Diet and way of life are often a problem for teenagers. However, if you eat the right food and exercise regularly, you can feel better, look better and have more energy. So healthy eating along with regular exercise is     1     (probable) the first step to become fit.

As a teenager, it is necessary     2    (eat) healthily and give your body the energy it needs. For a healthy diet, you should eat mostly rice, bread, vegetables and fruit. The important thing to remember when you choose food is to protect yourself from some     3     (trick). A number of people out there who want to make quick money are always fooling you into     4     (believe) what they say so their products can sell well. Don’t be tricked     5     them. What you need is just to trust a diet that is right for your body.

Exercise is also something on     6     you can depend to make you look good, feel good and be healthy. It is obvious that exercise is beneficial to you. When you exercise, you build up the     7     (strong) of your muscles and your body produces some chemicals that make you feel peaceful and     8     (relax). Follow     9     suggestions above and you will look and feel much     10     (good) in no time.

The new semester has begun, and it’ll be a fresh start for you.

First of all, congratulations! You’ve successfully graduated as a junior — now the hard work really     1     (begin). You’re probably feeling     2     (excite) or maybe a little nervous about the school life     3     is waiting for you at senior high. What everyone mentions is the increased workload (课业压力), but senior high is not all about the national college entrance exam (高考). In fact, it is about preparing     4     the future and shaping     5     (you) into the person you hope to become. In junior high, you followed your teachers’     6     (instruct). But as     7     senior, you are expected     8     (think) and study     9     (independent) — how you organize your study notes and how often you study are up to you. However, studying is not all. The first year in senior high offers many development opportunities.     10     (join) in various activities can enrich your school life, help you to make new friends, and broaden your horizons (开阔眼界).

Making friends is a skill. Before you make friends, you have to decide     1     you want to be your friends. Most people like to have friends who like to do the same kind of things as they do.

Of all methods, the     2     (quick) way to make friends is to smile. When you smile, people think you are friendly to them and easy to get on     3    . It may not be easy to smile at first, but remember most people will stay away from     4     angry-looking face. To talk with others is a good way to make friends, too.     5     (start) a talk with someone, you can say something nice about him. Think about how great you feel when someone says something nice to you. Doesn’t it make you want to keep     6     (talk) to that person?

Ask your new friends some questions about     7     (they). Who are their favorite singers? Where do they live? What do they     8     (usual) do after school? There are all good     9     (topic) to start a talk. Make sure you have something to add to the talk, too. When someone     10     (ask) you a question, you’d better have an answer for him. Remember that nothing will stop a talk more quickly than a shrug (耸肩) for an answer.

To raise snails(蜗牛) well, you need to spray water to the container every morning and evening, change soil every two weeks, and feed them with cabbages and sweet fruits — this is     1     Sun Youxiang, a fourth-grade primary school student in Hangzhou, concluded after raising snails for one year.

From three white jade snails at the very beginning to more than 60 snails of four     2    (generation) now, he has done a great job in his assignment for his science class. Witnessing the reproduction of animals     3    (be) a precious experience for kids. Their creativity,     4    (patient), and respect for life will be stimulated(激励) as they learn to take care of animals on their own. Sun’s teacher said     5     assignment served as a good example of life education. Practice is an essential step in learning, which will benefit the kids for a life time.

Life education allows kids to know how     6    (live) with nature and creatures in a friendly way. Starting from this year, science will become an     7    (equal) important subject as Chinese and Math in primary schools, which     8    (aim) to improve students’ knowledge about the surroundings.     9    (draw) by curiosity, more kids will be willing to observe and think through practicing, which will add     10     our recognition of the world in the long run.

How do learning habits influence learning results? It's useful and necessary to discuss learning habits. There is a famous     1     (say) “Good habits lead to good endings”, which shows the importance of habits.

“An apple a day keeps the doctor away.” also     2     (show) a healthy everyday habit helps to build up our body. Thus, good learning habits can help us gain great learning results, high scores and abundant knowledge     3     (include). At first, learning habits form our ways of thinking and attitude     4     the content of our learning.     5     (obvious), a good habit can help us to speed up to reach our destinations. As we can see, developing a good habit is so important that I would like to introduce one kind of good learning habits --- keeping     6     learning diary every day. We can start the habit by     7     (write) a learning summary and remember to record something impressive and meaningful. Keep it in mind,       8     gradually we can gain this good learning habit and benefit from it.

What's     9     (much), I find out that I still have some bad learning habits     10     well. I can only concentrate on reading for a short time, and I will conquer this problem by spending more efforts on concentration practice.

I believe that through my efforts, I can gain good learning results by having good habits.

Today, we will examine some     1     (use) no-cost things you can do before you study to help you improve your memory and learning. Three important ideas     2     (think) about before studying include exercise, study place and pre-study tests.

Before you study, doing cardiovascular exercise (有氧运动) may help you better remember what you learn. Violent exercise may be especially helpful. So far, researchers have suggested combining     3     two to get the best effects for your memory. The important idea is this: exercise     4     (be) good for your memory.

Where you study is also important for improving your learning. Researchers find that     5     (surround) play big part in how well people remember the words. Although     6     is good to have a desk or a special study area, some research suggests that changing where you study could help you remember     7     (much) of what you study.

Testing is good way of     8     (make) yourself remember new information. In 2018, researchers found that students who took a test before learning a new material did much better after studying the material. The students failed the test, but they were better able to remember the material than students who     9     (ask) only to read the information. So try to take a pre-study test. While you might not know the answer, you will probably be better able to learn and remember the answer when you study it     10     (late).
