C
A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers． The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season．
Sub - Saharan Africa is the part of the world with the least food security． The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world' s peo-ple faced hunger last year．Around 265 million of them live'south of the Sahara Desert:  Lack of  rainfallis one oftheir main causes offood shortages．．
Jennifer Bumey from Stanford University in Califomia led the study．The research team helped build three solar - powered drip irrigation -（滴灌） ,systems in northem Benin． Between 30 and 35 women used each system to pump water from the ground or a stream．Each woman was responsible for farming her own 120 sqrurre meters of land． They also farmed other land  collectively．
The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb． During the first year, the women．kept a monthly average of almost rune kilograms of vegetables for home use．They sold the surplus produce at local markets． The eamings greatly increased their ability to buy food during the dry season which can last six to nine months． Peo- ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day．But making the surplus available at markets also had a wider effect．
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets． The amount of vegetables eaten in those villages also  increased, though not as much．The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated． Using solar power to pump water has higher costs at first． But    the study says it can be more economical in the long term than using fuels like gasoline,  diesel  or kerosene． And solar power is environmentally friendly．
66．Food security in Sub - Saharan Africa is insufficient mainly because of
A．lack of rainfall         B．limitation of farmland
C． a small crop variety   D．little sunlight
67．From the third paragraph we know that _______．
A．water is wasted by using the system
B． the farmers imgate the land together
C． all farmers use irrigation systems in northem Benin
D． the solar - powered systems take up more manpower
68．The underlined word "surplus" in the 4th paragraph most probably means_______
A．special             B．unnecessary      C．extra      D．abandoned
69．Usinf．solar power to pump water has advantages EXCEPT that
A．solar energy has higher cost at first
B．solar power helps to protect environment
C．solar power helps farmers increase eanungs
D． solar energy can be more economical in the long run
70．What can be the best title for the text?
A．Manpower affects rainfallin Africa
B．Irrigation by carrying water in buckets
C．Solar - powered pumps aid African farmers
D．Vegetable supply increased in African villages

Loch Ness, the largest freshwater lake in the British Isles, is twenty four miles long and, at one point, one mile wide. It has an average depth of four hundred and fifty feet and at times drops close to a thousand. It is cold and murky (混沌的), with dangerous currents. In short, it is the perfect place to hide a monster from even the sharpest eyes of science.
The Loch Ness Monster, also called Nessie, is supposedly living in this area. The earliest recorded sighting of the Loch Ness Monster was in the biography of Life of St. Columba by Adamnan in the year AD 565. The monster apparently attacked a man who was swimming in the River Ness.
The monster didn’t make headlines again until August 27, 1930, when 3 fishermen reported seeing a creature with 20 feet long approaching their boat, throwing water in the air. In 1933, after a new road was built along the edge of the Loch, the number of reports rose suddenly. Early in 1934, Author Grant, a young student, was out on his motorcycle one evening when he almost ran into the monster as it crossed the road. Grant’s description of the thing – small head, long thin neck and tail with a big body, seemed to match the appearance of the plesiosaur (蛇頸龍), an aquatic (水生的) type of dinosaur that has been extinct (已滅絕的) for 65 million years.
The Loch Ness Investigation Bureau was formed in 1962 to act as a research organization for information about the creature. Even now, efforts have continued to find the monster. A great deal of information was discovered about the Loch, but there isn’t any yet to produce any specific evidence of a monster.
Skeptics (懷疑論者) argue that the water in the Loch is too cold for a plesiosaur to live in. They also argue that an air-breathing animal, like a whale or seal, would spend much more time on the surface than the creature seems to, and would be spotted more often.
Some scientists have wondered if the sightings might be caused by an underwater wave which is known to sometimes occur in deep, long, and cold lakes, like Loch Ness. Such a wave might push debris (廢棄物) to the surface that might look like a strange animal.
However, none of these is identified.
【小題1】According to the skeptics, which of the following is TRUE?

A．It is impossible for a monster to live in cold water.
B．The Loch Ness Monster often stays under the water.
C．The Loch Ness Monster is an air-breathing animal.
D．There is no so-called monster in Loch Ness.
【小題2】Which of the following is the correct order for the things that happened in the passage?
a. A young student met with a monster crossing the road.
b. A swimmer was attacked by a monster in Loch Ness.
c. A new road was built along the edge of the Loch.
d. The Loch Ness Investigation Bureau was set up.
e. Three fishermen saw a creature swimming towards their boat.
A．b, e, c, a, dB．a, b, e, d, c
C．b, d, a, c, eD．d, c, e, b, a
【小題3】What does this passage mainly talk about?
A．The natural scenery of Loch Ness.

Each year on the first Saturday in March, a group of middle-aged men and a few women gather at sunrise on a beach near St. Petersburg, Fla. Above the high-water line are more than 50 small boats.

At exactly 7 a.m., Steve Isaac stands at the water’s edge with his arm raised and yells: “Go!”

Most of the boats are part of the Everglades Challenge. They head for a finish line many days and 300 miles to the south, at Key Largo. But this Saturday, for the first time, 10 of the brave mariners―including a journalist, whose progress will be available online―will compete in the world’s toughest small boat race, called the Ultimate Florida Challenge.

Instead of finishing at Key Largo, the 10 boaters will continue around the state, heading north past Miami, the Kennedy Space Center, and Jacksonville, then down the Suwannee River, eventually passing most of Florida before arriving back at the beach near St. Petersburg.

It will be 1,200 miles of head winds and burning sun. But it will also take the challengers through some of the most impressive scenery in North America.

The rules are no-nonsense: First one back to the beach wins. The voyage must be completed within a month. Human power or sails, only. No motors. No rides in cars or tows from power boats. No help from family or friends. And at least once a day, participants are required to acknowledge by cell phone or radio that they are still alive.

The race will be a replay of the tale of the tortoise (龜) and the rabbit. The trick, if there is one, is to be a tortoise and just keep moving forward. But the one-month deadline means that being too much of a tortoise may result in failure. So challengers have to be a little bit of a rabbit, as well.

 

72. What can we infer from the passage?

   A. People can watch the 1200-mile race on the net this year.

   B. Over 50 boats will take part in the 300-mile race this year.

   C. The racers cannot take a rest during the race.

   D. The winner will act as a tortoise in the play. 

73. This 1,200-mile race is unusual because _____.

   A. more people will take part                B. only men will take part

   C. its rules are meaningless                   D. it will be more challenging

74. According to the last paragraph, _____ is most important if one wants to win the race.

   A. strength                     B. courage                    C. equipment                D. strategy

75. Which can be the best title for the passage?

   A. Around the coast in 30 days                            B. Among the life-and-death tests

   C. A new world record expected                   D. Everglades Challenge on line
