Question: Article: Terry Thomas has a very boring job ,although it pays very well .What Terry does is sitting in a rowboat all day long .He makes $ 16.37 an hour ,which is certainly an excellent wage for sitting in a little boat and doing nothing. The boat stays all day under a bridge that is being rebuilt. There is a distance of about 100 feet between the boat and the workers on the bridge overhead. The rest of Terry's fellow workers are up on the bridge working. Terry's job is to rescue anyone who falls off the bridge into the water. So far, no one has given him anything to do .Although he's delighted that none of his companions has fallen into the water, he also admits that the job is very boring because there is nothing to do. No one on the work crew really wants duty on the boat. But the job is a union requirement, and it must be filled. To quality for the job, a person must be an excellent swimmer and have training in lifesaving skills. Only a few men on the work crew meet those standards. Before Terry took the boat job, several others had it and gave up because they found it so tedious.  What does Terry do in his little boat all day? He spends a good bit of time making sure that his suntan lotion is adequate for the job of protecting his skin. He reads and listens to the radio .Each day he looks forward to lunch and then to quitting time. 
 Question: What's the best title for the passage? 
 Options: (A) A Boring Job (B) The Man in a Rowboat (C) A Job of Great Skill (D) Hard Physical Labor 
 Asnwer: A

Answer: Yes


Question: Article: Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery   that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions   are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode   made of many carbon-based graphene   sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters   of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered   by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week.  "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available within five years, the researchers said. 
 Question: What is the major problem of current rechargeable batteries? 
 Options: (A) They are not very stable. (B) They cannot hold enough silicon. (C) They have limited energy capacity. (D) The space between the graphene sheets is too big. 
 Asnwer: A

Answer: No


Question: Article: Certainly no creature in the sea is stranger than the common sea cucumber . All living creatures, especially human beings, have their features, but everything about the little sea cucumber seems unusual. What else can be said about an unusual animal that eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered eatable? For some fifty million years, in spite of all its strange features, the sea cucumber has lived on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of color1s, ranging from black to reddish-brown to sand-color1 and nearly white. One form even has brilliant purple tentacles . Usually the creature are cucumber-shaped--where their name comes from--and because they live in rocks, this shape, combined with flexibility, enables them to press into crevices  where they are safe from animal eater and ocean currents. Although they have greedy desire for food, eating day and night, sea cucumbers have the ability to become still and live at a low metabolic  rate--feeding a little or not at all for long periods, so that the living things in the ocean that provide their food have a chance to increase by a large amount. If it were not for this natural ability, they would swallow all the food available in a short time and would probably starve themselves out of existence. But the most impressive thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it forces all its internal organs in its body out into water. It also removes attached structures such as tentacles. The sea cucumber will get rid of its organs and grow itself again if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted. 
 Question: According to the passage, why is the shape of sea cucumbers important? 
 Options: (A) It helps them to protect themselves from danger. (B) It makes it easier for them to move through the mud. (C) It makes them attractive to fish. (D) It helps them to digest their food. 
 Asnwer: C

Answer:
No
