水热配合好 昼夜温差大 光照充足 劳动力丰富

A.①② B.③④ C.①③ D.②③

【答案】

【1】D

【2】D

【解析】

试题分析:

【1】表格中人力效率指每劳动日的粮食产量,其数值大小反映出劳动生产率的高低,人力效率越高,劳动生产率越高,因此东北和新疆劳动生产量最高,这主要是因为这两个地区地广人稀,农业生产的机械化水平较高,因此劳动生产率最高。

【2】从表中可以看出,自然资源效率最低的地区是西北省份,而最高的地区是东南省份,西北省份深居内陆,降水稀少,多晴天,因此具有光照充足、昼夜温差大的优势;而东南省份以季风气候为主,水热配合好是其显著优势。

How To Write A Proper “Thank You” Email

In our daily life, it’s important that you know how to write a proper, and professional thank you email.

Use the correct name.

Whoever the person you are writing the email to is, you want to make sure you thank them by showing them your paying enough attention to know their name. While the difference between Dr. and Mr. or Joe and Joan, may be a couple letters, they’ll notice. 【1】

Explain who you are.

You know who you are, and you know why you are writing the letter, but don’t leave the recipient(收件人) trying to figure out who the email is from until the end. 2 And also remind them what they did for you.

Always use the subject line.

Never accept that little message that turns up when you try to send an email without a subject line. 3 An email without a subject line is either going to get overlooked or deleted.

4

An email with spelling or grammar mistakes shows that you didn’t care about the email enough to give it the time to be corrected.

Use a signature.

Even if it just a simple thank you email, you always want your name to appear. Use a signature to stand out. 5 Use bold text for your signature or a slightly different font to stand out from the rest of the generic email.

A. Correct it.

B. But to do that you have to have a span>name.

C. You want to look professional in all your emails.

D. Teachers or professors get hundreds of emails a day.

E. Take the first couple sentences to reintroduce yourself.

F. Under your name write where you’re from, your class year.

G. Make sure you check the spelling of a name before you hit send.
