Ladies and gentleman, tday I wuld like t intrduce Tu Yuyu t all f yu. Brn in Ningb, Zhejiang prvince in 1930, Tu graduated frm Beijing university in 1955. She wn the Nbel Prize in 2015, f whm we are prud.
Pssible versin:
What makes her a great pharmaclgist is that she devted her whle life t fighting against malaria. After hundreds f failures, she finally discvered the medicine called artemisinin because f her hard wrk and determinatin, which makes it pssible fr peple t get rid f maralia. Hwever, successful as she is, she desn't care abut being famus. Furthermre, she wuld rather keep time fr her study s that peple all arund the wrld culd benefit frm her research.She is a persn we Chinese all take pride in and we shuld learn frm her.
Lk at the pht belw, and discuss in grups what these activities have t d with science.
Activity 1
Lk at the pht belw, and discuss in grups what these activities have t d with science.
A I think the dish in this exhibitin is related t sund. Maybe the by is whispering int the smaller circle and the dish can make his vice luder.
B This lks like a pian yu play with yur feet. Maybe it shws hw sund wrks.
C I'm nt sure what this ne shws, but it must be abut light r eyesight.
D It is a hall f mirrrs. Maybe it has t d with the principles f reflectin.
E This is prbably an experiment invlving the cmpsitin f light.
Befre listening:
The phts abve are related t the cnversatin yu will hear. Using the phts, try t predict the answers t the fllwing questins.1. Where are the peple in the cnversatin ging t g?2. What kind f place is it, and what des it fcus n?3 .What kinds f things can yu d there?
Activity 2
 1 Where are the peple in the cnversatin ging t g? They are ging t a science museum.2. What kind f place is it, and what des it fcus n? It is a science museum that fcuses n letting visitrs experience science thrugh interactive learning exhibitins.3 .What kinds f things can yu d there?Yu can prbably try different activities t learn abut sund, light, reflectin, and s n. Fr example, yu can g t a rm with many mirrrs facing each ther s it lks like there are many cpies f yu! Or yu can play with a big pian n the flr.
While-listening Listen t the cnversatin and see if yur answers fr Activity 2 are crrect. Then write dwn the letters (A-E) fr the phts in the rder that yu hear them described.

1. The cnversatin is abut the City f Science and Industry, a museum in Paris. Wuld yu like t g t this museum? Why r why nt?
Activity 4
The reasn why I wuld like t g t this museum is that it is an amazing place fr us t have fun, learn, and get inspired.Just as the pictures shw, there is a lt f interesting stuff t d there. What I like mst is that I can participate in the interactive activities and explre the scientific phenmena fr myself.
2. Are there any museums like this in China? What ther interesting museums are there?Yes. There are ther interesting museums such as art museum r museum abut ancient treasure.
Make a shrt presentatin
Make a shrt presentatin t the class abut yur chice. Use the example and useful phrases belw t help yu.EXAMPLETday, I want t talk t yu abut a very strange phenmenn called a nn-Newtnian fluid. Yu can make it easily using equal parts f water and crnflur, like I have here. Ann-Newtnian fluid is strange because yu can pur it like a liquid, but if yu put any pressure n it, it suddenly becmes hard as cncrete. In fact, it becmes hard enugh t stand n. Then, as sn as yu take the pressure ff, it becmes a liquid again. This shws that it is pssible that smething can exist as a liquid and a slid at the same time.
useful phrases:Talking abut scientific phenmena.. can/cannt exist in the frm f a slid/gas and a liquid/plasma Is bth a ... And a.. . at the same time light/sund is reflected the existence f ther…This ccurs when yu will becme demnstrates ….This experiment/research shws. .. Thrugh this, we knw that can prve that evidence prves …
Tday, I want t talk t yu abut the psitive and negative charges f mlecules. We can demnstrate hw these interact thrugh a simple experiment using milk, dish sap, and fd clring. First, cver the bttm f a shallw plate with milk. Nw add tw r three drps f different liquid fd clring t the center f the milk. They shuld frm ne large dark puddle in the middle f the milk. Nw, dip a cttn swab int dish sap, and it int the middle f the fd place clring. Yu will see the clrs quickly mve t escape frm the sap, making interesting and beautiful patterns. This happens because the dish sap mlecules have a strng negative charge, and the milk mlecules have a strng psitive charge. Like magnets, these mlecules are attracted t each ther, and s they appear t mve arund n the plate, taking the fd clring with them, making it lk like the clrs are quickly mving t escape frm the sap.
Exchange yur draft with a partner.Use the checklist t give feedback n yur wn and yur partner’s draft, and then hand it in.(Each 1-5 pints)
