8.It is only when each logical step has been checked by other mathematicians _________.(  )
A.the proof will be accepted
B.will the proof be accepted
C.that will the proof be accepted
D.that the proof will be accepted

分析 只有当每一个逻辑步骤被其他数学家检查过,证据才会被接受.

解答 C 考查强调句.only when each logical step has been checked by other mathematicians 时间状语从句,是被强调部分,the proof will be accepted 强调句部分使用陈述语序,所以答案选C.

点评 强调句是英语中的一个基本句型,也是考试的一个语法内容,在英文中,句子的主语、宾语、状语都可以以一种固定的句式表示对它的强调.It is/was+被强调部分+that+句子的剩余部分,掌握固定结构是做好强调句的关键.

16.Cleverness is a gift while kindness is a choice.Gifts are easy-they're given after a11.Choice can be hard.
I got the idea to start Amazon 16years ago.I came across the fact that the Internet usage was growing at 2300percent per year.I'd never seen or heard of anything that grew that fast,and the idea of building an online bookstore with millions of titles was very exciting to me.I had just turned 30years old,and I'd been married for a year.I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't and I wasn't sure what to expect.MacKenzie told me I should go for it.As a young boy,I'd been a garage inventor.I'd always wanted to be an inventor,and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people and I had a brilliant boss that I much admired.I went to my boss and told him I wanted to start a company selling books on the Internet.He took me on a long walk in Central Park,listened carefully to me,and finally said,"That sounds like a really good idea,but it would be an even better idea for someone who didn't already have a good job."That 1ogic made some sense to me,and he convince me to think about it for 48hours before making a final decision.Seen in that light,it really was a difficult choice,but finally,I decided I had to give it a shot.I didn't think I'd regret trying and failing.And I suspected I would always be haunted by a decision not to try at all.
After much consideration,I took the less safe path to follow my passion,and I'm proud of that choice.For all of us,in the end,we are our choices.

17.Each morning Grandpa was up early sitting at the kitchen table,reading his book.His grandson wanted to be just like him and tried to copy him in every way he could.
One day the grandson asked,"Grandpa,I try to read the book just like you,but I don't understand it,and I forget what I understand as soon as I close the book.What good does reading the book do?"
The grandpa quietly turned from putting coal in the stove and replied,"Take this coal basket down to the river and bring me back a basket of water."
The boy did as he was told,but all the water leaked out before he got back to the house.The grandpa laughed and said,"You'll have to move a little faster next time,"and sent him back to the river with the basket to try again.
This time the boy ran faster,but again the basket was empty before he returned.Out of breath,he told his grandpa that it was impossible to carry water in a basket,so he went to get a bucket instead.
The grandpa said,"I don't want a bucket of water; I want a basket of water.You're just not trying hard enough."
The boy again dipped the basket into the river and ran hard,but when he reached his grandpa the basket was empty again.Out of breath,he said,"Grandpa,it's useless!"
"So,you think it is useless?"the grandpa said,"Look at the basket."
The boy looked at the basket and for the first time he realized that the basket was different.It had been transformed from a dirty old coal basket and was now clean.
"Grandson,that's what happens when you read the book.You might not understand or remember everything,but when you read it,you'll be changed,inside and out."

21.What puzzled the grandson most wasB.

B.To punish him for not reading carefully.
C.To clean the dirty basket in the river.

    If you want to join the ranks of gorillas next September,you only have to pay£60 to register.This includes the gorilla suit,which you can keep.If you take part,not only will you have been helping the gorillas and people who depend on their habitat,you'll never have to buy another set of fancy clothes again!
