读下列经纬网图,完成下列问题。

小题1:若a点比b点的时间早10小时,则(  )

A.a点在d的东北方

B.a点在d的西北方

C.bd的经度为90°W

D.bd的经度为30°W小题2:在ac经线上,由c至a,各地日出时刻越来越早,则(  )

A.北京昼短夜长

B.北极地区有极夜现象出现

C. * * 广场的升旗时间早于6点

D.此时是9月23目至次年的3 月 21日

答案

小题1:D   

小题2:C   

题目分析:

小题1:若a点比b点的时间早10小时,说明a的时区在b时区的东边,但不能说a在b的东边或西边,所以A、B错;bd的经度与a相差10小时,a为120°E,则bd所以经线度数应=120°-10*15°= -30°,即bd所在经度为西经30度,C错,选D正确。

小题2:在ac经线上,由c至a,各地日出时刻越来越早,c比a纬度低,日出时间晚;说明此时北半球各地昼长夜短,A错;北极地区可能有极昼现象,B错;北半球夏季, * * 广场升旗时间早于6:00,C正确;此时应在北半球的夏季,3月21到9月23日间,D错。选C正确。

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.
