5.The best title (题目) of the passage is ___.

The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.

As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴莲). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.

Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.

Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.

One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.

1.Before the experiment, volunteers ______.

A．are gathered and take a training

B．cannot eat or drink for several hours

C．must wash their hands carefully

D．will be interviewed by Dr Finkelstein

2.If both men and women are asked to keep their hands in hot water while taking in some pleasant smells, ______.

A．women may stand the pain of the hot water longer

B．men may keep their hands in the hot water longer

C．they will probably take their hands out at the same time

D．we are not quite sure who will take their hands out earlier

3.From the passage we learn that _________.

A．the reason why women are sensitive to smells is clear

B．the experiment for the sense of smell has come to an end

C．unpleasant smells affect men’s senses more than women’s

D．scientists have not totally explained the result of the study

4.Now scientists believe that _______.

A．mothers recognize their children only by sight

B．men’s sense of smell developed a long time ago

C．strong smells have a great influence on people’s senses

D．smells are helpful for mothers to spot their children

5.The writer wrote the passage in order to ________.

A．supply some entertainment to us

B．show women’s sharper senses than men’s

C．inform the readers of some knowledge

D．call for volunteers for the experiment

Homemade Ice Cream in a Bag
Difficulty: Very Easy
Average User Rating:★★★★☆(4.3/5)
Milk can become homemade ice cream in five minutes by using a bag! This homemade, creamy treat is a summertime delight for your kids and you alike.
What you’ll need:
1 tablespoon of sugar; 1/2 cup of milk; 1/4 teaspoon of vanilla (香草香精); 6 tablespoons of rock salt; 1 small-sized plastic food storage bag; 1 gallon-sized plastic food storage bag; ice cubes.
How to make it:
l Fill the large bag half full of ice, and add the rock salt. Seal the bag.
l Put milk, vanilla, and sugar into the small bag, and seal it.
l Place the small bag inside the large one, and seal it again carefully.
l Shake until the mixture turns into ice cream, which takes about five minutes.
l Wipe the top of the small bag, and then open it carefully. Enjoy!
Tips:
1/2 cup of milk will make about one spoon of ice cream, so double the recipe if you want more. But don’t increase the amount more than that—a large amount might be too big for kids to pick up because the ice itself is heavy.
Here is another version of the homemade ice cream recipe from another parent!
These are the homemade ice cream ingredients:
1/4 teaspoon of vanilla butter and nuts; 1 tablespoon of sugar; 1/2 cup of milk.
These are the other supplies:
Plastic sandwich bag; 12 salt pellets; 1 dish of ice; large plastic bag.
Put the ice cream ingredients in the small bag, and then put the bag, salt and ice in the big bag. Hold the bag shut and move it around on the floor for about 5 minutes.
When I made ice cream at home last time, although the salt pellets didn’t really dissolve (溶解) that well, I still got ice cream. It was not smooth ice cream, probably because of the low-fat milk. It was incredible that it could be ready in 5 minutes (not counting preparing the ingredients)
Next, I changed the recipe, using a tablespoon of cocoa, a tablespoon of sugar, and a cup of milk. It was a bit too chocolaty, but good!
【小题1】The underlined “that” in “Tips” section refers to ____.
