the bed, _________ still weak. There were no relatives with her. In a(n) _________ voice I asked how she was going. She softly replied that she was getting better.

After I finished, I prepared to leave. Before I could _________, Ms A started talking about herself. She shared her difficulties and _________, talked about her husband, who was killed in a car accident. Without being _________ of it, I had begun holding Ms A’s hand. Since I didn’t have anything to say, I just sat quietly while she was talking. That’s when it _________ me that she just wanted me to listen. All I did was to nod my head as a way of showing my __________.

Finally, Ms A stopped talking. “I’m very sorry for keeping you listening to my problems, but I feel better with some __________ now.”

I still held her hand and __________ at her, saying “It’s OK, Ma’am. It’s part of my duty.” Then I stood up and waved goodbye to her.

However, I’ll never forget what the __________ has taught me. Sometimes patients don’t necessarily need expensive medicine or __________ technology. They just need someone with the patience to __________ an ear and spare a little time to them.

5 . In July 2021, astronauts on board the International Space Station (ISS) planted pepper seeds as part of an experiment to test which plants could be successfully grown in space. The peppers were harvested four months later, and the team celebrated with a party and taste test.

For astronauts living mostly off prepackaged foods for months at a time on the ISS, fresh and flavourful produce is welcomed. With long missions to the Moon and Mars in focus, NASA is working to find sustainable ways for astronauts to enjoy fresh foods, which will add key nutrients to their diets and improve their state of mind.

Astronauts have grown radishes, zinnias and a variety of lettuces on board the ISS before, but this is the first time they grew peppers, which posed a new challenge, reports Elizabeth Howell for Space. com.

Biologists at the Kennedy Space Centre spent two years picking the perfect pepper. They wanted to try peppers because they’re a great source of vitamins and nutrients, and they can be eaten raw or cooked. Plus, peppers are fairly low maintenance to grow.

In June, a carrier delivered supplies to the ISS along with a package of 48 pepper seeds. Astronauts on board planted the seeds in a microwave oven-sized growing container. The conditions in it—such as lighting, watering and air circulation—were controlled by a crew based at the Kennedy Space Centre. On board, the astronauts collected data and offered feedback on the flavour of the peppers.

“This is important because the food astronauts eat needs to be as good as the rest of their equipment,” LaShelle Spencer, a plant scientist at NASA, said over the summer. “To successfully send people to Mars and bring them back to Earth, we will not only require the most nutritious foods, but the best tasting ones as well.”

6 . Habits to Be a Highly Effective Student

Some students are able to get straight A’s and at the same time serve as the president of three clubs. However, some students struggle to keep their GPA(grade point average)above 3.0.     1     Although it’s true that everyone’s IQ is different, good study habits are very important. Here are several habits you should adopt to get good grades.

    2     If you haven’t had a “planner”, get one. Many people use their computers and smart phones to make a schedule. The problem with that approach is that they are major distractions(使人分心的事物). Instead, get an old-fashioned paper and pen planner.

Create a weekly schedule.     3     Include time that will be spent eating, sleeping and doing anything not related to schoolwork. That way you know exactly how much you can achieve each day.

Take frequent, short breaks. Taking a break from studying for 15 minutes every hour will help keep you refreshed.     4     If you don’t take a break, you may find yourself daydreaming or even falling asleep. Take some time for some water, a snack or a quick chat with a friend.

Take care of yourself. During the final exam week, it is common for students to fall behind on sleep and meals. Make sure you get a good night’s sleep and have regular meals. Studying while you are hungry or sleepy is ineffective and will slow you down in the long run. Also try to make the time for family and friends.     5    

Learning our school is going to hold an summer camp during the vacation, I’m really interested on it. There is so many wonderful courses, including gardening, cooking, self-defense but nursing, which are all so very useful to us students.

Now, I have decided apply for the cooking course. I want to learning how to cook delicious foods. Besides, with the knowledge of cooking, I can help my parent cook supper, which will make them happily. I’d appreciate it if you could be offered a chance to join the camp.

Yours,
