1．Everyone has their favorite food.Some might love chocolate.Some might love potato chips.
Think about your favorite food.Have you ever wondered why your favorite food tastes so good？The answer is about your tongue （舌头） and your nose.
There are some taste buds （味蕾） on your tongue.They give you the sense of taste.How do the taste buds work？In fact，they have many tiny hairs on them.These tiny hairs send messages to your brain about the tastes of different food.In this way，you know whether it is sweet，sour，bitter or salty.
An average person has about 10，000 taste buds.They keep working all the time when we enjoy our food.The taste buds don't always stay the same.They are replaced every two weeks or so.However，as a person gets older，some of these taste buds don't get replaced.An older person may only have 5，000 working taste buds.That's why some food may taste stronger for you than they do for an older person.
Besides your tongue，your nose also helps you learn about the taste of food.Sometimes，strong smells can even confuse （使困惑） your sense of taste.Try holding an onion under your nose while eating an apple.What do you taste？

2．For many people，having a cup of coffee right out of bed is the best way to start a day.But a report from Asap Science says otherwise.
It says the worst time for coffee is soon after we get up.When we wake up，our bodies start to make cortisol（皮质醇）.Cortisol helps us to think clearly and be quick to understand and act.The cortisol levels（数值；浓度）rise after we wake up and climb to the highest in about an hour.So there are two problems when we drink coffee during this time： ①our bodies will make less cortisol，and ②the cortisol will make coffee less useful.And that's why some of us drink more and more coffee.
Then，when's the best time to have coffee？When the cortisol levels are going down，the report says.Cortisol levels are usually highest between 8 a.m.jye.ai 9 a.m.，between noon and 1 p.m.，and between 5：30 p.m.jye.ai 6：30 p.m.So if you want to have coffee，enjoy it after these times，and this popular drink will help you the most.

3．
（1）Bananas which are needed in this experimentBanana confusion
Here's an interesting demonstration（演示） of how you can't always trust what you think you see.
You'll need
●Two bananas that look alike and are
exactly the same length
●Ruler
●Crayon
●Five helpers
1 Put the bananas side by side on a table pointing in the same direction.
Mark"1" on one with the crayon and"2"
on the other.
2 Hold the bananas like this，with No 1 on top，show them to your first helper and ask which one is longer.
3 Turn away，move No 2 to the top，
turn to your helper and ask again
which is longer.
Repeat these steps for each helper.
People will usually say the lower banana is the longer one.
They may do that because they naturally compare the bananas where they are closest to each other.
They compare the short inner curve （内曲线） of the top banana to the long top curve of the bottom banana.
SOURCE：TNS.
A．have the same size
B．look alike with the same length
C．are totally different
D．have similar shapes
（2）Why do these helpers think the two bananas have different length？
A．Because helpers see them in different ways.
B．Because helpers usually think the one closer to them is the longer.
C．Because helpers compare them with different curves.
D．Because the bananas used in the experiment are totally different.
（3）What does the experiment want to tell us？
A．Seeing is believing.
B．Think twice before acting.
C．Seeing is not always believing.
D．Practice makes perfect.发布：2026/5/21 9:30:2组卷：8引用：2难度：0.5
