【题目】Fun School Projects with Magnets and Metal

Science is one of the most interesting and fun subjects for kids.

There are endless opportunities for practical experiments that are sure to surprise and excite children's imaginations. A great way to get into experimenting with science is with the use of magnets. The properties of magnets allow for an “ invisible force ” to move objects seemingly on their own!

If your kids are looking for something a little trickier, why not let them try using magnets to make their own compass (指南针)?

For this experiment, you will need 2 needles, a strong magnet, a pencil, a cup and some string.

Step 1: Rub the pointed end of the needle along one side of the magnet ;this can be either the north or south end. Make sure you are rubbing the needle in one direction, not back and forth. You might need to do this about 30 times to magnetise the needle.

Step 2: Test the now magnetised needle with the spare needle to see if it can pick it up. If it can, the needle is ready to use for the experiment. If it doesn't pick it up, you will need to rub the needle a few more times on the same end of the magnet you were using before.

Step 3 : With a piece of string that is a couple of inches long, get your child to tie this to the middle of the pencil. Then, at the bottom end of the hanging string, tie the magnetised needle.

Step 4: Place the pencil, with the needle hanging down, over the top of a cup so that the needle is hanging inside the cup.

Step 5 : Watch as the needle moves on its own to point north.

Once your kids have got a taste for magnets, you might want to move on to more advanced experiments. Places like RS Components sell high-tech magnetic equipment that will be sure to carry on fuelling your children's passion for science!

1According to the passage, the spare needle is used to _______.

3What is the main purpose of this passage?

A.To promote high-tech magnetic equipment.

B.To entertain kids with magnet experiments.

C.To stress the importance of advanced experiments.

D.To provide a way to fuel kids' passion for science.

【题目】

To Machu Picchu and Cusco, searching for the lost Inca (印加人)city

Climb its towering staircases to a ceremonial temple set in the mountain face. These ruins mark the start of the 4-day Inca Trail to Machu Picchu, one of the world's most rewarding hikes. A quicker way to reach the remote Inca city is catching the train to the riverside town of Aguas and then jumping on a bus into the misty mountains.

Once the clouds rise from the mountain ridge above the Sacred Valley, the true splendor of Machu Picchu is finally revealed. It's a humbling experience to stand at an altitude of nearly 8,000 feet, and gaze down at the Inca city below. Overlooking the glorious ruins, it's easy to imagine the prosperity (紧荣) this peak must have been almost 600 years ago.

It's one of the world's greatest mysteries what became of the Incas who inhabited Machu Picchu.What was once major defense works in the largest empire on Earth was slowly swallowed by the jungle, only to be uncovered a century ago. The Inca dynasty has come and gone, but Incan families still survive in the highlands. These modern-day Children of the Sun still speak Quechua and continue to live off the land, although many come to Cusco to sell their crops and woolen textiles.

After dusk, when the story of the Incas becomes a whisper in the night, Cusco is covered under a starry blanket. A landscape so gorgeous that it deserves to be preserved for ever.

1The attraction of Machu Picchu lies in_____.

A.its towering staircasesB.its changeable weather

C.its natural scenery and cultureD.its wilderness and inaccessibility

2We can learn from the passage that_______

A.the Incas like to stay up chatting

B.Machu Picchu is a military base

C.the Quechua language is lost to the world

D.what happened to the Incas remains unknown

What elements pop up in your mind when you think of scientists? A pair of glasses, or a few wrinkles on the forehead? And do you think of a man, or a woman?

Well, as recently reported by BBC News, children in the US 1 women with scientists more than in previous decades, according to a new study.

“Draw a scientist” is an open-ended test designed to investigate children’s 2 of a typical scientist, and has been conducted by sociologists in various studies since the 1960s. After it began, a singular theme 3: most of the scientists drawn were men.

In the 1960s and 1970s, less than one percent of children drew a woman when asked to draw a scientist. But now, the number has risen to as high as 28 percent, given the fact that women’s 4 in the scientific workforce has improved significantly.

Jocelyn Steinke, a professor at Western Michigan University in the US, told the Washington Post “the study is important because it shows that children’s gender stereotypes(成见) of scientists have 5 over the past five decades in the United States.”

However, children are still far more likely to draw a(n)6 male figure when asked to draw a scientist. As found in the study, girls draw on 7 58 percent of scientists as men, with boys drawing 96 percent.

“The fact that children are still drawing more male than female scientists reflects their environment. Given the under-representation of women we observe in several science fields, we shouldn’t expect equal numbers. But 8, we can see that children’s stereotypes change over time,” David Miller, the study’s lead author, told BBC news.

The author of the study suggested that media stereotypes play a 9 role in children’s views of scientists as they get older. For example, children may determine 10 characteristics of a scientist based on certain aspects they see in the media, including a scientist’s sex or what they wear.

Meanwhile, as the Washington Post noted, gender stereotypes “exist across other professions”. For example, when asked to draw a teacher in another study, only 25 percent children in one study drew a man.
