Writing out all the invitations by hand was more time-consuing than we             .

will except

are  excepting

except

had excepted

考查時態(tài)。句意：手工寫下所有的邀請函要比我們預(yù)料的花去更多的時間。根據(jù)句意可知我們預(yù)料是在實際上寫之前發(fā)生的，而本句中實際寫花去的時間使用了過去時was，所以expect用過去完成時。故D項正確。

With a lot of difficult problems           ,he feels like a cat on  hot bricks.

to settle

being settled

settling

settled

考查非謂語動詞。句意： 因為有一大堆難題要解決，他感覺像像熱鍋上的螞蟻。本句with +名詞+to do sth,動詞不定式表示的動作尚未發(fā)生或當(dāng)時看來尚未發(fā)生。本句表示“因為有一大堆難題要解決”。故選A項。

Since this accident has nothing to do with him, he seems no way             .

to be blamed

to blame

blame for

to blame for

考查固定用法。句意：既然這次事故與他無關(guān)，他似乎也就無可指責(zé)了。短語sb to be blame“某人該受責(zé)備，某人應(yīng)該負(fù)責(zé)”，為固定搭配，沒有被動語態(tài)。故選B項。

---It's burning hot today,isn't it?

---Yes,_____yesterday.

So was it

So it was

So it is

So is it

句意：“今天太熱了，是不是？”“是呀，昨天也一樣”。如果表示前面所說的肯定情況也適合于另一者，要用“so+助動詞/情態(tài)動詞/系動詞+主語”。

When it comes to modern communication, network safety is always a major          . 

concern

advantage

opportunity

solution

考查名詞辨析。句意：當(dāng)涉及現(xiàn)代通信，網(wǎng)絡(luò)安全一直是一個主要令人擔(dān)憂的問題。A. concern關(guān)心，令人擔(dān)憂的事實或情況；B. advantage 優(yōu)勢；C. opportunity 機(jī)會；D.solution解決方案。網(wǎng)絡(luò)安全一直是現(xiàn)代通信的個主要令人擔(dān)憂的問題。故選A項。
