12.If we use the new recycling method,a large number of trees          .(  )
A.are savedB.will saveC.will be savedD.have saved

分析 如果我們使用這種新型的循環(huán)利用的方式,那么大量的樹木將被拯救.

解答 答案:C.
從句用一般現(xiàn)在時代替的是將來時態(tài),主句用一般將來時,可排除A和D;再根據(jù)trees和save兩者之間為邏輯上的動賓關(guān)系,即樹是被拯救,所以用被動,可排除B.故選C.

點(diǎn)評 本題考查了一般將來時態(tài)的被動語態(tài);做此類題時,可以根據(jù)句中的時間狀語確定該句應(yīng)使用的時態(tài);然后結(jié)合句意,通過判斷主語與為謂語動詞的關(guān)系,確定它的語態(tài)(當(dāng)主語與謂語動詞構(gòu)成動賓/被動關(guān)系時,應(yīng)使用被動語態(tài)).

4.When my friends went to college in great delight,I restarted my senior high school life.My spirit sank.Surrounded by strange classmates,I felt like I was in a maze and was sorry about myself.There were some complex feelings in my minds.I was frightened,nervous and lonely.
To make matters worse,I recalled my failure again and again,which put more pressure on me than I could bear.As a result,I was always feeling down during class time.
My teacher found me spiritless.One day he asked me to come to his office and told me about his attitude towards life:we might suffer from mistakes,but it's important to learn lessons from them.All the pains and the embarrassing things we experience are part of the process.So keep up your spirit!At last,he added,"If you are optimistic,things you want may happen to you!"
Warmth rushed through my soul.I suddenly found the sun shining again when I stepped out of his office.
With the teacher's help,I eventually got over my depression.From then on,I no longer bowed my head and began smiling to my classmates.I would put up my hand confidently in class and play with my new friends in my spare time.Meanwhile,I was gradually embraced by my classmates.
Now faced with fierce competition,we all study hard because we know that every second counts.Moreover,there is an atmosphere of mutual trust and respect between us.I love my class; I love my classmates!
To be frank,I still have a thirst for my dream university,but I'm not afraid of failure because I can profit by it.With parents and teachers'encouragement,I'm quite certain of my success and I'm sure I can fly high.

56.Why was the writer in low spirits at the beginning?(No more than 10words)

57.What did the teacher expect the writer to do?(No more than 10words)

58.What is the main idea of Paragraph 5?(No more than 15words)
With the teacher's help,he eventually got over his depression.
59.The underlined word"embraced"in paragraph 5means.(No more than 5words)Accepted/Welcomed.
