A．WhatB．WhichC．ThatD．Who

分析 這些語言中大多數(shù)現(xiàn)在正受到危險，也許會消失，這對英國人來說是件嚴重的事．

解答 答案：C 題干中most of these languages are now threatened and may disappear是充當(dāng)is的主語，是一個主語從句；從句結(jié)構(gòu)完整，不缺少成分，要用that來引導(dǎo)，并且不能省略．故選C．

點評 主語從句是名詞性從句的一種，在句中作主語，相當(dāng)于一個名詞．連接詞要根據(jù)從句的結(jié)構(gòu)來判定，從句結(jié)構(gòu)完整時，要用連接副詞或that；從句缺少主語或賓語時，要用連接代詞．

More students than ever before are taking a gap year(間隔年) before going to university. It used to be the “year off” between school and university. The gap-year phenomenon originated(起源) with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.

This year, 25,310 students who have accepted places in higher education institutions have put off their entry until next year, according to statistics on university entrance provided by the University and College Admissions Service (UCAS).

That is a record 14.7% increase in the number of students taking a gap year. Tony Higgins from UCAS said that the statistics are good news for everyone in higher education. “Students who take a well-planned year out are more likely to be satisfied with, and complete, their chosen course. Students who take a gap year are often more mature and responsible,” he said.

But not everyone is happy. Owain James, the president of the National Union of Students (NUS), argued that the increase is evidence of student hardship – young people are being forced into earning money before finishing their education. “New students are now aware that they are likely to leave university up to￡15,000 in debt. It is not surprising that more and more students are taking a gap year to earn money to support their study for the degree. NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacating periods,” he said.

1.What do we learn about the gap year from the text?

A. It is flexible in length.

B. It is a time for relaxation

C. It is increasingly popular

D. It is required by universities

2.According to Tony Higgins, students taking a gap year ____.

A. are better prepared for college studies

B. know a lot more about their future job

C. are more likely to leave university in debt

D. have a better chance to enter top universities

3.How does Owain James feel about the gap-year phenomenon?

A. He’s puzzled B. He’s worried

C. He’s surprised D. He’s annoyed

4.What would most students do on their vacation according to NUS statistics?

A. Attend additional courses.

B. Make plans for the new term

C. Earn money for their education

D. Prepare for their graduate studies

17．They tell us when to get up or when we're running late for work and whether we are in danger of missing our favourite TV programme．But while our daily routines rely on clocks that tell us the time，science is discovering that our well-being is influenced by a very different kind of timepiece．Circadian rhythms（生理節(jié)奏）-the human body's own internal clock-have a powerful influence on our health and behaviour． They are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns．
In recent years researchers have also discovered that this built-in mechanism（機能）can influence everything from the way we react to medicines to how well we learn music．
The latest example，from experts at Harvard University in the US，shows that the human body clock can even tell whether or not we are likely to tell the truth．Researchers found it was easier for people to lie in the afternoon because，as they were tired，the self control that would normally prevent them from lying started to break down．Tiredness made it harder to resist the temptation to tell lies-especially if it meant they got a financial reward at the end．
"The body clock has a great effect on us all，"says Professor Jim Horne from the Sleep Research Centre at Loughborough University．"Most people tend to feel good around late morning and then decline in the early afternoon．But the time most of us will feel our sharpest is between 6pm and 8pm．That's because sleepiness tends to build up throughout the day．By early evening our body clock kicks in to wake us up．One reason may be to ensure we get home safely．When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece．"
So what effects do circadian rhythms have and what's the best time of day to take advantage of them？
66．The underlined word"They"in the first paragraph refers toD．
A．our clocks
B．scientists and experts
C．our daily routines
D．circadian rhythms
67．The research referred to in Paragraph 3found that people tend toA．
A．tell lies when they are tired
B．tell lies if they are rewarded
C．lose temper as they become tired
D．break down because they are tired
68．According to the passage，when are people most quick-thinking？D
A．In the morning．
B．Around midday．
C．In the late afternoon．
D．In the early evening．
69．What information will the writer probably present following the last paragraph？C
A．Some practical suggestions to prevent people from lying．
B．Examples of how the human body clocks control the body．
C．Examples of the most suitable time to do different activities．
D．An explanation of how the human body clock controls the body．
70．What is the best title for the passage？B
A．Rebuild Your Body Clock．
B．Timing Is Everything．
C．Sleep More，Lie Less．
D．Your Time Is Up．

7．What do you remember about your childhoods I have good memories？of exploring the fields near my house and riding my bike around the park．Today，children don't spend enough time in the fresh air．Many of them fix their eyes on a screen either on a computer，or a TV-they seem to be living in a virtual world．They have lost touch with nature．
Now 400 organizations in the UK are encouraging children to have some"wild time"．They want kids to exchange at least 30minutes of watching TV or playing computer games for time playing outside．The simple pleasures of exploring and discovering nature help children to learn and keep fit too．Andy Simpson，who is part of the campaign，says："An extra 30minutes of wild time every day for all under 12-year-olds in the UK would be the equivalent（同等） of just three months of their childhood spent outdoors．"Even if the kids live in a city，they can go on adventures in the garden or the park．However，children often need a helping hand from Mum and Dad．They need to be shown what to do and where to go．
So despite the complex world that young people grow up in now，it seems that going back to basics and experiencing"nature's playground"is what modern children need．Andy Simpson adds："We want parents to see what this magical wonder product does for their kids'development，independence and creativity，by giving wild time a go"．David Bond from Project Wild Thing says"we need to make more space for wild time in children's daily routine，freeing this generation of kids to have the sort of experiences that many of us took for granted"．

24．What does the author think about the present kids？B
A．They depend on their parents too much
B．They don't get close to nature．
C．They spend too much time playing outside．
D．They're eager to play with their parents．
25．In the last paragraph"wonder product"probably refers toA．
A．nature's playground 
B．helping hand
C．daily routine 
D．complex world
26．What suggestion does David Bond give us？D
A．Prevent kids from playing computer games．
B．Help children master basic skills．
C．Teach kids how to face difficulties．
D．Let children have more wild time．
27．What do we know about the author？C
A．He disliked his childhood full of study and exams．
B．He often went to school by riding on a bicycle．
C．He had a happy childhood by exploring the outdoors．
D．He showed a great interest in watching TV．
