1．Ho Khanh is a middle-aged farmer，living in a village on the edge of Phong-Nha-Ke Bang National Park in Vietnam．What is special about him is that he has discovered Son Doong，the largest cave in the world．
"I first found the cave more than twenty years ago，in 1991，"he says．"I was out collecting firewood near the national park．My family were very poor，so I decided to go deeper into the forest to find some aloe （芦荟），which is very valuable．Not many people went that far into the forest because they were afraid of the wild animals．"
Soon Khanh lost his way．"I sat down with my back to a huge round rock，"he says．"Then I heard the sound of a strong wind and running water coming from behind me．"He found the entrance to a huge cave，with a wide river coming out of it．Khanh thought he was walking into a great cave．With no ropes or lights，he did not go further into it．
Khanh's story spread like wildfire，but not everyone believed him．"I wanted to prove that I was telling the truth，but I couldn't remember the way to the cave．"Then one morning early in the winter of 2006，a group of cavers from Britain came to ask Khanh for help，as they had heard about his discovery fifteen years before．
Khanh agreed to help the team to find the cave，but after three days in the jungle （丛林），they lost their way．"I just couldn't remember where it was，"he says．The team came back twice，but each time they were beaten by the thick jungle．Finally the cavers left．
In 2009，Khanh headed to the jungle one cold winter's morning．"I stopped by a big round rock，"he says．"There was the same strong wind，the sound of water running----I knew I'd found the cave at last．"Soon the British cavers returned and followed Khanh on a six-hour trip deep into the jungle．On April 14they found Son Doong．

4．How did Khanh discover Son Doong？A
A．By accident completely．
B．By following wild animals．
C．Through ropes and lights．
D．With the help of British cavers．
5．How long did it take Khanh to prove he discovered Son Doong？C
A．About three years．
B．About fifteen years．
C．About eighteen years．
D．About twenty years．
6．What did the British cavers think of Khanh's story？B
A．Doubtful．          B．Reliable．
C．False．             D．Ridiculous．
7．It can be inferred from the passage thatC．
A．there is little water in the Son Doong
B．there is a lot of aloe in Son Doong
C．there is a huge rock at the entrance to Son Doong
D．there is the largest national park near Son Doong．
2．Measles（麻疹），which once killed 450 children each year and disabled even more，was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine（疫苗）．But the disease is making a comeback，caused by a growing anti-vaccine movement and misinformation that is spreading quickly．Already this year，115 measles cases have been reported in the USA，compared with 189 for all of last year．
     The numbers might sound small，but they are the leading edge of a dangerous trend．When vaccination rates are very high，as they still are in the nation as a whole，everyone is protected．This is called"herd immunity"，which protects the people who get hurt easily，including those who can't be vaccinated for medical reasons，babies too young to get vaccinated and people on whom the vaccine doesn't work．
     But herd immunity works only when nearly the whole herd joins in．When some refuse vaccination and seek a free ride，immunity breaks down and everyone is in even bigger danger．
     That's exactly what is happening in small neighborhoods around the country from Orange County，California，where 22 measles cases were reported this month，to Brooklyn，N．Y．，where a 17-year-old caused an outbreak last year．
     The resistance to vaccine has continued for decades，and it is driven by a real but very small risk．Those who refuse to take that risk selfishly make others suffer．
     Making things worse are state laws that make it too easy to opt out（决定不参加） of what are supposed to be required vaccines for all children entering kindergarten．Seventeen states allow parents to get an exemption（豁免），sometimes just by signing a paper saying they personally object to a vaccine．
     Now，several states are moving to tighten laws by adding new regulations for opting out．But no one does enough to limit exemptions．
     Parents ought to be able to opt out only for limited medical or religious reasons．But personal opinions？Not good enough．Everyone enjoys the life-saving benefits vaccines provide，but they'll exist only as long as everyone shares in the risks．

63．The first two paragraphs suggest thatA．
A．a small number of measles cases can start a dangerous trend
B．the outbreak of measles attracts the public attention
C．anti-vaccine movement has its medical reasons
D．information about measles spreads quickly
64．Herd immunity works well whenC．
A．exemptions are allowed
B．several vaccines are used together
C．the whole neighborhood is involved in
D．new regulations are added to the state laws
65．What is the main reason for the comeback of measles？D
A．The overuse of vaccine．
B．The lack of medical care．
C．The features of measles itself．
D．The vaccine opt-outs of some people．
66．What is the purpose of the passage？C
A．To introduce the idea of exemption．
B．To discuss methods to cure measles．
C．To stress the importance of vaccination．
D．To appeal for equal rights in medical treatment．

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(氢) 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 65 cities 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.

1.What do we know about the hydrogen isotopes according to Paragraph 3?

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.

2.Why is it possible to know where people are from by analyzing their hair?

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’s hair indicates the type of water in the places they stay.

3.The last paragraph is mainly to show _______.

A. how to recognize criminals B. how to collect hair samples

C. the usefulness of hair analysis D. the process of Ehleringer’s study

4.Which of the following can be the best title for the passage?

A. Water composition B. Change your hair

C. Hair detectives D. No way out
18．He______his engagement just before the wedding．（　　）
