15．Is this dictionary ______ you looked for just now？（　　）
A．thatB．the oneC．whichD．what

分析 這本字典是剛剛你在找的那本嗎？

解答 答案：B，考查表語從句的用法，分析句子成分，主語this dictionary，后接be動詞is，因此空格處作表語，只能使用the one，并且the one作為先行詞，在定語從句中 you looked for just now做賓語，引導詞可省略，故答案為B．

點評 考查表語從句的用法，注意分析句子成分，進而對答案進行確定．

11．Children have their own rules in playing games．They seldom need a referee and rarely trouble to keep scores．They don't care much about who wins or loses，and it doesn't seem to worry them if the game is not finished．Yet，they like games that depend a lot on luck，so that their personal abilities cannot be directly compared．They also enjoy games that move in stages，in which each stage，the choosing of leaders，the picking-up of sides，or the determining of which side shall start，is almost a game in itself．
Grown-ups can hardly find children's games exciting，and they often feel puzzled at why their kids play such simple games again and again．However，it is found that a child plays games for very important reasons．He can be a good player without having to think whether he is a popular person，and he can find himself being a useful partner to someone of whom he is ordinarily afraid．He becomes a leader when it comes to his turn．He can be confident，too，in particular games，that it is his place to give orders，to pretend to be dead，to throw a ball actually at someone，or to kiss someone he has caught．
It appears to us that when children play a game they imagine a situation under their control．Everyone knows the rules，and more importantly，everyone plays according to the rules．Those rules may be childish，but they make sure that every child has a chance to win．

24．What is true about children when they play games？A
A．They don't need rules．
B．They want to pick a better team．
C．They can test their personal abilities．
D．They can stop playing any time they like．
25．To become a leader in a game the child has toB．
A．play well
B．wait for his turn
C．be confident in himself
D．be popular among his playmates
26．The writer believes thatA．
A．children play games without reasons
B．children's games can do them a lot of good
C．children should invite grown-ups to play with them
D．children should make better rules for their games．

12．Every day，people come into contact with thousands of chemicals．These chemicals are said to be harmless to human health．In fact，the chemicals are considered so safe that we wash with them．We put them on our bodies and even our faces．Other chemical products are used throughout our homes．
By the time you walk out of your front door，you have already been exposed to thousands of chemicals．
On its own，each chemical seems harmless．But in combination with other chemicals，they may become deadly．That is the finding of a two-year study by a high-profile（高調的）task force of scientists．The task force was told to investigate the cancer-causing possibility of chemical mixtures．
Linda Gulliver was one of the 174 scientists on the task force．Their job was to study the cancer-causing potential of 85 chemicals．All 85 are said to be common in the environment．
Ms．Gulliver explains that chemicals have the potential or ability to form dangerous mixtures．Even simple minerals can become dangerous when mixed with chemicals found in plastics or beauty products．
Working in groups，the scientists explored how different chemical mixtures could lead to cancer．Ms．Gulliver's team looked at the ability of different combinations to support the increase of malignant（惡性的）human cells．
She says the current way to identify whether chemicals cause cancer is to test them one at a time．This method leads，she adds，to a long list of supposedly"safe"chemicals．She and her team say that approach needs to change．
"We definitely need certain research…to find out what mixtures of chemicals would be more harmful than others； what groups of chemicals，when together，would produce more harmful effects．And at the moment，that is not known．"
An estimated one in five cancers has been linked to chemical exposure．It may turn out that the cancer-causing villain（惡棍）is not a single chemical at all．

32．What effect may one single chemical have on us according to the text？B
A．It may destroy our body．
B．It may not cause danger to us．
C．It may let us suffer from cancer．
D．It may let our body make a change．
33．What can we learn about Ms．Gulliver's research？D
A．She has found 85 cancer-causing chemicals．
B．She has found reasons for five kinds of cancers．
C．She has found that only one chemical can cause cancer．
D．She is not sure what mixtures of chemicals are more harmful．
34．According to the text，we can infer that the studyB．
A．is just wasting time and money
B．is still in need of great efforts
C．will cause panic in public
D．will be resisted by the public
35．What is the best title for the text？A
A．Mixtures of Safe Chemicals May Cause Cancer
B．Being Exposed to One Chemicals Is Dangerous
C．How Mixtures of Safe Chemicals Come into Being？
D．What Is the Real Cause For Cancer？
