Friendship is one of the most important     1     (thing) in everyone’s life. It is very difficult     2     (find) a better definition（定义）of friendship. A true friend is the person     3     can share all our sadness and double all our happiness. In time of trial(尝试） , he or she is always at our side to give us his or her help and comfort.

    4     (know) how valuable friendship is, we should be very     5     (care) with our choice of a friend. We should choose those people with a good character     6     our friends, but we must try to avoid making friends with a bad man.

Besides, we should forgive their mistakes and try to help them as much as possible. A true friend can always be trusted, loved and     7     (respect). If you tell a friend your secrets, he or she won’t tell anyone . Friends share their joys and sorrows. They help each other when they are     8     trouble, and cheer each other up when they are sad.     9     most important thing is that a friend always understands you. In conclusion, If you have made a good friend, don’t forget     10     (he) or her.

At each stage of our life, we meet different kinds of people. Some are funny; some teach us lessons in life while others occupy a special space in our heart. The people     1     (call)“best friends” are just these special     2    (friend).

In our childhood, “best friends”might have meant the persons who are always by our side, whether it may be in the classroom or in the dining hall. However, as we are getting     3     (old) than before, our definition(定义)of “best friends” changes. In my opinion, best friends are those who love you     4     who you are and help you become who you should be. People in our life come and go, but some people stay. They are the people we should never lose.

True friends are those     5     will never leave you when you need them most. They are always there waiting for you and they love you when you forget to love     6     (you). The best feeling in the whole world is knowing that there is     7     person who always prays for us and always keeps us in his/her thought. Friendship may not     8     (necessary)be based on age, but it is based on     9     (understand). Even our parents also can be our best friends! So let us build our friendship and try our best     10     (see)the good side of everyone!

I met up with a lovely Australian gentleman again on my walk this morning.    1    (actual), I see him almost every morning. When I first saw him    2    (month)ago, he walked by me quickly and didn't look at me at all. I know he is not good at Chinese and I figure that's why he might have been anxious about    3    (make) eye contact.

I don't know any Australian so I would always just walk by with no contact as well. Then one day I stopped    4    (say) "Nihao" to him and smiled at him. He looked at me and with the    5    (big) smile I have ever seen, he shyly said, "Nihao!" He,    6    was polite and friendly, looked like a different person. We made contact! After that, when we    7    (run)into each other, we exchanged "Nihao".

This morning I saw him just from a distance and I tried waving    8    him since we were too far away to say "Nihao". Well, he was so happy when he saw me waving and he walked up to me in excitement. I saw his bright smile. In    9    (break) Chinese, he asked me whether I could teach him Chinese and said that Chinese is indeed a beautiful language, broad and profound. I agreed. This surely made our happy morning and I bet he smiled all    10    way to the bus stop!

Once 50 people were attending a lecture. Halfway through his talk, the speaker stopped and decided     1    (create) a group activity. He went around the hall and gave each person a balloon. Each one was asked to write his or her name on the balloon     2    (use) a marker pen. Then all the balloons    3     (collect) and put in another room.

The speaker then led the group     4     the room full of balloons and asked them to find the balloon that had their name written on within five     5    (minute).   Everyone was    6     (hurry) searching for their name, bumping into each other, pushing each other around. It was chaos. At the end of the five minutes no one could find     7    (they) own balloon.

Now each person was asked to randomly collect     8    balloon and give it to the person     9     name was on it. Within two minutes everyone had their own balloon. When everyone quieted down, the speaker began to talk, saying that this is exactly what was happening in our lives.

We may like to think of ours     10     (important) than others, but our happiness sometimes lies in the happiness of other people. Give them their happiness and you will get your own happiness.

We always think it’s OK for us to leave our plants unattended during our vacation,but a recent study has led to a new     1    (discover).

Some scientists tested tobacco plants and tomato plants by cutting off their stems(茎)and     2    (stop)watering them.They then recorded their response with a microphone       3    (place)ten centimeters away.

They found that the plants began to scream ultrasonic(超声波)sounds, which they believed could convey their suffering     4     other plants.When the stem of a tomato plant was cut,the scientists found that     5     screamed 25 ultrasonic sounds of suffering within an hour.The tobacco plant that had its stem cut     6    (send)out 15.

The plants also seemed to respond to different     7    (stress)with the different intensities(强度)of sound.The scientists observed that the tobacco plants let out       8    (loud)sound when they were not watered than when they had their stems cut

The study answers the question     9    plants can feel pain or not.It can change the way that we think about the plant kingdom,which has been     10    (natural)considered to be almost silent.

In 1955, I got a train ticket to visit my relatives in Cleveland. On my return trip, I met     1     handsome soldier. He asked if he could look at the train timetable     2     was held in my hand and then if he could sit next to me so that we could chat. I agreed and invited him to share the lunch my aunt     3     (pack) for me before leaving. We talked all the way. Finally, we exchanged     4     (address) and he said he would contact me.

After a week, I still didn’t receive a letter     5     him and began to think he’d forgotten about me. On Saturday, the phone rang and a familiar voice asked if I would like to go out together. We ended up in     6     (see) On the Waterfront at the Kallet Theatre. We had a more dates during his Army leave, and then he     7     ( send) to go overseas. For the next to years, we kept in touch with each other by letter.

In 1957, we got married. We’ve been together for more than 60 years, raising three daughters who now have daughters of     8     (they) own. Before taking my trip to Cleveland years ago, I was warned never     9     ( speak) to strangers on a train. I’m     10     ( certain ) glad I didn’t listen.

How are you getting along with your high school? It may be hard for you as this is the first time that you     1    (leave) your parents. I know that you are now having trouble     2    (communicate) with others. That’s    3     you are new here and people don’t know about you. But I think you can follow the advice below.

First, you should take     4    active part in the discussions and show your own opinions about the matters, and at the same time, learn to listen to other people’s views    5    (careful). Second, you should learn about your classmates’ likes and dislikes,    6     can make you get familiar with them. Only in this way can you get to know more     7     (difference) people and show them that you are just as friendly. I’m always here ready to help. We can take part in some    8     (activity) together and I can introduce you to others.

There’s no need       9    (worry) too much. People will know you more very soon and will like to make friends     10    you if you can do as the above.
