【題目】The students of our class _____ to swim last month and we can swim very well now.

A. taught B. had taught

C. was taught D. were taught

【答案】D

【解析】試題分析：句意：我們班里的學(xué)生上個(gè)月都學(xué)游泳了，我們現(xiàn)在游的非常好。主語學(xué)生和謂語動(dòng)詞teach之間是被動(dòng)關(guān)系，所以用被動(dòng)結(jié)構(gòu)：be +done.根據(jù)動(dòng)作發(fā)生的時(shí)間是last month，可知用過去時(shí)態(tài)，主語是復(fù)數(shù)，故選D。

【題目】根據(jù)材料內(nèi)容選擇最佳答案，并將其標(biāo)號(hào)填入題前括號(hào)內(nèi)。
Have you ever had trouble sleeping in a new place?

Lots of people do. And now researchers from Brown University in Rhode Island think they know why. They found that one-half of the brain "remains more awake" than the other half when people are trying to sleep in a new place.
The sleep findings were reported in Current Biology by Brown University. In their report, the researchers said many people report they have a harder time sleeping the first night at a hotel or other places outside their home. They call it "first-night influence". "In Japan they say, 'If you change your bed, you can't sleep,'" said Yuka Sasaki, one of the report's writers. "You don't sleep very well in a new place. We all know about it."
The researchers measured brain waves (測(cè)量腦波) for 35 volunteers over two nights in a laboratory. The two nights were a week apart (間隔). They found during the first night the left half of the brain was more active than the right half. This was during the first deep-sleep period, the researchers said.
Sasaki said a lot of questions remain.
Researchers did not keep measuring brain waves all night long. So, they don't know if the left half keeps "watch" all night, or whether it "works in shifts (輪換) with the right half later in the night". They also do not know why the brain activity, at least during the first period of deep sleep, is always on the left half.
For some, this research may be calming. It is good to know that our brain is "looking out for us" in a new place. But it may not help with sleep. That brain activity, at least according to this new research, makes it harder to get the sleep people need to wake up well rested in the morning.
（1）How many times did the researchers measure brain waves for 35 volunteers?
A.Once.
B.Twice.
C.Three times.
D.Four times.
（2）The researchers found during the first deep-sleep period.
A.the brain waves remained the same
B.the brain activity helped with sleep
C.the right half of the brain kept "watch"
D.the left half of the brain was more active
（3）Which of the following is one of the questions that remain?
A.Whether the new bed keeps you from sleeping.
B.How you have trouble sleeping in a new place.
C.Why the brain activity is always on the left half.
D.What people can do when they can't sleep well.
（4）The underlined word "calming" has the closest meaning to" ".
A.pleasing
B.different
C.serious
D.strange
（5）What is the text mainly about?
A.What we will have to do to sleep well.
B.How researchers measure brain waves.
C.Who doesn't sleep well in a new place.
D.Why it's harder to sleep in a new place.
