【題目】If you start your homework now, you ________ it before dinner.

A.finishB.finishedC.can finishD.have finished

【答案】C

【解析】

句意：如果你現(xiàn)在開始做作業(yè)，你能在晚飯前完成它。

考查動詞時態(tài)辨析。finish 一般現(xiàn)在時；finished 一般過去時；can finish 情態(tài)動詞+動詞原形；have finished 現(xiàn)在完成時。句中if表示“如果”，引導(dǎo)條件狀語從句，且從句是一般現(xiàn)在時，所以主句用一般將來時、或是祈使句或含有情態(tài)動詞的句子。結(jié)合以下四個選項，只有C選項是正確的，所以空格處填can finish。故選C。

【題目】 For the most part of my life, I have lived in a small town in northern Arizona. As I got older, it seemed as if my town got smaller.

All things I could see in the town were bad. It looked ugly, small and was filled with terrible people. I wanted to be in new places with bigger chances and to meet new people. That was exactly what I did. I moved to the city of Phoenix to go to college and worked hard to achieve what I had dreamed of.

For the first year when I was away from home, I wanted to stay away and never go back. When people were taking a trip to my hometown, I would always question “Why would you like to do that? It’s so ugly.” All I had towards my hometown was negative feelings.

However, after being away for about three years, my perspective has completely changed. I have nothing but love for my hometown — its beauty, and the sentimental value (感情價值) that it holds.

After all, it’s where I’m from. Yes, there are bad things, but there are also some good ones: Dad raced the train on the way to school; Mum let us stop for ice cream every Friday after school to celebrate the end of the week; I walked around downtown with friends in high school, thinking we were cool.

It might take being away from something for you to truly appreciate it. It’s true when people say that distance makes the heart grow fonder(溫柔的）. Now I visit my hometown every chance I get. Even if I am no longer living there, it will always hold a piece of my heart.

【1】The writer probably thought his hometown was________from the first three paragraphs.

A.an attractive place for touristsB.filled with friendly people

C.the best place to live inD.a hateful place

【2】What does the underlined word “perspective” in Paragraph 4 probably mean?

A.Dream.B.Opinion.C.Imagination.D.Habit

【3】What’s Paragraph 5 mainly about?

A.How the writer missed his parents.

B.The writer’s sweet memories of his hometown.

C.Unhappy things that happened in the writer’s hometown.

D.Why the writer lost touch with his friends.

【4】What does the last paragraph show?

A.People shouldn’t love their hometown for long.

B.People should leave their hometown.

C.The writer starts loving and valuing his hometown.

D.The writer won’t go back to his hometown.

【題目】 Many of us enjoy watching wild animals. We can learn a lot from them.

Geese(雁）,for example, teach a very god lesson about teamwork. In fall, Canada geese fly to the warm south o get away from cold winter in the north. They lit off in no order. Yet quickly they form a V shape, with one bird leading.

This V shape allows geese to save energy. When the front bird moves its wings up and down, the force(力量）of the air lifts the next one. This continues down the line.

Geese flying in a V shape can fly 70% farther without a rest than birds flying alone.

During the long flying journey, geese communicate with one another. They honk(鳴叫)to encourage the birds to keep up the speed. They also cheer each other up while working towards a common goal.

【題目】根據(jù)短文內(nèi)容，回答下列問題。

No one knows who invented the pencils or when it happened. A Swiss described a pencil in a book in 1565. He said it was a piece of wood with lead (鉛) inside it. Pencils weren’t popular. Then, in 1795, someone started making pencils from graphite (石墨), and they became very popular. Today, people still make pencils in the same way. They put it inside a piece of wood.

One pencil can write 50, 000 English words or make a line 55 kilometers long.

Before the pencils were widely used, people used bird feathers (羽毛) as pens. When people wrote with feather pens, they had to put the point into ink after every few letters. Next, someone invented a fountain pen(自來水筆) that could hold ink inside it. A fountain pen can write a few pages before you have to fill it again.

Two brothers, Ladislao and George Biro, invented the ballpoint pen (圓珠筆) that we all use today. They left their country Hungary (匈牙利) and started making ballpoint pens in England in 1943, during World War II. Later, a French company called Bic bought the Biro brothers’company. Some people call the ballpoint pens “Bics.” Australians call them “biros.” Whatever we call them, we use them every day.

【1】What instruments for writing are mentioned in the passage?

___________________________________________________________

【2】Which was used more often before 1795, pencils or feather pens?

__________________________________________________________

【3】Who invented ballpoint pens?
