Are you having 1 salt You 2 not think so. But people in China eat on average about 12 grams of salt each day, that is much 3 than the 6 grams 4 by the World Health Organization. You could be eating too much without 5 it. Because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages.
What problems can eating too much salt 6 To answer that question, first let’s take a look at what salt is.
Salt is a chemical compound. Salt is made of sodium and chloride (钠和氯化物). Salt is used to 7 and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride 8 .
But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been linked to other conditions, such as heart and kidney problems.
If you want to 9 on salt, the good news is, there are plenty of simple things to do. Here are some tips.
Cut back on 10 salt foods.
Most foods contain some salt. But some foods such as cheese, bacon, smoked fish and chips are almost high in salt because of the 11 they are made. You can still enjoy them, but try to have them in 12 amounts, or eat them less often.
Choose reduced salt bread and breakfast cereals.
Bread and breakfast cereals are major sources of salt in the diet not because they are necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you are shopping, take the time to 13 the salt levels on a few similar products. And always try to 14 the ones lower in salt. Avoid 15 too much salt to cooking and at the table. It will be good for your health.

二、阅读理解
When you are busy with your schoolwork, you might find it tough to get enough sleep. We all know that not getting enough sleep is bad for our health. But it has been found that less sleep could even cause you to have fewer friends, the Guardian reported.
According to researchers from the University of California, people who don’t get enough sleep are less willing to socialize (社交) with others. They are simply too tired to go out.
The researchers did a small study. They tested 18 young people who just had a good night’s sleep as well as tested them again after a sleepless night. The participants watched videos of people with neutral (中性的) expressions walking toward them. When the person on the video got too “close” to them, they pushed a button to stop the video, which recorded how close they allowed the person to get.
The results showed that people kept the person at a distance of 60 percent further back if they hadn’t gotten enough sleep. They felt that their personal space was being invaded (侵占). But when the participants got a good night’s sleep, they allowed the person to get much closer to them.
According to lead researcher Matthew Walker, the less sleep you get, the less you want to socialize with others. In turn, other people may think you are weird and stay away from you. This can make you feel lonely and cause you to sleep even less. It becomes a vicious cycle (恶性循环).
So if you want to be a more sociable and popular person, sleeping well might help. “One night of good sleep makes you feel more outgoing and socially confident,” Walker told the Daily Mail.

According to past studies, some parts of our brains can be different in size. 43 used to think these differences might influence how well men and women think and do things. They found this by scanning (扫描) 44 brains. However, in most of the studies, researchers only scanned fewer than 100 people.
Recently, the UK Biohank, a big database (数据库), scanned the brains of 40,000 people in the UK, 45 new understanding. It showed differences between men and women in size for certain brain parts. About one-third of these parts were found to be larger in men, 46 another third were larger in women.
