My brother is really     1    (勤奋的).He often works in his office far into the night. Recently, he and his team have decided to have another     2    (造纸的)factory set up in this town.They found that there were more     3    (新建的) houses in this village than in that one, and a lot of     4    (过路人)were     5    (成年人).In order to find some suitable workers, they decided to hold an     6    (800米的)race next week.

I used to be a lazy student who often fell asleep in class. Worse still, I associated with bad friends. As a result, I was     1    (落后的) in my studies. It was not until the beginning of the new term that I     2    (开始) to behave well because my English teacher, Miss Yang, a beautiful and attractive lady, kept encouraging me not to give up studying. Under her influence, I was aware of my mistakes and decided to change my     3    (态度) entirely. Every day I     4    (上学) school on time and pay attention to my teachers in class. To     5    (避免) making the same mistakes, I usually attach a note to my desk as a reminder. Knowing that my studies are     6    (糟糕的), I want to improve it badly by making an effort. First, I     7    (醒来) early in the morning to do some reading aloud and attempt to learn the basic knowledge by heart. Also, my teachers are ready to assist me with my studies. With their help, it is not long before I make progress and catch up with my classmates. Not long ago, I participated in an Spoken English Contest on     8    (代表) of my class and I held the firm belief that I would     9    (打败) the other competitors. What astonished everybody was that I attained the championship and was     10    (授予) a gold medal. Now, not only do I go all out to study but I often exercise because only in this way can I keep the balance between study and relaxation.

The hungry bear followed his nose to our camp, which was surrounded by a high wire fence. He pulled and bit the wire. He stood on his back legs and pushed at the wooden fence posts.     1    (恐惧喷薄而出，将我紧紧包围，我已经寸步难行了).     2    (惊恐不已，我觉得两腿发抖，手心冒汗). Beside me was my wife, who was rooted to the ground,     3    (吓呆了). At the sight of the polar bear’ bloody mouth,     4    (吓得要死).The furry creature launched an attack on the fence, instantly leaving a narrow opening on it.     5    (我们感觉浑身血液凝固了)because of the terrible sight. Our throats tightened and our knees felt weak. Elli and I tried all the bear defense actions we knew. We yelled at the bear, hit pots hard, and fired blank shotgun shells into the air.
