weiyu

After refer to the M-W, Longman, Oxford and GRE/GAMT/LSAT CR,RC, I extract almost all kinds of use of "Estimate". Appreciate futher discussion

Estimate总结，请指教fficeffice" />

Verb

Estimate that…

Estimate sth

Estimate for: to calculate the probable cost of doing a job, such as building or repairing sth. Eg. (I asked three building firms to estimate for the repairs to the roof. ) Longman

The projected total of corporate contracts with minority businesses for the early 1980’s is estimated to be over 53 billion per year with no letup anticipated in the next decade. .(GRE/GMAT/LSAT RC,CR)

    

a lizard was recently found that is estimated to be 340 million years old.(GRE/GMAT/LSAT RC,CR)

The value of the painting was estimated at several thousand pounds (Longman Dictionary 被动语态＋at)

The firm estimated the cost of the work at $800 (Oxford)

I estimate his income at/ to be about $5000 (Oxford)

ESTIMATE implies a judgment, considered or casual, that precedes or takes the place of actual measuring or counting or testing out **estimated the crowd at two hundred**.

Summary: 是否可以说estimate to be+时间；estimate at+数量/钱数? 除了牛津的一个例句用了estimate at/to be+钱数，基本都是estimate at+钱数（毕竟Oxford在GMAT准备中应当放在次要位置，非美国字典）

Estimate还可以作名词

Estimated作adj: The movie cost an estimated $25 million to make (Longman)

weiyu,


这里

The projected total of corporate contracts with minority businesses for the early 1980’s is estimated to be over 53 billion per year with no letup anticipated in the next decade. .(GRE/GMAT/LSAT RC,CR)

estimate to be后面加的是金钱呀~~

我的例子应该已经说得很清楚啦？！fficeffice" />


在is estimated句型中，age, cost，price,expenditure等 做主语，用at, to be都行：The cost is estimated at/to be 100$. 注意：可不可以用at关键是看is estimated前面的东东（what is estimated to be/at），或estimate后面的东东(I estmiate what to be/at)。估计任何东东数字的属性，如果estimate 属性（age,cost,price, The price of the gadget is estimated at 10 $.）, 可以用at/to be；如果estimate该东东，即属性的主体（如有该age的人或化石，该price的商品The gadget is estimated to be 10$）则只能用to be. The price of the gadget是The gadget的属性。
