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 ____.

A.1/2 cup of milk

B.1 cup of milk

C.1 spoon of ice cream

D.2 spoons of ice cream小题2:Which of the following things is NOT included in both recipes?

A.Sugar

B.Ice

C.Plastic bag

D.Nuts小题3:Which of the following statements about the second parent is TRUE?

A.He/ She doesn’t agree with the first parent.

B.He/ She doesn’t think five minutes is enough

C.He/ She doesn’t like cocoa better than nuts.

D.He/ She doesn’t think the chocolaty tastes bad.

答案

小题1:B

小题2:D

小题3:D

题目分析:本文讲述了两个配方的家庭自制冰激凌的做法。

小题1:B 推理题。根据本句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说明1/2就可以制作one spoon,如果你还想多的,就加倍,那么就是一杯,但是数量不要再超过这个量了,那么这里的that就是指一杯的牛奶。故B项正确。

小题2:D 细节题。根据文章的两个配方可知都需要糖,冰和塑料袋,没有提及都使用nuts故D项符合要求。

小题3:D 推理题。根据This homemade, creamy treat is a summertime delight for your kids and you alike.说明在夏天这样的冰激凌对于孩子们来说是很快乐的事情,那么说明这样的冰激凌的味道很好,故D项正确。

点评:本文讲述了两个配方的家庭自制冰激凌的做法。此类文章的最大的障碍是词汇以及考生对阅读内容的不熟悉,需要考生在阅读的时候有足够的耐心,同上抓住文章的中心,不要受其他信息的影响。要根据题目及选项以及文章的上下文串联合理的判断推理。

氮是植物生长不可缺少的“维生素”,是合成蛋白质的主要来源.固氮菌擅长空中取氮,它们能把空气中植物无法吸收的氮气转化成氮肥,源源不断地供植物享用.在形形色色的固氮菌中,名声最大的要数根瘤茵了.根瘤菌平常生活在土壤中,以动植物残体为养料,自由自在地过着“腐生生活”.当土壤中有相应的豆科植物生长时,根瘤茵便迅速向它的根部靠拢,并从根毛弯曲处进入根部.豆科植物的根部细胞在根瘤茵的刺激下加速分裂、膨大,形成了大大小小的“瘤子”,为根瘤菌提供了理想的活动场所,同时还供应丰富的养料,让根瘤茵生长繁殖.根瘤茵又会卖力地从空气中吸收氮气,为豆科植物制作“氮餐”,使它们枝繁叶茂,欣欣向荣.这样,根瘤菌与豆科植物结成了共生关系,因此人们也把根瘤菌叫共生固氮菌.根瘤茵生产的氮肥不仅可以满足豆科植物的需要,而且还能分出一些来帮助“远亲近邻”,储存一部分留给“晚辈”,所以我国历来有种豆肥田的习惯.还有一些固氮茵,比如圆褐固氮茵,它们不住在植物体内,能自己从空气中吸收氮气,繁殖后代,死后将遗体“捐赠”给植物,使植物得到大量氮肥.这类固氮茵叫自生固氮茵.氮气是空气中的主要成分,占空气总量的五分之四.然而由于氮气分子被三条“绳索”______化学键所束缚,因此大部分植物只能“望氮兴叹”.固氮茵的本领在于它有一把“神刀”______固氮酶,可以轻易地切断束缚氮分子的化学键,把氮分子变为能被植物消化、吸收的氮原子.现在人类生产氮肥使用的化学方法.不仅需要高温、高压等非常苛刻的条件,而且还浪费大量原料,氮分子的有效利用率很低.固氮茵每年从空气中约固定1.*

本文的主要内容是()

A.固氮菌的“神刀”作用

B.两种“取氮能手”的功用

C.根瘤菌的“腐生生活”

D.氮是植物生长不可缺少的“维生素”
