From babies to body builders, we all have muscles. They grow, they bulge(鼓起), they stretch they stretch and sometimes they even painfully pull. But for all the work they do for us, we are still unable to crown one as "the strongest muscle."
Instead, a few muscles could claim the title, depending on how strength is measured.
If the title goes to the muscle that can exert(產(chǎn)生) the most force, the victor would be the soleus（小腿肚�。�, according to Gray's Anatomy（解剖學(xué)）. Without this muscle, we wouldn't be able to stand, walk, run or shake our bodies on the dance floor. If the soleus was not continuously pulling, we would always be falling over ourselves (although some of us tend to do that from time to time anyway).
But perhaps the title should go to the muscle that exerts the most pressure. Pressure is different from force — pressure takes into account the area over which a force is exerted. The muscle that takes the prize for delivering the greatest amount of pressure is the masseter, or the jaw muscle, according to the book "Clinical Oral Science" (Reed Educational and Professional Publishing, 1998).
In 1986, Richard Hofmann of Lake City, Fla., achieved a bite strength of 975 pounds (442 kilograms) for two seconds, setting a Guinness Record. Talk about jaw dropping! The jaw is able to clench（咬緊） and chew because of the masseter muscle.
Others may argue the muscles used in childbirth are the most powerful.
When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity（伸縮性） and forcefulness gives us the ability to speak, eat and kiss – all things very desirable on a first date. However dexterous（靈巧的） it may be though, its power does not match that of muscles such as the soleus.
If slow and steady wins the race, the heart is certainly a contender for the title. When it contracts, the muscle pumps about 2 ounces (59 milliliters) of blood, and is constantly working over a lifetime. Beating about 40 million times a year, a person's heart will beat approximately 2.5 billion times by the time of their 70th birthday.

1.According the passage, the underlined word “contender” in the last paragraph is closet in meaning to “          ”.

2.Which would be t he best title for the passage?

3.According to the passage,       .

4.What would be discussed in the following paragraph?

[1]It's safe, it's simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows．

[2]In what researchers claim is the first-ever trial of the effect of water consumption on weight loss, scientists from Virginia Tech found that dieters who started each meal with two glasses of water lost nearly five pounds more, on average, than dieters who did not, over the course of 12 weeks．There's no shortage of clear evidence about how water might work to control your appetite（食欲）．It ________________ so you don't eat so much; it keeps down your thirst so that you don't turn to calorie－rich sodas or juices．But until now, the researchers say, there has been no true evidence that water's appetite-controlling benefits ever translate into actual weight loss．Now there is． In the 12-week study period, dieters instructed to drink water with every meal lost an average of 15.5 pounds; dieters given no instructions lost, on average, just 11 pounds．

[3]Perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general．In fact, although doctors and public health authorities regularly remind us to drink more water, very few studies give any insight into what our ideal quantity may be．

[4]The new results today suggest that many people could indeed stand to drink a little more water than they do．But if you're looking to lose weight, be aware that it is actually possible to drink too much water, and you probably won't help matters any by drinking too much water at a time．In extreme cases, it can even be deadly．A couple of glasses with each meal, however, should be no problem at all for a healthy person．
