Now we are fairly certain that we can easily get down to the ice table, said Peter Smith, a University of Arizona scientist who is the chief project investigator.The spacecraft is equipped with a shovel-like robotic arm that will be used to dig into the ground and retrieve samples for testing in the landers small laboratories. The lander was sent to a spot on Mars northern regions in hopes of finding frozen water, but just how deep underground it would be found was unknown.The robot arm is expected to begin its first digging operations after several more days of testing.Once the arm starts digging, dirt and ice it scoops up will be deposited in several small ovens to be heated. Measuring devices will test the resulting gases.The University of Arizona in Tucson is leading and NASAs Jet Propulsion Laboratory is managing the three-month scientific mission.1What was the Phoenix lander meant to do?ATo search for frozen water on MarsBTo explore life in outer spaceCTo study the minerals in the soil DTo discover new rsouzees in outer space2Why did NASA scientists feel worried about the finding?

After two years of walking she began to notice her right foot hurt and she was always adjusting her laces (带子). A visit to the family doctor resulted in her going to the last place she thought hed send her: a shoe store. Her solution was simple: new sneakers, fitted by a professional. Many people suffer for years without realizing their pain is caused by improperly fitted shoes and thats why its important consumers be aware of how to choose footwear. Here are some tips to keep your feet happy and pain free. Have your feet measured before you make a shoe purchase. Make sure you measure both feet, since most of us have one foot larger than the other. Always purchase shoes to fit the largest foot. Try both shoes on and walk in them before you buy. Sizes vary, as do styles and shoe shapes. A size 8 in one brand might fit perfectly, while a 7-and-half in another is too loose in the heel. Your feet swell during the day, so make sure you only shop for shoes in the evening. There should be a three-eighths to 5 inch space between your longest toe and the end of the shoe. The ball of your foot should fit comfortably into the widest part of the shoe. Before buying shoes of any kind ensure that the heel fits well and there is no slippage. Look for shoes that are similar in shape to your feet. Some brands and styles are narrower than others, or have a narrow heel. High heels can cause not only foot pain, but posture problems and back pain, as well. For these reasons women should avoid high heels. If you must wear them, never go over 2- and-a-half inches in heel height. Always buy shoes that fit now. Shoes do not stretch and there is no such thing as “breaking them in”. Wear the same type of socks or nylons you will be wearing with the shoe. If youre purchasing sneakers, wear athletic socks. For high heels, wear nylons during the fitting session.Make sure the shoes (1) _ your feetsituationadviceNeither this shoe (2) _ that one fits you.Make sure you measure both feet and purchase shoes to fit the (3) _ foot.
