第一篇
    There are desert plants which survive the dry season in theform of inactive seeds. There are also desert insects which survive as inactivelarvae (幼虫). In addition, difficult as it is tobelieve, there are desert fish which can survive through years of drought (干旱) in the form of inactive eggs. These are the shrimps (小虾) that live in the Mojave Desert, an intensely dry region in thesouth-west of the United States where shade temperatures of over 50C are often recorded.
    The eggs of the Mojave shrimps are the size and have theappearance of grains of sand. When sufficient spring rain falls to form a lake,once every two to five years, these eggs hatch (孵化). Then the wateris soon filled with millions of tiny shrimps about a millimetre long which feedon tiny plant and animal organisms which also grow in the temporary desertlake. Within a week, the shrimps grow from their original 1 millimetre to alength of about 1.5 centimetres.
    Throughout the time that the shrimps are rapidly maturing,the water in the lake equally rapidly evaporates. Therefore, for the shrimps itis a race against time. By the twelfth day, however, when they are about 3centimetre long, hundreds of tiny eggs form on the underbodies of the females.Usually by this time, all that remains of the lake is a large, muddy patch ofwet soil. On the thirteenth day and the next, during the final hours of theirbrief lives, the shrimps lay their eggs in the mud. Then, having ensured thattheir species will survive, the shrimps die as the last of the waterevaporates.
    If sufficient rain falls the next year to form another lake,the eggs hatch, and once again the shrimps pass rapidly through their cycle ofgrowth, adulthood, egg-laying, and death. Some years there is insufficient rainto form a lake: in this case, the eggs will remain dormant for another years,or even longer if necessary. Very, very occasionally, perhaps twice in ahundred years, sufficient rain falls to form a deep lake that lasts a month ormore. In this case, the species passes through two cycles of growth,egg-laying, and death. Thus, on such occasions, the species multipliesconsiderably, which further ensures its survival.

1.Which of the following is the MOSTdistinctive feature of Mojave shrimps?
    A) Their lives are brief.
    B) They feed on plant and animal organisms.
    C) Their eggs can survive years of dought.
    D) They lay their eggs in the mud.
2.By saying "for the shrimps it is a race against time "(Para.3,Line2)the author means_____.
    A) they have to swim fast to avoid danger in the rapidlyevaporating lake
    B) they have to swim fast to catch the animal organisms onwhich they survive
    C) they have to multiply as many as possible within thirteendays
    D) they have to complete their life cycle within a shortspan of time permitted by the environment '
3.The passage mainly deals with_____.
    A) the life span of the Mojave shrimps
    B) the survival of desert shrimps
    C) the importance of water to life
    D) life in the Mojave Desert
4.The word "dormant"(Para.4,Line 3)most probablymeans______.
    A) inactive
    B) strong
    C) alert
    D) soft
5.It may be inferred from the passage that______.
    A) appearance and size are most important for life tosurvive in the desert
    B) a species must be able to multiply quickly in order tosurvive
    C) for some species one life cycle in a year is enough tosurvive the desert drought
    D) some species develop a unique life pattern to survive inextremely harsh conditions

The Welsh language has always been the ultimate marker of Welsh identity, but ageneration ago it looked as if Welsh would go the way of Manx. once widelyspoken on the isle of Man but now extinct. Government financing and centralplanning, however, have helped reverse the decline of Welsh. Road signs andofficial public documents are written in both Welsh and English, andschoolchildren are required to learn both languages. Welsh is now one of themost successful of Europe’s regionallanguages, spoken by more than a half-million of the country’s three millionpeople.
The revival of the language, particularly among young people, is part of aresurgence of national identity sweeping through this small, proud nation. Lastmonth Walesmarked the second anniversary of the opening of the National Assembly, thefirst parliament to be convened here since 1404. The idea behind devolution wasto restore the balance within the union of nations making up the United Kingdom.With most of the people and wealth, England has always had braggingrights. The partial transfer of legislative powers from Westminster,implemented by Tony Blair, was designed to give the other members of the club- Scotland, Northern Ireland, and Wales-a bigger say and to countercentrifugal forces that seemed to threaten the very idea of the union.
The Welsh showed little enthusiasm for devolution. Whereas the Scots votedoverwhelmingly for a parliament, the vote for a Welsh assembly scraped throughby less than one percent on a turnout of less than 25 percent. Its powers wereproportionately limited. The Assembly can decide how money from Westminster or theEuropean Union is spent. It cannot, unlike its counterpart in Edinburgh, enact laws. But now that it ishere, the Welsh are growing to like their Assembly. Many people would like itto have more powers. Its importance as figurehead will grow with the opening in2003, of a new debating chamber, one of many new buildings that aretransforming Cardifffrom a decaying seaport into a Baltimore-style waterfront city. Meanwhile agrant of nearly two million dollars from the European Union will tacklepoverty. Wales is one of thepoorest regions in Western Europe- only Spain,Portugal, and Greece have alower standard of living.
Newspapers and magazines are filled with stories about great Welsh men andwomen, boosting self-esteem. To familiar faces such as Dylan Thomas and RichardBurton have been added new icons such as Catherine Zeta-Jones, the movie star,and Bryn Terfel, the opera singer. Indigenous foods like salt marsh lamb are invogue. And Walesnow boasts a national airline. Awyr Cymru. Cymru, which means “land ofcompatriots,” is the Welsh name for Wales. The red dragon, the nation’ssymbol since the time of King Arthur, is everywhere- on T-shirts, rugby jerseysand even cell phone covers.
“Until very recent times most Welsh people had this feeling of beingsecond-class citizens,” said Dyfan Jones, an 18-year-old student. It was a warmsummer night, and I was sitting on the grass with a group of young people inLlanelli, an industrial town in the south, outside the rock music venue of theNational Eisteddfod, Wales’sannual cultural festival. The disused factory in front of us echoed to thesounds of new Welsh bands.
“There was almost a genetic tendency for lack of confidence,” Dyfan continued.Equally comfortable in his Welshness as in his membership in theEnglish-speaking, global youth culture and the new federal Europe, Dyfan, likethe rest of his generation, is growing up with a sense of possibilityunimaginable ten years ago. “We used to think. We can’t do anything, we’re onlyWelsh. Now I think that’s changing.”

Barbed wire, first patented in the United States in 1867, played an importantpart in the development of American farming, as it enabled the settlers to makeeffective fencing to enclose their land and keep cattle away from their crops.This had a considerable effect on cattle ranching, since the herds no longerhad unrestricted use of the plans for grazing, and the fencing led to conflictbetween the farmers and the cattle ranchers.
Before barbed wire camesintosgeneral use, fencing was often made from serratedwire, which was unsatisfactory because it broke easily when under strain, andcould snap in cold weather due to contraction. The first practical machine forproducing barbed wire was invented in 1874 by an Illinois farmer, and betweenthen and the end of the century about 400 types of barbed wire were devised, ofwhich only about a dozen were ever put to practical use.
Modern barbed wire is made from mild steel high-tensile steel, or aluminum.Mild steel and aluminum barbed wire have two strands twisted together to form acable which is stronger than single-strand wire and less affected bytemperature changes. Single-strand wire, round or oval, is made from high-tensilesteel with the barbs crimped or welded on. The steel wires used are galvanized- coated with zinc to make them rustproof. The two wires that make up the linewire or cable are fed separatelysintosa machine at one end. They leave it atthe other end twisted-together and barbed. The wire to make the barbs isfedsintosthe machine from the sides and cut to length by knives that cutdiagonally through the wire to produce a sharp point. This process continuesautomatically, and the finished barbed wire is wound onto reels, usually madeof wire in length of 400 meters or in weights of up to 50 kilograms.
A variation of barbed wire is also used for military purposes. It isformedsintoslong conies or entanglements called concertina wire.

2.What is the benefit of using two-stranded barbed wire?
(A) Improved rust-resistance
(B) Increased strength
(C) More rapid attachment of barbs
(D) Easier installation.
3.According to the author, the steel wires used to make barbed wire arespecially processed to
(A) protect them against rust
(B) make them more flexible
(C) prevent contraction in cold weather
(D) straighten them.

4.The word“fed" in line 20 is closest in meaning to
(A) put
(B) eaten
(C) bitten
(D) nourished

5.What is the author's purpose in the third paragraph?

第4篇
Without regular supplies of some hormones our capacity to behave would beseriously impaired; without others we would soon die. Tiny amounts of somehormones can modify moods and actions, our inclination to eat or drink, ouraggressiveness or submissiveness, and our reproductive and parental behavior.And hormones do more than influence adult behavior; early in life they help todetermine the development of bodily form and may even determine an individual’sbehavioral capacities. Later in life the changing outputs of some endocrineglands and the body’s changing sensitivity to some hormones are essentialaspects of the phenomena of aging.

Communication within the body and the consequentintegration of behavior were considered the exclusive province of the nervoussystem up to the beginning of the present century. The emergence ofendocrinology as a separate discipline can probably be traced to theexperiments of Bayliss and Starling on the hormone secretion. This substance issecreted from cells in the intestinal walls when food enters the stomach; ittravels through the bloodstream and stimulates the pancreas to liberatepancreatic juice, which aids in digestion. By showing that special cells secretchemical agents that are conveyed by the bloodstream and regulate distanttarget organs or tissues. Bayliss and starling demonstrated that chemicalintegration could occur without participation of the nervous system.

The term “hormone” was first used with reference tosecretion. Starling derived the term from the Greek hormone, meaning “to exciteor set in motion. The term “endocrine” was introduced shortly thereafter“Endocrine” is used to refer to glands that secret products into thebloodstream. The term “endocrine” contrasts with “exocrine”, which is appliedto glands that secret their products though ducts to the site of action.Examples of exocrine glands are the tear glands, the sweat glands, and thepancreas, which secrets pancreatic juice through a duct into the intestine.Exocrine glands are also called duct glands, while endocrine glands are calledductless.

1. What is the author’s main purpose in the passage?
A. To explain the specific functions of varioushormones.
B. To provide general information about hormones.
C. To explain how the term “hormone” evolved.
D. To report on experiments in endocrinology.
2. The passage supports which of the followingconclusions?
A. The human body requires large amounts of mosthormones.
B. Synthetic hormones can replace a person’s naturalsupply of hormones if necessary.
C. The quantity of hormones produced and their effectson the body are related to a person’s age.
D. The short child of tall parents very likely had ahormone deficiency early in life.
3. It can be inferred from the passage that before theBayliss and Starling experiments, most people believed that chemicalintegration occurred only___.
A. during sleep.
B. in the endocrine glands.
C. under control of the nervous system.
D. during strenuous exercise.
4. The word “liberate” could best be replaced by whichof the following?
A. Emancipate
B. Discharge
C. Surrender
D. Save
5. According to the passage another term for exocrineglands is___.
A. duct glands
B. endocrine glands
C. ductless glands
D. intestinal glands.
