5.-It _____be John who is in the office.
-No,it ____be him.I saw him off at the airport half an hour ago.( 。
A.can't; can'tB.must; can'tC.must; mustn'tD.may; mustn't

分析 --辦公室里一定是John.
--不,不可能是他.半個小時之前我在機場目送他離開的.

解答 答案:B
解析:根據(jù)答句后面的"半個小時之前我在機場目送他離開的"可知回答者的意思是"不可能"是John,故C、D選項直接排除(mustn't意為"禁止");由此反推上一句的句意為"辦公室里一定是John",故A選項(can't不可能)排除(如果選擇A則上下句子互相矛盾).綜上,本題答案為B選項.

點評 本題考查情態(tài)動詞的辨析,做此類題題目時一定要清楚各個選項的含義及用法,再結(jié)合選項分析及其它要求選出最終答案.

"We may look(65)different(difference)on the outside,but we're all the same,"I would tell the visitors."Just because a horse or a goat (66)has(have) four legs instead of two doesn't mean they don't have needs and wants and a voice.We just have to learn how (67)to hear(hear) their voice and how to understand their (68)desires(desire).If we walk into their space (69)slowly(slow),quietly,we show our gentle,respectful intent,and hopefully that animal will pay back by (70)allowing(allow) us to be with them and to pet them.But if they don't we need to respect that,too."

6.You can tell a lot about people by looking at their hair-not just whether they brush,spray or blow-dry.Scientists have found a way to use hair to figure out where a person is from and where that person has been.The finding could help solve crimes,among other useful applications.
Water is central to the new technique.The liquid makes up more than half an adult human's body weight.Our bodies break water down into hydrogen(氫) and oxygen.Atoms of these two elements end up in our tissues,fingernails,and hair.
But not all water is the same.Hydrogen and oxygen atoms can vary in how much they weigh.In the case of hydrogen,for example,there are three types according to their weights.Each type is called a hydrogen isotope(同位素).And depending on where you live,tap water contains different isotopes.
Can hair record this information?That's what James R.Ehleringer,an environmental chemist at the University of Utah,wondered.To find it out,he and his colleagues collected hair from hair stylists in 65cities across the United States.Even though people drink a lot of bottled water these days,the researchers have found that people's hair has the same isotopes as found in local tap water.That's probably because people usually cook their food with the local water.
Authorities can now use the information to analyze hair samples from criminals or crime victims and narrow their search for clues.For example,one hair sample used in Ehleringer's study came from a man who had moved from San Francisco to Salt Lake City.As his hair grew,it reflected his change in location.

28.What do we know about the hydrogen isotopes according to Paragraph 3?B
A.They are classified by size.
B.Each type of them differs in weight.
C.They can improve the quality of tap water.
D.Some of them cannot combine with oxygen.
29.Why is it possible to know where people are from by analyzing their hair?D
A.People use the same bottled water.
B.People wash their hair in different ways.
C.People's hair is affected by the weather of the places they stay.
D.People'hair indicates the type of water in the places they stay.
30.The last paragraph is mainly to showC.
A.how to recognize criminals
B.how to collect hair samples
C.the usefulness of hair analysis
D.the process of Ehleringer's study
31.Which of the following can be the best title for the passage?C
A.Water composition    B.Change your hair     C.Hair detectives D.No way out.
