What you're always heard? We're eating too much salt. The average American gets about 3.4 grams of sodium every day, far more than the upper limit of 2.3 grams recommended by the USD
A. The Institute of Medicine estimates that reducing sodium intake (摄取盘)nationwide could prevent 100,000 deaths every year.The headlines now? It’s time to get tough. The New York City health department recently kicked off a national effort to cut the amount of salt in packaged and restaurant food by 25% over five years. 80% of the salt in the average person’s diet comes from those sources, not from the saltshaker（盐瓶）.But wait! The benefits of salt reduction are surprisingly murky. At least 13 studies have tried to find out what happens to people who choose to eat salty or not-so-salty food—and the results have pointed in every direction. Some studies suggest that cutting salt protects the heart: others suggest that intense salt reduction can actually increase heart problems. What's needed，Dr. Michael Alderman says, is a randomized（随机的），controlled trial, in which people are put on different diets and followed for years. It’s the only way to get a reliable answer, but it’s never been done.So what should you do? Go easy on processed foods and eat more produce. Those changes will improve your diet in a variety of ways and cut the amount of sodium you consume. If your blood pressure is high, work with your doctor to control it with drugs and lifestyle changes. If your blood pressure is healthy? At this point, there’s no convincing reason for you to count every grain.1. It is stated in Paragraph 1 that our sodium intake（ ）.2. The main sources of salt in our diet are（ ）.3.

Janet（ ）“Good morning!” to the teacher and then came in.
During a trip to observe wild animals in Africa, I encountered the least brave animal on earth, the wildebeest (角马). I sat on a riverbank for three hours watching a group of thousands build（1） the courage to drink water.More than a million wildebeests（2）northward into the wetlands. It is a long, dry and difficult journey. Frequently, the only available water is the Grumeti River,（3）represents both life and death. Unlike some creatures that can take moisture（4）the grass they eat, wildebeests must drink from the river to live. The river supports other wildlife, including（5）that kill and eat other animals. Though thirsty（6）traveling, the wildebeests stand back from the water, sensing possible danger.Moving slowly toward the bank can（7）hours, as an individual wildebeest steps forward, steps back and then carefully steps forward again. More wildebeests gather together and advance, gradually pushing the leaders to the river,（8）they want to go or not. It’s been a long time（9）they drink last time, and you feel their anxiety for water.Lions are possibly on the（10）, saving energy as they wait for an opportunity for lunch. Once the large group moves to the river, lions could（11）, making the group running in a wild and uncontrolled（12）. The mad rush would raise a dust cloud that blocks the（13）of the wildebeests nearby. A kill is almost guaranteed.Sitting on that riverbank, I noticed that a young wildebeest finally stepped ahead and drank while the（14）adults held back. Soon, others began drinking. But（15）lining up along the bank, taking turns, they gathered and pushed. Some had to walk farther into the water than they were （16）to go. Those pushed farther in water got frightened and in（17）frightened the others. They all retreated hastily and returned to their route. Only the few that were（18）enough got a drink. The others went（19）. There was no danger that day. Only the wildebeests’ fear and（20）of courage kept them from drinking.
